[ltp] T60 intermittent freeze

[Philippe Clérié]

Hello all,

As the subject says, my T60 intermittently freezes so bad I actually 
have to turn off the computer and reboot. Can't even get the keyboard 
to work. Network also freezes: can't ping or login via ssh or telnet 
which I setup specifically for that.

The lock ups are very random. But they are much, much more common when 
I'm running on batteries. On batteries, I get about 6 freezes on a full 
charge. When connected to standard power, it only happens once, maybe 
twice a week. 

It always happens the same way. There are always a set
of horizontal black lines approximately 1/4 in apart extending only 
75/80% across the screen. Sometimes there'll be a loud beep. Once, I 
had random noise on the speaker. 

I cannot reproduce it at will so that's about all I can say to describe 
it.

Hardware: 
T60-1953ETU.

and 945GT Express Memory Controller Hub (rev 03)

Thanks in advance for any help!
