    Seeing as this is the UL forum.
    Depends on whether you take it and if you turn it on.


    In all seriousness 2-6 hours seems to be what the range of new batteries are. Just running the screen eats a lot of power. Look at the settings and adjust the sceen brightness down and make sure the processer is not doing unnecessary background things. I am sure there are more but at home one is enough.

    Actually for a week or more on the trail I thought I could put a couple of small car batteries, (UL content) in one of those bag lady grocery carts.Maybe even rig a bicycle headlight generator to the wheels so it would charge as I pull it. (light weight generator, another UL reference)

    Inasmuch as this is the ultralight forum, with respect, I suggest, zero.

    At least two.

    Take a UMPC, or even the email device PocketMail.

    PocketMail is useful for trail journals. It is held near the earpiece of an analogue telehone, like most pay phones.

    Lightweight.

    Ok I looked this isn't the humor section, so I will try to answer this question.... You would have to carry a second Li battery designed for your laptop. The idea of carrying motorcycle or alarm batteries is very impractical because few laptops are 12 volt anymore. The Laptop needs a 12 volt to 125 volt inverter (100 watt or better) to run the charger/ power supply that was included with the laptop.

    Honest Connies Pocketmail or a Palm/ or a Phone with a qwerty keyboard with an extra MB chip in it is far more practical for trail journals.
    Dogs are excellent judges of character, this fact goes a long way toward explaining why some people don't like being around them.

    Consider a redundant system- pen and pad.

    PS- You would've gotten less flack from everyone if you hadn't put this in a UL hiker forum then suggested carrying a laptop and several car batteries.

    Indeed, the humor section would be more approperate.

    I meet one guy who was shipping his laptop mail drop to mail drop. Never meet anyone actually lugging one around. Even the new, little netbooks would be a bit much to carry. Besides the wieght, keeping if from getting wet or otherwise damaged would be difficult.

    I carry a PDA, about 8 oz with an AC charger and small solar panel to help keep it alive on longer streaches between towns. A smart phone (Iphone, Blackberry, MotoQ, etc) would do the same thing, but I don't need the phone.

    You know come to think of it, a desktop would work much better on the shelves inside all the shelters.
