How to disassemble a Dell Inspiron 2650
Yesterday I took apart Fran's Dell Inspiron 2650. I took some photos along the way. This article should help ease the pain of anyone else who might attempt such a procedure. Click on any photo to get a larger version. These directions are unconditionally unguarenteed.

First things first. You'll need a small Phillips head screwdriver and a small jeweler's screwdriver. You'll also need a 5mm hex socket or wrench. The Phillips is for removing the gazillion screws that hold the freaking thing together. The jeweler's screwdriver is mainly for very carefully disconnecting the various connectors that you will come across. The 5mm is for removing the nuts on the serial port and the parallel port. Also get yourself a half dozen ziplock baggies and a sharpie. The baggies will be for organizing groups of screws as they come out of the machine. The sharpie is to label the baggies - so you'll remember which group is which. You should also get a roll of scotch tape. This is to tape certain screws to the parts that hold together. OK - Ready to start?

Step 1 - Remove the hinge cover. There are two screws that hold this in place from the back of the machine as indicated in the photo below:

Step1

Now open the display and from the right hand side (see arrow below) use the jeweler's screwdriver to pry up the cover. Carefully.


step2


Tape the two screws to the bezel and set that unit aside. Beneath the cover you will find a small circuit board held on by two screws (see arrows). Remove those two screws and place in a baggy. On the bottom of the circuit board is a ribbon cable. Carefully turn the circuit board away from you so that you can see the connector for the ribbon. Use the jeweler's screw driver to loosen the connector. Be careful! The connector has a lock which you must slide down (toward the cable) to free the cable. Once you have removed the circuit board, place it in a baggy with the two screws and set those aside.

step3

Now remove the 4 screws (marked below) that hold the keyboard in place. Place these screws in a baggy marked "Keyboard". There is a ribbon cable on the bottom of the keyboard. Lift the keyboard from the top. Carefully disconnect the keyboard cable from the motherboard. Set the keyboard aside. (Bonus points: what's wrong with the picture below??)

step4

Now you should be ready to remove the display. There are eight screws, so get a baggy and mark it "Display". First remove the two screws that hold the video cable to the motherboard and place them in your baggy. Carefully free the cable. Now remove the two screws that anchor the top of the display on the right. And then remove the two screws that anchor the display on the left. Place those four screws in the baggy.

step5

The remaining two screws for the display are on the back of the unit: one on the right, one on the left. Remove those two screws and place them in your "Display" baggy. Now carefully lift the display from the unit and set aside.

step6

Next remove the right hand shroud. There are three screws marked in the photo below. These are LONG screws; you don't want to loose them! So tape them to the shroud as shown. Lift the shroud out of the way and set it aside.

step7

You are done working on the top of the unit for now, so flip that sucker over and let's attack the bottom. First remove the floppy. Remove the two screws (marked below) and place them in a baggy marked "Floppy". Slowly slide the floppy drive out of the chassis. Remove the ribbon cable. This is the same type of connector as we saw earlier. I have marked the points on the connector which should allow you to unlock the cable. Slide the marked portion toward the cable - (ie in the same direction that you are moving the floppy drive. ) Once the cable is freed, then carefully pull out the floppy drive and set it aside with its screws.

step8

Now remove the single screw at the front center. This holds the hard drive. Once the screw is free, you'll need to slide the bezel on the front of the unit up (toward the bottom of the chassis, which I assume you have facing upward right about now). Got That? Then you can pull the drive out of the chassis. Screw your screw back into the door for safekeeping.

step9

Remove the two screws that holds the graphics processor fan. Place them in a baggy along with the cover. Carefully unplug the power cable for the fan. Now lift the fan out of the chassis and place it in the baggy and set it aside.

step10

Remove the single screw that holds the memory door in place. Slide the door away, and replace the screw in its hole.


