charliebounce Posted August 13, 2014 Share Posted August 13, 2014 Hi All, I have a this laptop and it works almost perfectly under Mavericks (Specs below). Just one problem, Sometimes when I close the lid, it does not sleep at all. This happens approximately 1 in 5 occasions. On the other 4 in 5 occasions, it will sleep just fine. I can tell that it is sleeping because it disappears from the network when it sleeps properly. I also always check any assertions (pmset -g assertions) to ensure that no background services are preventing sleep. When I use the Apple Logo->Sleep from Finder and close the lid, It will sleep just fine every time and I can safely close the lid once the keyboard backlight turns off. -Intel i7 4510U -Intel HD 4400 (1920x1080 kexts from 10.9.1 to enable HDMI)-8GB RAM-ALC283 Audio (small issue with headphone audio)-Replaced Intel Dual Band 7260-N with Broadcom BCM94352HMB. Have any of you guys experienced this issue before? Is the away (maybe a small App) that will force sleep every time I close the lid. I have tried a few DSDT patches (thanks Rehabman) but no success yet.

mendietinha Posted August 13, 2014 Share Posted August 13, 2014 if sleep is working perfectly from the apple menu and rarely fails from closing the lid, i guess you don´t have a real sleep problem.

charliebounce Posted August 13, 2014 Author Share Posted August 13, 2014 Yes sleep is working perfectly from the Apple menu. Its just that when I close the lid, sometimes it sleeps and sometimes it does not sleep. On occasions when it does't sleep, the lid does not turn on when I open and I have to force turn off by the power button or access from another Mac using "Share Screen" to shutdown. So it clear that on this occasion it did not sleep.
