I recently dual-booted my Dell Inspiron 3511, which originally came with Windows 11, with Ubuntu 24.04. I prefer using Linux because of its performance and the fresh experience. However, I have a challenge: I switch my battery charging settings between 80% and 100% when on AC power, and the only way I've found to manage this is through Dell Power Manager on Windows. I could dedicate most of my SSD space to Ubuntu and keep just enough Windows to handle power management, but I hate using up around 60 GB for that. Is there any way to adjust the battery charging thresholds on Ubuntu without relying on Windows?

If you're using Kubuntu 25.04, you'll be pleased to know that there's already built-in functionality in the power manager to set battery charge limits. It's worth looking into that version if you want to streamline the process!
You might want to try using TLP or auto-cpufreq. These tools are designed to optimize power management on Linux, and they allow you to set up charge limits for your battery based on whether you're plugged in or running on battery.
I'll give those a shot and report back on how it goes!
Tried both TLP and auto-cpufreq, but they didn't work for my model. Looks like Dell has locked certain settings, so only their software can modify battery configurations, not even the BIOS lets you change it. It's frustrating knowing I can't access those features. Thanks for suggesting!