step11

Remove the battery and set that aside.
Inside the memory bay, is a screw that secures the optical drive (CD-ROM, DVD, whatever...). Remove that screw (marked below) and press on the handle (marked) to push the drive out of the chassis. While you are at it, remove the cable for the modem (marked). Use your jeweler's screwdriver to gently pry it away from the unit.

step12

Get a baggy and mark it "bottom". Unscrew 12, yeah 12 screws (marked) and seal them up in the baggy and set them aside.


step13


Flip the computer back over. There are two screws on the top of the case (marked). Remove these and place in a baggy marked "Top" and set them aside. Remove the cable bundle marked on the bottom of the photo. Remove the screw (marked below) which holds the graphics card in place. Place that in an unmarked baggy. You'll need to pop the graphics adapter out; gently wiggle it until it comes out. Then place it in the baggy with its screw and set it aside. Now the top bezel should come right off.

step14

Remove the speaker cable (marked at the top of the image). Now its time to remove the floppy cage. Remove the two marked screws and tape them to the cage. Remove the cage and set it aside.

step15

Same song, different verse; remove the two marked screws that hold the Hard Drive Cage to the motherboard. Tape the screws to the cage. Both speaker wires are wrapped under the chassis and then they are run along the Hard Drive Cage. Carefully remove the speakers and free the wire off of the chassis on both sides. Then lift the cage and the speakers off of the mother board and set aside.

step16

Remove the four marked screws that hold the CPU fan in place. Lift the fan and set it aside.

step17

Home stretch! There are five screws that hold the motherboard to the bottom bezel. I don't have a photo without the CPU Fan - but one of the five screws lives just under the CPU fan. Remove these screws and place in a baggy marked "MB". From the back remove the four bolts - two on the parallel port, two on the serial port. Place these bolts in the "MB" Baggy. On the left side, there are two ports for audio. There is small plastic doohicky that you can lift out of place and stick that in the MB bag. There is another plastic doohicky that lives on the upper left corner of the battery bay. Stick that one in the "MB" baggy too. You'll need to work the flashing over the audio connectors. Congrats, you should now be able to lift the Motherboard off of the bottom bezel!

step18

At this point you should treat yourself to a fine Malted Beverage of your choice. I recommend a Big Ed's Triple Threat Munich Style Ale. Assembly is the reverse procedure, of course!

step19

Update Apr 28 07 - Moved the rest of the images to Flickr



Comments:
Chris, some of the pictures are missing from your 'how to disassemble a 2650' blog. Can this be fixed?
 
Sorry about that! Fixed!
 
Excellent Work on the Dell memory removal.

It made my upgrade easier. Much better than Dell support.
 
hi can you send me the file on my email address as most of the pictures are missing....I really would appreciate that....

khurram221@aol.com
 
I fixed the rest of the pictures. They are all now hosted on Flickr so there should be no more problems with the pictures!
 
I can not tell you how helpful this page was for me. My original graphics card went bad and I wanted to replace it myself. Without this page it would have taken me so much more time and harship to do it. In fact, I just finished the switch and my laptop is again working well. Thanks!!
 
Andrew -

Very glad that this helped you and congrats on getting the Graphics Card working once more!

Regards,

Chris
 
Just did an upgrade for my girlfriends computer and couldn't find anything on dell's site about the location of DIMM A. Thanks for the help!
 
> Thanks for the help!

No Problem!
 
Having taken the laptop apart, do you think it is possible to upgrade the graphics card with a 64MB card from an Inspiron 5150, as they appear a similar physical size?

Thanks,

Rob
 
Rob -

I suspect that upgrading the card is possible - but I have no firsthand knowledge about the requirements. I encourage you to forge ahead and please report back on your findings!

Regards,

Chris
 
No, the graphics card doesn't fit! Only option I can think of is to get a Dell motherboard that fits it. But then that brings all its own problems, like the rest of the components not fitting together!
I wonder if Dell know of any compatible components from later models? But I'm sure they won't tell because they'd want me to buy a new computer. Haha.

