My Macbook 6.1 don't sleep after closing the cover
Hello.
My computer don't sleep after closing it. The Activity indicator shows this fact, because it does not go "breathing" like every sleep. This is very annoying for my travels: the hard drive is not stopped. I don't understand this, because I haven't changed my preferences "energy savings" to completly standby. I read on other sites it would disconnect any devices, but even with this technique, the fate remains the same.
MacBook (13-inch Late 2009), Mac OS X (10.7.5), Hibernatemode is on the 3rd level.
