    I somewhat planned to upgrade when Ampere arrived ...and moreso now, plus I don't feel like sinking any money into it.

    I always run plugged in, so I don't need a battery and I'd rather not dig through the machine to get to the battery.

    ...Can I just leave it safely as is?

    ...will resetting it do anything? [currently 100%]

    Just remove the bottom and take the battery out. There is no "digging" involved, it's literally right there to be unplugged and removed.

    I would not leave the failing battery plugged in there out of laziness.

    Either you know another way to get to the battery ...that I'd be really interested in knowing or your defiinition of "digging" is somewhat askew.

    Huh. Apparently I completely forgot that my old GT72 had an enclosed battery. That's so strange, I don't remember that at all but every one I find online shows it.

    Please accept my apologies.

    In that case, you would be fine with just unplugging it.

    Is the battery literally just not working anymore? Or is there a sensor issue?

    I don't know.

    The battery icon states that it is at 100%, plugged in and charging.

    I'm going to drain it tomorrow and see if something changes when I recharge. Then I'll just unplug the battery if I get the same issue. Unless you have more info to troubleshoot it as a sensor issue.

    Thanks for the help.

    Just unplug the battery, the battery connector is visible by just removing the bottom cover, leave the battery on the chassis, but unconnected.

    If you have had the system for less than a year then you can claim warranty for the defective battery.
    Otherwise, best to disconnect and remove the battery from the system as you don't want anything happen with it.

    It's been unplugged. [It's ~5 years old now]

    Wear level jumped down to ~55% [from ~75%] when I drained it and I realized the battery is really shot when it read 85% charged on the windows icon while HWmonitior had it at ~10% of the new capacity.

    I see. If you are using it as a desktop replacement then there's no need to replace the battery.

    Unplugging the battery causes the system to power throttle at 65% of its max normal AC capacity on the Skylake and newer laptops. It acts as if the battery is plugged in but below 30% charge.
    I have NO idea if this applies to haswell or previous versions.
