Ok to remove built-in Lenovo laptop battery?
Sorry I'm not home and don't have access to my Lenovo's windows version number.
I have a Lenovo laptop that I bought a few years ago as a backup laptop. I've just been keeping it in storage, thinking my current laptop was going to see the end of its life soon. During that time, I noticed that the battery drains itself (even after just a few months), even though the computer is shut down (not in sleep mode).
This month, I checked it after 5 months. 5 months ago before storing it, I charged the battery up to 75%, and then shut it down. When I plugged in and turned it on after 5 months, the battery was at ZERO percent. Upon reading that lithium batteries become damaged that way, and are unsafe to use afterwards, I don't really feel safe storing it in my house--at least not the battery.
If it had an easily removable battery, then no problem. But this one is built-in, requiring removal of the laptop's bottom cover, and then several screws from a circuit board. What I'd like to know is whether or not I could remove this battery, and then be able to operate the laptop from AC only. My Dell computer works fine that way, but it's battery is removable by just sliding a switch on the bottom of the unit and popping the battery out. But I'm wondering if Lenovo manufactures their laptops with the battery "built-in" because the laptop somehow relies on the battery even when it's shut down. That would explain why its battery drains itself in storage.
