Hi Guys!
I have a 820-00165 that has some strange failure.
Runs with charger fine, charges battery.
The problem comes in without charger:
If battery is attached can be started with power button until it boots into OS.
After shutting down form os I have to press power button for 10secs to turn it on again. (Power pad does the same, so not a keyboard related problem!)
If battery is removed then reconnected the board can be turned on with a short press like it should. (Until it goes to OS)
If charger is connected the power button is always working normally.
The machine can wake up from battery. However it seems to be it can not go to deep sleep, battery drains fast (goes flat in few days) if I just close the lid. Nothing was connected to the machine while it was in standby.
Tried another battery, different SSD... Now the board is on my desk, no display, no ssd is installed, OS is loaded from an external disk via USB.
As per an information found on other forum this "long press start" disables the SMC's AMON/BMON sensing function. I found no faulty parts yet.
U7100 looks fine current sensing resistors are intact and values are good.
Any idea? I am totally stuck!
Thanks in advance!
