According to https://community.acer.com/en/t5/Android-Tablets/Iconia-tab-10-A3-A20-won-t-charge/m-p/513098/highlight/true,
Hello, my tablet was working fine for a year and suddenly won't charge up.
When plugged in while turned off, the screen will power up, showing the empty battery icon then another icon with a low battery and a power plug.
Then the screen will turn off and start over alternating both icons and so on.
I am going to upload the two screens the OP was talking about:
"Empty battery icon" // "Icon with a low battery and a power plug"
Do the two screens have different meanings? If yes, then what do they mean? Are they "charging" and "connect to power"?
