It seems Nvidia's mobile woes are far from over, at least according to AppleInsider. The first issue is jerky scrolling, but this should be easy to fix via a software update; but the second issue is far from benign. Certain MacBook Pro models are apparently affected by the so-called "black screen of death" issue.

It manifests itself, obviously, by the appearance of a black screen while gaming and a total system freeze, remedied only by a hardware reset. The issue seems to be limited to the 9600M GT, and several users have reported core temperatures in excess of 100°C.  At the moment it is unclear if any other GPU is affected, but most users are moaning about the 9600.

Apparently, it's possible to fix the issue using manual fan control, thanks to SMCFancontrol. However, this fix comes at a price, as most users are reporting their MacBooks have stopped freezing only after they've adjusted the GPU fan speed to 6000 RPM. Obviously, a tiny fan spinning at 6000 RPM isn't a pleasant thing to have around, unless you're deaf. What's worse, even this unpleasant fix doesn't work all the time.

We're still waiting to see what happens. Either the issue is limited to a very small number of machines, as most users report theirs were produced in the past few weeks, or Apple will be in a bit of a mess. It's quite possible they'll go the way of HP and several other vendors who, when faced with Nvidia's overheating 8600M chips, were forced to issue hotfixes which downclocked the GPU and increased fan speeds.

Nvidia lost face back then, as vendors didn't hesitate to point the finger in its direction, and if this latest issue persists, we have no doubt Apple will do the same.