Rob
 
Hey Rob -

Here is a better option! I am pretty certain that the original graphics card is from NVdia. They can probably tell you if there is another model that will work. I'd bet that they have one! :-)
 
great work, Chris. I took the back off first when trying to fix the sound problem. I could not get to the sound card and gave up. I upgraded the sound drv, but its sound is still low, althought the sound control was maxed out. What do you suggest? Replace the sound card? Thanks.
 
Hi Sam -

The sound is integrated on the motherboard. Have you tried external speakers?

Regards,

Chris
 
Just wanted to say thanks for the detailed instructions - like jacb said, much better than Dell support!

Quick question - I get a continuous beeping on firing up the computer. One of the beep error code pages I've found says this is b/c the battery that maintains the BIOS RAM has died (though I can't find this error code list anymore - frustrating how info isn't always easily available). I took apart the computer hoping to find it but no luck. Any suggestions?

Regardless - thanks again. This has made the thought of doing upgrades by myself entirely possible.
 
Hmmm BIOS Battery...Good Question...To tell you the truth, I am not sure. I am about to crack this sucker open again, and when I do I will keep a look out for you.

-Chris
 
Thanks so much for this page; I'm trying to replace a keyboard for an Inspiron 2500, and your descriptions and pics are helpful. My problem though, is that I can't disconnect the keyboard cable from the motherboard. On sites describing some other laptop models, there's mention of "unlocking" the keyboard connector, but neither the Dell support docs nor your site mention anything like this. Do I just need to pull harder than I have, or is there a trick to disengaging this cable?
 
Note the comments about the circuit board cable connector in the section just before the keyboard:

"Use the jeweler's screw driver to loosen the connector. Be careful! The connector has a lock which you must slide down (toward the cable) to free the cable. "

This should be similar to what you need to do to free your keyboard cable!

Good Luck!

Regards,

Chris
 
Sorry for the long delay in replying; I was hoping to report success, but try as I might, I can't see where and how I might unlock the keyboard connector cable. I was hoping to switch keyboards between a couple of units (one good mb, one bad), but I guess I'll live with a few smudged keys. In any case, thanks for taking the time to post your suggestion for me.
 
My screen shows a distorted picture. its hard to see images, you see three of the same thing. ANy suggestions on what i could do to solve this issue?

ja
 
Everything looks good to me. What browser are you using? How much bandwidth do you have on your connection? Every photo has a link to Flickr - try clicking on the photo?
 
Chris, my dell inspiron 1000 has a screen that turns itself off intermittently. The computer is still running. Having looked around a few forums, it sounds like the ribbon cable that runs from the screen to the motherboard is loose and needs to be reseated (or is cracked and needs to be replaced). From your pics, an I right in presuming that the cable in pic#2 coming through the hinge (on the right hand side) and pic#4 or #5 is the one i should be looking for? Where does it connect? Anything I should watch out for? I've never done anything like this before, and am nervous about killing the machine. I can't afford a replacement :-(

Many thanks for any feedback you can give.

btw - your pics are excellent, and a real help.
 
Hi Simon -

Yes the cable shown in the picture labeled Step 3 and Step 5 is the right one - the cable with the red wires shown in the photo. In the Step 5 photo you can see where it connects to the Motherboard. The ribbon cable connectors have a small release and lock mechanism. Dont force them! I think you are the right track!

Good luck!

Regards,

Chris
 
Exquisitely helpful! Your sharp photos with corresponding meticulous instructions (and suggestions) helped my friend double the DIMM RAM on my Inspiron 2650 to the maximum 512. In so doing, my son can now record music more smoothly and in less time. God bless you! Live long and prosper!
 
Larkram - Thanks for the comments!
 
THANK YOU SO MUCH FOR THIS!! Would not have been able to replace the crashed HD without this!!
 
