Yes, generally, the laptop can be used separately to the charger. That is why they are portable
Why doesn't your laptop charge even though it's plugged in
cause it hates u
If your laptop is turned on and it looks like it's plugged in, the batter could possibly be dead or the connection from the outlet to the computer has a problem.
Computers don't have batteries so I'm assuming you're talking about a laptop. Laptops with their battery SHOULD work when its plugged in. Some laptops can even work WITHOUT the battery but still plugged in. However, if your battery has a critical flaw (dead short) then even with it plugged in, it won't work. I suggest you try the laptop with the battery removed. If it works, that is the problem, otherwise, your laptop has other problems.
What I do is take the battery out and put it back in. But make sure you don't have the charger plugged in or it could damage if not break your laptop.
It doesn't matter either way. I personally keep mine plugged in when I don't need to bring it anywhere. When you have it plugged, make sure the whole charger is unplugged from the outlet so it isn't still sucking up energy even when the laptop isn't plugged in.
not really. if you take out the battery when plugged in you could short circuit the laptop. trust me i know.
Yes, you can. I have mine plugged into my laptop.
You can't
Your laptop will use full audio quality if you turn up the volume 100% and change your settings to high volume.
no
as long as you have your laptop plugged in, you can use it.
