Could that potentially fix the problem? If yes, should I press OK on the following message (see attachment)? (How likely is it that the update will fail, and is there a way of recovery?)
I recently upgraded mine from F2 to F3 using that utility and it worked fine. You can backup the current bios, but I'd make sure you put it on a USB key rather than just leave it on your desktop as I did - if the update had gone wrong how would I have retrieved the old BIOS?!
