Hi, Just noticed a problem with 2 month old MBP running Leopard. If I choose "sleep" from the menu bar, it sleeps but will not wake. Even if you hit the power on/off key, it won't wake up. You have to shut it down and then it reboots find. Here's the odd part. If you just close the lid, thus putting it to sleep, it wakes fine. Any ideas as to why this is happening would be greatly appreciated.