Thanks so much for this. I was able to replace the motherboard with the toasted USB ports (indispensible!) in about 2 & 1/2 hours. While I was at it, I swapped out the 128MB chip under the keyboard for a 256MB to get 512MB on the system.
 
Chris, my cousin had a Dell Inspiron 2650. I'm assuming she dropped it because it stopped working and she gave it to me. It's been sitting in her closet for a few years and the battery is shot, which I can live with (new batteries are $50 on ebay). The problems come in when it won't run off AC power and the bios can't see the hard drive. I tried swapping out the drive for another but it was a different make and was also not seen. Are 2650's hd specific? Or is there a hard drive connection that could have come loose that could be fixed without buying a new mobo? I was hoping to get it working as a beater for school, but if it's going to cost me 300-400 to replace parts I might as well buy a whole new machine.
Thanks for the great step-by-step!
-Matt
 
Matt -

As to hard drive specificity - most IDE drives should work just fine. There is no cable to the drive - its a soldered connector on the Mobo. If its been sitting for a while, I would try to either flash the bios or do a reset settings on the bios.

Good luck!

-Chris
 
Chris, thanks for the speedy reply. I tore the computer down to the mobo looking for the weak link. I noticed that the hard drive didn't quite reach the connector. The adaptor between the drive and the mobo was gone. This is only the second laptop I've taken apart; I didn't think to look for it. My cousin took it to some guy to get it inspected awhile ago. Hopefully he still has it...
Thanks again,
-Matt
 
yeah - thats a common component. you can get one of those from any place like Fry's or another computer/electronics type store.
 
Chris, I have a Dell Inspiron 2650 and having a problem with the display. As of today, the screen goes blank, the computer stays on, but if I close the display and push it back up, the screen will come back on but only for a short time and then it goes back to black. All my settings are fine, would there possibly be a connector loose somewhere? and how would I go about fixing it? I would appreciate any help.
 
My guess is that switch that detects when the screen is open is malfunctioning. I cant remember exactly where it is located. Its not in the pictures. Follow the instructions to remove the screen, check the connections and see if you can find the switch - then replace it or clean it! Let us know how it goes.
 
Could you tell me where the cmos battery is on the 2650? I have one that doesn't keep time, but not only can I not find it on the mobo, but can't seem to find a replacement either.
Any help would be apprecated.
 
The CMOS battery is located on the edge of the motherboard near the floppy drive ribbon cable connector. The entire motherboard needs to be removed to access it. And as if that's not enough fun it's a specialty battery with tabs spotted on it so it can be soldered in. I'm in the process of finding a conventional battery holder and replacement cell. If you have another solution I'd love to see it.
 
Memory Upgrade - My 2650 has 256M total, I see a 128M removable. So the internal must be 128M. How do you replace the internal memory
 
Dave -

Follow all the instructions down to where it says "Now the top bezel should come right off." Look at that picture - see the memory sitting there? Replace that one and zip it back up. No sweat!

-Chris
 
Great tear down description!!I was just given a fully functional 2600 and gave it to my girlfriend to use as a word processor/internet browser. Crucial.com says it has a 512MB RAM stick in the user access slot and a 128MB in the one under the keyboard. I also opened it to verify. Crucial and Dell both say 512MB is the max that can be installed. It seems to be working fine with 640MB. I also went to "control panel, system" and it is recognizing 640MB. Could it handle two 512MB sticks? What dictates how much RAM can be used? The processor is an Intel Celeron 1.2GHz running XPhome. Can the rules be broken?
 
Steve -

If the 128MB under the keyboard is not soldered on the motherboard then it can probably by upgraded to 512.

-Chris
 
Great pictures, wish I found this thread before I took mine apart - would have sved time. My 2650 starts up them shuts down, I tried booting from the CD system disk - still shuts down on it's own in less than a minute. It will stay on longer if the computer has been sitting turned off for a while. I'm guessing some sort of heat issue. Any suggestions?
 
