Hello, I was wondering if it's safe to keep a laptop battery plugged in to the laptop even if its dead or has enough juice for few minutes? Thanks.
Dead laptop battery - safe to keep it plugged into the laptop?

Your question is not quite clear. By "dead" do you mean a defective battery that no longer works and needs replacing, or do you mean a drained one that's still functional and just needs to be recharged?
There's also the question of the situation. If the battery is just drained and the laptop is going to be in storage for a long while (at least two weeks), then the battery is best recharged to at least half full and then stored separately (unplugged). If the battery is drained and you will not be using the laptop for a short while, say while in school, then there's no problem leaving the battery in and the laptop turned off (just make sure it's not in sleep mode).

The batter is defective and should be replaced. It makes no sense to keep it plugged in. I wouldn't recommend using the laptop with a defective battery in place. There's no benefit in storing it separately though, since it's already dead. If it were a good battery then it would have been safer to store it separately with at least half full charge in it.
