As per title, when battery is connected or jack connected: keyboard light flashes once but cannot turn laptop on. Holding power button for 10 seconds then the KB backlight will flash again. Unknown history and signs of previous repair (jump wire from CMOS battery holder positive terminal to R2453, presume broken trace under it)
Thermal camera at board, 3 points warming up (not hot, just warm). CPU, BQ chip and ethernet controller. I guess this is OK??
- Ethernet chip I guess is powered for wake on lan functionality?
- BQ chip is driving input mosfets
- CPU warming...
