"Instructions for use"
Remove all battery and CMOS battery
press F1 to enter setup: password 1234
wait 20sec or more.
Enter any ID to hardware Id.
Press 2x space bar when asked.
Turn off the computer.
and restore your original bios .
Enjoy.
If 2x 5beep, it's normal.
I didn't do checksum but it must light up anyway.
Wait minimum 30sec before screen logo light on. Must turn on/off several times by itself.

Good morning, follow the steps as the instructions say, the laptop turns on and off after about 10 seconds and it doesn't turn back on, it stays off... I really need to patch the bios that I attached in the first message, with that if it turns on at once

Friend, it doesn't work, the laptop only turns off once and it stays off, I'll show you a video, instead with the one I'll give you if it turns on...

I do not understand, because it does not give an image... If it is the same bios, only patched. are you sure it's mine? because it has a different name
sometimes problem happen when the file is patched
the name of file does not matter !
i patched it and just named it PATCH !
