i messed up my bios . And tried to recovery . But i cant do it .
i tried P5WE0x64.fd , P5WE0.fd , BIOS.fd in USB stick but ineffective .
I did recovery many times but in this version of bios i cant do this.
1-)What can i do ?
2-)I have PackardBell TS11HR how can i reset my bios ? (cmos reset or bios recovery)

[daniel1919]

anyone tried this on acer 5750g ? does it work,will it brick my laptop ?

[McBride]

I locked BIOS fan speed low and high to 100% but i'm sure isn't working... you can check this by software...

About your problem Daniel, this mod is designed for 5750G, i think you'll problems with your laptop!
Pay attention only when you flash it, this is my suggest...
