I have a 13" MacBook produced in early 2008 and running Lion 10.7.5. I tried to switch it on and saw a grey screen with flashing question mark. Using my iMac I found out how to safe boot and then ran Disk Utility. Verify disk stated laptop was all right but on running disk permissions the first line stated: SUID file "System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Mac OS/ARDAgent" has been modified and will not be repaired.
I have no idea what this means but could this be the cause of the grey screen. If so, what should I do to fix the problem? If not, what elso could I do to establish what is wrong with my laptop?
