Re: Lenovo ideapad 5 14alc05
Thank you for advice.
Will look at the board more carefully.
Power pin of bios has only 0.028 of 1.8, and look like almost shorted to the ground.
Wiil try to find power supply for 1.8 at board to check it health.
Thank again for manual!...

Re: Lenovo ideapad 5 14alc05
Yes my chip is 1,8v device, and i have the adapter for it.
The indutor was hot before i have tried to read the BIOS. So i'm sure, that it was broken before me.
Last two night before dead, lenovo drain all battery till night. Short circuit progressed to total....Last edited by Frostya; 09-24-2023, 08:57 AM.Leave a comment:

Re: Lenovo ideapad 5 14alc05
Sorry, guys.
Board has short circuit in 1,8 power line.
It's not a bios.
One of the indutor became too hot. It has strange voltage: 0,846 from one side and 0,766 from other.
Heat pipes hot too.Last edited by Frostya; 09-24-2023, 04:10 AM.Leave a comment:
