Currently, I have a switch that does not turn on, no switch logo , no backlight ,The Motherboard shows HAC-CPU-20,
when I plug it to 5v power shows as below and stuck at 0.47A.
when I plug in the charger it shows 14.9v. and still show 0.49a as below:
I opened the housing and measured the components one by one, nothing obvious was found.
i soldered a 10k resistor between the battery connector as advised
short the switch power on and stuck at 0.2a, I removed the emmc chip and do the same process and the amp still show 0.2a.
then I assemble the parts together and connect to the PC, and short the right slider as pics.
RCM was detected and also injected successfully as below, backlight works but nothing shows on screen.
now I have no idea how to go on…
