How to verify if battery is good
I'm trying to repair my Asus Memo pad HD7 (ME173X-1A013A) because when I turn on it, it shows battery red icon for 2 seconds and it turns off
Charger is good
- battery to life end
- dirty charging micro usb port
- problem to charge circuit
I tried to clean usb port but nothing.
I opened tablet and I disconnected battery cable for 10 minutes and I connect it again but nothing.
I tried to hold down both power and volume keys for 10 seconds but nothing.
How can I check if battery is good for example?
