Battery issues causing hard shut down

I have an Acer Aspire E5-575G i5 8GB 256GB SSD GTX 950M with about six years lifetime. Recently it started to shut down when battery reached about 85% and not on charge. Nothing in the system logs - hard shut down. I thought it was just the battery being crap after 6 years so bought a new one and switched. But the same issue persists also with the new battery.

Any advice on how to troubleshoot this?

Re: Battery issues causing hard shut down

just thought to provide more input, I too ran into similar problem lately, I am on Asus K401u i5 12GB 512GB (256+256) GeForce 940M, 6 years old laptop, I noticed my laptop power off abruptly when the battery is below 60%, it happens random once it is below 60%. Same as OP, I had my battery replaced just recently, I hadn't had such a problem previously as I was able to get my batter level to fall to 0% without abrupt power-off, As far as I can tell, I noticed such behaviour in late February, not sure if it is the problem from kernel update or so, and have no idea how to troubleshoot.

Other information:
KDE plasma version: 5.24.2
Kernel version: 5.16.12-arch-1-1

edit:

I would try to rollback to an earlier kernel that was released in Jan 2022, however as my WiFi is broken and I use an external USB adapter to get WiFI connection, and such device (TP-Link TL-WN823N) is not supported out of the box and I had to install the driver rtl8192eu manually, and rolling back to earlier version causes the driver unable to be rebuilt because of the gcc version is newer after the last update, and downgrading the gcc version seemed like too much of a trouble for me. Therefore, even if rolling back would solve the random shutdown as the battery fall below certain threshold, it wouldn't be a solution for me as I can't have my WiFi working that way.

Re: Battery issues causing hard shut down

I would dearly like to see an answer to this problem.

I have exactly the same symptoms, on battery - random shutdown.

Acer Travelmate B115M

Common causes of a random shutdown are overheating and memory faults. The Acer is not overheating, and I have run memtest to check the memory. Nothing is logged on shutdown, so my only solution is to keep the Acer plugged in
