Leopard is sucking the life out of my battery!!

I swear that since I upgraded to Leopard, I have seen decreased battery life on my MacBook Pro.

I frequently bring out my notebook Mac during my lunch hour at the studio to play a bit of Halo after munching my midday meal. I used to be able to play through the hour without the AC adapter, but since upgrading to Leopard, I am interrupted during my game by the “running on reserve power” warning. If you have ever been staring down an oncoming Banshee and had another application intrude with a warning, you know what the result is–death!

It seems my problem is not unique. MacFixIt (requires a subscription) has been following the story since November 23rd. For those of you who have not subscribed to MacFixIt, HardMac has a summary. If any of you are experiencing the same difficulty, please let us know in the forum thread associated with this post.

Hopefully, Apple will be issuing an update that will restore my battery’s previous power. But, in the meantime, I guess I’ll be reseting my Power Management Unit.

What makes Apple’s Power Mac G5 processor so hot

58 million transistors can drive incredible Power! Apparently, Apple appreciated the choices IBM processor architects made when designing the 970 family. This article provides the 64-bit architecture big picture for the 970 family (A.K.A. the Power Mac G5) and the critical issues in IBM’s 64-bit POWER designs, covering 32-bit compatibility, power management, and processor bus design.
