N100 BIOS downgrade (USB voltage problems and charger battery)

[gavron04]

I have 2x1GB.

I checked (1x1GB, second memory i've lay off) in Memtest86 4.0 and nothing wrong with RAM.

I've seen this article. I'll format my OS to other and check the bios.

"Hey!!!!!!!!!
I am sorry, I forgot to tell you about that problem too
The solution is simple (although I know you might freak out) and its not that long.
The idea is that you will have to flash your BIOS with the C200 check the file 63af02us (I know its wierd but don't freak out - trust me, the only error you will get is invalid model ID or something like that at the startup screen no harm at all (just to make sure that everything goes fine the BIOS is compatible and it will pass the check by the flash tool). When you get to windows, you might experience a change of resolution).

Now when you get to windows, just forget about all drivers that windows is trying to find and all the mess which is there, then simply flash your BIOS with the correct file (the one that you failed to flash).

Once again, trust me I know its wierd but its the only way.

Tell me about how it went !"

Works perfect!

I flash BIOS with 63af02us. Next new 3.12 version. And all works. But battery not, because the battery was "destroy".

Regards and thanks for help
