My macbook has been having sleep issues. Sometimes when i close the lid all the sudden I will hear the startup chimes and when i open the lid it will be on the boot up screen about 80%. Then it will load up and apps will say do you want to restore previous sessions and such. I took my book into the genius and he told me that they probably need to replace a cable to the superdrive. I was pretty shocked because that sounded pretty far off base. My question, so do i entrust my book to a pretty much known doofus? I was thinking theres something wrong with the os. Can someone suggest a way that I can fix it myself? Ive never reinstalled osx on the numerous macs ive had. Ive upgraded the os and its been pretty much a clean install and fairly automatic. I dont want to lose anything and i dont want the stability to decrease. The book is very stable as Ive only seen a kernel panic once and that was a long time ago which i have since deemed a fluke. I just want my mac to sleep normally! PS im 1 week from my 1 year anniversary w the book, its probably a good idea to get the applecare extension am i right? It is $250. A new book is $1000 Kind of hard to justify.
