MacBook Pro freezes after disconnecting the second display

post #1 of 24
Thread Starter 
Hopefully this is in the right section. My dad works as a teacher and his MacBook Pro has been freezing lately after he disconnects the second display, which is a projector (through the vga adapter). This is annoying because the computer locks up and he has to force reboot it to fix it. I've looked on Google and I can't find any relevant information on this issue, I tried resetting the NVram but the school seems to have put some lock on the computer that prevents you from changing sensitive parts of the computer (like resetting admin passwords etc...). I also saw that pressing command + F1 before disconnecting the cable works for some people but I haven't had a chance to test it yet. Does anyone have any information on this?
Thanks.

What OS? What model/year? What graphics card? Is there anything in the Console logs when it happens?

Can you ssh into the machine when it apparently freezes?

What machine is it? I.E. MacBook Pro 15 Early 2011.
What OS?
Gunner, I think that is a little on the advanced side there XD
I have seen this once before and it turned out the logic board had a failing GPU on it.

I have an issue with my monitor (TV) that goes something like this:

1. MBP connected to the TV
2. MBP is on, lid closed
3. TV is off
4. Turn on the TV
5. Turn on the TV
6. The TV displays no video. Neither does the MBP, and the display does not switch when the MBP is opened.

The reason I asked about SSHing into it is because the only way to recover my system from this state is to SSH into it. The issue seems to be the TV. I think internally, it's rapidly turning on and off the HDMI link/connection as it starts up, and the MBP is losing sync.

Or you can just pull the hard drive out and mount it on another machine. You know, there are easier ways.
OP, try doing a clean install if you an and see if it still messes up. If it does, you need a new motherboard.That or the monitor/tv is an issue.

Sounds like the Macbook Pro 2010 issue possibly. There is a repair program out for it but you have to prove this issue. I think it would be really helpful to have the serial number and look up the specs on MacTracker.

You said to get data. Pull the drive. Why SSH?
Nevermind. I now know what you meant.
