From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

[SOLVED] Setting up an alarm (lemmy.ml)

I have installed Linux Mint 22 in a DELL laptop with a buggy ACPI implementation (the kernel complains about it during boot). The laptop hangs if it goes to sleep (I tried various Linux distros/kernel-versions, the result is the same).

Because of that, I have disabled SLEEP in the firmware (latest version for that laptop btw). So basically, when you close the lid, nothing happens (it just locks the screen).

However, sometimes you might be in a hurry and you close the lid to do something else, and then you forget about it. The result would be for the battery to run dry, which eventually destroys the battery.

My question is: what would be the best way to setup an audible alarm if the battery reaches 20%?

I would first attempt to fix the problem by flashing the bios with the newest version. What you are describing sounds a lot like a common issue with how deep sleep works. Its on the manufacturer to fix it which Dell is typically pretty good about.

If that doesnt work for some reason you can get an applet that will shut down your pc when the battery gets too low for you. Theres a few that work just right click the panel and search for battery applets.
