I have an Asus X540LJ laptop. I recently changed the battery: it is properly detected, and is charging if the AC cable is plugged in.
But my problem is: if the laptop is running, by unplugging the AC cable the laptop immediately shuts down; as well as the battery led is blinking orange!
I did a battery reset (by following steps on https://www.drivereasy.com/knowledge/asus-laptop-plugged-in-not-charging-solved/), the problem still persists.
If the AC cable is not plugged in, then I can't power on the laptop (by plugging AC cable in, power-on is possible).
What should I do? The battery is recognised, the driver is recent, the battery reset was done. But still no battery-mode, and the led is blinking orange.
