I've owned five (5) 17" PowerBook G4's!
I've had PowerBooks since I switched from PC's after nearly twenty years ago in
September
2004. I have yet to experience one single problem with any of the FIVE (5) PowerBooks I've owned to date. I've sold each one in order to upgrade to the next generation.
Not a single problem, NONE! Including ANY heat related issues.
Perhaps the reason is I have an aluminum notebook cooler since day one. The iLap from Rain Designs ($79.99 @ the botique) is an aluminum notebook cooler precisely matching that of the PowerBook itself. It comes in all sizes of PowerBook and MacBook Pro, 12" (now discontinued), 15" and of course a 17".
There no fans in this cooler rendering it silent so you won't need to occupy a USB Port as most other notebook coolers do.
The entire aluminum surface of the PowerBook and the entire surface of the iLap makes it one huge heatsink in their own rights. The iLap comes with two padded velour "bumpers", one for the swivel stand located on the bottom and the other is a removable wrist pad on the front which is removable. The purpose of the velour wrist pad to aid in preventing carpal tunnel syndrome.
The whole purpose of the iLap is the provide a better user experience and to provide a silent cooling which therefore will improve the efficiency of the notebook and in turn improve the productivity of the end user.
The iLap provides a natural incline to enhance proper posture while using the PowerBook and it dissipates the heat across it's surface evenly allowing the PowerBook or MacBook Pro to run cooler. Lastly, airflow is allowed to naturally flow freely underneath and around a PowerBook or MacBook Pro itself.
I have three (3) batteries and rotate the usage of each to wear them evenly. I'm satisfied with every PowerBook I've owned because they are simply the pinnacle of notebooks and you know what - you have to take care of them and give the attention they need to run smoothly.
What's the purpose of all this, it's far more productive to take care of your investment than complaining as each one of you are doing. There is a simple solution to your "problems" just go a find them and quityour bellyaching already.
Of course each and EVERY battery is going to cause some kind of heat, why, it's simple - it's a form of energy which comes from a power source providing even more energy - electricity!
How could it be that some of you have horrible luck and the rest of us don't. Grow up and stop your whining and deal with it. Apple would've recalled any and all faulty batteries because of one simple fact, becuase of people like you.
Imagine any harm happening because of this God forbid then we'd all see you lined up sueing Apple for negligence and seeking damages.
This company sells incredible HIGH QUALITY merchandise not some plastic piece of junk like Dell. Who else has an aluminum case? Only since Apple released the PowerBook a few have have sprung up but that is because just like Microsoft after the release they all ran to the copying machines and attempted to duplicate this incredible piece of technology.
Stop your crying and if you can't deal with it, sell them and rid yourself of your problems and get out of our forums already!
