Hi, @Anand
Since the laptop shuts off as soon as the charger is unplugged, the battery does not appear to be supplying power.
First, shut down the laptop completely. Disconnect the charger, then hold the power button for about 30–40 seconds. Reconnect the charger and turn the laptop back on.
Also, if possible, make sure you are using the original ASUS charger and try another wall outlet.
If it still does not charge, to help narrow down the issue:
- What is the exact ASUS laptop model?
- What battery percentage is shown, and does Windows say "Plugged in" or "Plugged in, not charging"?
- Does the charging/battery light on the laptop come on when the charger is connected?
