laptop battery-life;how to extend?

Archived from groups: comp.sys.laptops (More info?)

Hi..

After fiing my laptop; i find the 2 hour battery limit rather irritating!

Toshiba make their batteries last up to 8 hours; is there any way i could
get a battery for my fujitsu-siemens laptop that would last more than 2
hours? Even 4 hours... I mean seriously, 2 hours is wayy too short; and if
you do tasks on it it just doesn't last 2 hours! It's soo frustrating!!

This amilo D7830 being my first laptop (PCWORLD one, advertised to buggary
in the papers and on the tv) i've probably lessons to learn; but still, i
was hoping i could buy a battery with a better life, but the internet seems
to prove i can't :(

Ah well...

    Xp home; i'm very experienced with pc's in general; but laptops are another
    story...a lot more can go wrong with them, and altough 2 hours sounds like a
    lot, when you see that battery-charge percentage going down very couple of
    minutes, it becomes quite disconserting; you don't know how long you've got
    left REALLY...

    But ah well, i'll know for when i buy a knew one in 2006...

    Thankies

    NO! WRONG!

    You do not have a laptop

    You had been tricked to purchase a pseudo "Laptop" with
    hot desktop CPU

    Look on the power usage, while the computer does nothing else
    than wait for an user action

    http://notebook.pege.org/benchmarks/warten-stromverbrauch.htm

    23 Watt compared to 55 Watt.

    Best advice: Try to find a fool and sell him the computer
    claiming strong the real power of real GHz and so on...

    Invest the money in a real laptop with Pentium-M

    Aw so i don't own a laptop...

    Okay, well http://www.expansys.com have the same style of notebook, yet with
    a pentium4M - and the battery-time is *also* 2 hours (approx) - so i dont'
    see the point in taking what i've bought back right now, do you?

    What you have here is a Desktop Replacement, low portability/battery life
    to make way for higher performance. And a lot of people still love these
    machines! Graphics professionals and the like who need great performance
    and are happy so long as they can haul the machine around their home or to
    the office. They still sell these things new all the time, so you might
    want to try selling it (eBay!).

    Now what you probably want is a "thin and light" which gives you a good
    slice of desktop performance, but 5 or 6 hours of battery life and a
    lighter package. There are also "ultra portables" but these have slower
    performance, smaller screens, and full-day battery life (12 hours).

    Look for a Pentium-M processor, not to be confused with Mobile Pentium
    processors (like Pentium 4-M). You might be turned off by the lower
    clockspeeds at first, but remember these are a completely new design, and
    typically do twice as much work in a single clock cycle as a regular
    Pentium. So a 1.6 Ghz Pentium-M is roughly on par with a 2.6 Ghz desktop
    Pentium (this is a rough estimate, please keep that in mind). But this
    confusion in the clockspeeds is why Intel has decided to give them model
    numbers instead.

    Next, remember to read reviews and opinions on notebooks, it will save you
    a lot of headaches in the future, start here:

    http://reviews-zdnet.com.com/4521-6527_16-5021302-2.html?tag=dir.tp

    (Ignore their quoted prices, you can almost always find cheaper configs on
    http://pricegrabber.com/).

    Last but not least, look into manufacturer refurb notebooks. You can save
    quite a bundle, and almost always get the same warrenties as the new
    notebooks. In the case of HP/Compaq, when I was buying a refurb from
    RadioShack a while ago, they told me all the refurbs had new screens and
    casing, and the harddrives were rebuilt! It was a while ago, so still
    might not be true, but with a great warrenty you should be okay, and the
    savings are huge.

    Hope this helps you in the quest for a laptop that suits you. :)
