Hello guys. I have a legion 5 17ach6h with Ryzen 7 5600h and RTX3060.
It was working perfectly fine but the cpu was overheating so i decided to replace thermal paste. I bought one from local hardware store and replcaed. it looked fine then the fan started to spin at the full speed after about 1 minute and then immediately shut off after 10 seconds. Then I though if i have done something wrong, so i cleaned up everything with IPA and put new thermal paste. but the issue was still there. After that, I came across [URL="https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/3309089-lenovo-legion-5-high-fan-spin-turns-off-after-34-seconds"]this...

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.

I can tell you the bios in post 5 is a working bios. I just had a Lenovo Legion 5 17ACH6H with the same board number. I discovered someone had previously removed the bios chip from the motherboard. I had a similar bios chip reprogrammed and soldered in. Computer is working fine right now.
