A Fix for MAC OS X Lion reduces Battery Life

I tried to find out if there is a fix to the shorten battery life after the Max OS X Lion upgrade. Finally,  I found a fix. At this stage I am not sure if this is a real fix because I haven’t waited long enough to see how long my Mac Book Pro can last after a full charged. I can confirm that this is a real fix after I tested it for a few hours without the power supply connected to my mac book pro. I could get 6 -7 hours under normal use (before apply the fix, I could only get 3 hours use). If you are having a shorten battery life issue after you upgraded your MBP to Lion. I highly recommend you try the follow step. According to the Apple Support forum, these keys are to reset the power management module in the MBP.

The method was posted on Apple Support Forum as follow:

**** Thanks Justin’s comment below, please ensure you have the power supply connected when you do this****
1. Turn off the computer.
2. Hold down Ctrl+Option+shift
3. While holding down these button, press and hold the power button as well.
4. Hold all buttons for at least ten seconds.
5. power back on the computer.

After I have done this, at 98% battery level the battery life timing was showing 9:15. It seems longer than beforer I upgrade. Anyways, this reading at least make me feel more comfortable. I will let it run and see how the battery consumption is like after applying this “fix”.

Upgraded my MacBook Pro to OS X Lion

OS X Lion released, I can’t wait and upgraded my MacBook Pro to the OS X Lion from the App Store. It took me around 1 hour to download the  3-4 gb OS X Lion Installation file. and it took another 40 minutes to install. It is very easy for someone who doesn’t know how to operate computer. It is same as what Apple advertised on their web, “Just a few click” you can install OS X Lion on your Apple machine.

The next thing I am going to do is to upgrade to OS X Lion on my hackintosh at home.

But one thing I notice on my MacBook Pro, the performance on Lion is worst than the previous OS X on my Macbook Pro. My Macbook Pro is running on a Quad core i7 chip with 4gb memory which is better than the new Macbook Air, however, I notice a slow down on opening applications and takes longer time for boot up.

I will see other than that if there is any other different on this OS X Lion.
