PowerPC :: Ibook Hardware - Goes Black Or Gets Small Lines Running
Jun 3, 2007
My friend gave me his ibook 900mzh that was not displaying because he did not know how to fix it so I took a stab at it. I am not new to fixing computers as it is my profession but I'm new to Apples. Anyway, the first time I turned on the laptop the lcd displayed without any problems, every time after that it turns on randomly. After taking it apart about 3 times for various reasons and mistakes the laptop now displays every time I turn it on, but if I apply any type of pressure to the lower left side if the laptop the screen either goes black or gets small lines running through it. From what I have learned the only possible conclusion that I could come up with is the magnet that tells the ibook if it is open or closed has something wrong with it. It feels almost as if whenever there is any pressure around the hard drive the screen goes black. Any ideas, or tests I could do to fully determine the problem?

I've got a friend with a 17" PowerBook G4 that's suddenly started displaying a vertical strip of black lines about 2" wide. Any idea what's causing the problem? I've seen plenty of pictures of PowerBooks with pixel-wide strips of a single color, but none that show black lines. Something else to note is that the problem area is displaying a shadow of the previous window that was there (ghosting).
He's tried all the usual, from rebooting to rubbing the problem area to pressing the metal strip above the keyboard to try and reseat the ribbon cable.

My brother's ibook (14", 1.33 Ghz, 1.25 GB RAM, 10.3.9) recently developed a problem: when he would open it, the screen would show fuzzy lines for a few seconds before "stabilizing." He tried to live with it, but it got progressively worse. Now, the lines never disappear, and the screen flickers as well.

I just bought an eMac from an appliance recycing center. It works great except for the lines running down the screen well it's kind of more like shaky. It's a G4 800 mhz I took it through the rain to my truck to get it home. But even then it didn't get too wet.

So tomorrow I'm going to be getting a Powerbook G4 from a friend. He says there are two problems with it.
1. The Graphics. I haven't seen it personally, but he says every time the laptop starts up, the display has a bunch of parallel vertical lines running down it. Is this a hardware issue, and is it easy to replace? Or can an update fix it? I wonder because isn't the integrated graphics mounted on the logic board?
2. The WiFi Card. I remember the day he got it, we both say the WiFi worked like a charm. One day, it pooped out on us. Now, the only way for internet is by ethernet. Did something possibly unhook from it, or is it a bad card? Once again, a possible update for it?
I won't know for certain until I get this laptop tomorrow. I will post updates when I can physically check it out.Also, this laptop is an older one, so no warranty or AppleCare on it. It is also running Leopard, but I doubt it is updated to the latest.

My wife has a three-year old iBook G4 and yesterday while she was doing some work, the screen just went black. By the time she brought it to me the machine was shut down. I hit the power button and it started to boot up, but about five seconds later it shut itself down again.
I kept playing with it and I was able to get back in to OS X and I played with it for a few minutes and all seemed fine. I then shut the screen and put it to sleep, then when I tried to wake it back up it shut itself down once again.
After a few more tries of getting it back in to the OS I was able to get all her files off the hard drive, but the problem is still there.
My guess is that it's the logic board, but that's just a guess.

Just bought a used ibook G4 from ebay for my sister and was giving it the once-over. did a software update and installed 10.5.3 (no backup first!). It installed ok, but after restarting it just sits on a black screen and goes nowhere. It plays the on chimes and churns the DVD drive, but then nothing. BTW, the computer didn't come with any installation discs

I was using my ibook just now, when suddenly, the screen went black, as if it were sleeping. I don't know if it was sleeping, but it would not wake up. I turned it off, and tried to turn it back on. But when it comes on, I just hear the fan. The apple logo does not light up. I'm not sure what's wrong.

A friend of mine has an ibook clamshell with black marks on the screen. He sent me a picture but I really can't tell if it is a broken screen or pixels or something else.

Can I run Mac OS 7 .5.3 on my iBook Clamshell? Am I providing enough info? If you need more info, I'll tell you. Right now I'm copying some files over to my hdd drive, getting ready to clear 68 something MB's off. I will then put Mac OS 7 in the root (almost). Will this power pc thing do it? It seems that it's like the old Macintosh's, just more powerful and better.

Everytime I turn it on I get a black box asking to shut down or restart the mac. I have managed to get it to turn on to powersave and managed to update the software. Thought it might help but just made it worse - it won't boot up at all now past an apple symbol with a little swirly thingy underneath (I apologise now for my lack of intelligence when it comes to computers/knowledge/names of things!) The first time I managed to boot the computer up it came up with the grey screen and a little folder flashing between a face and a question mark which I assume meant it couldn't find anything but that appears to have gone away now. I bought this computer new from Apple about 2 - 3 years ago and no disks were provided with it.

two days ago my iBook G4 decided that it no longer wanted to work. Basically it wont move passed the start up screen (the apple logo with the pinwheel underneath) but the problem that I am having that no one else seems to have is that my computer will shut back down after about 20 seconds of the load screen?

I have had my iBook for a good 4 years now. I have a 1.2ghz G4 ppc running Tiger and it is starting to run slow. I noticed that videos will now pause if something else is running or downloading. This never happened before. I was thinking about reinstalling my OS but would like to avoid that. Does anyone have this same problem or have any tricks to speed this up again?

