Check the power supply output or try another power supply. Charge the battery in another computer and see if the computer turns on with battery power. If it does then look at FL1 on the bottom of the mainboard near the external power connector to see if the solder on the legs has cracks. I just fixed this same problem on a C640 by re-soldering the legs on FL1 because one was cracked and discontinuous. If you don't have good mechanical/soldering skills you might want to find someone who does. Be careful of heat on FL1 I don't know if it is heat sensitive but I used minimal contact time with the iron and let it cool off between legs and it worked fine.

New battery and still won't charge.


first, check that the battery connection isn't blocked by a sticker or something.
second: try disconnecting the battery and ac and hold the power button for 1 minute. then give the battery and ac another try.

let us know how it goes.

if it still doesn't work, time for a warranty 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)
