I have a 2.4 MacBook (late 2008) and I cannot get it to sleep when I close the lid, or sleep from the main menu, it clicks, the apple light flashes and it wakes. Even when I try to shut it down from the main menu it restarts, the only way I can get it to power down is by holding the power button. I have read loads on various forums about retsetting pram, smc etc. but nothing seems to work. It finally gave in and would not load past the grey screen so last night I decided to format and do a clean install of snow leopard. All went well, got everything set back up but the sleep issue remains as before, what the he'll is going on, was convinced that a clean install would fix the problem but no. Anyone else had this and how did you get it resolved? It was only bought in November, what will apple do if I take it Anyone?
