I applied the file in post 5 and am getting the same results. No changes. I wonder if the EC chip I installed is also corrupted. All voltages are present. I can see both the cpu and gpu heating up under IR camera.

It was a chip I purchased online. The chip was removed from another similar computer model. I soldered it onto the motherboard.

Hello, I have this Lenovo Legion 5 17ACH6H computer with no power. I replaced the EC chip and the computer starts now but no post. When I push the power button, the keyboard lights up briefly, both fans begin to spin, the cpu and gpu get considerably warm but no post.
I suspect corrupted bios. Could someone, please take a look at the bin file and fix it? Thank you.

Hello, I finally found some time to deal with the laptop I mentioned in post 5. I know it's been awhile.
So, I have this Thinkpad T15 Gen 2 with booting issues. Upon start, the keyboard lights up briefly, the fan spins and the CPU gets really warm but no post. Computer draws close to 1Amp. I suspect corrupted bios.
This model has 2 bios chips located around the memory slot: one below it and one to the right of it.
I am providing both files.
Can someone take a look at both bin files and have them fixed? I do not know which bios chip is needed, so I have...

What I am saying you both came up with a bin file that was identical to one another. Regardless of that, the file worked as intended and I am thanking you.

Legion 5 15ARH7H bios request
I have this Legion 5 15ARH7H gaming computer which I suspect has corrupted bios. Upon start, the keyboard lights up, the fans start kicking and both the cpu and the gpu get warm. Subsequently, I get a screen backlight. However, no video to the screen or thru HDMI port.
Could someone, please fix the bios on this computer?

Yes, computer is starting now without any errors. I just had to use BCU to turn off manufacturing mode and everything is fine. Thank you.

I looked and it appears to be a resistor measuring 235K Ohms across.

Hello, I have this Elitebook 855 G8 computer with admin password. I removed the password that is located around 0x37000 area but now on every boot I am getting "HP Endpoint Security Controller Problem" error.
If I recall correctly, the issue is with the main bios chip. So, I am including both original bin files.

Lenovo Yoga C740-14IML charging issue
I am working on Lenovo Yoga C740-14IML that was missing 5V rail. I had that fixed and the computer is running. However, computer is not charging, though the orange light comes on whenever I plug in the charger.
It runs off the charger with battery detached. This is fine.
It runs off the battery when the charger is unplugged. This is fine, too.
However, with both the charger and the battery plugged in, the charger's current immediately plunges to 0 and the computer is completely running off the battery.
I had the BQ chip replaced with the same results. The...

I have tried 3 or 4 different wifi cards. None of these cards show up in Device Manager, even under "Hidden" menu. I know these cards are all good.

I applied the file in post 2 and the wifi device is still not showing in Device Manager. So, it seems the wifi circuit has an issue. I am just going to get an external usb wifi adapter. Thank you.
