How to repair this broken cable?

I'd like to fix that, otherwise my laptop will drown… If you put it in a certain position, the electricity will come through, but not otherwise. Who knows about it?

Buy new cable.

If you tinker with it yourself there's a risk of fire.

You need a new cable.
In the meantime, you can rigidly connect the old cable like a broken leg (with insulating tape or firm adhesive tape, possibly with "rail", any stick you wrap with the cable so that it stays in the desired position.
Only until you have a cable that is secure.

Buy a new connector, the connection line is broken right behind the bend protection sleeve (a typical problem).

If you are in a good mood, you could still remove the protection a little to make room for soldering. But you have to have a lot of experience and / or sensitivity.

Buying a new plug would be the order of the day, but it must be able to withstand the charging current, otherwise it will fail in the long run.

Laptop and water are not compatible. Now I don't see any water damage on the plug. The cable on the connector housing is defective.

You could try cutting away the case enough to get to the broken spot.

I would not recommend that, as there's a noise of over 3 amperes and more over the line. It doesn't last long.

As I said: Only until he has a new cable. Better than what he's doing now.

Most of the time, the cables are firmly connected to the charger, so you have to patch them well.

When you break, you only catch part of the strands of one wire. It is important to avoid that.

Where was there some water damage 😅

Otherwise my laptop will drain

There's rather no fire risk…

On the one hand there's only 19V on it, so that no extreme sparks etc. Would be expected, on the other hand, a fuse in the power supply responds to a short circuit. That is (without knowledge of soldering) then in the Ar… But it will not burn.

Oh come on

Buy a new connector. Cut the old one about 5 cm behind the break point and solder the new one on. All other attempts to repair are murks.

Choose the right size

Casual sayings generally do not lead to a better understanding of a question, especially since you wrote something about the booze!

Repairing such a cable break is usually No problem… However, you have to do it professionally and also know what you are doing because there's not much cable available. See if there's a Repair Cafe in your area soon… There you will be helped quickly and quickly. The cable is tweaked to different lengths, the kink protection is slightly removed and re-soldered. Shrink tube over it and you're done!

For the future, you should note that cables should always be treated appropriately in such places that kinking should be avoided.

I'm not the questioner.

But yes, of course you're right.
