X220: BIOS update v1.33

[sarbin]

g'day!

i see that v1.33 is available. my x220 came with v1.31 and is working ok, and, i'm usually in the "if it ain't broke..." camp especially on bios updates. looking at the readme though, i see:

[Problem fixes]
- Fixed an issue where specific hard disks might not be detected after resuming normal operation from standby/sleep state.
- Fixed an issue where an unnecessary fan error message might be shown.
- Fixed an issue where hang might happen at post with a certain USB HDD.

which seem significant enough to convince me to update. has anyone who has done the update seen any good, or ill, effects?

thanks!

Have not tried it because I'm still waiting for display brightness always set to max in BIOS screen fix.

Thanks, Bill.

I guess I'll add it to my to-do list.

Cheers.
