I purchased a new 21' mac in February 2012 with wireless keybaord and magic mouse. The keyboard eats battries  once a month. I  contacted Apple store, Birmingham,UK and they replaced the keyboard with question. I month later batteriesdead again. I spoke to Apple care, the tech guy ran thru a series of checks to see if keyboard was set up correctly and was the Mac not drawing too much power from keyboard - everything Okay. 1 week later batteries flay again!


New batteries fitted today. If these fail I will contact Apple Care again.


Hopeless in Worcester,UK.

iMac, Mac OS X (10.4.11)

    I purchased my iMac with a wired keyboard for 2 reasons.  One, I wanted the numeric keypad.  Two, I didn't want to be bothered with batteries.  I have a Magic Mouse and it does eat batteries though not as frequently as your keyboard.  Some people use rechargeable batteries for both the keyboard and the mouse.  At least you're not buying batteries as frequently.


    Unless you have a pressing need for a wireless keyboard, you might consider switching to the wired keyboard.  You might also consider the rechargeable battery alternative. 


    I suspect that the wireless keyboard and mouse are like children's battery operated toys in that they all eat batteries.

    Thank you Tanya for your comment.

    I have put rechargeable batteries in the keyboard now - see how long they last?

    I did look this morning in the Apple store for a wired keyboard and could not see anything.

    I am interested in the  theory of magic mouse interferring with power of the wireless keyboard and if batteries go flat again, I  will plug in my Apple wired mouse, see if it makes a difference.

    Also the theory that the keyboard is not automatically powering down after use- a fault.

    A bit difficult to test if it powers up on touching the keyboard keys!

    Thank you linc for your comment/solution.

    Are you saying that if I follow your suggestion it may resolve the issue?

    Fully charged batteries fitted to I-  Mac  wireless keyboard on 15th Sept. 2012.


    Now I am getting the message Keyboard batteries low.

    I checked thru System Pref. and sure enough batteries shown as only 18% charged.

    What is going on ?????

    My friend says his wireless KB lasts for months , I need to ask him if he has a wireless mouse!


    Hopeful still.

    .I have now discovered how to turn off the keyboard, and hey presto batteries are fine!
