Hello guys, I was just realized that my 15" UMBP took a very long time to sleep other than the UMBPs in the Apple Store that are using HDD as standard. In the stock MBP, I had an instant sleep when I close the lid (Like 1 sec then the white LED flashes). But in my MBP, I have to wait for at least 15 secs for it to be completely sleep. Is this normal? I also have waking up issues. My MBP takes longer to wake up from sleep than stock HDD based MBP. Does anyone know about this matter? I have Samsung PM800 256 Gb SSD. Thanks a lot. Cheers.
