kkskks2 Posted December 26, 2015 Share Posted December 26, 2015 Hi all,I am using Clover UEFI, and I upgraded from Yosemite to El Capitan. After that, everything looks good, but "Sleep" doesn't work. When I try to sleep the system, monitor goes to black but the fan is still working. Then, about 5 minutes later, it reboots automatically. That is, I think that the system never sleep, and only monitor changes to black for 5 minutes and then reboot itself. Any solutions for that? Thanks in advance.

buttadeus Posted December 27, 2015 Share Posted December 27, 2015 I had this problem caused by a rtl8188 wireless adapter (removed it and sleep is working again). Others had it because of keyboard or mouse. Link to comment Share on other sites More sharing options...
