"MacBook Pro Video Update 1.0 (Snow Leopard)
This update addresses an issue where MacBook Pro (15-inch Mid 2010) computers may intermittently freeze or stop displaying video.
For detailed information about this update, please visit: https://support.apple.com/kb/TS4088.
(that's the original doc from Oct. 2011 (No longer online) on the issue MacBook Pro (15-inch, Mid 2010): Intermittent black screen or loss of video. As of Nov 14, 2011, it's not been updated yet to refer to the 10.6.x updater and still lists service for 10.6.x users. It may be revised by the time you read this.)
System Requirements: Mac OS X 10.6.8"
Update: As of 7/31/2012, that apple doc (TS4088) (No longer online) had been updated to note if software updates do not fix the problem that they will service affected models for 3 years from purchase date, which may be extended as needed. (The emphasis/underline is mine, as wording is similar to the apple doc on 8600M issues that had several extensions over the years.)
"...Apple will service affected 15-inch MacBook Pro computers free of charge until three years from date of purchase. Apple will provide further extensions to this program as needed. This worldwide Apple program does not extend the standard warranty coverage of the affected MacBook Pro."
Last month (Oct. 26th, 2011 news) a reader with an affected MacBook Pro running 10.6.x (not able to apply the Lion update and none for 10.6 at that time) that took it in to Apple for service (per the doc) said he was told a motherboard swap was required for 10.6.x users. (Again at that time no 10.6.x update available.) I wrote him to ask if he'd had the motherboard replaced already - if not was curious if this update solved it. (Although the apple doc on the issue said if problems persisted after the update to get the mbp serviced by apple.)
FYI - He replied on Tuesday he didn't have the mb replaced yet, so he installed the update. Will report back after sufficient use to see if the problem is really fixed.
