    Laptop battery on LMDE


    Hi guys, I have been using Mint 11 on my desktop for some time, and after buying a laptop recenetly, I decided to give LMDE a try. Win 7 runs on my lap full charged for 3 1/2 hrs bt LMDE Lxde 64-bit only for 2 hrs.

    My specs are
    Dell Inspiron N5110 i5 64-bit
    4gb RAM, 1gb Video
    500gb HD
    15.6"

    Please I love Linux bt the extra 1 1/2 hrs is drawing me to Windows.

    I'm a noob but the first places I would check are to ensure all updates are applied to your Mint install. Secondly, look in user system setting for power management and ensure they are appropriately set.

    I don't know whether this is your case, but Linux has had many problems lately with power consumption... especially from the kernel....

    A related issue, excessive heat, is why I'm no longer running Mint on my Dell laptop. I switched to bare-bones Debian Squeeze, at least until the power issue gets resolved.

    I had similar problem with my iBook and debian squeeze. battery life shortened and fan very often working: solved simply setting the CPU temperature, so battery life becomes normal: simple google for right setting for your laptop.

    could you please share a link where you find a solution?
    as far as I know, most of the power problems are due to the kernel...

    I am very interested on this topic too.
    In my case (Samsung NP300) the difference of battery life between win7 and linux (lmde-201204) is 3,5 hours vs 1,5 hours.
    May something not being working properly with the hardware management? I hadn't tried yet, but I think I could toast small pieces of bread just leaving them next to the laptop while running linux Anyway, if anyone has time I would appreciate every hint from you guys in this regard. I attach below a short summary of the system:
    Code:
    System:    Host: laptop Kernel: 3.2.0-2-amd64 x86_64 (64 bit) Desktop: Xfce 4.8.3 Distro: Linux Mint Debian Edition

    CPU:       Dual core Intel Core i3-2330M CPU (-HT-MCP-) cache: 3072 KB flags: (lm nx sse sse2 sse3 sse4_1 sse4_2 ssse3 vmx) 
               Clock Speeds: 1: 800.00 MHz 2: 800.00 MHz 3: 800.00 MHz 4: 800.00 MHz
