Anyone have a list of changes that they've made to increase battery life? I've got about three hours (with 80% limit in BIOS, which I might get rid of), so I'm sure there's a lot that can be changed.

Okay, installed both. Are there any specific config entries I should be looking at in tlp.conf?

I think the most important ones are:

  • SATA_LINKPWR_ON_BAT (this had an issue where it corrupted data, but that was a few years ago so it should be fine)

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


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

Thank you so much! I've uncommented all of these.

It basically immediately caused my laptop to freeze up and I had to hard reboot it. I took the opportunity as it was coming up to remove the 80% limit in the BIOS, and then I commented everything I had uncommented. :/
