hello everyone,i need your help 🙏,i need bios for this laptop Lenovo Thinkpad E15 FE4A0/FE5A0 NM-C421 20RD to use it with ic programer thank you in advance.

Hi at all. My thinkpad is dead yesterday.
After open the bottom board, i see PQ1101 go to burn after powerup.
Probably is shorted? On the schematic is a n channel mosfet, marked as AONR32340C.



Hope someone help.

Thanks,

Need help to fix my son's laptop.

I changed the USB C port, still no charging. checked U5901/RTS5455, pin 25 has 5V, pin 26 has 3.3V. Not sure where to check next.

If any one can tell where I should check next, it'll be much appreciated. Thanks.
