I have 2 separate Macbook Pros. Identicle. Both running snow leopard. Last week one got a software update. After a reboot I get a black screen and the power light on the LCD release button but nothing else. No DVD, no DVI output, no chimes, etc. A couple days later the second MBP updated (it was off for a week) and after it rebooted I have the exact same thing.

One **** of a co-incidence if it's hardware. Thoughts?
