I just bought used x1 carbon gen 2 from a lady on craiglist. She said it just need ssd for she have it took off the ssd for her personal info. I turned it on. It goes to bios, it tell me the system info and all. While I wa driving home I was playing around with it and hit memtest. I tried to quit the process but it freezes there. I waited couple of minute and still freeze so I had to force shut down it. When I turned it back on. It just blank screen but lights are on. The light still going on and off then stays on. Even the touchpad on the very top where F key are still on. Then randomly shut off by itself.
using external monitor - no luck
I disconnected power adaptor and battery and hold power button for 30 -60 sec still no luck.
I disconnected cmos battery for 1 min still no luck.
I pressed the reset button underneath where you use paper clip and still no luck.
I thinking probably since I force shutdown while it doing it memtest which it freezes it cause the laptop black screen ?
Or it really has bad mobo to begin with?
I been trying to contact the lady and she never response back.
Any other test to make sure it’s a mobo problem before I toss it away? I spent $100 for it....
