My all time favorite laptop was the 1994 Apple PowerBook DUO 280 with active greyscale screen. These screens actually looked the best in direct sunlight with no backlighting The battery life was listed as 2-4 hours. Normally it was under 3 hours. However, with no backlighting and booting a stripped down Mac OS and apps off a RAM disk, I could get close to 6 hours in BBedit or WriteNow. I would spin up the HD to save data and turn it off again. https://everymac.com/systems/apple/powerbook_duo/specs/mac_powerbook_duo280.html https://everymac.com/systems/apple/powerbook_duo/specs/mac_p...
