"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.

verifique las instrucciones cuidadosamente
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...

That is to say that I need the programmer for ec? or is that installed in the same bios? since I don't have an EC programmer, only a CH341A bios programmer
i checked more and realized that the password is not stored on bios

you need to program EC to remove password
