    Hello,
    This is perhaps the most mysterious problem that has happened to
    my laptop.

    Problem: Once pressing the start button, it doesn't start up.
    The cpu light display doesn't respond, neither does the screen (which is not even "on", but black,) neither does the keyboard, caps lock etc. But, the lights on the wifi + bluetooth and the light around the start button is on.

    I've tried the whole "remove batter + power, hold the start button for 60sec, put back the batter" and nothing.

    Some Background:
    I recall this happening 3 other times. Each time having to do with my external harddrive. I remember the exact same problem occuring from some interference with the harddrive, and then my laptop miracolously works the next morning. I.e. being off for ca. 9-12 hours. This time when it happened, I plugged my external harddrive in while the laptop was starting up. Once the laptop was up and running, the laptop couldn't "see" the external harddrive, so I switched it off and the problem started.

    Some info:
    The external hardrive is plugged in via a usb cable, I use vista 32bit...

    Any suggestions?
    Thanks a lot!

    Some extra info..
    Now I left the laptop off since I last posted,
    hoping that it would miracolously work again,
    but it isn't... **** seems really screwed? =(

    The only way to test mb is to take laptop apart and remove the mb and connect it to an external monitor with just the memory installed if it posts then it harware if not its the board

    None relating to this problem. The only thing was the external harddrive, which caused a problem before, but after being switched off for a while, it would work again. From that angle it could be the bios?

    But the whole starting up thing is weird.. The CPU should be fine, as it shows activity when I use the CD drive...
