While I sincerely appreciate the user, I often find we in Linux/OSS/FOSS are complicating our lives. Anyone wanting decent batterylife please get some JasperLake or GeminiLake refresh notebooks. These are available in eBay or retail for $200 - $300. I have a Dell latitude 3190 (fanless/HD screen), and Acer Swift 314 (fanless/IPS/FHD), and Acer Aspire 317 (FHD - 17 inches) - has decent HDMI (but barrel charger) 2 X USB. Close to 1.3 kg. Battery life - seems at least 12 hours. Sure I usually ssh and work remote.
