## Firmware Upgrade Manager
_Dell Latitude 5520_ seems to be supported by [fwupd](https://fwupd.org), as it is found in the [device list](https://fwupd.org/lvfs/devices/). Use `fwupdmgr` to perform updates.
## Other Stuff
Here I list a few useful things from other configs. As I don't fully understand the implications I didn't enable them.
- `services.throttled.enable`: a fix for Intel CPU throttling
- `boot.blacklistedKernelModules = [ "psmouse" ];`: "touchpad goes over i2c" (whatever that means)
- `boot.blacklistedKernelModules = [ "firewire_ohci" ];`: fix for SD card reader (from the [Arch Wiki](https://wiki.archlinux.org/title/Dell_Latitude_E5520))
- `boot.kernelParams = [ "mem_sleep_default=deep" ];`: Force S3 sleep mode to preserve battery during sleep
