    Display goes black when WIFI button is ON / compaq presario V5207NR

    Hi,

    I recently updated to ubuntu 12.04.02 LTS (after removing windows 7 and XP) on my compaq preasio V5207NR laptop.

    It was first a problem getting my WIFI to work properly, but with the help of ubuntuforums specialist it is now working.

    However, another problem came out from here and namely - when WIFI button is ON (flashing blue), then motior goes black and vice versa.
    Explaining: when i push the wifi button ON, then at the very same momment the screen turns black. I think only the backlight turns off as i'm seeing (hardly, but still seeing) some shadows of icons and the desktop at an apropriate angle. I can also see and move the pointer and the PC if fully operational...however cannot see a darn thing
    Thereafter when i hit the WIFI button and switch it OFF, then the backlight of the monitor turns on again and everything is OK, exept the WIFI is OFF

    My attempts to increase to increase brightness by FN keys were to no avail.
    I can execute commands in the terminal (while display is black) and paste results, if needed.

    P.S.
    To be honest, i had the same issue with the windows(es) (XP and 7) and when i moved to UBUNTU everything was fine ... until the WIFI started working

    Just to amend that recently i added 512RAM so i thought the problem might be this additional RAM memory is faulty. So today i removed it but the problem still persists.

    Any clues?

    I noticed that my battery metter goes rapidly down when power cord/charger is removed.
    Could it be the WIFI button is shorting out?
