I recently purchased a used x140e which runs Windows 10. It started to randomly shut off, with absolutely no warning. It recovers fine, boots up and I haven't really lost anything substantial as the recovery features on my programs seem to work well. That said, it is happening a couple of times a day and gets pretty annoying. I've already tried changing the power settings and I checked the fan, which appears to work just fine. Any thoughts?
