What exactly is a CMOS battery?
It's a coin-cell battery. Traditionally it was used to keep the memory that stores the bios-settings and the real-time-clock powered when the PC was turned off.
By now the bios settings are stored ona different kind of memory, so it doesn't need power when turned off.
But the rtc still needs power when the laptop is off as well as other stuff (for example the circuitry that makes the power-button work)
In the framework it's also rechargeable, so you can't just swap it for a cheap one from the store once it runs out.
I mean that seems like a better way to do it, I'm assuming these things last for years by the fact I've never had to replace one or even know about it
How is it only charging when plugged in an issue if it lasts longer than the laptop's own battery
I guess if you don't use it for long enough it depletes while powered off
The battery lasts about a mont in that laptop and gets worse quickly over time when not regularly charged.
I'm not sure if the short runtime is caused by the design-decision of using a rechargeable battery or a big power-draw from it.
For me this is also the first laptop that ever had an issue like that. Even my decade old thinkpad is still on its first CMOS battery.
