Hello future Googlers! I managed to figure this out as the previous suggestions posted did not work for my tablet (thinkpad tablet 2 Compliance ID: TP00043A) What I did was (using the original AC adapter and usb cable plugged in to power): plug in the power using a straightened paper clip, insert it into the hole on the bottom edge of the tablet to the left of the docking port until you feel it click hold for 20 seconds remove clip unplug power cable insert clip again and hold for 20 seconds plug power back in press top power button hope this helps!
