Hey there, I know this question has been posted before, but none of the solutions helped me. I am trying to fix a laptop that takes a few minutes to start up, i would say more than 5minutes. When i start the computer it would show the grey screen with the Apple logo and the little circle would just spin underneath the logo for quiet a while. After it comes off that screen, the screen would become blue for another couple of minutes before it goes to the login screen. I know the laptop is a little old, but even so i don't think it should take that long to start up. Once the laptop has started, it works fine. The other problem is that if it is left without being used for a while, the screen would go black and it won't come back on, unless i forcefully shut it down. Macbook Pro early 2008 (4,1) Inter Core 2 Duo 2.4ghz 2GB RAM OS Snow Leopard 10.6.8 So far i have tried a few different solutions and none have helped. 1. I have tested the hard disk with both the disk utility and apple hardware test utility and the result are that everything is fine. 2. I have replaced the hard disk with another one, run the same tests and the same results appeared. 3. I have tried both hard disks on another macbook pro that boots up normally and the laptop boots up normally. So i assume it's not a hard disk issue. 4. I have reset the PRAM (CMD + Option + P + R), and it didn't solve the problem. 5. Run both fast and Extended testing via the Apple hardware test tool through the use of the applications DVD disk and result was "No trouble found". 6. Tried different Mac OS (Leopard) and still the same problem. 7. If i try to load something from CD with holding C or opening something from a USB stick while holding the Option button, it will load it just as slow as from the actual hard drive. I may have tried other things too, but can't recall them at the moment. Any suggestions would be much appreciated. Thanks, Dean.
