Hello. I have a problem with the Asus X550CC Rev 2.0. It works on the charger itself, but won't charge the battery. The diode is on, but unfortunately, despite the message that the battery is being charged, the charge indicator drops. Tested on two power supplies and two batteries. Unfortunately, I can't find a schematic for it. Has anyone had a similar case or has a piece of a schematic and could share their insights? Thank you in advance.
