So a customer brought an asus gaming laptop to me with a damaged charge port. After inspecting the port I realized the ground pin was pushed back. Using my skill I managed to get the pin back into a position where it would temporarily power the system while we waited for a new charge port.
System worked fine, had no issues other than it wouldn't charge. The new port came in, it was clean in clean out solder job. After soldering I check to make sure there were no shorts.
Now after reassembling the entire laptop and plugging it in I have found the strangest issue I have come across.
I have 19.5 at the battery charge circuit and going into the battery. But it doesn't charge. I tried a different charger. I tried putting the battery in a like system and testing the battery, that too was good
So now after testing I turn on the system not only does it have power, but the battery seems like it may be charging however. No lightning bolt icon over battery to indicate it's plugged in, no animation to indicate it's charging.
All I get is a battery icon that shows the battery is dead, yet it's been running on battery power for over 45 minutes now, with no signs of running low.
Obviously I cannot send this back to the customer even though it appears it's working. There no indicators. I'm at a loss for what or where to inspect next. I've used my DMM on every circuit pertaining to the charge circuit, everything tests fine.
Clearly the system is not fine.
Any ideas?
