I've got a new 17" MBP to replace my dual 1.4 G4; it's my first laptop. However, I bought it mainly to save on physical space my flat is very small and to provide a decent amount of power for design. I can also move it around the flat if I need to and may use it for external presentations from time to time. 95% of the time, it's running from mains power in clamshell mode, hooked up to an external monitor and keyboard/mouse. So two questions: 1) In the long-term, what's the best way to look after the battery in this situation? And... 2) Running almost permanently in clamshell mode; this won't damage the machine, will it? For now I'm running Quark 6.5 and CS1 in Rosetta it's about the same speed as the G4 for the next couple of months until planned upgrades to those two core suites, and have noticed the fans going crazy, especially when using Photoshop. Should I lift the machine off the desk, get some air circulating around it? Thanks for any advice.
