...ever heard of a cigarette lighter plug? Maybe Zaio will
hop on it, so their walkers can stay out a week at a time.
Next Zaio ad...."24/7, Infared Photos, We Never Sleep, We're Not Like Other Lazy Appraisers".
You can extend your laptop battery life with plenty of things such as Notebook Hardware Control (NHC). I have my 1.6 Pentium M pin modded to run at 2.13. It runs cool and I have it undervolted and dynamic switching enabled. It now shows my remaining time go up to 3 1/2 hours which is about an hour more than before.
Either way, I can't drive and type at the same time and hate using things such as PDA's in the field.
