I had this issues for a while now on my T420, when I'm using it on battery sometimes it just hibernates due to critical battery level even tho it has plenty of juice left. It doesn't happen 100% but it does happen at least like once with 10 times battery use.
The battery level when it hibernates vary, sometimes 90% sometimes 30% sometimes 50% etc. Normally it shuts down when battery is under 00:05 min and that's the setting I left it on.
New system did not solves this, and it does not hibernate on AC power. all drivers are the latest.
Anyone that have a fix for this? thanks
