I just downloaded and installed BIOS v. 2.13 for my X61 with Windows Vista (I like to keep the computer updated). The first thing that happened after I restarted after installing the BIOS was that it overheated and Windows automatically shut down (to avoid damage to hardware?). It seems this new BIOS version isn't very well tested, just like so many updates from Lenovo. I cannot recommend updating to the new BIOS version.

I started having the same problem recently, with frequent instantaneous shutdowns. I have a 7764-CTO x61 tablet as well, a Duo L7500 CPU @ 1.6 Ghz processor, 2Gb memory, BIOS Version LENOVO 7SET36WW (1.22 ) dated 11-27-2008, and Vista Business.
Did anyone ever figure out the cause or resolution?

I have an X61 Tablet too (7764-CTO), and I've got the same problem, which definitely started after the BIOS update to 1.23.
I am in contact with a local Lenovo service, and they're trying to figure it out as we speak.
Didier, who is dealing with my situation, is eliminating all the possible causes of the problem. He has two ideas for now.
1) On Thursday he's going to remove a plastic element from the fan assembly, which is known to cause problems. Here is his description:

Hi Stansfield, and welcome to the Lenovo User Community!
Sorry to hear about your overheating problem.
You can scratch #2 if you have Vista SP1 or later. That hotfix, 937500, is included in SP1.

Darn, I've got SP2 even.
I forwarded your post to Didier from the service.

So, update, and quite a good one too!
Just got my X61t back from a few hours at the service. The BIOS problem was transfered to the Lenovo EMEA Engineering Dept, and typically there should be an answer within 2-3 days. I'll update you when there is one.
The good news is though that Didier replaced my fan assembly, and - what's most important - removed the plastic square element he mentioned earlier. I'm pretty sure that replacing the fan assembly didn't change much, as it was practially brand new (they've replaced it a few months ago as it burned down:/). BUT, the temperature is clearly lower now! Not back to it's orginal levels, mind you, but lower by at least 5-10 degrees! Before the operation the CPU on a standard load (a few typical apps running, so let's say 15-20%) was around 65 degrees. Now it hardly reaches 50-55! Really, I'm impressed how much this small thing changed the situation!
(just for reference, before the BIOS update the temp was around 45 degrees)
So, all you people with the overheating problem, if you don't want to wait for a software/BIOS solution (which will hopefully come too sooner or later), go to your Lenovo service and ask them to remove the plastic thingie from the fan assembly (and better replace the whole thing too, it's free anyway). It really did miracles to my X61!
Well, hope this helps! Cheers
PS. if you're from Belgium, go to Samap in Brussels and ask for Didier, he is the miracle worker here, as the idea was totally his! Bravo!

Dear All, hopefully I've got the final answer to the problem!
1.23 is not the latest BIOS, there is version 1.24 avaialble at our support pages:
Have they had a chance to test with this one?

I've just updated it, for now the core temps seem reasonable. 47-49 at idle, 54-56 at 40% constant load. I'm not sure though which helped the most, the removal of the plastic element from the fan assembly or the BIOS update..
Will let you know how my tests turn out

Just to confirm, been running some demanding apps for the last 15 minutes (video conversion etc), so the CPU load is constantly 96-100%, an the core temp doesn't exceed 67 degrees! Definitely not the 88 degrees it used to be.
