ASUS ExpertBook B9 (B9403, Core Ultra 7 155H)
Sub-1 kg with a 75 Wh battery for about 12 real hours and a UVC webcam that avoids the Intel IPU6 trap. Audio needs a Cirrus amp profile and you want kernel 6.8+. A genuinely portable Linux road machine if you tune the speakers.
Compiled from public sources and community data, not hands-on tested. What that means.
Best on ubuntu LTS. Confidence: high

ubuntu-lts: Meteor Lake (155H) needs kernel 6.8 or newer for the Arc iGPU, so Ubuntu 24.04 GA is the floor. This chassis uses a normal UVC webcam, not the IPU6 MIPI one, which is the reason it grades better than the Dell/XPS Intel machines. Audio routes through a Cirrus amp that wants a sof and UCM profile to not sound thin. s2idle is functional but the magnesium chassis runs warm in standby until a recent kernel. Fingerprint enrols with fprintd after a quirk. RAM is soldered LPDDR5. ArchWiki: Intel Meteor Lake on Linux →
