I've been having an issue recently where after my MacBook (5,1 Alu. 2.4Ghz) is woken from sleep, displays (both MacBook + external) will not come on. However, the keyboard backlighting comes on and the sleep indicator changes its flash. The only option I am faced with is to shutdown the computer by holding the power button. Upon start up, "Problem Report for Mac OS X" comes up specifying that a panic has occurred: Interval Since Last Panic Report: 207534 sec Panics Since Last Report: 1 Fri Oct 15 20:40:08 2010 panic(cpu 1 caller 0x2a8ab2): Kernel trap at 0x002945e6, type 14=page fault, registers: CR0: 0x8001003b, CR2: 0x00e46000, CR3: 0x00100000, CR4: 0x00000660 EAX: 0x69eb5000, EBX: 0x00000005, ECX: 0x00000460, EDX: 0x00005180 CR2: 0x00e46000, EBP: 0x527eb698, ESI: 0x00e46000, EDI: 0x69eb9000 EFL: 0x00010206, EIP: 0x002945e6, CS: 0x00000008, DS: 0x09220010 Error code: 0x00000000 I recently reinstalled Snow Leopard but I was also having this issue prior to reinstallation. It started happening about a month ago. Any thoughts?
