I bought a MBP 15 inch 2.66ghz brand new back in september. Since my purchase i have has several things that have been annoying the crap out of me. Issues: 1. Clunk noise coming from HD, I have read some posts and installed Hdapm which reduced the sound a bit (i have the 320gb 5400rpm Fujitsu) 2. I believe becuz of the clunking (parking of the heads) causes my computer to stutter (mini freeze for like 1-2 secs) while using my MBP.. 3. The battery used notify me that i had PLENTY of time to use even when i had below 50% battery life left, now (on Firmware 1.6) the battery tells me i usually have like 2:30mins of use when im at 85% or so battery strength left. and YES the screen is dimmed along with the keys.(i have calibrated the battery also) I went back to 1.6 firmware due to the notion that various people have had better success on their harddrives working "better" with stock, or aftermarket. I am on a CLEAN install of Snow Leopard... If anyways has any tips or many the same issues that i am experiencing PLEASE leave a post on here so i know im not the ONLY one with these issues....and if i am, that will help me figure out if my machine is a lemon or not... I would like to thank you all in advanced! -Herbert M.
