I have spent a few days reading through many of the related threads on this, as to not ask repetitive questions, but I'm left with concerns about proceeding based on where I'm at now.
I'm a few weeks into enjoying this new laptop and I've done a couple things this weekend, that I don't believe are related:
Upgraded primary HDD to Samsung SSD and moved original HDD to 2nd bay.
Used this forum to correctly do a clean install of a Win8 PRO DVD I got on student discount, did the PID.txt file and everything appears to be perfect post install.
After the install, I believe this was just the first time I noticed this, while I typically use DC power, today I was in another room on AC and letting Windows do a huge pile of updates since my clean install, and I noticed it took a lifetime!
This prompted me to review all the threads about BIOS 208 and the sticking of the CPU at .77GHz, which is exactly what mine does on AC, vs roughly 2.8GHz or more on DC.
I took instructions from threads and started by downloading the WinFlash utility from ASUS and the BIOS 208 file.
First I went to install WinFlash, and I get an error that it's only compatible with an ASUS notebook, which I have, but guess it doesn't see it that way due to the clean install......so that's as far as I've gotten.
My main question is this, I typically run on DC power and this thing has otherwise been an excellent machine to date.
While I'm willing to spend the time to research and learn new things, I'm concerned about the risk of "bricking" a $1500 laptop. I've built a desktop myself before, 6 years ago, and the SSD/Win8 Pro deal went well, but I wouldn't consider myself a talented tech guy otherwise.
Am I better off living with the slow performance on the few times I run on AC power, or is there hope that I could update the BIOS to 208 (I've verified I am running 207 today) without trashing this thing?
Appreciate any feedback and while I've read a lot of the threads in this forum, perhaps I missed one about the "non-ASUS" notebook failure on WinFlash, or someone has other advice.
