Swift Laptop Stuck at 99% when not charging

For background, I was away from my laptop for a week and when I came back I put it on charge like usual because the battery was drained. Since then, that being about 20 hours ago, my laptop has been stuck at 99%. Apparently, it went from 100% to 99% and then never dropped lower than that. I have not plugged it in since. No crashes or randomly turning off yet (mostly because I've been too worried to use it) but I don't know what this could mean and whether I should avoid using it/get it checked instead.

    Hi, it appears that the battery got somehow depleted, and the Smart chip may have disabled the battery for safety. To find out run a battery report, paste this in the command prompt: powercfg /batteryreport and open the report with your Edge browser, right click and select "Print to Microsoft PDF", attach the report to your reply, type @Puraw or use "Quote" when you reply so I will get an alert. You can also try to reset the battery, disconnect the adapter/charger and shut down, there is a small pinhole in the back of your laptop (with a battery sign), stick a pin in that hole till you feel it click (micro switch), keep pressing the pin for a few seconds. Plug in the adapter and try to charge.

    Hi, this should be the battery report:

    (editing to say I tried saving it as a pdf but trying to open that version myself results in an error, are there any alternatives?)

    Thank you for your help.

    Yes, the battery is not working anymore after last week (21 January 2025). Try to reset the battery with the pinhole in the back and if that won't work you can open the laptop as it is no longer under warranty (2021 model) to check the battery cable connection and reset the CMOS (see below). alternatively replace the 3-year-old battery.
    CMOS reset: Open the back of the laptop and disconnect the battery cable from the motherboard. Locate the CMOS module (with 2 twisted wires Red and Black under the right side of the battery) and remove the coin battery. Shorten the +/- terminals inside the CMOS capsule for 2 seconds with a bended paperclip and put the coin battery back with the + sign facing up, close the CMOS capsule. Next, press the Power Button on the keyboard for 10-15 seconds, after that reconnect the battery cable to the motherboard. Close the laptop, plug-in the adapter and see if the battery will charge normally.

    Likely you have both the battery in a state where it's internal data is corrupted and Windows in a state where it can't guess well as to the status of the battery. The CMOS reset won't affect either of those.

    To reset the battery, you want to first disconnect everything from the laptop, including the charger, make sure it's shut down, then press and hold that battery reset switch under the pinhole on the back for 15-30 second, then wait for 15-30 minutes to allow everything else to drain off. Then plug only the charger back in and wait for the full battery indication (blue LED) to come on. Go ahead then and reconnect anything that's not connected and turn it back on. That will get the battery to hopefully give correct data again.

    To calibrate Windows, run the system on battery until it shuts down due to the low battery settings. Connect the charger and wait again for the status to show a full charge, then turn it back on. Each time you do that Windows will be a little better at estimating time left and battery charge percentage.

    Neither of those require you to open it up… Which is a good thing. :)