Check to make sure that the CPU fan comes on and is running. Is it possible that you did not connect the fan wire when you zipped it up? If you took the CPU fan off, did you put some heat sink compound on it when you put it back on? Did you tighten the screws on the heatsink/fan?
 
Chris,

A friend of mine just received msg 0271 - Check date and time settings
Warning System CMOS Checksum bad - Default configuration used. F1 to resume - F2 to settings. This laptop has not been used in 6 months. The battery doesn't hold a charge. Does he have to try to replace the cmos battery. I'm not sure what you mean by the statement - it's a specialty battery with tabs spotted on it so it can be soldered in.. (is the battery soldered in? Any help you can provide is appreciated
 
Hey, I have been having some trouble out of my cd rom drive. The computer says its not there, even dos dosnt show that I have it. But sometimes when I turn on the computer (if im lucky) it just starts working? could a cable be lose? thanks for any help -Chris-
 
Any luck on the CMOS battery replacement? Mine's dying (the clock keeps stopping) and I don't have a soldering iron
 
Thanks alot for posting this. I would have never found that dim slot.

-Mike
 
You do not show anything about taking apart the LCD. My 2650 has a damaged LCD support arm to the keyboard area. do you know how I can get a new set of support arms for the LCD screen? Bill Cooke, snbcooke@cox.net
 
Bill - Try Ebay for the support arms.
 
OK, i've taken the mother apart. Now how do i fix the DC power jack?????
 
Marc -

Heh, heh! Yeah this is exactly why I ripped this sucker apart.

Certainly it depends on whats wrong with the current power jack. The best repair is to get a replacement and then soldier that sucker in place of the broken one!

Good Luck!

Chris
 
Dude! Thanks to this page, I also was able to resurrect my otherwise fine 2650 from a 18 month long bad video adapter induced coma!

With confidence gained fter I replaced the keyboard on my Eee PC 901 thanks to a youtube video, I set to work reviving my other two injured laptops.

Thanks for documenting your 2650 dis-assembly...only one on the net as far as I can tell.

Try a SN Torpedo Extra IPA on me!!! Thanks again.
 
John - Awesome!
 
Your instructions are very thorough, but appear to be aimed at completely field stripping the unit. I just want to replace the "user-inaccessible" memory. I don't see anything in the picture that looks like memory. Where do I stop taking apart to just replace that memory? Thanks in advance!
 
Great Question. The memory you are looking for can be seen in the "step 14 picture". (If you hover your mouse pointer over the picture it should say "step 14"). The memory is right in the middle of that picture under the massive heat-sink fan assembly and also under the graphics adapter. So, to get to that memory you just need to: 1) Remove the keyboard (Steps 2, 3, and 4). And then remove the shroud (Step 7). That should be it. Let us know how it goes!
 
Hello Chris, I can't thank you enough! The world would be a bett,,,,,,scratch that...a PERFECT place if there were more people like you out there. That was the first time (and I've done it plenty of times) that I got a laptop disassembled without making a mess of it. That was as good of a step by step proceedure for disaembly of a box, as any I've ever seen.....now, if I can just find a wiring diagram I'll be Ok! Right On, Chris!
 
Thanks Hap. Let us know if you find the wiring diagram!
 
Thanks Chris!

I unsoldered my (dead) CMOS battery on my Inspiron 2650, and by peeling back the tabs on it I could read the number: ML1220 3V rechargeable. If you google ML1220 there are plenty of places to buy. Note they come with different solder tab configurations. Ours is actualy the "vertical" type even though the battery is mounted horizontally.

Some websites say you can use the more advanced VL1220 in substitute. That's what I did and it's working fine for now.

Price varies a lot. I got mine from in the UK from Farnell, part number 1514218, £2.37.

NB. my old battery was reading 2.62V before I unsoldered it. That was enough for the CMOS clock to stop, though the other settings were still OK. If you've soldered electronics before it's not too tricky, but if you haven't then I'd recommend you find someone to do it for you.

