Will not wake after closing screen
Help! Most everytime that I close my Macbook it will not wake when I open the screen again. I have to turn it off by holding the power button for about 10 seconds. I thought maybe the battery connector was loose so I took the bottom plate off today and checked the connection. Everything seems good other than some dust that I cleaned out. I deleted a couple of big programs today after I finally got it to turn back on thinking maybe they were causing it but that didn't help.
