Re: hp spectre x360 dead - please help
Short update : I have taken all BQ24715 pin voltages with or without AC power.
The laptop is always off during these measurements :
So BQ24715 seems to working, still the battery is not charging when AC power is plugged... How can I check that PHASE / HIDRV / LODRV are properly working ?
