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.

My current charger is broken, but I found another charger which kind of fits, but im suspicious if it will harm my laptops battery in the long run, what commands can I run or what can I look at to see if a new type of charger is harming a laptops battery? as this isnt usb-c or anything really official.

And, anybody who has played in RaspberryPi 5 land will probably know: there's different voltages delivered in USB-C and each has its own amperage limit in a given charger, so the wattage rating of the charger doesn't tell the whole story. Like a PC internal supply you need to ask: what's the amperage capacity at 5V, 9V, 15V, 20V ? A "90W" USB-C charger might only deliver 100mA at 5V and 9V with most of the "juice" delivered at 15 and/or 20V - and what voltages is your laptop configured to be able to consume for battery charging?

It usually works out simply enough for most consumers, but not always...
