Old BIOS error what? same problem or other..Please, need bios file for:
X553MA PRINCIPAL BOARD REV 2,0
I tested 3 bios diferent and not work (Black screen and power consumption is 0.67 a). i tested all points (5v,3v,1.07,1.8v) and all is present. Another symphton is when plug ac adapter turn on automatically and the battery same problem.
Thanks a lot. I Mind thats bios problem.
So much information I think is not a BIOS problemHi! Have good day Vinafix
I have weird problem on X553MA REV 2.0
Firstly I ve checked all supply lines voltage and noise on oscilloscope.
Every single bios tryed
Every single ITE ROM tryed
Also I ve updated bios from asus with latest one
No liquid damage no component damage no bending no stuck ram slot pin nothing. Mainboard looks brand new
USB line impedances normal every peripheral working good.
When pc has no cpu activity on windows its completely frozen no mouse movement no hdd activity nothing.
But if you stress cpu it works fine no freezing
Ive search the net this problem due to Intel Bay Trail cpu C-States problem (CPU IDLE problem)
Also there is no solution on Intel forums.
Is there any way to disable CPU C-States from modified bios or hardware cpu control pins?
Or Is there any program to disable c states?
Any help needed urgent..
