    That is incorrect information. The only way to damage the battery, is if you drop it or throw it. Then the battery will become damaged.

    When the computer shuts off due to the battery being low, is that not Windows deciding the laptop needs to be shut off to prevent battery damage? I know within power settings and/or group policy you can make this not happen, or make it happen at 1% which may be damaging levels. Just a guess.

    Draining lithium-ion batteries that low, especially under heavy load, can make them overheat and certainly cause damage. At the very least it will drastically decrease the life of the battery. The layers making up the battery actually start to warp. The reason there are circuits to monitor voltage and current drain (load) then shut the laptop down if the load is outside limits.

    Here's a good article: Advantages & Limitations of the Lithium-ion Battery - Battery University

    Are you referring to draining to 1% or 10%

    If the former, that was my point.

    No. At least not with my Toshiba notebook and other notebooks I have used and seen. It is the notebook maker's battery monitor/utility that controls this, not Windows and it works in conjunction with the hardware as controlled by the BIOS.

    Remember, notebooks can run on Linux too.

    I was referring to the 1% you posted. No laptop I know of lets the battery drain to that level, the lowest mine allows is 5%. And yea, it is all a function of the hardware and BIOS, not a OS controlled function, except you can adjust the critical setting up but not down beyond a preset value.

My laptops performance drops drastically. Why does this happen? When my battery gets down to I think 9% or something like that, there's no point in even using the laptop since the performance drops so much.
