HT1490 If I use my mabook pro 2011 more on AC power does it help increasing battery life

Help me in  understanding  this problem?

Even when you are constantly plugged into the AC outlet when you are using the MBP, the battery will slowly discharge during the times when it is idle.  When it drops below 95% charge level the battery will again be recharged to 100%.  These 5% discharges will eventually add up to an entire cycle.  This may take several weeks.
If you follow the instructions in the link provided by OrangeMarlin, you will gain the maximum useful life of your battery.
Ciao.

    Using my macbook pro whole day with the power adapter , will it affect my battery? Please help

    It doesn't affect the battery. You can use your MacBook Pro plugged in all the time without damaging the battery. You only have to be sure that you unplug it and run a battery cycle (drain the battery without letting the Mac turn off and charge it fully) at least once a month to keep the battery life.

  • Power Manager Setting To Preserve Battery Life When Using A Docking Station

    I have a Lenovo Thinkpad X220 which is about 19 months old.  When at work, the computer is in a Lenovo docking station.  At the end of the day, it is removed and any further evening use is typically on the battery.
    Yesterday, the battery symbol in the tray at the bottom of the screen displayed a red X on it and indicated that there was an "error".  I presume from this that that battery is dead and needs to be replaced.  I am surprised by the comparatively short life of this battery.
    I was thinking that perhaps the use of the powered docking station played some role in shortening the battery's life.  For example, it may have repeatedly overcharged the battery.
    Is there a Power Manager setting that will reduce the likelihood that the battery is being overcharged while in the docking station?  In the future, is it feasible to simply remove the battery before inserting it into the docking station so that this won't continue to occur?
    Thank you.
    (I did a search of the community's knowledgebase, but didn't find anything on point.)

    Hi,
    Welcome to Lenovo Community Forums!
    I’m sorry to hear that battery of your Lenovo ThinkPad X220 had undergone wear and tear and has to be replaced.
    Capacity of a battery declines as the battery ages, with the number of charge cycles and time at high temperature. Under average usage patterns your battery maintains approximately 70% of its power capacity after the first year of operation.
    Most laptops today use lithium Ion (Li-ion) batteries. Overcharging Li-ion batteries is not a problem and does not affect the battery life span. These batteries have an internal circuit to stop the charging process at full charge. This is why the Li-ion batteries are more expensive. The only way for the Li-ion battery to overcharge is if the charging system malfunctions, and then the battery will heat up while in the charger. Older laptops use Nickel-cadmium (Ni-Cd) and Nickel Metal Hydride (Ni-MH) batteries. They require more maintenance than Lithium Ion batteries. They must be fully discharged and then fully recharged so that they don't lose battery life.
    Refer this document to see the tips on how to increase the battery life.
    Hope this provided enough clarity for your query!
    Best regards,
    Mithun.

    Ok Fellas, let me give you a clue:  Games, particularly those that make heavy use of graphics and sound are notoriously power hungry.  In fact, when I was in the Navy many years ago, the folks working on the NTDS (Navy Tactical Data System)  computers used a version of Space Invaders to load test the AN/UYK-43 computers.
    I have also noticed that all of my laptops (I have a brand new Toshiba dual core, an older Toshiba single core, plus 2 Dell dual core machines) have significantly shorter battery life when I play Company of Heroes than when I am just reading e-mail or surfing the 'Net.  I have also noticed the same behavior when I play games on my 4th gen Touch and my iPhone 4.
    The fact is, iOS 5 did make some major improvements as well as adding some nice functionality like iMessage, wireless synch, and such, but the down side is that depending on how you use the device battery life can be shorter that what you may have experienced with pervious versions of iOS.  Its just the nature of the beast...

  • HT1490 How to use MacbookPro 15inch (late 2011) battery?

    When i bought this laptop, the technician told me that since the battery is not removable, I should
    1. plug the power adapter when the battery is left around 15-20% .
    2. plug it out when it is green and battery is 100% so that battery will not be over charged.
    So that means I'll constantly be using the battery? Aren't the computer automatically stop the charging when the battery is full? because when it is full, the system report indicated under charging information that the battery is not charging, and power source: power adapter.
    3. I've been following point 1 and 2 for the past few weeks and found out that my 100% charged battery lasted only 2-3hrs with full brightness and Adobe Photoshop CS4 on, I've been using my macbook white mid 2007 in similar style but with a swollen battery and it lasted 2hrs as well. So I suspect that maybe I need a calibration so I found this article but it says no calibration needed. Really?
    4. I also read something about raid utility which automatically calibrate the battery so i clicked raid utility to check out but a window pops out and said raid utility is not supported in this computer.
    I am very confused can someone tell me what is the correct way to keep a longer lifespan for battery? And if the information that i got is correct? Thanks a bunch!

    Responses to your queries:
    1.  Yes, if you reach that level.
    2.  you cannot overcharge the battery.  The MBP will not allow that.  When you see 100%, the power adapter is powering the MBP.
    3.  Full brightness and Adobe software will put a large load on your battery.  2-3 hours is not out of line for that situation.  Use the power adapter instead.  Swollen batteries should be replaced.  Calibration for new MBPs is not needed.
    4.  I am not familiar with what you are refering to.

