    Hi, I have a X60 tablet with intel 945 graphics; and vista business. I cannot change lcd brightness when waking the computer from sleep. I have the latest power manager, and driver from lenovo website.

    I believe the problem started when I updated the intel 945 driver recently. However, I am not sure if that is the case. Also, the power settings in the graphics properties are checked on. I tried checking them off but no effect.

    And when the brightness change works (Fn keys) after a fresh restart, there is a difference in max brightness on battery and AC - even on max performance where lcd brightness is set to full for both.

    Any ideas?

    have you checked brightness settings in the BIOS?

    I believe it's like that with most notebooks.

    For ThinkPads, you can make the max brightness for both the same; the setting is in BIOS.
