Lenovo power supply plug bang and burned?

I have had a Lenovo ideapad 330s laptop for 3 months. I just plugged the charger charger into the socket as always and there was suddenly a huge spark and electricity was completely gone. Fuses are also out.

after I turned everything back on, I checked the plug com charger. The plug is slightly burned. Burn mark on the plug. It should be clear that this is no longer usable. But now the question to the tech savvy

can I assume that the power supply is also defective or will I only have to replace the plug?

the charger was used as always and I'm now unsure if I need the whole part new or if maybe only the plug needs to be replaced. And how does that come about, since the part is less than 3 months old and otherwise caused no problems

or is there something wrong with the socket?

If the plug is scorched, it doesn't necessarily have anything to do with the socket.

I would measure the resistance of the charger lead with a measuring device.

Possibly. The charger has blown.

When switched on (plugged into the socket) with the consumer on the charger. A high peak current can occur.

First you have to understand what you are writing. The whole loading structure consists of several parts. At least that's how it is with my laptop. First there's a line https://www.biologa-gmbh.com/Installationstechnik/Flexible-Kabel/Kaltgeraeteleitung

and a power supply unit / charger into which the power cord is plugged. The short circuit can be due to the cable or the power pack. To do this, you should try the line without a network by measuring with an ohmmeter. Better still, take it back to the dealer.

If the laptop is about 3 months old, then you still have a guarantee.

Contact LENOVO, they actually have to replace the defective power supply completely, and since you still have a guarantee, it's completely free!

PS:

I guess the power supply is broken, cables or sockets break very rarely.

1. Short circuit in the power supply (very likely)

2. Wire loose in the socket (very unlikely)

3. Foreign body (piece of wire, …) with pinched when inserted, also very unlikely.

Take the power supply to the dealer if there's still a guarantee.

Short circuit on the primary side, but after 3 months you still have a guarantee for used goods, provided that it was a commercial seller. Describe the problem to the seller and have the new power supply delivered.
