I'm in the process of purchasing a second hand MPB (2007 model, 2.33Ghz C2D) for my on-the-go work, does anyone have any recommendations what defects to look for when I'm picking it up?
Lithium-Ion batteries go bad after just a few years, so being a 2007 model it is already almost time to replace the battery, or the laptop will be much less 'on-the-go' than you think.
In my experience with laptops, the first thing to go is the battery, the second thing to go is the battery-charging mechanism. Though if the battery is on its last leg you won't know if the charging mechanism is defunct till you replace the battery.