Make sure to get the polarity right. There is a little + sign next to one contact on the motherboard. For me, my new battery went writing-side-up, yet the old one was the other way round. (I just used a voltmeter on the new battery to find which side was which.) The new solder tabs needed trimming to length and the top one bending down slightly to meet the board. They're just soldered to surface pads.
 
Hi Chris do you have any pics that refer to replacing the inverter board in DELL inspiron 2650? I cannot seem to locate it. Thanks
 
Mishcr - I am not sure about an inverter board. If you sort it out let us know. Follow these instructions to break down. If there is an inverter board, you will find it!

-Chris
 
Wicked awesome page Chris. Thanks for taking the time to do this for us and getting me out of Dell Hell.
 
J - Glad to be of service! :-)
 
Hi Chris, I have inspiron 2650. It recognizes the battery with full charge but as soon as I take out the ac power cord it shuts off. It just runs on ac power only. The battery is new.
Thanks
 
Tejay - That is puzzling...Are you sure that you have the correct battery? I wonder if the battery could be defective. Make sure that you have the most current BIOS update as well. Other than that, I am not sure.
 
hi, i want to reset the BIOS of my 2650DELL, but i don 't know where is the battery... :) i already have "disassemble" dell inspiron 2650... need help. THX
 
I have heard that it is possible to upgrade to a 32mb graphics card, and to 256mb RAM. I am using this model right now, and the 16mb card is starting to have troubles dealing with the many adds on the internet.
 
Chris,
I am getting ready to replace the top plastic lid cover on my Inspiron 2650. Any suggestion how to go at it?
Wonderful site buddy, keep up the good work
 
Top - Follow the instructions to remove the display. Then you can remove the little screw covers on the inside corners of the display (you can see one of these in the third photo. Then remove the screws and the display should come apart. Let us know how you do and any other tips!
 
Thanks very much for going to all the trouble to post these pics of the Inspiron 2650 disassembly process.
 
Thanks dude - awesome help!

Thanks for the step by step instructions. I too had to fix a loose power connector, this is the first time I've ever disassembled a laptop, but your instructions made it simple. Thanks again.
 
help! i am trying to disconnect the keyboard cable from my dell inspiron 2500 to no avail.

do i have to:
a) just pull it very very very hard until it comes off? or
b) push or squeez some mechanism at the base (in the middle or both sides?) to release the lock?

I have been trying to figure this out for many days but couldn't get it done. if i pull the cable too hard and rip the thing off, i am very sure the damage will be irreverseble. if that happened, i would probably have to throw the laptop away coz not worth the money to sent it for repair. been looking at the dell manual but it doesn't explain in detail on how to go about pulling the keyboard cable off the base.
anyway, thanks for keeping this thread alive - the info really help.

rusman (from Malaysia)
 
rusman,

I can't say I remember if there was a mechanism on the keyboard connector with 100% accuracy, but I don't remember the keyboard being difficult to remove, so I think it just a matter of pulling it out. The two most difficult connectors are the Disk Drive, and the connector where the power button is on.
 
acckk...Don't just yank out the keyboard cable! The outside edges of the connector releases forward (in the direction of the cable.) Gently work those loose and then the cable will come free!

Regards,

Chris
 
Hi Chris: great site and service you are doing to us ancient hardware users!

You mentioned to Steve Row that:
'If the 128MB under the keyboard is not soldered on the motherboard then it can probably by upgraded to 512.'

This is a bit puzzling as other comments indicate that the memory should clip out the same as the one on the other side. Are there two different types of mounting, and is there really any limit on the memory that could be added. If Crucial got it wrong, how do we tell what we can add? (Is Steve Row out there to update us?)

Cheers
Spamlet
 
Spam -

The memory under keyboard can be seen right there on the picture that says "step 14". The mounting is exactly the same as on the other side. The BIOS and chipsets will dictate how much RAM can be stuffed into there. If Steve got a 512 chip working in one slot, I suspect that 512 would work in both slots.

