    Huh, I was thinking of posting the same topic. I just got a new laptop last week. The battery life so far is great, bit I'm also looking for tips and tricks.

    Since I got my laptop, I'd use it on the battery until it's down to about 10%, fully charge it, and then go back to the battery. I'll then charge it back up at night.

    Older batteries would develop a "memory" but I'm not sure if newer ones do. This memory would develop if you only run it down to 40% then recharge, then down to 60% and recharge and do this repeatedly the overall charge available would decrease.

    The way to clear the memory was to completly cycle the battery a couple of times. Where you run it out of juice till it won't turn on the computer. Then let it sit for about 24 hours, then FULLY recharge it....just let it sit on the charger for 24 hours or so. Then repeat. This cycling would help to keep memory from developing and provide more charge over longer periods of time and help extend the batteries useful life.

    I'm not so sure this issue is present with newer styled batteries tho.

    Run less background programs... turn down the brightness of the screen, turn off the Wi-Fi fuction when not in use... and other major ones are mentioned above.

    NEVER drain a lithium battery if you can help it.

    If it's Lithium or Lead, Leave it charged.

    Was thinking about the same topic myself, I recently bought a laptop and the battery life is poor. I'm pretty pissed!

    Perhpas you need a larger capacity battery. I've got an 80 Whr battery and it'll run my 17" laptop on max performance for 3 hours, no prob. I'll get even longer if I put it on max battery. And yes...I had to pay more for this battery but IMO it's worth it.

    My sister's 12-cell battery lasted 8 hours when she first got it. Now it lasts around 4 hours or so.

    I hate the fact that the wireless shuts off when the machine goes to standby, so I don't use it.

    change your wireless mode to something else besides constant awake mode.
    turn off bluetooth, if you have it
    don't use the cd drive (rip dvds to hard drive if you want to watch them)
    replace the 7200rpm hard drive with a 5400 rpm
    screen on minimum brightness setting
    buy a higher capacity battery

    My work gave me an IBM ThinkPad. I've never had a laptop before, but the batter seems to last for like 2.5 hours. Is that good or does that suck? 99% of the time I leave it plugged in at work, anyway.

    My laptop battery sucks ass. I bought a $650 compaq Presario from Fry's a few weeks ago, and my battery only lasts about 2 hours at the most. I guess shitty batteries are part of the cost cutting.

    Don't keep it plugged in. I've kept mine on charge everytime I use it for the last year and now I only get about 30 mins from it whereas before I had 2-2.5 hours.

    thats what happened to my laptop after a year. it was a no name brand, syntax desknote, cheap ass shit

    then later on, the battery just wouldn't charge, and finding a new battery was a bitch, because the company i bought it from went under. i finally found a new one for only $120!

    i said fuck it and ended up selling the piece of crap on ebay, didn't lose too much

    Set your screen to turn off when you close the lid (but prevent it from going into standby when you do that), and close the lid whenever you're not using the laptop for a few minutes.

    keep your laptop plugged in as much as possible.

    heat is a huge killer of battery life, so some people will go as far as to take out the battery if its going to be on a desk plugged in for a couple of days.

    By the way, when I meant 'keys to a long laptop battery life', i meant over time.. like months or years. Not meaning "while its unplugged".

    Your battery is going to have a maximum number of recharge cycles before it needs to be replaced. So every time you discharge it, its life gets shorter. If you are plugged in 90% of the time just take the battery out and put it in your bag so you have it when you need it. Lithium batteries should store their charge pretty well over a few weeks time. Just toss them in once every couple of weeks or so for a few hours to top them off.

    i have no idea. I have a compaq presario 700, and although it's fairly old now, the battery completely died after only 1 year of use. I never got around to replacing it.
