It turns on and the current is about 0.34A without ram and around 0.41A with ram attach. almost all the coil have the required voltage except for the PL5901. I dont have schematic on this unit. I already tried to reflash it with other bios but im not sure if it is tested ok

I am facing the same issue. How did you flash the BIOS without booting the laptop?

You need a spi programmer like CH34A/RT8209F etc.

Thank you for this info.
I am facing the same issue. Assuming this to be a corrupt BIOS issue, where can i find the correct BIOS image ?

Thank you for your response. I checked the lenovo site; the downloadable BIOS image is an exe file. (https://pcsupport.lenovo.com/in/en/p...me=BIOS%2FUEFI)
How can i get the bin file to write to the chip directly ?

Hi, just tried to extract it from EXE, but all of my extractors has failed, seems that Lenovo once again used something proprietary...