Let us know how you get on!

Regards,

Chris
 
Hi Chris: good to see you are on the ball as well as providing the handy guides.
Readers should note that I have had a further reply to querying Steve Row's experience with Dell.

They say that Steve must have been refering to a 2650, rather than the 2600 he stated. They say that the 2650 has a 'Pentium 4' (presumably meaning a Celeron version of one) processor, and has been known to take a gigabyte; but the 2600's processor is a 'Pentium 3' type, and can indeed only handle the stated 512.

Unless anyone here knows better...
(Crucial, by the way, despite me giving them a link to this page, still say only an approved dealer can change the hidden module.)

Cheers,
S
 
Thank you so much Chris this was immensely helpful for me when I attempted to locate that darn CMOS, I'm not exactly super experienced with this stuff and your helpful comments, pictures, and tutorial made a possibly painful experience into a more pleasant one. thank you again!

Please download them if you want to use them as I won't leave them up forever on my site. Your Blog here is awesome! Rich.
 
Rich -

Thanks. From the looks of your pictures, you have relocated the battery as well so that changing it out in the future would not require a full disassembly. Smart!

Thanks for the photos!

Regards,

Chris
 
Great tutorial, changing my internal ram was very easy using these detailed pics. (under 5 min) great work
 
Hi Chris.

Was so glad I found this.
So happens, I took it (my 2650) apart one time before when I added RAM. Dell's website says it can only use 512 Mb, though now some on this blog are saying 1Gb. That would be a nice improvement.
My issue is the display. While plugging in an external mouse and a regular monitor (instead of my HDTV), I (due to dry conditions in my apartment) static sparked the mouse port. After that, the computer no longer could project to an external monitor.
I don't know how to check what part got damaged. I'm thinking it's possibly the video card, but more likely the VGA port on the motherboard. What do you think about this?
Also, Dell's instructions for replacing the 2650's motherboard includes this:


HINT: After replacing the system board, enter the computer service tag sequence into the BIOS of the replacement system board.

"11. Turn on the computer.


12. Insert the floppy disk or CD that accompanied the replacement system board into the appropriate drive, and turn on the computer. Follow the instructions on the screen."


Could you explain the "HINT" and step 12?

Thanks Again!

Gaius
 
Hi Gaius -

There should be a service tag number on the bottom of the computer. I guess that on boot you can update that into the BIOS. There is no good reason to do that however.

Good luck!

Regards,

Chris
 
Thanks, Chris.

I don't know that entering that number into the BIOS would matter now, as this computer has been out of warranty for about 8 years!

Other than that, is this CD they talk about (on Dell's website) that "accompanies the replacement board" really a necessary part of the motherboard installation process? If so, what is the CD and where would I get it?

Gaius
 
> is this CD they talk about (on Dell's website) ...really a necessary part of the motherboard installation process?

I dont know. That seems unlikely.
 
Hello,
Thank you very much for this detailled documentation.
Cheers.

Hi Chris,

A big thank you for your blog on the Dell 2650 Laptop.
I could easily replace the screen of my 2650 American by the screen of my 2650 French and everything seems to work well.

Best regards from France

dear Chris,
I replaced my hard drive on my dell inspiron 2650 from 40gb to 6gb (6gb is 16 years old) and I don't want to buy a new one because it cost too much and when i booted it up everything was properly inserted but it said i didn't have a hard drive installed. can you tell me what i'm doing wrong?
 
Chris.. I'm dealing with a 2600 that I have been so carefully taking apart, trying to find the cmos battery.. In your photos, I haven't been able to determine its location on the 2650.. any suggestions..
 
Mereleigh - There are not photos here of the CMOS battery. It is located on the edge of the MB next to the floppy cable connector. Strip the whole system down the MB and then you will find the battery. On the 2650 it is soldered on.
