I have one opened here.

The main bios is a Winbond W25Q64FW (take care: W = 1.8V, don’t program it directly with a TL866CS or CH341A, you will kill it)

The EC bios next to the ITE IT8987e is a Winbond W25LQ80 (3.3V) and can be programmed without adapter.

 

I just have an issue… there are two board versions and I’m looking for the BIOS image of a board with a front marking 71P1R1 AP135 and a back marking that starts with AP12D

I have a bricked HI-13 in my hands. Unsoldered BIOS and EC eeprom and reflashed them with the V14 bios.

I needed to unsolder the W25Q64 because it’s didn’t got 1.8v on the VCC pin when on board. Once unsoldered and using a 1.8V line converter, I was able to program it.

Battery is around 8V. When pressing power button, EC bios gets 3.3v for 13-14s and 5v line is also ok. Still no 1.8V on main bios, thus probably CPU doesn’t get powered either. Black screen and no leds

Somebody a similar experience ?
