PowerPC :: 17inch G4 1.5ghz - Brightness Stuck
Jan 3, 2008
For as long as I've owned my powerbook G4 1.5ghz 17-inch, the brightness has been stuck at a single setting. Both keyboard and menu changes function, and show that I've changed the brightness, but the brightness doesn't actually change. It even remembers what level I place it on, but obviously it doesn't matter since the brightness of the LCD doesn't actually change. I've done all the software updates and repaired my disk and permissions, and I've even tried resetting the PMU and PRAM(?) in the past, but to no avail. Now I'm wanting to sell the machine and have to replace the battery (since the display being bright has killed the battery over the years) and wanted to get this sorted as well.

Just wondering if its possible.. looking on one of the memory merchant sites it looks like only 1GB PC2700 DDR RAM modules are available.
I have 2x1GB sticks in it already. Is it possible to upgrade to 2x2GB's or is this not possible
Would appreciate any clarification on this.

My PowerBook G4 1.5Ghz won't boot up. It happened about a year ago when I first got my new MBP so I just let it sit. But I'd like to give it to a friend if I can get it to work. I've tried resetting the PMU by holding shift+control+option+power... waiting 5 seconds and powering on, but nothing happens. The battery appears to be functioning correctly. When the cable is in it lights up like normal and the battery indicators light up and are in full charge. I've taken the ram out and put it back in. Any other clues what I could try before bringing it in to Apple?

Our old powermac died recently (G5 2.5ghz x2), the cost to repair was quoted at 850$, which is roughly the same price as a new Mac-Mini 2.0ghz. Just wondering how the performance of new mini compares to the 4 year old powermac? A new powermac is out of the question right now.

I've been looking to upgrade the RAM and the hard drive in my powerbook g4 so I can prolong this little baby's life. I don't see the point in throwing something out that is still working. However, after a little scouting around online, I can only find 250gb drives advertised for Powerbook G4. Is this the case? Are there no 500gb drives that I could install too? Is there a specific type of drive I need?

So I just got the 'last gen' MacBook Pro - 17in and seemingly successfully migrated my old iMac G5 over using the Time Machine and Migration Assistant. Only problem is none of my photos or iTunes transferred over. Also it keeps telling me my registration number is wrong on FCE, even though I've entered it correctly...
Info:
MacBook Pro, Mac OS X (10.7.2)

I was wondering if/where I could get a better screen for my 12.1" Powerbook... Better viewing angle, brighter, possibly glossy. OR is there a way to bump up the screen brightness by just putting more juice in it? I know it would hurt battery life, but while it's plugged in it wouldn't hurt.

Does anybody know if Apple is going to bring the new silver bezel with matte screen to the regular Macbooks like they did with the new 17" MBP? I would buy in a second if they would!

Up until recently, F1 - F5 have been Brightness and Volume controls, as they have been since I got the thing. I go to use the Volume, and it doesn't work. I then try the Brightness, and it doesn't work. F6 - F12 all work just fine, which leads me to believe that iBook had a brain fart.
My volume balance has always altered itself. Balancing itself out of one speaker left or right as it so chooses. I know it's smart, but now it's just screwing with me. Settings go and change on their own, dock icons have switched, but this one has stumped me. How do I get those hardware function keys back to doing what they're there to do?
Also, I tried it with an App called Rowmote, that lets you control your Mac from your iPhone, with Apple Remote-like control, and the volume won't change using that either. Another symptom is that sometimes it makes clicking sounds, as if it were changing slowly and glitchy (which it did click sometimes anyhow) when using the Volume slider in the menu bar.
No, the options in System Preferences is not checked to use them as FN. Any ideas?

The brightness goes up when you plug in your MBA, but then over time it just goes up and up. I honestly like my brightness pretty low (rarely more than half, typically at 3-5 notches), but it just keeps on going up and up. I almost never set it above half, but multiple times a day, I notice that it looks pretty high and it's at like 3/4 so I put it it down to about 1/3, but after a while, it's just up again.
Anyone else notice this? What is it, why does it do this? How can I fix it? I don't mind not having auto-brightness (even though I loved it), as long as my screen doesn't keep going up.

I picked up this G4 (M6498, 17", 800/256/80HD) from a lady in her 80's whose son sent her a new G5, but I'm having trouble getting it to boot on HD or CD. When I turn it on all I get is a file icon alternating between mac face and "?". Boot from IMAC CD: same thing - I hear the CD track switching a few times periodically but that's it. Boot from OS9 Install CD: same thing. I'm not that familiar with iMac, although I've had a few other Mac machines on and off through the years AppleIIe, PowerMacG3). Any suggestions what to try next?

My G3 keeps repeatedly rebooting. It goes through the loading process, but when it comes time to give you the desktop, it shuts down and restarts all over againl. As it boots up, a double image that you can't read comes up on the monitor, along with a solid color bar that separates the desktop image in two. I have two internal harddrives and changed it to reboot from the second harddrive, thinking that might be the problem. Immediately after doing this, it rebooted fine one time, but now is caught in the reboot loop again. When I startup from the install disk, the image is fine on the screen, as is the startup itself and when I run disk doctor, it says both drives are fine. I homeschool and would like to keep using all of the classic educational software on it for my 5 year old. It's running 9.2.2, 256mb memory 9gig drive is current booting drive, other one is 2gig.

