View Full Version : Powerbook Problem

24th July 2005, 05:18 PM
Hi All,

I have recently purchased a PowerBook 15" SD,1GB,100GB,128MB and for the most part I have been very happy with it.

However I have been having some recurring problems which I am a little worried about.

When running on AC Power it runs perfectly however as seen here (http://users.tpg.com.au/cschembr/pbk1.jpg) however when unplugging and going to battery power the screen becomes like this (http://users.tpg.com.au/cschembr/pbk3.jpg) and this. (http://users.tpg.com.au/cschembr/pbk5.jpg) Then when you plug AC Power back in the screen goes to this (http://users.tpg.com.au/cschembr/pbk6.jpg)

I was wondering if anyone else has had a similar problem and if anyone knew what I could do to fix it.

An interesting note is that if you close the cover and reopen it - the problem seems to reset itself and continues to run normally - Not sure if this means much....

P.S Sorry pics not that good quality as taken with my Phone!

Have you run the apple hardware test CD that came with your powerbook - this may confirm where the problem is.
i am guessing its mostly lightly something to do with the video card / board and its associated bits.

Definate issues - Seen simliar results when overclocking video cards too far.
I'd give Apple a call & take it to your nearest service centre.

I doubt it would fix it but also try the latest video card drivers...

I've got the same issue and also a simular thing then I plug in the dvi...

I just need to find the time to get it to service.

Ran the full apple hardware test and it said it found nothing....

Like the first poster i found that closing and opening the lid would sort it out, and manually changing the res...

I also found this problem with my 15" Powerbook, also has the 128MB video card. Except it seemed to go away when I clicked my mouse, probably would go away if I closed the lid though. I posted this note on the forum here! (http://forums.appletalk.com.au/index.php?showtopic=8028&hl=)

I haven't taken it to get a service yet, I only got it at the end of May. Was happening as soon as I got it too. It doesn't bother me so much now, I just plug in when it's off.

Let me know if you find a solution to this problem, or find out what the problem is. I might have to take mine back to the store as well.

I reran the Apple Hardware Test and found nothing.

I think I'm going to have to take it back for service. I'll let you know how it goes.

Could be a dodgey batch of 9700's ?

Not sure if this is related but now the LCD display on my PowerBook is now flickering. Eventually it gets so bad it stays off and only way to turn it back on is to fully reduce brightness then fully increase it a number of times.

I ran the Apple Hardware Test again only to find no problem :unsure:

I am taking my 1.67 PB in for checkup this week some time, but recently i got to know one of the tech's in the Hobart apple shop and he said that he has seen a few 1.67 Raddy9700's with this prob... and also that the apple hardwar test does not adequetly test VRAM..

Will update when I get the word
