My work laptop (Vista `Enterprise') takes longer to wake from hibernate than it does to cold boot.
- AndrewDucker 16y agoBut that's hibernate - Sleep takes less than 2 seconds to recover from for me.
- Yaggo 16y agoI don't know how Apple does it, but both my iMac and MacBook wake up in a second. I guess they keep the ram powered up and only save it to disk (hibernate) when running out of battery (or after certain amount of hours?). Anyway, they are totally silent and consume very little energy when sleeping. That's how it should be. I love how the difference between sleep and hibernate is abstracted away in Apple's implementation.
- cgomez 16y agoYep, Apple laptops keep the RAM powered up until the battery level dips down to 20%, then it writes the contents to disk when the machine sleeps. It's called Safesleep and you can tweak this if you'd like by using a utility called Smartsleep.
- Yaggo 16y agoActually, according to the following sources, the content is written to disk _before_ entering sleep. This can be done very quickly because most of the data is already in swap file. http://support.apple.com/kb/HT1757?viewlocale=en_US http://support.apple.com/kb/HT1757?viewlocale=en_US http://www.macworld.com/article/53460/2006/10/safesleep.html http://www.macworld.com/article/53460/2006/10/safesleep.html http://moishelettvin.blogspot.com/2006/11/windows-shutdown-crapfest.html?showComment=1164433980000#c116443401770157410 http://moishelettvin.blogspot.com/2006/11/windows-shutdown-c...
- stuhacking 16y agoThe OP specifically mentioned saving RAM to disk. I don't trust the battery in this work laptop to hold the state in RAM overnight.
