I've discovered a bothersome problem with my MBP.

When the machine gets hot and its docked to my 30" cinema display, I get static-like white flecks across the screen. When the machine is cold, I don't get these. All cabling has been checked, and the display works fine connected to a G5 tower.

This issue has been reported to the Apple discussion groups, too, so I know its not just me.

I'm a little upset, since I usually connect my machine to my 30" when I'm working at home. I've purchased an Antec notebook cooler with two (quiet) USB powered fans, and it seems to be helping. Hopefully this will be a solution... I really don't want to have to start returning/repairing machines like others have had to. Because otherwise this machine is fine (no screen warp, no bad pixels, reasonably cool when running off battery power).

Sigh. Why do I keep buying first gen Apple hardware?? You'd think after 25 years of buying Apple products I'd have learned by now.

Maybe I'll tear it apart and re-apply the thermal paste...


Edit: with the machine resting on the cooler, it idles between 48° - 56°C according to CoreDuoTemp. I'll report back if the sparkles return.

The first generation theory is complete BS and I wish people would stop using it.

I have owned several first generation PowerBooks without a single problem.

Yes, the MBP gets hot and yes this is an issue, so I suggest that you send it back to Apple and demand that it get fixed.

If you open your MBP to reapply the thermal paste you will VOID your warrantee. Why would you even consider doing this? Makes no sense.

Yes.

And, yes.... You're mostly right about the 1st gen Apple hardware. I've owned many 1st gen machines that have been just fine. Just a smidgen bummed about the MBP. But a few classic examples do come to mind (and I'm sure there are more I'm not thinking of).

•Blue & white G3 - crippled IDE controller; data corruption on second drive
•iBook G4 - self de-soldering graphics chip
•G5 towers - chirping power supplies

I hear you about the MBP.

I called my cousin who just bought a MBP. I asked him if he was having any problems and his only complaint was that it is HOT AS HELL. I told him to download the firmware update.
