After I increased the ram from 2 to 4 GB, I found that it takes longer for the sr mbp to fall asleep. Sometimes it takes over 30 seconds. Is there any way to speed it up? I found it annoying to wait for the machine to go to sleep mode. Usually it is not a big problem but yesterday, I saw a girl walking nearby while I was using the computer. I put the computer in sleep mode immediately and tried to chase her. The machine took so long to fall asleep that by the time it was ready for me to carry it, the girl already disappeared.
