Why do my laptop turn on but didn’t start

1. Check the power supply

Laptops

There are various things that can go wrong here. You might have plugged in a power supply from a different laptop. Just because the connector fits, doesn’t mean it’s the right one. Laptops require a specific voltage, and they don’t all use the same. And even if the voltage from the power supply is correct, it may not deliver enough amps to power your laptop and charge its battery.

Check that the power supply is indeed the correct one for your laptop and is outputting the right voltage and amps. Stickers or markings on both the power supply and laptop should confirm this.

If your laptop is relatively modern and charges over USB-C, make sure you’re connecting the charger to the right USB port. Some laptops are particularly picky about having the official charger, especially Huawei MateBooks, so not just any USB-C power supply will do.

If it’s the correct charger, next check the fuse in the plug. Use a screwdriver to remove the fuse and swap it for one that’s known to be good. If you have a spare power cable that will plug into your power supply, this is a much quicker way to test that it isn’t the fuse at fault.

Check over the wire itself, as power supplies can have a hard life, especially if you carry them everywhere. Weak points are at the ends where it joins the black brick and at the plug which connects to the laptop. If you can see the coloured wires inside the black outer protection, it could be time to buy a new power supply unit (PSU
