Hello, I was wondering if anyone could help. My Asus Zenbook will only turn on and stay on when plugged in, if it becomes unplugged it dies instantly, the battery is also saying "255% charged (plugged in)". I thought maybe my battery had become completely discharged but have replaced that and still having the same issues. Any ideas what's wrong? I'm completely stumped

First port of call would be to take a look at the battery driver.

Open Device Manager and tab to Batteries. Delete the driver from your machine and delete the software. that has been installed with it.

Now in Device Manager click Action and then click Scan for hardware changes

Just tried that and it didn’t change anything
As I said it's the first port of call and therefor a step in the process.

We can assume the charger is working as it runs the machine.

What replacement battery have you bought and from where? Model number and manufacturer would be good.

Here's another process to try
  1. Shut down your laptop.
  2. Remove any peripheral devices connecting to your laptop
  3. Unplug the AC adapter charger from your laptop
  4. Remove the battery from your laptop
  5. Press and hold down the power button for 60 seconds, then release.
  6. Re-plug the AC adapter/power charger
  7. Power on your laptop as normal

Here's another process to check out


ASUS provides a feature “ASUS Battery Health Charging”, and it pops up automatically in the very beginning after your OS is installed. It offers three options for you to choose for your battery health:

  • Full Capacity Mode: Your battery is charged to its full capacity.
  • Balanced Mode: Your battery stops charging when the power is above 80% and re-charges when the power is below 78%.
  • Maximum Lifespan Mode: Your battery stops charging when the power is above 60% and re-charges when the power is below 58%.
So if your ASUS laptop is in Balanced Mode or Maximum Lifespan Mode, you might see the issue you are facing

1) Go to Taskbar > Show hidden icons at the bottom right corner.


2) Click the battery health charging mode icon.


3) In the popup window, select the first option: Full Capacity Mode. Then click OK to save.


4) Restart your laptop.
