    So I have this laptop, with Windows 7 Ultimate. When the laptop isn't plugged into the wall (running on battery), i can get maybe 10 minutes (if i'm lucky) of power before it just *POW* shuts off. There's no shutting down process. I can't turn it on after this until I plug it into the wall. I know when I first got this laptop, the battery life was about 3 hours (it's a beast laptop, not one of those 10-hour things). Now, when running on battery, it says it could last 30 minutes. But it lasts much less.


    Help?


    Quick facts:

    Windows 7 x64 Ultimate
    Acer laptop
    One year old
    Shuts down on battery power ONLY, after a few minutes of non-intensive process (internet, etc)
    Annoying


    Thanks in advance!

    Possibly the battery has lost the ability to hold much of a charge. It happens eventually, though it's quite sudden for a laptop that is just one year old. On certain laptops you can check the battery health in the bios.

    Sounds like either a battery fault (batteries need to provide a constant stream of power - or it'll cut off) or battery failure (i.e. it's losing its ability to hold charge, as above). All Li-on batteries have a 1-3 year life expectancy.

    It could also be that windows and/or BIOS has been mis-calibrated, thinking that it has 30 minutes of charge left when in fact it really only has 10. Because of this, when it runs out of charge early, windows is not expecting this and has no time to shut down/sleep/hibernate (it usually does this when the battery gets down to around 5%).

    First thing I would do is as suggested above check every setting in the BIOS

    But if you dont know what your doing get someone else to do it lol

    Buy a new battery and make sure you condition it properly.
    The main problem with laptop's is that we leave them on the mains power all the time
    so after time the battery is unconditioned for use and can only charge to a max of 10% or less
    so as a rule get into the habit of taking it off of the power and run it down to 20% before you recharge

    I may be wrong, and misinformed about this, but I was under the impression most laptops made in recent years have a safeguard against battery deterioration due to being on constant AC power. Namely a mechanism that closes the circuit to the battery if it is already at a full charge, or within a percentage range of being at full.

    The ASUS laptop I bought in 2007 still holds most of its original charge/capacity as I have recently tested with BatteryBar* and real usage even though it:
    - Has a dedicated Radeon HD graphics card in addition to the integrated graphics in the motherboard (the latter of which is of course, default off)
    - Has always been connected to an AC power source with only a couple bus/train trips taking advantage of its battery.


    In earlier years I owned an IBM Thinkpad during the Windows98 era; treated the same way, the battery was completely/permanently depleted after little over a year. If I remember correctly it was not a Li-ion battery, but NiMH.

    If what I have described is all correct and applies to the original poster's laptop as well, it's more likely that there is something malfunctioning or not optimally functioning in the laptop's power management system or the Battery's Battery Management System or perhaps both to some extent.

    Looking around the web at articles from blogs, shops, and apple I find a lot of conflicting information-- which may be why there is NOTHING on Wikipedia about "Conditioning" Li-ion batteries one way or another. After reading the Talk page for Wikipedia's Li-ion article I'm falling asleep so that's the end of my commentary.


    * BatteryBar (http://osirisdevelopment.com/BatteryBar/index.html) can show you detailed information about your battery wear and capacity.

    I bought my media laptop roughly three years ago (Packard Bell EasyNote SB series) and it's been hooked up to mains most of its life. It didn't have an amazing battery life to begin with (an hour at most, even with Eco mode tweaks) but it got really low after two years and now Windows is reporting it as a faulty battery (i.e. dead).

    I'm sure there is a battery management system for some (maybe even most) laptops, but certainly not all.

    Packard Bell still exists?!
    In the United States there was such a fuss when they were charged with using refurbished parts in "new" systems that they stopped being distributed through mainstream vendors and I haven't heard anything about them in over ten years..


    and technically, all working Li-ion batteries have a Battery Management System or they would malfunction

    I also have this problem with my laptop, and 3 other laptops in the house. And I think all you can do is buy a new battery. Because I guess batteries lose capacity after a while.

    if you rule out the impossible whats left is the truth

    so since the laptop does work if its plugged in the laptop isnt faulty

    the akku is the problem

    Wow, I knew that PB are slowly disappearing, but I never heard that before. This particular SB series laptop was part of a "Limited Edition" range where they used flashy, sparkly cases with colour themes. Mine is 17" so it's got the "chocolate" brown theme. It's a very nice laptop, but when I upgraded the CPU, I discovered they didn't use any thermal paste at all. I applied some of my own and got very worried for the following week because the fan was so quiet! Much lower temperature, much higher speeds, and a laptop that I'll still be using for another couple years (even if it has a dead battery)!
