Power Manager and LCD Brightness, System Freezes, and other Problems

I have a brand new X200 with PM 1.54.  At first everything was working great.  Over the past few days I've noticed a few things:

 

1.  When running on battaries, the screen brightness changes about every 10 seconds even though the profile I'm using has that feature turned off. 

 

2.  After running the computer for about 1/2 hr, suddenly the PM shows a dramatic reduction in amount of time left on my battery which coinsides with: 

 

     a) fan consantly running; AND

     b) about 10 minuntes later my entire system freezes and I have to push the power button to force a reboot. 

 

Any ideas what's wrong?
