Hi, I have my laptop plugged in to the AC most of the time, My battery is also in and charged fully...will it hurt the battery If I continue to keep my AC adapter plugged in with the battery still in. Should I take the battery out if its fully charged?

I have a TOshiba p15 S470

Its always a good idea to give a laptop battery a bit of work do from time to time. If you leave it in a fully charged state for a prolonged period of time it will deteriorate. Batteries thrive on hard work.

Pull the mains plug out from time to time, about once a month should be enough, and let it drain the battery completely and re-charge. It will prolong the life of the battery. Leaving the battery in in the meantime wont do any harm. In fact some laptops wont work without a battery installed even with the mains plug plugged in.

Stuart gives good advice but I've found it to be hard to practice and I haven't noticed a prolonged battery life when I've tried to practice it.

I'm on my second battery since I got my laptop 3 years ago and by the time this one goes, I'll probably be ready for a new laptop.

hey i have a hp ze4400 and i have to have it connected to the electricty or it wont work , i thought the battery was completly dead so i took it out and pressed the battery reader and it sais the battery is full ! so i need someone to help me out to find a solution!!
