Jep I will tell if I'll find anything. Just now no ideas. Nothing look bad in pcb:s but unfortunately I don't have much electronics fixing skills. And new/used mainboards are simply too pricy in ebay/aliexpress...

Thanks :-) . Tried bios #50 but unfortunately not better result. Still slowly blinking power led only wake up sign. Perhaps there is some other problem.......

Hi,

I tried both files from post #17 from this thread as they are. And tried both by copying section 75C000 - 75DFFF from my original bios dump to them. No help. Does it mean I have something other wrong than bios? Or I too having DMI corrupted? Attached my latest bios trial. My original is in post #42 [ATTACH]n3605054[/ATTACH]...

Thanks. Tried #17 file FSCN28WW.bin. I tried earlier without modifying - not worked. Now modified bin by copying DMI section 75C000 - 75DFFF according post #32. Still not working - powerlight flash 10 s frequency and no more. Any ideas?

Hi,

Lenovo Legion 5 15ARH05H won't start. Power button led is on and of about 10s frequency. Nothing more happens.

Tried to start by removing devices one by one but no help. No visible physical damages found in pcb:s. Bios battery voltage is only about 2,4V but I suppose it is not causing problems. I bought CH341A programmer and received it recently. Attached original BIOS dump done with NeoProgrammer V2.2.0.10. I tried also most bios.bins found in this thread without success. I didn't make any DMI or other modifications just...
