    If i have a laptop in hibernate mode and were to remove to battery and power cord, would this damage my laptop?

    Reason why I ask this is because at home, I remove my battery and use the outlet as my power supply. Sometimes I move from room to room. I want to avoid the "sticking battery in, remove cable, replug cable, remove battery" procedure. Too cumbersome.

    I don't think it will hurt anything since it stores everything to your hard drive and then basically shuts down your laptop.

    My only question though is why don't you just leave your battery in?

    As Tim mentioned, its fine, basically the notebook is off, it just caches the current data onto your HD for quick boot ups.

    Battery left inside a laptop (with power cord plugged in) will tend to get hot - just like normal. I am trying to prolong the battery's life (capacity). high temperature will tend to degrade the chemicals in the Li-Ion cell thus the max capacity will go down from for example, 4 hours -> 2 hrs.

    It should not be charging if it is fully charged already so shouldn't be getting hot. Try to recalibrate your battery also.

    FYI, I used to take the battery out of my old laptop when I sat on the couch with it .... it improved the balance and took off a big chunk of wieght sitting on my arm.

    Like they said, a hibernation is basically just caching memory to disk before a complete shutdown. So, once your laptop's hibernating, you can do whatever you please with the power source without worrying about negative effects.

    And if your battery is getting hot once fully charged then there is something wrong. All properly designed recent notebooks stop charging the battery once it reaches 100% and don't start recharging until the battery has lost a few % of charge.
