T500: Spontaneous Hibernation

[ArtShapiro]

Have a 2082-3GU T500 that has gone into hibernation several times over the last few days while being used. It's plugged in and the battery is fully charged anyway.

It's running Windows 10 X64 and has been generally stable and problem-free.

Any ideas? I'm not losing any work, but it's rather annoying and unexpected.

Flaky lid sensor maybe? Might try disabling suspend on lid close and see it if it changes anything.

Weirdly I just saw that with my old T61p but I think it may have had something to do with HWinfo running. Hasn't done it since.

There were some open bugs recently in Win10 regarding spontaneous sleep. For example:

Do you use TPFanControl? I had the same issue with my T430 and Windows 10 x64. After uninstalled it, I had no problem.

Negative, but thanks for the suggestion.

Negative, but thanks for the suggestion.

My take would be to disable hibernation altogether if you don't use it on regular basis, especially if the system is running on an SSD.

My $0.02 only...

It's my normal mode of operation; even with the SSD the wakeup behavior is rather anemic - a far cry from the couple of seconds it takes my desktop machine to come up from the BIOS screen.

I have a bit similar problem. When the charger is attached to my T500 when it's closed and in sleeping state I find after some time that it has hibernated. That's very weird, does anybody know the answer why is this happening?