I have dual ACD's. How do I make it so that both screens have the same brightness? If I adjust the brightness in the display settings it adjusts the main screen, but then not the other one. How do I make them the same?

I just got an iBook g3 used, it had 800mhz, 256 megs of ram, 30 gig, and had osx 10.3.9. I am new to macs, but I particularly wanted an IBook, and I found it used at a good price. I downloaded some software (acquisition) and moved some files over via usb keyboard from a pc. Suddenly, it froze while stuck in screensaver, and I turned the power off. Now, it just stays on a gray screen when booting, and eventually goes black for a second, then reflashes a gray screen. No mouse, no cursor. What do I do?

Well as the title says, my latch button on my 12" powerbook g4 1.33 is stuck in, and i have no idea how to get this thing fixed. It all started with a trip to the apple store to get my optical drive replaced because it was "eating" DVDs. When they sent it back to me, the report said they had replaced the bottom case, and within a week the button would get stuck in a crooked position so that the latch does not catch. I couldnt afford to give it to apple for another week because spring break was now over, so i just dealt with it until yesterday when i hauled it back to the apple store.
The genius there was like "ha! thats strange" and filled out the paperwork, and then can't get it to show up as a free fix because they won't replace lowercases without it being user repair. The head genius then came over, i explained my problem, and he said there was nothing he could do to help me, and then they walked over to the next customer.

after my six year old daughter dropped it(on hardwood floor).
I tried this:
<command> <opt> <p> <r> Letting it chime 4 times. But, no luck - it just sits there witht the gray screen/dark gray apple logo and that thing twirling around like it's thinking.
check that I've left it on and it has now worked its way to the blue screen. Cursor shows up and the twirling thing is gone(as are the little clicking noises inside like it's actually trying to do someting).
Now you're really going to let me have it. I don't have any of my original disks.
Guess I should take it to the Apple store and see what they say(no applecare).
I was running Tiger(latest version) and the ibook G4 is a 1.33 with 768mb of ram if that matters.
Luckily all my photo's and music are on my powerbook and mac mini.

Today i powered up my iBook G4, after a long time of waiting for the blue bar on the start up screen to reach the end, it became stuck once it had reached the end, i left it for a hour or so on this screen, and it hasn't got past it, i did a hardware test, and everything is fine, although it took about 8 minutes to complete the 'memory' test, so i'm thinking it could be a RAM problem ?, what do you guys think ?
EDIT: Just used disk utility and apparently there is a problem with the disk, that it can't fix, so i'm gonna have to reinstall OSX

I recently have recieved an ibook with osx 10.3.9 that doesnt have any wireless internet. Since i have a wireless adapter, i decided to install it on so i can use this computer for internet. Since the driver for the installer is only for newer osx versions i decided to upgrade my os. I knew that my cd-rw/dvd-rom drive isnt working so i booted disk1 of the cd-installation from my old ipod. Now it wants disk 2 and when i put in my ipod with the second disk it wont continue installation.

As I wait for my Apple Extreme Base Station, I was wondering if it would make sense to create two different SSID networks. One Mixed b/g for 2.4GHz devices and another one solely for 5GHz. I know my ATV2 supports 802.11n in 5GHz. As I go down my list of devices in my house, I can't tell if my MacBook Pros support the 5GHz. Both MacBook Pros are Mid 2010 models.
The reason for creating two different networks is that the AEBS downgrades your network based on the lowest device (i.e. b/g would be forced on a n device if such device connects to your network).

I have a 12" PB and latelly became a nightmare with the stuck CDs. Usually it does not want to eject CDs/DVDs from companies but it handles fine virging cds/dvds. ?? Probably there is some formating in the industrial kind of CDs outside, who knows.just want to open this thread for people with the same problem.If the drive tries to eject but can't and end up mounting the CD again. Just take another CD and when you press eject again push that CD into the slot but just one third and you will see the stuck CD coming out with no problem as well.It seems there is a sensor or something that obviously does not work well. I inserted a virgin CD and the drive worked just fine and ejected later on, but a CD as the installer for my Linksys get stuck and some other softwares too.

When I press the power button on my eMac, it takes extra long on the gray screen with the Apple logo and the spinning gif, then takes about two minutes on the blue screen with just the spinning gif, then goes to a solid blue background, with a functional cursor, but no OSX. I've tried trying to eject the CD tray at all points in the startup process to put in the Mac OSX re-install discs, but it doesn't respond. What should I try before sending it in to an Apple store or Cupertino?

I software updated my iMac g5 (powerPC 1.6 OR 1.9GHz), with the mac OSX updated(170mb), and it never fully completed the download, said it had problems with the package. So I restarted it, and now its just stuck on the blue screen with the grey box (where it loads the IP extension, etc).

I am a high school teacher and in my lab, for the first time, I have an eMac (1 GHz G4), that, when I turn it on, all that shows is a grey screen with an apple in the middle. I tried doing a "mac-boot" to no avail.

I have had this issue for a while. No matter what I try, Flash movies are SLOW on my 1.5GHz PowerBook G4. I have 1.5GB of RAM, Leopard, and the latest Flash (Flash 9). Every video and game that I run in Flash is choppy unless I set the quality to "low". This occurs in Safari, Camino, and the standalone Flash Player application itself.
