TheSmokeMonster Level 4 Level 4

I've calibrated, I've taken out the battery and held down power, I've unplugged everything but the ethernet cord, turned keyboard lights all the way to 0, turned display to mid brightness, quit applications... basically made my computer useless and all I have is:

notice the time, this is basically with nothing running but the os. (checked in activity monitor before unplugging)

see how I only have 97% after battery is done calculating? and it only says 2:31hrs! again notice the time

and lastley this is what it looked like when I open up chrome and I'm on the login screen for apple support. looks like i've lost over an hour in 4 min!


Could it be because I have 8gb RAM? however I only have 2.17gb being used while performing the last part of the this test.

Ok looks normal.

 

I hate to say it, but after 2 years, if you've only done 14 cycles, that's probably the reason it's not working as well as it should.

 

Not using the battery can be quite damaging. Especially if it's full most of that time. Note storage instructions call for 50%.

 

But let's have a look at the design capacity out of curiosity.

 

In Terminal copy / paste this command & post the results:

 

ioreg -w0 -l | grep Capacity

    That's unusual.

     

    Do you have AppleCare?

     

    What is happening in your Activity Monitor?

     

    Sort it by CPU% & what are the 3 biggest processes & their % values?

  • TheSmokeMonster Level 4 Level 4

    It says battery normal just like the list I gave from System Information says about the battery.

    and also as I stated nothing was giving me crazy spikes in CPU since there was nothing active except for thing the OS needs to run.

    Sorry, not used to getting that much useful information in the first post. Very good!

     

    Have you timed it? How long does it actually take to go flat?

  • TheSmokeMonster Level 4 Level 4

    40 minutes if I'm really using it the way I usually do. haven't just let it sit and waited though. I actually have to use it from time to time for work

     

    the only apple care I have is with Lion

     

    could a firmware update fix this and what does UPS mean. does my battery look "normal"?

  • AussieDJ Level 4 Level 4

    Run the programs you normally run & then post a screenshot of your activity monitor.

    I feel like I'm repeating myself here, this is a brand new battery as it says in the subject of this thread. That's why there are only 14 power cycles.

     

        | |           "MaxCapacity" = 4268

        | |           "CurrentCapacity" = 4268

        | |           "LegacyBatteryInfo" = {"Amperage"=182,"Flags"=5,"Capacity"=4268,"Current"=4268,"Voltage"=12587,"Cycle Count"=14}

        | |           "DesignCapacity" = 4600

    Sorry, I didn't realise it was until just then.

    That's because you are!

     

     

    Have you already said where you got the battery from, or who put it in?

  • TheSmokeMonster Level 4 Level 4

    Got it new from an apple authorized dealer but I can't find the receipt at the momment so they won't exchange it. I installed it on my late 08 MBP

  • AussieDJ Level 4 Level 4

    Why not? The batteries serial number can be tracked back to that store can it not?

     

    Ask Apple to intersede if you need to.

     

    Can you press the LED indicators on the side and tell me if anything unusual happens, like it going back & forth or flashing?

  • TheSmokeMonster Level 4 Level 4

    I've got the box and the serial is an internal thing but I was told since I bought it from a place that wasn't specifically an Apple Store, that it's not going to be in Apple's systems. the indicator on the sides light up like normal.

  • AussieDJ Level 4 Level 4

    But it's an AASP, which means they buy genuine parts from Apple?

     

    Perhaps the battery is, a genuine part?

     

    I would have thought Apple would have a record of that.

     

    AASP's have to comply with certain things I thought.

     

    And you should have buyer protection laws in your country concerning warranties of goods. Surely they should be replacing this battery under the law?

  • TheSmokeMonster Level 4 Level 4

    not without a receipt.
