display turns off after login when on battery

[montag42]

Binary package hint: xorg

Hello. I have a Sony Vaio computer with Ubuntu Maverick Meerkat. It is equipped with special keys ("Sony Vaio keys") one of which is "Display off" and which is functionning correctly and turning off backlight of display when pressed.

The problem emerges when I'm on battery. Just after the login screen, the backlight is turned off, just like when I press the "display off" button and I cannot turn it on back.
