    Compaq pressario m2000, has recently had the inverter replaced...

    symptoms are ...

    when on mains power can close the lid (or push the lid close button) and screen goes black, when I release the button screen lights up back to normal.

    when I disconnect the power adaptor and depress the screen close botton, screen black out, then when i release the button the screen comes up half bright for 1-2 seconds the goes black.

    whilst in this black state i reconnect the power supply, nothing happens until i re-push the screen down button and then let it go. Screen then comes up full brightness (ie. normal)...

    Have you got the latest BIOS? Sometimes problems like this are because of the BIOS.

    It might be that the backlight cannot regulate the brightness correctly or determine where to draw power from. I don't think it's software/bios related but purely hardware. Do you have problems when you pull out the cable with the lid open? Does the screen adjust brightness correctly?
    It seems to me like a bad connection, probably the repair was not 100% successful.
