That's exactly what mine showed when ASPM wasn't enabled. Before that I got at most about 9 hours doing nothing, after enabling it I got about 14 hours even doing light webbrowsing and such.
I made a Reddit post about it today, enabling it under Linux manually. Many people have been complaining about low battery life on the Elitebook 845 G10, and most people suspected missing ASPM support to be the culprit. The nice thing is, under Linux you can force it, even if the BIOS doesn't offer it. I'm still testing though, so it is pretty experimental. You can find instructions on what I did here, if you're interested: https://old.reddit.com/r/AMDLaptops/comments/16lz0oh/anyone_managed_to_get_pci_express_activestate/k4klnmg/ https://old.reddit.com/r/AMDLaptops/comments/16lz0oh/anyone_...
Apologies, it is a pretty long post.
e: And I don't know if this generalizes to G9 laptops
- bubblethink 3y agoThanks. I'll try this out. For my next purchase, I'm going to stick to an Intel Thinkpad. I still use my 10 year old T530, and I bought this to replace it, but I still find myself using the T530 most of the time.
- nicolaslem 3y agoThank you very much for that, my G9 hovers around 5 W idle which is not great. I will try these tweaks. Note that there is a GUI app called "Power Statistics" that shows the evolution of power consumption on battery quite well. It still uses data reported by the battery which is not super accurate but works well enough when looking at say an hour of data points.
- nicolaslem 3y agoUnfortunately no clear improvement for me after applying these tweaks.
