Laptop not turning on after pluggin in the charger

Whenever I plug in the charger, the laptop's power button's light automatically turns on & the fan starts running heavily & after 5 seconds, the power turns off & on again. The cycle keeps on repeating itself until I plug off the charger.

Hi @gojirafan ,

Check the output voltage of the charger, using a Voltmeter.

Here are the specs:

19.0 V dc @ 4.74 A – 90 W or 18.5 V dc @ 3.5 A - 65 W depending on what variant you have
