My computer says that its plugged in but not charging how do i fix that?

AnUSB cable can be plugged into a n USB charger. The charger has a USB port that the cable plugs into, it is usually compliant with most USB charging cables. If your charger has a fixed cable, i.e. for a single make, you cannot fit a USB charging cable.
Most computers now also have the charging facility even when the computer is switched off.

My Lenovo computer's charging pin is broken. How do fix ?

Batteries have electronics data that software has to get to properly charge it. Newer lithium batteries maybe different. But apparently, you have a work around for a lengthy use of the new battery.

The charging cord isn't the problem here. I've seen this a few times on laptops, and the fix isn't achievable by anyone other than an expert. The problem is the power socket that's soldered to the motherboard is loose (when you plug the charging cord into the computer, you're actually plugging it into the power socket attached to the motherboard). To fix it requires that socket to be re-soldered to the motherboard. I recommend consulting a professional computer repairman.

It seems like the battery is plugged in but it is not working.. Try to install the latest version of BIOS for your computer from the computer manufacturer website... If the issue is still not fixed please contact the computer manufacturer and change the battery.. The problem will be fixed

It sounds like your charging port is broken.

If the Acer is brand new then it is under warranty. Take it back to where you bought the Acer and get it fixed under warranty. if you attempt to fix it yourself you will most likely void your warranty.

You could try to plug it in the back of the computer instead of the front . . fixed the problem for me, it now charges properly.

I have same problem. Was told that port which we plug the AC adaptor into is either cracked, loose, or broken. Apparently it is not a simple fix. Must be taken to PC repair shop where you'll be charged about $200.

I noticed you were talking about over heating issues. Does the mouse issue happen when the computer is on for a period time?

I know with some laptops there is software for the "gadgets" on the mouse pad. If you have software related to it.. try reinstalling.

I am getting mixed thoughts of what you maybe talking about... please explain.
