  1. Hi,

    I have a Dell Latitude D620. I opened the case in order to clean the fan and change heat sink compound. Now, after turning laptop on, it shows the light for a couple of seconds and then turns itself off. CPU or fan don't even start running. Does anyone know what could be the problem? Did I disconnect something by mistake? Thanks in advance.

    Re-trace your steps there is something you have missed. Otherwise clear the CMOS or remove the backup battery for 30 seconds. DELL has some sort of fail safe on their hardware.

    Do as tipstir tells you but also make sure that you didn't leave any metal inside or didn't screw in a wrong screw in a wrong place, because that is a sign of a short circuit my friend... and that is bad new for you laptop...
    Hope you get it to work...
