Laptop Headphone jack got over-voltaged

[Laniakea]

My dad stepped on the cable that goes to my 2+1 speakers and it backfired and broke something in my laptop, now the left side is so much quiter, tried it with headphones too. My laptop model is Acer Nitro AN515-44. Is there any way to fix it easily, my university is starting 2 days from now and I cannot give it up unfortunately, thanks.

It's hard to tell what could have went wrong with the machine, regardless the repairs would require soldering and potentially a new chip if you fried one on the board. I would personally suggest getting a USB to 3.5mm adapter or a USB Type C to 3.5mm since you might not be using the USB C on your laptop and using that, at least for now.

Your speakers can't backfeed to your laptop, they're just not wired up in a way where that's possible. The most likely explanation is your headphone jack has been physically damaged. It may be possible to pull out the board and bend the internal contacts back into place, or reflow the solder on the connections if those were damaged.

Thank you Just out of curiosity, now that I won't be using my headphone jack anymore, can overvolting it again cause any bigger problems? Cause I have nothing to lose headphone-jack-wise, I'm curious if it can fix it.

Oh, so you mean physical like bending cables and resoldering things level physical right? I can do that, but it will void the warranty right?

Pretty much, there could be internal damage in the headphone jack, or damage to its connection to the motherboard. The jack might be able to be repaired, and replacing it would almost certainly fix it, but it's definitely going to void the warranty.

 

I'd suggest just getting some sort of USB audio device, it will likely be much easier.

I'd suggest not trying to electrically damage your laptop. I think it's probably unlikely to break anything farther back in the chain than the DAC, but I'd avoid taking that risk.
