I got my Acer Swift Go 16 two weeks ago. I use it as a desktop connected to an external monitor and have the power usb-c cable always plugged in. I have turned on smart charging so that it's topped out at 80%. It'd been working fine… until this morning.
I was streaming some tv show for about 2 hours, then out of the blue I got this "battery low" notification. At this time, there's only 5% battery left. The battery icon still showed that it's plugged in, and the amber "charging light" on the side of the laptop was illuminating. A few minutes later, the computer shut down on its own. I turned it back on right away, and the battery is down to 1%, and it shut down on its own once again. The "charging light" was still illuminated.
I left the laptop alone for about 20 minutes, and then turned it back on again. Now the battery was back at 14%. From this point on, the laptop seemed to have back to its normal self. The battery continued to charge and stopped the charging at 80%.
I did a sleep study (powercfg /sleepstudy), and the report showed two weird entry. One was last night after I put the laptop in hibernate, it started to charge the battery over 80%. By the time I woke up the laptop, it's at 100%. Then it started draining the battery for the following two hours, resulting in the shutdowns.
The laptop is up for two hours now and the battery sits at 80% just like before.
My question: Is this charging to 100% and draining to 0% a part of the "smart charging" protocol? Or is it an indication that there's something wrong with my battery, or something else? Thanks.
