This happens to me too,
change the timing and start earlier just before backlight and stays short for less time.

Mec16 is difficult
many many tries

I tried to understand the image but it is too advanced for me... when I saw his video on YouTube bypass 2 minutes... where it seems that he uses a jumper by touching 2 points and breaks the bios key... I thought it could be done like this as the video... I don't know how to read schematics, I'm very new to that level...

1 wire to ground on one of the points following 1 or 128/127/126 of your choice
at startup as indicated in previous posts

EC : NPCE68AP
L14/L15 gen1 GL40-GL5A0 NM-C631

of course, check that the diagram matches




Who has now used this technique and is satisfied with it here ??
just to give some feedback

It took me a while to disassemble because the keyboard is somewhat difficult to remove... before trying anything I preferred to consult and thus have safe advice... am I going to connect the ground jumper to 128? for 3 seconds straight? or how should I do it? thank you master!

Connect your motherboard to an external screen or with the original LCD, being careful.
Uses a USB keyboard to make things easier and avoid communication problems with the KBC(Ec)
Prepare a ground wire.
When everything is ready.

You must put a wire on the ground and make a light contact (1 -2 seconds should be enough).
If too long, errors occur : Fan error, Bad data, Thermal sensor etc ... and power off

Wait the Logo or just after the backlight.
Short contact with pin 128 or 1, wait and release
and press F1 to enter setup

After clearing security with blank password
and clear security chip.
Simply restart with Ctrl Alt Del
And test now


Warning:
Do not short before full startup (backlight), nor during shutdown.
Follow this carefully, otherwise there is a risk of bricking or corrupted data.

I couldn't enter... I touched 1 and 128 and nothing... it stays on the logo and if it is before it stays dark... use the point on the USB side and where the screw goes, which are ground and points 128 and 1 and 127 and 126 I did it many times
