Straight Circuit
The proceedure to swap in a new motherboard in a laptop?
I have a Dell Latitude c640 and the existing motherboard has a bad ram slot and the dc charger circuit doesn't work. Otherwise, it's fine. I intend to put a new motherboard in the laptop, retaining the existing cpu, ram and hard drive. Is it a straight forward mechanical swap (that is easy-I've done it before) or is there something I must do with the bios or software to make it recognize the new motherboard? I'd appreciate any advice before I tear into the job.
Thanks
I own a c610 and have had it apart a couple of times.
first thing you want to do is go here and download the pdf service manual:

it's important you follow it in order, these things have to be taken apart in the correct order or things get broken and don't go back together so well. it's pretty much a mechanical swap, the bios is on the motherboard. The manual is pretty easy to follow, it has plenty of illustrations so a third grader can read it. Also, the screws are different types, you want to make sure you put the screws back in the right holes. there are 3 or 4 different lengths keep them seperated.
If I remember right, the order to take it apart is battery and cd drive, flip it over unscrew the screws labeled K flip it back over, unplug and remove keyboard, then you take the display off, then flip it back over, unscrew the keys labeled P, then remove the palmrest, then you have open access to the motherboard. that's the readers digest version, but download the manual anyway! good luck and have fun.
