When i power on my dell laptop(model pp01l) it shuts right back off


you have a no post-no power issue... try to reseat the memory modules and try to turn the computer on with just one memory module first. if it doesn't power on, remove it and try the other one. if it still doesn't power on, motherboard needs replacement.

C640 power issue


To my surprise, dell provides dis-assembly instructions online: http://support.dell.com/support/edocs/systems/latc640/sm_en/sysboard.htm#1000473

I have the same problem but didnt see a bad solder (resoldered all connectors with no success). I may have a bad AC power supply or bad charge circuit - no idea)

Dell Latitude c540/640


Windows Vista is not supported on Dell Latitude C540/C640. There are no drivers for the hardware of this model. Many older computers have that problem. You can try Microsoft to see if they even exist: http://www.microsoft.com/uk/windows/products/windowsvista/buyorupgrade/upgradeadvisor.mspx
You might have to fall back to XP.

Same problem with latitude 640


You can buy a password form ebay or sell the unit and get rid of it or try to find a password generator on places like warez or some other place , but more than likely all you will find is some type of virus to screw up your c640.
Or you can post you email and I can solve your problem

Hi

Both Dell Part numbers 18THT and 5W299 are 8X DVD-ROM Drive Modules. DPN 18THT is compatible with Latitude C series and DPN 5W299 is compatible with Latitude D series. The two drives have different and incompatible connectors.

Your Latitude C640 is a C Series Latitude. You can therefore not use DPN 5W299.

If you need a DVD drive module, get DPN 18THT or an alternative Latitude C series drive.

Keyboard


This is a rather old question, but the solution might still be helpful to other readers.

I suggest you call Tech Support at Dell...

Several years ago, I worked on many Dell CPx 500 models in my work place. There was an issue that always involved a series of 4 or 5 keys (they were always the same keys) that would quit working and we had attempted to purchase new keyboards to fix the issue. It turned out, the real solution was to replace the 'motherboard' of the Latitude notebook!

Dell had knowledge about the keyboard/motherboard issue that we didn't know.
