OK, fair enough.

For what it's worth -- my take on something like this would be:
"something is wrong here and I need to find out what it is and if I
can fix it". A problem with using a port is a problem, full stop. The
fact that it _manifests_ as mouse issues and the screen is OK doesn't
mean "don't worry about it" -- it means there's a problem to
investigate.

OK.

Can you give me the full exact model number? It's probably on a
sticker on the bottom of the case.

OK, well that's good, actually, inasmuch as it rules out one avenue to explore.

So you found it? :-)

What? No! Not at all. If it did, it would not be something I always
say, would it?

Firmware updates are, generally, something you must manually do
yourself, from Windows or booted off a USB key or something.

Even in Windows, where you have a supported tool, and a program to
check, and you run the check, it's not automatic. e.g. my own Thinkpad
X220, which I recently discovered to my great surprise actually has
UEFI, and dual-boots the latest Win10, and has the Lenovo System
Checker (or whatever it's called) installed.

I only boot Windows once in a few months. Lots of updates then follow.
The Lenovo tool runs automatically and checks. It never found new
firmware.

But nonetheless, there _was_ newer firmware and a couple of months ago
I had to download it myself and install it myself.

(It didn't change anything, but I like to keep current.)

Give me the _exact_ model number and find out what version your
firmware is -- go into it and look for an "about" screen or version
number -- and  I will find the current one and tell you if you need to
update.
