    Hello Jaycraw28,

    Other thank the BIOS installation problem, I am not experiencing any other issues. In fact, I am extremely happy with my purchase, and I have decided to ignore the BIOS issue, as the computer is otherwise operating flawlessly.

    However, if my unit were having all of the issues that your unit is experiencing, I would probably take it back.

    Have you installed all of the available updates (other than the BIOS, of course)?

    Just my 2 cents - your mileage may vary. Good luck!

    Cheers, Ken

    Yeah, maybe I'll trade it out for another system. I did install all of the Windows updates and also a driver update for the graphics card.

    Oh one other thing, I upgraded the memory to 8gb. I wonder if that could be the issue for the problem I'm experiencing with the cpu restarting when coming out of hibernation I'll drop it back down to 6 gigs and see.

    ^ run memtest86+ to check your memory.

    UPDATE:

    After much research (and a little help from Sony) I finally figured out how to update the BIOS.

    It involves modification of the "model.txt" file in the Windows directory. Sony tech support originally suggested this but were very vague.

    As you may or may not know, Sony uses a file in the Windows directory called "model.txt" as a check to guard against incompatible software installations & upgrades.

    Sometimes this file gets written over, or contains the wrong model name. In my case, it contained the correct model name but for some reason the bios installation package would not recognize it and therefore would not allow the installation to take place. After much research I determined that, for some reason, my model number (VPCSC31FM) was not included in the installation database, although I verified beyond a shadow a doubt the the Bios was compatible with my unit.

    Following some directions that I found elsewhere on the Web, I changed the model number to another compatible model (in this case to VPCSC1AFM), and voila, I was able to perform the update.

    The best part is that it seems to have resolved the two issues I had - fan noise, and not recognizing the primary battery with the second battery pack ("sheet battery") installed.

    All is now well in Vaio land. Thanks to all who participated in this discussion.

    Cheers!

    I guess one of you posted the resolution to resolve bios R2085H4 issue, by updating the model number to VPCSC1AFM in model.txt. In my case the bios was installed by sony remote agent manually. Meaning he used universal extractor on the downloaded file to extract files and executed it. Now my system shows new bios.

    But the problem with my machine did not resolve. The system restarts after resuming from Sleep/Hebernate/Shutdown 50% of the time. Not always. I tried installing Sony notebook utilities, restored to factory settings couple of times, but nothing helped.
    Any clues ?
