Easiest BIOS update I have ever experienced.
Lenovo T420 'Thinkpad'
Unsolicited on-screen message: do you wan't to update BIOS
Me :yes
Message changes to: Do not use, switch off, or unplug until we tell you OK to.
.

.
(about 5 minutes elapses)
.
.
.
Message changes to: BIOS has been updated. check your settings/ Normal use of machine can be resumed.
Doesn't get much better than that, does it!
