Laptop fell and usb port is broken, laptop won't start up

by JackLukass Nov 7, 2018 6:00AM PST

Hello!

My laptop accidentaly fell off my bed (about 40-50cm) inside of my backpack. The laptop won't start up anymore, my school diagnosed this and said the motherboard has to be replaced due to this broken usb port. I have gotten some pictures and they said it would cost over €800. Is it possible to fix it on my own, I don't care if I can use the usb port or not.

my laptop is a Lenovo Legion Y520-15IKBN
here are the pictures:

Thanks!

The school said this.

My school said the broken piece of the usb-port/mortherboard is short-circuiting so it won't start up..
I'll head to a computer repair center in a few days and see what they say.

Here's a thing about USB.

USB "spec" supports full shorting across the 4 signals. So I don't know why any PC tech would say that.

Anyhow, removing the banged up port is an entry level tech job. Here's a video.

Removal is pretty easy.

actually, that's what I was going to suggest

Is the port crushed flat, causing the inner contacts to touch? Remove the battery, do not plug in power cord, and shove something none conduction into the port, maybe it will move the contacts away from each other, end the short.

I'll be sure to try this!

I'll try this as soon as I get my laptop back, thanks a bunch!
Returning it is not an option since it's bought through school.

I'd ask a repair shop for a second opinion.

My bet is the damage is beyond the port.

by r. proffitt Forum moderator Nov 7, 2018 9:08AM PST

The usual drop damage is all over the map but if all things appear to be fine I'm going to write that a tech or someone could remove the banged up port but my bet is that the real damage or failure is elsewhere and thus you are looking at a new motherboard.

But that's not a sure thing in dropped laptops. The LCD and other parts are now suspect.

Try removing the USB port and then see what happens. There are plenty of YouTubes on removing, replacing that part. It's not required for operation so no need to solder in a new one.

Fix it.

Remove the USB and then try w/o it being present. You stated you didn't it anyways. The school shop stated it was shorten. I view the simple r/r of the USB as a easy fix. However, flat out remove the USB port. You could possibility with deft care place it flat against the mtrbd. and test it. I offer that as some solder points behind the USB or hidden underneath could be shorten. That alone will cause confused boot-up or stop the process. As others have stated because since the USB port is so damaged it took a hit that *MAY* have damaged something else. Besides replacing the mtrbd., you could shop around like on eBay and get a replacement, same model, swap HDs or data(clone) and return as if nothing happened if that is possible. good luck
