    Laptop Battery, Does It Hurt the Battery to Use External AC Power?


    I haven't used my laptop much yet, only a little bit to set up some bookmarks, wallpaper, etc. Every time I use it, I plug it into the wall. I'm at home so it's not inconvenient, and I figured it would save on the battery life.

    Is it harmful to the battery to keep plugging in the laptop, instead of letting it run off the battery? It's a Lithium-ion battery and HP laptop. Thanks for any advice.

    :)

    Battery Backup For Laptop When Power Outage?

    A UPS has three main parts :
    - A rectifier to convert the AC into DC
    - A battery to store energy
    - A Inverter to convert the DC into AC

    Fist step: You need to find out what you want to power with the UPS.
    For example, you want to power a Laptop (50W) and a monitor (80W) so your UPS should be at least around 250W, that is a small UPS.

    Second step: For how long you need the UPS. For example, if you want it to last 8 hours, you will need at least 250W x 8h = 2000Wh.
    If the battery on the UPS is 12V, you need to attach a 2000/12 = 160Ah (two large car batteries).
    Once discharged it can take days to recharge as the built in rectifier is designed for a low capacity battery.

    New battery not charging


    I suggested uninstall, not re-install.

    There's an extended version of those instructions - the same idea, but some additional steps.
    Shut down hte machine
    Remove the battery - run on AC power only
    Device Manager > Batteries
    Uninstall Microsoft ACPI-Compliant Control Method Battery
    Shut down the machine

    Remove AC power
    Wait 1 minte
    Insert Battery
    Connect AC power
    Start the machine

    Microsoft ACPI-Compliant Control Method Battery should be reinstalled when the machine is booting

    But, the .3 volts might be significant - I agree with Kbird
