The Thinkpad (and probably other IBM/Lenovo) laptops have software that set when to recharge. So, I could leave my battery in while it's plugged in. The battery will just sit until it's needed.
I have it set so it doesn't recharge until it drops to 79% and then it recharges to 97% and stops.
if i take the battery out of a t520 will the wireless card suffer or will performance of the computer slow down
Any particular type of bag I should store my laptop battery in?
