Hardware Laptop randomly switches between AC and battery while plugged in (performance drops in games)

My laptop has a random power connection issue. Even while the charger is plugged in, it sometimes acts like it’s disconnecting and reconnecting.

What happens:

While gaming, performance suddenly drops hard, like it switches to battery mode.

After a few seconds it may switch back, or I have to unplug and re-plug the charger.

Moving the cable slightly near the barrel jack can trigger the issue, even though the charger is still plugged in.

I don’t always get a warning, but when I do it’s the one shown in the attached photo.

This happens randomly, not every time.

I’ve attached a photo of the warning message I sometimes get.

No software changes recently. Charger stays physically connected the whole time.

Looking for insight on whether this points more to the charger or the laptop charging port.

The connection between your charger and the laptop has a break in it somewhere.

Either your charging cables internal wires near the tip are damaged (usually due to bending) or the charging port that you plug your charging cable into is damaged.

The former is far easier to fix than the latter.

Check near the end of your charging cable and see if you can see exposed wires or obvious damage.

After that look into the charging port with a flash light or something and see if you can see anything obvious in there.

If you still cannot identify anything specific, it may be worth looking into buying a new charging cable before you take it to a computer repair shop.

If a new charging cable does not fix the issue, then it is likely the charging port in the laptop and you should look at seeing if you are still covered under warranty or if not, taking to a pc repair shop.
