    Can't find the post now, but someone linked an HP guide to taking care of your battery, which said to take out the battery if the machine is going to be plugged in for two weeks or more in a row.

    Ah, wait, here it is (thanks, Google): http://h20239.www2.hp.com/techcenter/battery/Battery_max.htm

    I would think that a lithium-ion battery is a lithium-ion battery. It's not as if battery technology is proprietary.

    I don't have a UPS (Uninterruptible Power Supply) and therefore prefer to leave the battery in the notebook as protection against possible blackouts. I also modified the default settings in the Power Manager as follows:

    - Start the Power Manager.
    - Go to the Battery Information tab.
    - Click Battery Maintenance.
    - Select "Optimize for battery lifespan (automatically charge for me)" under "Charge thresholds".

    I have an X60s and don't know if you can find the same settings in the Lenovo 3000 Power Manager.

    I believe I was the one who posted the hp guide. Yes, the principle is the same. It's not about Thinpad or HP, it's about lithium-ion battery.

    from: http://h20239.www2.hp.com/techcenter/battery/Battery_max.htm
    "Remove the battery if the notebook will be plugged into AC power continuously (via a wall adapter or docking station) for more than 2 weeks."

    From what I understand from that guide and any lithium-ion guide, you should remove the battery ONLY IF the notebook is going to be directly plugged-in an AC power for a VERY LONG PERIOD, say, two weeks. I think that makes sense. So if you're working on the notebook plugged in an AC during the day then turn it off at night, you don't have to worry. Plus, as mentioned by Fred, the Thinkvantage Power Manager takes good care of your battery.

    If you plan on leaving the battey out for a month or more in storage, bring it down to 45-35% charge for least amount of wear while not in use.
