I'm having a customised Lenovo x220 product 4286CTO
I just love it, but now I'm suffering on a sudden laptop hibernating issue
For example I'm just working as usual and my battery is about 60%
then it shows me a warning that the battery is critical low and I need to save all unsaved data, but then this message dissapears and I'm working as usual for 4 more hours
or the system just suddenly hibernates and shuts down
Then I jusy start it again
While booting windows shows alert that the battery went critical and the system has been shut down to prevent lost of information.
After that it boots and the battery is still 5 hours long http://levanid.ru/upload/lenovohibernate.jpg
I'm facing that issue twice a day already...
It happened again while I was writing this post
Could somebody help me with that issue? I'm havnig 9cell battery I did already battery reset with Lenovo Power Manager but no use and that issue drives me crazy. At least I'm not losing any unsaved info cuz the system restores normally.
I'm on latest BIOS 1.17
Battery is SANYO Serial 4440 FRU P/N 42T4940
Please help me with that issue, I would gladly provide you with any information you need

Lenovo replaced the battery for me but the problem stil exists.
The x220 is suddenly hibernating due to a critical level of battery.
Quick forum search shows that the problem exists not only on x220
And there is still no solution avaliable.

...plus an extremely detailed description of the same issue with W510 http://forums.lenovo.com/t5/W-Series-ThinkPad-Lapt
My own X220 -- configuration 4290RV5 with BIOS 1.17 -- suffers from this problem as well.
It would be great if anybody from Lenovo Support crew communicated this issue to their Engineering Team for a deeper investigation.

Battery is defective, most likely has one or more weak cells, which lose their charge rapidly instead of gradually.
Since your laptop and battery are new, call Lenovo and they will send you a replacement.
once i replaced lenowo battery by warranty.
with new battery same problem with sudden hibernation exist as well.
so all lenovo battareies is defective? any official comments?

I am not sure whether or not it would fix anything but make sure you flash to the latest BIOS just to make sure that doesn't fix it. Otherwise try and uninstall the Lenovo Power Manager and see if the Laptop still hibernates with using just Windows.

It seems that TPFanControl might be the issue - I'll shut it down to check if eveyrthing would be OK
Q: Running TPFanControl I encounter strange spontaneous actions as shutdowns and standbys. Is there any workaround?
A: Newer versions of Thinkpad Power Manager don't team up with TPFanControl well. You can avoid these spontaneus effect by unistalling Thinkpad Power Manager Program and Thinkpad Power Manager Driver. For testing purpose saving the installation of Thinkpad Power Manager run autoruns with admin rights, uncheck all checkboxes of Thinkpad Power Manager instances as program, service and driver, and have reboot. To reactivate Thinkpad Power Manager check all checkboxes of Thinkpad Power Manager again and reboot.

Something else you can try is to disable Hibernate all together and see if it goes to sleep instead or if that fixes the problem just to see.

Might not help always. Sometimes the computer turns to standby.
First of all please look for the origin of the problem and do not fight against the symptoms.
Also have a look onto this posting.
