Comment 0 for bug 773716

As part of the Natty cert test on this system, I used the Slep Key (Fn-F4) this successfully put the system in Suspend. After hitting hte power button to wake the machine, the screen was very dark. I tried using the brightness keys to change that, but found that they now do not function. I then tried the battery key (Fn-F3) and that was also non-functional.

The volume keys seem to be working, but anything requiring the Fn key fails after this sleep.

Also, I tried running Power Manager to brighten the screen and that too failed to do anything, so now the screen is stuck at a dim level.
