😕 I bought the Aluminum Porerbook in 2003 when it first hit the market, and it worked well up until I upgraded to Tiger. I am not saying that anything is wrong with the Cat, nor am I saying that it caused the problem. I am just telling you what happened. After upgrading to Tiger, I notice the computer would go to sleep intermittently after continuous usage. But the problem got worse and it would go to sleep even upon booting up. I went to the Apple Store and they did some checking and did some resetting. It seem to solve the problem. But within a day the same thing happen over again. I have "APPLE CARE", so I called up tech support and explained the situation. They sent me a box and I shipped the Powerbook to Apple. I called them up today to get as status on the repair and they told me that the hard drive is damaged due to an impact to the "Top Case" , and it will cost me $975.54 to replace the hard drive. WHAT????!!!. A few weeks after I bought the computer my cell phone fell on the mouse track surface, leaving a "pin head" size dent on it, and it never affected the mouse at all. Now Apple want to "RIP ME OFF" for $975.54. I Could buy three hard drive for that price. What is your experience? and what do you think about this. I am thinking of calling in CNN, 60 Minutes, Date Line, and Prime Time on this "RIP OFF" by Apple. 😱
