Hi
I have a Lenovo z710
I upgraded my Bios with a bricked Insyde Uefi Bios, I found on Internet for z710, to unlock futures
After several normal boots, to see it's working good
I enter yesterday, Bios, and only enabled,, overclocking and 3-4 other disabled futures
After i tried to boot, I listened a big noise from fan working at maximum, screen remains black,, after 1 minute, power closes, it starts again - closes again,,, I removed laptop external battery, power supply, i pressed power button 1 min for hard reset, to remove electricity from internal circuits
I opened the laptop bottom, removed CMOS battery, for 12 hours, put a coin
I removed and put again my ram, 2 sticks
I put again the CMOS battery, and power cord
Laptop starts immediatelly alone, same problem , screen black, fan working at maximum, big noise
I can't enter Bios with Novi button or Fn R or Fn F1 or Fn F2
How can, I reset Bios to factory presets, if it's not affected by CMOS battery,
Do I have to sort Bios EEPROM??
Any other way??
