The generic reset is noted in full in the CNET Laptop Troubleshooting Forum so here's the short version. Remove AC, Battery, press and hold the power button for the full 60 seconds, release and try again.
If that fails you are likely looking at changing the motherboard.
Hi all, i'm new to this forum and was hoping someone could give me a little help with a problem i'm having with my Dell Latitude C810. For starters the charger needs to be plugged in before i can do anything, and then from there all it will do when i hit the start up button is.........the light comes on for a split second and then off along with the backlight for a split second and off again. And that is it! I tried the same procedure with the battery out and the same happened only the battery light wasn't on obviously. I would really like to get my Dell up and running again even though it's a bit dated now. Any help on this would be greatly appreciated.
