Not much of one, but tell me about maintenance. Such as canned air on the vents or if the shop does this for you.
I have recently had my laptop monitor blank out on me, and it's now happened twice in as many weeks. So, am a bit worried as to what is happening.
I have hooked up my laptop (Dec 2010, 13 in MBP, runs on OS X 10.6.8) to an external monitor and use it along with a bluetooth keyboard. Earlier I was using a connecter bought from Micro Centre, but when faced with these issues I decided to get an original Apple connector.
I think I have only had these blackouts on the monitor whenever I have been watching a movie. First, the laptop monitor goes blank, and then the external monitor a split second later.
The only way out is to hold down the power button and shut down the machine.
So, what is probably happening here, and how can I prevent it?
