I keep hearing these stories about how someone demanded their screen be replaced because of 2 or 3 dead pixels. Well when I get a Powerbook I don't want any of mine to be dead, 1) so say you have 2-3 dead pixels, will you be able to notice them? 2) Or are they only found through a software specifically designed to find them? 3) If so, let me kno of a cheap one please.

Thanks in advance

You'll be able to tell if you have a dead/dud pixel or not - there's no software that can find them. It's a visual thing.

Just look at your PowerBook's screen after you turn it on. If you see a pixel or two that is permanently stuck at that colour (usually black or white) then you have dead pixels. I think the rule for Apple is more than 5 dead pixels gets you a new replacement.

must have been a cluster of pixels then because pixels are only red blue or green

well, i'm pretty sure it's only one...talking to the mac people (a long time ago when it first happened and i was young) that was their diagnosis. I think it's gone...maybe not...it's only like the size of a pin point.

I had one that was green, but I got a strong paper towel, soaked it in warm water, ringed it out real good and rubbed the pixel with it and it fixed it.

Why would you be worried about dead pixels if you couldn't see them?

I should warn you about getting a new PowerBook with an atrofied pilfer grommet. This is a common problem. You can't see it, it doesn't affect the laptop in any way, but you can detect it using 100,000 lines of code (which you can buy off the Internet for $300).

Make sure you don't buy a PowerBook with an atrofied pilfer grommet. If you find your PowerBook has an atrofied pilfer grommet, demand Apple replace it free of charge.

if it doesn't affect the laptop in any way, than why tamper with it. let alone buy a $300 program for it.

First off, you can see dead pixels. I don't know who's saying you can't... but I'm staring right at one this moment (albeit, its on my sony vaio). Secondly, some people are more bothered by this than others. Finally, a small number of dead pixels may be considered acceptible by the manufacturer (helps keep the price of these LCDs in check).

OR you could just avoid Dead Pixel Paranoia by going to the Apple Store and before they charge your credit card, INSIST that the EXACT Powerbook that they intend to give you be brought out from the back room and plugged in at the service desk. If you have to, speak to the manager to make this happen. If you make it clear that you intend to purchase that day if nothing is wrong with it, they should be willing to do this.

Use the Display feature and TextEdit to compare the screen in a mostly blue and mostly white background. If there's a dead pixel, you will see it. I definitely saw one when I did this, and I told them to march that piece of trash right back to the back room and bring me another. This avoided the little Apple trick of selling you a PB with a dead pixel and then saying it's not a real mechanical problem. If the pixel goes out in the first thirty days, try bringing it back and get the manager again. If you are super-nice, they might let you exchange it as your "one free exchange in the first thirty days due to mechanical problems"--even though Apple says dead pixels aren't really a mechanical problem, some store managers just want you out of their hair.
