  • Depends entirely on what you’re using the device for and how (if at all) you utilize networked (NAS, cloud, etc) or external storage. For me personally 256gb would be way more than needed, since I have nothing that would take large amounts of storage on local device.

    I guess that might be true but for me just installing all the random proprietary crap like matlab takes up a lot of my storage (even more if you need multiple versions), so for using laptops in education I really doubt that 250gb is comfortably enough. I’d honestly rather pay the extra $15 than constantly worry about running out of storage.

    1x 16gb would allow cheaper upgrade to 32gb later if that’s something OP is concerned about.

    I don’t really like this argument because by the time they’d be upgrading ram the price of ram (of that speed/spec) would probably have depreciated a lot and it would be just cheaper to buy it in the future. It also kinda limits you to staying on that generation/speed of ram which is bad.










  • I think the most important ones are:

    • CPU_SCALING_GOVERNOR_ON_BAT
    • CPU_ENERGY_PERF_POLICY_ON_BAT
    • CPU_BOOST_ON_BAT
    • CPU_HWP_DYN_BOOST_ON_BAT
    • SATA_LINKPWR_ON_BAT (this had an issue where it corrupted data, but that was a few years ago so it should be fine)
    • AHCI__RUNTIME_PM_ON_BAT
    • WIFI_PWR_ON_BAT
    • PCIE_ASPM_ON_BAT
    • RUNTIME_PM_ON_BAT

    (I haven’t used these myself because I don’t have a radeon card, but it should improve battery life for you):

    • RADEON_DPM_PERF_LEVEL_ON_BAT
    • RADEON_DPM_STATE_ON_BAT

    I had to set USB_AUTOSUSPEND=0 because otherwise my usb devices kept turning off, but you might not need this.


  • have you done the TLP stuff?

    first make sure you don’t have power profiles daemon because this conflicts with tlp

    you can turn it off with

    sudo systemctl stop power-profiles-daemon.service
    sudo systemctl mask power-profiles-daemon.service
    

    install tlp with

    sudo apt install tlp
    sudo systemctl enable tlp
    

    and edit the config at /etc/tlp.conf to optimise your battery

    the instructions are in the file iirc

    basically set your CPU settings (I use powersave on my intel non-framework), and maybe have a look at the radeon graphics things (I don’t have an amd system so I can’t say much about this)

    and refresh your config with

    sudo tlp start

    if you also get powertop (sudo apt install powertop) you can monitor your power consumption in that. (sudo powertop)

    If you can’t be bothered with this, I think you can also just install power profiles daemon but I like tlp better because it gives you much finer control over your system