  • Display issue - My macbook pro 2011 detects my display but does not display an image

    Hi, I am having a problem connecting my MacBook Pro (2011) to my HP 2511x display.  I used the display all morning with my mbp connected and closed.  When I came back, after the computer went to sleep, I cannot get any image on the display.  The computer detects the display but no image appears.
    I have tried-
      Installing the latest firmware and software updates
    restarting both the computer and monitor
    trying all of the possible display arrangements and settings for resolution and refresh rates
    Also I am connected using a minidisplay to DVI adaptor in the thunderbolt port.
    Any and all suggestions appreciated.
    thanks.

    Hello Aminetti,
    It sounds like your computer goes to sleep, and will not wake up, so you must manually restart your computer. I recommend the troubleshooting in the following article:
    OS X: When your Mac doesn't sleep or wake
    http://support.apple.com/kb/TS5357
    Reset SMC
    Reset NVRAM/PRAM
    Test with external devices disconnected
    Try Safe Mode
    Try another user account
    Thank you for using Apple Support Communities.
    All the best,
    Sterling

    Try Troubleshooting the MagSafe adapter
    Thanks for that link.  It did provide some diagnostic tools to see if the adapter is the culprit.  I don't believe mine is.  My situation, MacBook Pro 8,2 - early 2011, 2.3 GHz i7.  I'm experiencing, while on the adapter, after the battery charges to 100% a slow drop (while connected to the power adapter) to 98%, 97%, etc.  Unplugging the adapter for a bit will again bring it back up to 100% but it again starts to drop.  I don't think it's the battery - have good on battery performance (in bare bones boot - a special user with no StartUp items) I can get 5-7 hours.  I suspect the power adapter - one glaring issue: I have a CAT who thought it cute to chew on the cable but I couldn't tell if it was superficial or had actually damaged the wires inside past the protective sheath.  I suspect this could be the issue and have ordered a new adapter.  My wife suggested coating the cable with lemon juice to make it less tempting for the cat to bite on.  This isn't the first cable this cat (never caught "red handed") has chose to chew on.  My Jawbone charge cable was completely severed.  I took measures to make the cables less accessible but the damage had already been done to the Mag Safe Power Adapter.  As I said, my monthly "battery exercise" fully charges the battery - it is this mysterious battery percentage drop that has me wondering.  I read somewhere that some are blaming Mountain Lion, I'm not so quick to do so until I get the new adapter.
    This post may have been better off in a new topic, but since we're talking about the Mag Safe Power Adapter I thought it would be okay here, especially since the link to the KB article gave me ideas on what to look for.  The pins in the cable were all up, I presume the middle pin is different and will look different as to its height compared to the two outboard/inboard pins, yes?  There was no issue with the laptop end of the connector.  I did not switch out the "duck head" with the long cord though.  With the cable damage issue I thought I'd wait and see.  Now that I think of it I could have borrowed my wife's adapter - same MBP, almost, but should both have the 85w adapter.  We'll see...

  • New macbook pro 2011 won't eject cd - jammed? help?

    My macbook pro has a cd inside and it won't show that it has anything inside - but I know its in  there and can't get it out, help!

    Start the computer up while holding down the trackpad button. Hold the button down until the drive ejects the disc.
    If that doesn't work, try this:
    Restart the computer. Immediately after the startup sound, press and hold Command+Option+O+F. Release the four keys when you see a white screen that says "Welcome to Open Firmware." At the prompt, type *eject cd* and press Return. The drive should eject your disc, and "ok" will appear when the action is complete.
    Type mac-boot and press Return to restart the computer normally.
    Here's another method:
    Go to Applications/Utilities and open the Terminal. In a terminal window type *drutil tray eject* and press Return. After the disc is ejected, quit the Terminal.
    If any or all of these methods cause the drive to make its usual eject sound but the disc still doesn't come out, the drive has failed mechanically, and will have to be physically dismantled to recover the disc. If none of these methods causes the drive to make any sound or do anything at all, the drive isn't getting power, and the machine will have to be disassembled to find out why not and correct the problem.

  • Mac Book Pro 2011 (Installed with X Yosemite) Problem. Help!

    I tried to start up my Mac Book Pro and it took me to the screen where you choose the user. I click on my account and put in my password. A grey loading bar appears below. It gets about a third of the way there and then the whole computer shuts down. Just shuts off like I pushed the power button. So I tried to Safe Boot but my computer doesn't seem to recognize it as a Safe Boot for when I hold shift upon it restarting, it just takes me back to the "choose your user" interface. So then I tried the Utilities screen which I was able to open. I tried to repair my "MacintoshHD" Disk (The top one in the left column) and it said that it was unable to fully verify the disk. I kept trying and this fixed the problem (I think?) since it stopped saying it couldn't verify it anymore. I went back to the "choose your user" screen and still no dice. What should I do? Is there any way to save my files on that account? Any help is appreciated.
    Thanks,

    My Mac tech friend tells me there is a pending class action lawsuit about this problem. So stay tuned.

    Thank You

    I was actually able to upgrade to the newest software, iOS 5.1.1 without connecting to my computer/iTunes but rather directly through my phone when I was home on Wi-Fi. After the upgrade I plugged my phone into a different USB port at the back of my computer and was able to do a full restore. I really don't think the USB port had anything to do with it because I use the same front USB port all the time with my external hard drive and other devices wuth no problems at all; regardless of what the actual solution was, I am now able to connect to iTunes and upgrade/restore without any problems so that half of my problem is resolved.
    I have yet to leave my house since doing the upgrade/restore so I am not sure if the problem with my phone crashing when I use the interent on the 3G is still an issue. I will test it today and tomorrow and give you an update.
    Thanks
