CMOS reset & Recovery Procedure :


  1. Disconnect the system from external power source, remove main battery on a laptop.
  2. Remove the computer cover and locate the CMOS coin cell battery
  3. Disconnect the coin cell battery
  4. Press the power button for at least 10 seconds to drain all residual power from the system
  5. Re-connect the coin cell battery
  6. Assemble the unit and verify functionality
  7. Of course, set date and time, etc... and option you need
  8. i repeat : certain bios option can hang at boot, or do a blackscreen. (need to re-do the cmos reset)

IF and ONLY this steps not work, Go for bios recovery procedure, here it is :

1. Download the file attached with this post
2. Format an Usb key (if this one have a led, it's convenient to see the process during recovery) in FAT32 format without any file (no boot,etc...)
3. Unzip the file on the Usb key without changing the name, it's very important !
4. Remove the battery AND Unplug the AC adapter
5. Plug the USB key on your laptop
5. Hold the "END" key and plug the AC adapter
6. The computer start by itself and normally, must read the usb key (this is why a led on usb is cool)
7. The computer ask if he can flash the bios (allow it, but i suppose you're not mad,lol)
8. Normally at the end, the computer restart and you stop to hate me 😅

Windows 10 :

Working fine, but when it goes to sleep mode, sometimes when you wake up, you can have a beautiful BSOD with the famous : PAGE_FAULT_IN_NONPAGED_AREA

i search a lot and found who causing this :

Go to the Bios. Got to "Advanced" > "ACPI Settings" and set the "Enable ACPI Auto Configuration" to ENABLED.

Voilà :O)
