Liquid damage minimal - R5117, replaced.
Inspected board at 45x, no signs of further liquid damage.
PPBUS = 8.6
3V42 = 3V42
S5 rails = 3V3 and 5V
SMC_ADAPTER_EN = 3V3
PM_SLP_S5 = 0V
PM_SLP_S4 = 0V
No power cycles
Any thoughts please?
UPDATE: Replaced R1451 PM_DSW_PWRGD.
Now fan spins up for 10 seconds and then off. Connected a fully charged working battery to check for USB initialization but nothing. all_sys_pwrgd goes high while fan spins.
Also powers on from battery in the same way but no mouse LED. CPU does get hot.
