BIOS 208 - R2H208AS.zip
Workaround H/W to disable C4 at battery mode to avoid that system will hang up at sleeping to s3/s4
I wouldn't recommend applying the BIOS Update unless you know what you're doing and you're experimenting the particular problem. See this article for more details on S3 (Stand-by) and S4 (Hibernate) states.

I second Dan's warning to only do this if you know what you're doing and if you need it. I and one other owner now have completely dead R2Hs after applying the update. I have been doing BIOS updates at home and as part of my job for 9 years, and, despite my knowing that this kind of thing can and does happen, this is my first failure. I have an RMA.
