Windows 10: Why isn't my laptop working without the charger plugged in?

I have a Dell inspiron 5406 2n1, and I'm having a problem with the charger.If I unplug the charger from the laptop it will instantly go black and turn off or it will say 'your battery is very low' even though it's been charging all night.I thought it could be storage problems and the batteries too worn out from how much it's working, but it can't be the problem as I've gotten rid of a lot of storage, so I'm quite confused!It's been fine up until a few days ago and I don't know what's triggered it, the laptop itself works completely fine but it's just when I unplug it, it stops.Thanks.

Printer isn´t working after latest update.

After the latest update from Windows, my Canon Pixma ip6600 printer isnt working. In Device Manager it shows up as working properly but when I go to print it isn´t listed as an option in any programs. Troubleshoot suggests it´s a USB 2 printer on a USB
3 port and that that´s the problem but that cant be since it worked fine before the update. I´ve tried to uninstall and plug it back in but that doesn´t work either.

 

Laptop thinks charger is plugged in, even when it isn't

I recently bought a used ThinkPad X200, and replaced the battery with a third party one because the original was dead. Now the laptop seems to think that the charger is always plugged in, even when it isn't. I'm not sure what exactly I can do here, Google searches only turn up "plugged in, not charging" results.

Are you using original charger or Generic one? - Sound like the charging sensors have been damage on the laptop
