try this and update me...

I have laptop Lenovo IdeaPad 3 15ITL6 with Intel Core i3-1115G4. When I press the start button, LED light on the start button starts blinking 12 times, then stops and after some time starts blinking 12 times again. When it stops, all voltages are down.

The motherboard is HS460 HS560 HS760 NM-D471 Rev: 2.0
S/N: PF3Q0WTF

The motherboard is not mine, also there were corrosion on the board which I cleaned.

Methods of fixing like fully turning off the motherboard or starting only with adapter doesn't work. All testing were did only with adapter on.
...

Can someone help me program this bios

As I wrote this 16MB file and it did not work, now I notice that there is a fresh new BIOS uploaded on Lenovo site, but I am unable to extract both the firmwares.bin from that file using this tutorial here:

Can you help us out or tell how to do extraction of this new file here at this link?

Behaviour : connect charger it power on automatically ,reach 0.170 amp than down to 0.74 amp...no display.

pl 1100 = 3 vlalw present
pl 100 = 0.221 v without battery and when battery connected 7.8 volt
pl 6602 = 1.2 v
pl 6603 = 1.056v...

The laptop auto starts when plugged in and only briefly stay off when forced off with power button, all voltage rails come up, power led flashing constantly and cpu gets warm but no display. I think it might be bios problem.
