Comment 17 for bug 667405

After some investigation, the BIOS for the R700/R705 (or some models of it) is identical to the R630, and the US site offers a bootable ISO as a means of performing the update. So, I grabbed that and ran it.

The file can be had from here: http://cdgenp01.csd.toshiba.com/content/support/downloads/t310v180.exe or via the downloads section on this page: http://www.csd.toshiba.com/cgi-bin/tais/support/jsp/modelContent.jsp?ct=SB&os=&category=&moid=2682552&rpn=PT310U&modelFilter=R700-S1310&selCategory=2756709&selFamily=1073768662#

This worked for my R630-13F.

The US BIOS update pack includes various methods. I diff'd the windows executable updater with the one offered by the UK site to verify they were identical, and so assumed the ISO would contain the same BIOS :) I suggest people at least do the same for their models just to be sure... of if you have windows dual-boot, just use that!

As for whether it's fixed the problem for me, it's too early to tell, but the thermal limit errors have gone from dmesg, so I'm hopeful.
