    I have a Compaq Presario CQ56 laptop that won't turn on. I've tried taking out the battery and unplugging it, holding the power button down for a minute then putting it back together again, but this does nothing. Any suggestions? Thanks.

    Do a dancing with RAM. take 1 stick, put in different slots, the same with another stick. Try to turn it on every time replacing stick

    Thanks for the reply but Replacing/ mixing up RAM didn't help :(

    Some of the buttons on the keyboard stopped working and the battery was taken out/ power button held 30 seconds/ replaced (which is supposed to clear any static electricity). So it doesn't seem like anything has been done directly to the hardware/ software to suddenly cause this problem.
    I've taken the laptop apart and looked at the mobo, it seems fine. I'm going to clean it up a bit just to make sure. So either:
    1) The mobo (or part of it) is dead
    2) The adapter provides enough voltage but does not provide enough current (in which case I will need something to test the current or rent/ buy a new adapter to to test)
