Yoga 2 Pro Black Screen after Bios Update

2014-09-23, 13:53 PM

I just formatted my yoga 2 pro, downloaded the drivers and ran the Bios Update. I followed the instruction on the read me, ran the .exe, clicked next/ok until the laptop restarted and if I'm not mistaken a red menu with a progress bar showed up. At that point I left and when I came back a few minutes later the laptop was turned on, the screen lighting was on but the display was black, the keyboard backlights were also turned on and everything else was off. The lights on/near the power button that signal if it's turned on and plugged to the AC are turned off.

 

It's been like this for over 30 minutes now, no signs of progress. Has this happened to anyone else before? I'm not very keen on turning off or unplugging the laptop while flashing the BIOS, but at this point there's not much else I can do.

I found the answer to my problem at

http://forums.lenovo.com/t5/Idea-Windows-based-Tablets-and/Yoga-2-Bios-Update-Crash/m-p/1322487/highlight/true#M11689

 

Now that I found that post I do recall the instructions telling me to turn it off manually when I updated the bios earlier this year. However, the current instructions do not mention it at all, perhaps they should be updated?

I just bought mine and this is happening. Though something ive figured out is that the computer is still working. I can run task manager using ctrl alt delete and run various tasks but the background is still black. When I go into control panel I can change setting and thing but the windows 8 interface just will not work.

 To which BIOS version you have upgraded?

No idea. The only update ive done was the one that happened when I turned it off after setting it up. It'll work sometimes but not always.
