It happened again today: came in, pressed the power button for the MacBook Pro and instead of a login screen I got a blue screen. Two blue screens actually, since I’m using an external monitor and keyboard. Argh. The one year guarantee is just days away from expiring, so I thought it worth the time to find out at least whether I could reproduce the problem before taking it in. Sigh.
It goes like this: grey screen, apple appears, gear shows up and turns, blue screen. Game over.
I don’t know exactly when this behavior started, let’s say a very unscientific “lately”. And more often recently, already twice this week.
61 starts and shutdowns later…
There are a few peripherals attached to the laptop so I took the time to do a bunch of starts and shutdowns to try and see if any of them were the problem. The time seems to have been worth it (not only because I cleaned up my desk in the process).
It looks like the one condition when I can count on the blue screen to show up (not every time, but eventually for sure) is when I have the monitor plugged into the laptop *without* the MBP power adapter attached. The battery is charged, maybe not 100% but definitely not even close to empty. It happens whether or not the monitor is already powered on at startup.
I suppose a workaround would be to just make sure I have the power plugged in before starting up the MacBook Pro with the monitor attached. A pain, maybe, but for now it may have to do. I will talk to the friendly tech guy at the Apple store to see if there’s risk of more problems later, especially since the guarantee period is almost over.
Off to googleland to look for others with a similar problem, maybe even post in a forum or two. Argh.
Anyone out there experiencing this?
Just for the record, the culprits:
MacBook Pro, 10.4.10 (all updates as of today), 2.33 Core 2 Duo, 3 GB 667 MHz DDR2 SDRAM
Apple Cinema HD Display 23″
Apple 85 W Portable Power Adapter (guilty by absence)
