I have two issues, not major that the computer won't start again but small ones.... The first problem is that I don't have that light that tells me when it is sleeping or when it is turned on ect....Not sure how to fix it either. secondly, when I pulled out my hard drive from the mac...the original one. There was these rubber pieces...no where does it say on the upgrading your harddrive guide about rubber pieces being attached to the original drive. Do these have to go back on the drive enclosement as well? because right now they are not on the HD. I have a little bit of issues trying to put the rubber pieces back on.
