Hey guys, is anyone else having this strange problem?
For over a year I have been using an external monitor with my MBP. MiniDisplayPort to HDMI adaptor and HDMI to the monitor. Normally, it goes to sleep when I close the lid and both screens wake up when I open the lid. Now, out of the blue, it isn't working. It will still go to sleep normally, but if I open the lid, it will only wake up about 50% of the time ( I can tell its still sleeping b\c the power light is still pulsing). The other 50% of the time, when it does wake up, only the external monitor turns on. The MBP screen does no turn on. I have to go into the system display settings to "detect displays" for it to detect and wake that screen up.
Any ideas what might be causing this? It literally appeared out of the blue about two days ago.
Thanks for any thoughts!
