T60 2007-AD1 - freezes while on battery and changing loc....

[jpapejr]

I used to have this problem on XP where winxp would freeze up shortly after leaving power. I eventually attributed it mostly to the powering off of the eth card (deep sleep something) and I disabled it. Other times I thought it to be related to the Active Protection thing on the HDD. Well now I have been getting it again on RHEL 5. Events are as follows

1. Disconnection from power, walk to conf room
2. Work fine
3. Get up and move back to my desk or whatever
4. Sometime between step 2 (sitting still) and this step the system is frozen, no mouse, no keystrokes, no Ctrl-Alt-F2 for text tty.

Any ideas?

BTW - T60 2007-AD1 Gnome/XGl/Compiz Fusion/ Core Duo 2.17Ghz, 4 GB RAM (3 usable)

Have you tried running an Operating System different than Red Hat linux this time? (Assuming you did not start getting the freezes immediately after moving to the mentioned OS)

Also make sure your BIOS is up to date:

BIOS update utility - ThinkPad T60, T60p.

You should also run PC Doctor system tests to diagnose any problems with your machine:

ThinkPad PC Doctor for DOS bootable CD - ThinkPad. (for DOS since you've linux installed)

Moreover, also run Memtest86 test on your memory modules.

In addition, also try looking into some troubleshooting tips on this matter from lenovo:

Try removing the Active Drive protection software. (or at least disable it)

Active protection does not run on my Linux machine... (really hate this prog on my windows machines....)

What you are describing is what happens to me alot. I just sent my t60p in for service. They replaced the planar board. Mine was over heating i believe.

Thanks for the reply. I monitor my temp and CPU freq scaling pretty closely becuse my T60 runs hot to (don't they all?). My temp generally does not get too high so I don't think I'm getting overheated and locking up.
