Latitude C510/610 Turns on, then shuts downLocked
I have Dell Latitude C510/C610 500MHz that my friend gave me to fix. The problem that he had is that when he would turn the laptop on, it would turn on for a couple of seconds, then it would turn off.
I tried everything from changing the battery, hard drive, power cable, etc. with known good ones. This did not fix the problem. I then began to open the case and found an infestation of roaches. I took the whole thing apart piece by piece cleaning everything with an electronics spray. I put everything back together and by miracle it turned on perfectly.
I had the laptop with me for about a month and it worked fine. After I gave it back to my friend, he told me the next day that the same thing happened to the laptop. I took it again and performed the same steps. Found new roaches in it. After I was done, it did not turn on again and this is how it is now. It will turn on and within a few seconds, it turns off. Nothing shows up on the LCD screen, no beeps, nothing. Any ideas?
