I recently flashed my BIOS (going from 1.26 -> 1.31) prior to installing Windows 7 x64 on a new SSD on my X220. The BIOS update seemed to work OK (I used the lenovo Windows utility to do it), but now I can't save any changes to any BIOS settings. I also cannot reset to defaults - I can't even select some options in the BIOS (e.g. anything to do with UEFI) - the cursor just skips over the lines on screen - and those I can select don't respond to any changes I try to make. I don't get any errors either in BIOS or in Windows, and my X220 boots OK, but obviously there's something wrong there.
After updating the BIOS, I installed the SSD (a Samsung 830) and installed Windows on it - all this worked OK although I was planning to switch to UEFI for the new install and couldn't do so because the BIOS is now uneditable. Everything in Windows seems to work OK.
I've tried re-running the BIOS utility but it reports that the BIOS is up to date and it won't re-apply the current update.
I've checked to see if anyone else has reported this issue here, and found a few reports with similar issues but different situations (e.g. people running Linux rather than Windows, or Wifi not working after the update) - but not this issue exactly.
I'm wondering if this will fix itself when a new BIOS version is released and applied - if that's likely, I'm happy to wait until then (so long as nothing breaks in the meantime). I'd rather do that than pull the CMOS battery (which has been recommended on a few similar threads on here) - but given that the BIOS seems to now be frozen on my machine I'm not sure if future updates will even work.
Has anyone else seen this issue?

Welcome To Lenovo Community
Please try updating the Bios using bios.bak file which is created during bios update .
You need to locate the bios file folder on c drive , then find bios.bak rename it with FLASHABLNew.ROM
And click on winplash.exe , use Browse option to " Specify new Bios file " and select FLASHABLNew.ROM
Then click on flash bios , it will flash a message that the bios you are trying to update is older than current version , Press Yes to continue
Press Yes , If every thing goes well , your system will restart and you will have your old bios were you can modify or change any option
Now delete the folder which has the latest bios
Download the latest bios and try to flash to check if you are able to modify or change any option under Bios
Hope This Helps
