I am on LA-A341P even though the image does not show it out, i shorted SCL & SDA

boot problem started after shunt so my assumption is the chip is fried, any sources for aquiring a new one ? i have 0 experience re-soldering but makes for a entertaining attempt atleast if a replacement chip is affordable

EDIT: tested both u2022 and u8 with multimeter and only things conductive are both GND so presumably both chips are fried for some reason

Re: Thinkpad Yoga LA-A341P BIOS

Many thanks - it works - I had to short pins 5 and 6 before the backlight came on, and then F1 let me in. On mine, it's a p24s08a

LA-A341P : 2x bios and 24rf08 + EC
LA-A342P : 2x bios and EC

the 24rf08 or p24s08a reads very well, this eprom is not locked
or bypass password with shunt on 24rf08 between scl and sda when backlight come and F1 to enter setup.
