820-000165 not charge

[paky]

hi guis
I have this card that doesn't want to charge the battery. no green or orange LEDs. Where can I start?

You must get first the amber light on Magsafe, no other way to charge the battery.

Any history available?
Audio works good?
Did you try another LIO board/flex?
Inspect J9500 pins under microscope.

i tried with 2 magsafe but nothing. No led
With another battery it starts and works. With magsafe inserted I see the charge symbol but no led.

"Audio works good?"
Please respond to all questions...

Also test for activity at left USB port.

No audio and USB port not work

In this case, 3V42_G3H doesn't arrive to LIO board.
Bad LIO flex/board, or J9500 contacts.

"Inspect J9500 pins under microscope."
Take your time...
