Hello Iain, >From a hardware guy; If you really need hibernate, use it. No laptop was designed to stay powered on continuously despite the features in software and hardware. The system will collect more dust internally than if powered up and down. Heat is EVIL on electronics no matter what you do. Power consumption minimization (at this point in time) is still quite young and there are all kinds of non published issues with all sorts of memory and chips. Fans do not have the mtbf rates any where near what the published times are for processors. I could go on and on, but you get the point.... If you need hibernate, use it. If you do not, your hardware will last longer being powered down. Don't just hibernate or allow other users to do it, just because they are lazy. Several efforts are bearing fruit for fast (parallel) boot these days..... hth, James
