Having a laptop battery that drains quickly is one of the most annoying things I can think of. I bought a laptop over a desktop so I could use my computer anywhere and expect the battery to last enough time to get a decent amount of work done. Whenever I find something that can increase my battery life, I get excited. I recently stumbled across a firmware patch for MacBooks that does just that.

The patch was released in March 2009, but I did not find it until just now. According to Apple: “This update improves the ability of MacBook batteries to maintain a charge when the system is shut down and not used for an extended period of time. For more information about this update, please visit this web site: About Battery Update 1.4.”

The products that were affected are as follows: MacBook (13-inch Late 2006), MacBook (13-inch Mid 2007), MacBook (13-inch), MacBook (13-inch Late 2007), MacBook (13-inch, Early 2008), MacBook (13-inch, Late 2008), MacBook (13-inch, Early 2009).

If you own one of the affected models and are interested in giving your MacBook’s battery life a boost, head over to the firmware update page and click the download link.

  1. This is not for unibody Macbooks; I tried to run the installer and it said that this computer (the unibody Macbook) did not need this update.

  2. Don’t quote me on this, but I think this update solved the infamous MacBook screen flicker that I’ve learned to live with on my ‘road warrior’ 2006 MacBook (it only ever happened for the first few minutes after startup). I didn’t expect this, in fact I only installed it to breathe a tiny bit more life into a dying battery that gives an hour’s life at best.

  3. If Nick is right what about Unibody? Mine doesn’t do well when it’s not plugged in. My white Macbook holds a charge much better. I’m up to date, reset everything that can be reset. Losing at least 3% an hour while sleeping.

    I tried this update on my MacBook (13inch, mid2007) but it didn’t change the battery status, which is : not recognized by the system, though iStat (and System Profiler) gives me only 91 complete cycles…

    Could I get a free replace even if the warranty period is over?
    I guess this issue is caused by a bad battery and not by improper use, so this should be taken care of, right?

    Any comments or ways to solve this problem are very welcome!

    Thank you all!

    Out of warranty but under AppleCare? Apple replaces the bad/defective battery.
    Out of warranty without AppleCare? You’ll have to buy a new battery ($129 USD).

    1. Not true… Only if battery is under 300 cycles… Even under applecare

  7. [...] May 31, 2009 Macbook vs Netbook Posted by nkrama under Uncategorized | Tags: Computrons | No Comments  My 2+ year Macbook (”MB”) recently started acting strange, showing an “X” over the battery meter and working only when the power cord was plugged in. Luckily, the genius @ the apple store said that it only needed a battery replacement = approx $150.  [Note:  next time try this] [...]
