Need help with a A820-2936-B board. Came with no charging issue. Working fine on battery. Changed U7000 and now no green light and no fan spin. 3.3v and 5v rails missing. Where do I start..
0.033 is still bad.
But high enough to make injecting voltage useless.
Check the capacitors connected to 3V42_G3H power rail.
Pay atention to ones connected near audio codec.
There must be one under plastic foam, near BIL connecter; it fails many times.
Checked all capacitors near the audio codes. Nothing suspicious. I am a newbie and would appreciate if you can give me part numbers to check on the 3V42_G3H power rail.
Click 3V42_G3H in boardview and check all caps you find there.
On this board is no cap placed near the BIL connector, my error.
There are very sensitive IR cameras on the market.
Can help you to detect very small temperature differences.
You should inspect all components connected to 3V42_G3h power rail.