I was recently given a (supposedly) non-functional iBook. I reinstalled Tiger on it, and it did fine through the installation and initial startup. However, everything runs really, really slow. It will work normally for about 5 seconds, and then slow to a crawl. Opening system preferences just took 5 minutes. The beach ball shows up with nearly every click.
Anyone know what this means? Bad ram? Bad HD? It is the 14" 1.42 ghz model with 756 mb ram.
Oh yeah, the reason it was presumed dead was because the previous owner smacked it on something, and the LCD screen is bashed up. The rest of it seems physically fine, but it was subject to some sort of impact.

My old clamshell iBook seems to be running very slow suddenly, I have to wait for typing to catch up with me and in this chatroom I go in, the chat screen keeps filling in and changing to same colour as background so I cant read what people have sent into room or and all buttons disappear until I run cursor over where they were!
It doesnt do this when I go in same room on iMac. It didnt used to do it on the iBook either! is it just getting old and needs replacing? Think mine was made in 2000, so is about 8 years old.
How do I do things like disk defragment or see how much hard drive and memory is been used? I wondered if it was maybe full?

Hi Everyone
I have an iBook G4 with 800MHz and 512 MB. I understand this is the max I can run this on. I really cannot afford a new one now and wondered if there was a way to increase the memory at all or get it to run faster. I deleted programs I do not use but it is still slow.

A friend of mine gave me her old iBook G4 so I can fix it. Something was wrong with it (half the applications are missing, spotlight reindexes every time it restarts etc). So I'm just gonna reinstall everything from the ground up. My question is though, should I install Tiger again or would Leopard be better? The only thing I am afraid of is that Leopard would slow down the iBook since it's an older Laptop. Here are the specs:
iBook G4 (PowerBook6,7)
CPU: 1.33GHz - PowerPC G4 (1.5)
512MB Ram
ATI Mobility Radeon 9550
40GB HDD

I recently bought myself an Xtra monitor to hook up to my Ibook. I also used the hack to be able to split up the monitors to have full resolution of my new monitor.
but now my computer is running slower. somewhere in this forum I have found out that because of the hack my Ibook now has to work extra hard to be able to run on 2 monitors.
my question is, isn't there a way to be able to use my new monitor at full resolution and just shut of the original Ibook monitor? so my Ibook does not have to split up his memory? If I mirror them I Can't work on full resolution ...
somebody doing this?
Or... What do I do/buy/download that my Ibook can work on 2 monitors, but doesn't run slower.

My iBook will not display anything on its screen. Rather, it just remains black. One time, the screen did come on, but then shortly after booting, it flickered a lot and then went black again. A year ago, something similiar happened and when I took it to be serviced (when I had AppleCare), they had to send it away and have a new logic board installed. Now this machine is out of warrenty and and I am not sure what to do, or even if it is the same problem. Any suggestions?? Thanks!

So today I noticed a small black bar on the corner of my screen. I tried to get a screen shot of it, but i couldn't, like it was off the screen. However, my mouse dissapears under it when i move it there.It is a little hard to distinguish because it is the 2.4 ghz macbook aluminum, glossy screen so it has the black surrounding it, but it is definably there. This all along the right hand edge of the screen.
Although there is a chance it may have always been there, I am not so sure. I think there are lines along the top and left hand sides, but they are much smaller. again it is hard to tell. I am fairly sure that there is none on the bottom of screen. Is this normal, or what? I have applecare, and I didn't do anything to my macbook. Although it is getting me a little OCDish, and is slightly annoying, and I know these things on the screen tend to expand.

Recently i've added a Panasonic CRT to my setup running dual screen on my iBook G4 (latest rev.) Just wondering if it's safe to run lid closed mode on it. I know that it's capable (even though it's not supposed to be.) Would i run into severe problems if I did this as far as screen damage? I'm not sure if the heat comes through the keyboard and would create pixel problems.

I just bought my macbook pro 13 inch about a 40 days ago and I have just noticed two small black dots on the on the bottom of the screen near the left side of my dock. I have done some research and they seem to be "dead pixels" They're really small but for the price I payed i didnt expect any problems. What are some suggestions to get rid of them or if i should contact tech support? Here are two pictures of the dots: They kinda change colour when i move my head around.. Not sure if theyre dead pixels or not.

As you can see from the video there is a strange black area surrounding my windows, but only when there are "active," not when I click on the desktop. The iTunes window is unaffected. Additionally the Quicksilver command interface and the Dashboard have a discoloration which is very annoying. Do you know what could be causing this? This behavior goes away when I restart my computer but eventually comes back. I have not been able to tie it to a specific app yet.
This is on a white macbook that I've had for almost two years, but this only about one month old. It didn't use to happen very often but nowadays it happens almost every day.

My MacBookPro 15" 5.3 worked fine until today, All the blacks (rgb 0,0,0) on the screen become red stripes.
When I boot into Linux or Windows the same problem appears, so it's probably a hardware problem.
I have no expensive adaptor to connect to an external lcd screen, so I don't know yet if the problem is in the mac screen or in the cabling or somewhere else...
Here are 2 screenshots of black squares a drawed in Illustrator, one taken on the mac (cmd + shift + 3)
one taken with a camera (where you can see the red lines)
I want to avoid the MacStore as I want to avoid missing my laptop for a month...
