I've noticed that my Lenovo laptop shuts down as soon as I unplug the charger, even though it shows that the battery is charged. Usually, when a laptop is charging, the battery percentage goes up, but mine doesn't seem to be doing that. I've tried restarting it multiple times, but everything is running really slow and unresponsive. I've seen suggestions online about hard resetting it or even removing the battery, but I'm not very tech-savvy and I'm not sure what to do next.

It sounds like your battery might be dead. When you take the case off, check the battery for any bulging or damage—if it looks like a 'spicy pillow,' it's probably time for a new one! Be cautious, though, as a faulty battery can be a fire hazard.
I had a similar experience a few years back. I ended up buying a replacement battery from a UK warehouse, but it was in worse condition than the original! If you can, I'd suggest considering a new laptop instead.
One of the battery cells might be faulty and causing the problem. I recommend replacing the battery entirely. Does that help clarify things?
Your issue could stem from either the battery or something on the motherboard related to the charging circuit. If the battery was working fine before (no odd behavior like it disappearing from the battery settings), I'd suggest taking it to a repair shop for a proper diagnostic.
