X200 Tablet notebook won't start after BIOS Update

Question

I have LENOVO X200 Tablet and I ran the BIOS Update and the computer won't start after the BIOS update. When I ran the BIOS update utility it ran everything fine and asked to restart the computer but it wont start screen is blank. I unplugged the power and took of the battery and put them back and still not starting.

Now it has [Power On] indicator light on and screen is not starting. I tried pressing F1 button while trying to start the computer but it doesn't do react to anything.

Please help how I can start my Tablet.

The update utility is http://support.lenovo.com/en_US/downloads/detail.page?LegacyDocID=MIGR-70651

Does any body know if X200 have any kind of hardware switch to reset the BIOS or any thing? What would be the best way to fix my BIOS?

Thank you.

Answer 1

First thing to try is remove the AC cord and battery, hold down the power button for 30 seconds, plug in AC only see if you get a post screen.

If this does not work, then you will need to do a crisis recovery, google "bios crisis recovery X200"

Answer 2

I've just had exactly the same issue - i.e I had flashed BIOS to latest version (the Lenovo supplied windows exe BIOS reflash version for X200) and on reboot (which was prompted by the completed reflash program) the machine will power, flash a few of it's lights but will not proceed into POST, just a black screen, no logo, no disk activity, no further.

Suspecting corrupt BIOS user settings, I removed the battery pack and AC power, removed keyboard and wrist rest to get at the CMOS battery (CMOS battery is under the keyboard, but its connector is actually under the wrist rest), and unplugged the CMOS battery for 5 minutes or so (just to be sure). Plug the CMOS battery back in then reattach keyboard and wrist rest.

Machine was then able to boot past POST with the latest BIOS now working fine - you will however get a warning message about lost Date and Time settings - which you can now reset manually.

I have pretty much the same problem. I'm trying to find a long term solution, but there is a simple short term one.

That is to just let your laptop wait to boot. It can take anything from 5 - 30 minutes to boot.
