Thinkpads Forum

About once a week or so my ThinkPad x240 freezes. It just completely locks up and requires a hard reset. The behavior does not seem related to time since the last reboot. It may happen a little more often when unplugging quickly from an external monitor, but not always. Is anyone else having a similar problem, or found a solution?

System Details
Model: 20AMSOSA08
Processor Intel i5-4300U @ 1.9 Ghz, 2 Cores
Memory: 8gb
OS: Windows 7 Professional 6.1.7601 Service Pack 1
BIOS: LENOVO GIET74WW (2.24)

To start, I would burn a linux distro, such as linux mint, to a bootable usb or dvd, then try booting off of it. If you get the same freeze, then there may be an issue, like malware in windows, or a faulty drive. However, more tests need to be done to verify it.
