Loose USB port fix solution

[bass1175]

So I noticed any device will connect disconnect if I move my USB the slightest bit. WAs very annoying as I had to be very careful when transferring large files from externals to the machine, any movement would halt the transfer.

Called up Warranty in Ga and they were ready to send out a new Motherboard with a tech for onsite repair.

Investigating a bit further, and comparing the inside of the USB port with another T420 machine I own. I noticed the pins were pretty flat to the top of the USB wall.

I disconnected the battery, power supply, and pressed the power button for 30 seconds to release any stored charge and used an iphone scrrew driver to carefully pry down the 4 Gold prongs. Problem was solved and cancelled the scheduled repair.

If you pry too far out and the prong comes out under the top wall, no worries just slowly push back in.

There are also two prongs on the bottom that only help seat the plug, you can pry those up as well, but the main issue is in the top prongs.

Its a guaranteed fix for those with similar issues connecting and disconnecting with simple movement. Might be great for those out of warranty or dont want to switch out a whole MB. Noticed other models suffered this more then the T series, hope it helps someone, Cheers.
