PowerPC :: My PowerBook G4 Has A Red Tint After Waking/starting It Up?
Mar 20, 2009
Like, when the gray screen turns on, it has a reddish hue. after a couple minutes, colors restore to normal.
then if my screensaver kicks in, and I wake it up, even immediately, I can see that reddish hue and watch it slowly transform into the proper color.
What does this mean? Does it mean that my bought-in-2004 1.33 ghz PowerBook G4 is dying of age? it's nto necessarily the computer itself, but the screen.
y'know how in school, when the overhead projector would start to look brownish? and then a few days/weeks later, *explosion* the bulb has burned out?
The machine I'm having trouble with is a Powerbook G4 17" 1.33GHz with 2GB RAM. This machine has been very well cared for. It's mostly been used as a backup machine of late. When I do need to take it out with me, it's transported in a InCase padded Napa leather case.I mostly use it plugged into AC, and when I have it plugged in for longer than 24h, I remove the battery.
It is running for the most part of the day when in use. And when it is in use, it rests on a Cooler Master fan cooler pad to help with the cooling. I just close the lid when I'm done with it. The only time that it is shutdown or rebooted is when an update or installation requires.
So recently I brought it along to a friend's place, and she borrowed the machine to browse the internet. Being unfamiliar with the sleep function, she shut it down. After this, I cannot get it to start up again. Some of the measures I've taken to try and revive it are:
1. Resetting the PMU (shift-ctrl-option-power, wait 5s, start).
2. Removing AC + battery and holding power for 10s.
3. Reseating the RAM (swapping slots, removing one stick at a time, replacing the RAM with the original 512MB stick).
After all this, I still get nothing. I mean nothing. No chime. No grey screen. No spinning gear. No latch light. No fan. No whirrl-clunk from SD. When I say nothing, I want you understand I'm getting absolutely nothing.
There is a weird thing though. The battery indicator (5 LEDs on bottom of the battery) work. The AC ring indicate fully charged (green ring) and charging (orange ring). With the AC ring indicating charging (orange ring), and I invoke the PMU reset, it momentarily turns green before resuming on orange.
I've tried looking high and low for anyone with remotely the same problem, and can't seem to find anything like this.As far as I can tell, I think it's either a logic board failure or a PRAM battery failure.
My 12 inch powerbook does not start up. Instead it loads to Darwin. I have an install disk from a 15 inch powerbook G4 and I would like to know if using this would work on my 12 inch powerbook G4?
I got my new 24" iMac ~2 weeks ago, and it's AMAZING compared to my MB... Except the fact that the computer will randomly wake up or start up in the middle of the night. The first night I had it home, it turned on 7 times! The next night, it did it once and I turned it off. It stayed off. The day after that, I turned it off when I went to bed. At 4 AM I hear "DONG!!!!!!!!" Ugh. I get up, and turn it off, only to have it start up at 5 AM. x_x I spent the next day looking for answers, I turned off wake for ethernet network something, and turned off screen sharing, quit all programs, and turned off the Airport card. Still, at 3 AM, it wakes me up. I turn put my jacket over it so I can get some sleep. I've been fighting it every night. I'm tired of it. Yesterday I reset the SMC and PRAM, and it still woke from sleep.
I recently replaced my internal hard drive in my 20" iMac and it worked beautifully for about a week.Then, suddenly it started making a horrible clicking noise upon startup or when waking up from sleep.It goes on for about 10 minutes and then eventually tapers off and quiets down.But it happens every time I start up the computer or when I wake it up after it's been asleep for a while.I don't seem to be having any other problems with the functionality of the computer.Everything is accessible and working OK on the computer.I am just worried because many years back when I had a PC the internal hard drive failed after I heard a similar clicking noise, although it's been going on for a few weeks on my Mac without worsening, and my PC hard drive failed within a couple of days of the start of the clicking.
Is it possible that this is a fan or some other internal mechanism that possibly got jarred or moved slightly when I replaced the hard drive?Or a bad hard drive?I don't really want to open up the computer all over again but at this point, I suppose I have to.I am just not sure what to look for when I do.urls...

My Powerbook G4 is not starting up. When I press the startup button, I get the white screen with the grey apple, but that's it. I don't get thr little revolving "wheel" that usually signifies the startup process is working.
Prior to this problem, it was taking a very long time to start up but eventually would start up.
I've tried holding down the option key while pressing the start button- this worked yesterday, but won't work today.
My laptop crashed and refuses to reboot. Ive tried all the keyboard shortcuts without success. I get as far as the white screen with apple logo and the spinning wheel but nothing else happens. When i booted up whilst holding Control V I got a black screen with writing but I did not really understand what it meant.
it started once when I installed xp. all went fine. I was installing some soft I needed. Now it doesn't want to start. will freeze with phrase like this , with difference of cekunds.
I have a 15'' iMac G4 with 800 MHZ processor and 768 mb ram. I woke it from sleep one day when suddenly everything had a violent pink tint to it. I had no idea what to do. I've replugged-in the video cable, messed with Colorsync, blew dust from the internal monitor port. I don't know what to do!!
17" Powerbook G4 not starting up (OS X 10.4.11). Powers on, to first login 'user' screen, after entering password, never loads, the 'spotlight' icon appears in the upper righthand corner, and the 'busy' wheel spins when the cursor is moved over it, else nothing. Tried 'X' on startup force OSX startup in vain.
Alu 24" 2.4ghz when they first came out with aluminum, got it at the store. since august 07 My imac had a small yellow tint, i noticed, when i got it and it was not worth anyhting screaming about, i also noticed it had bleeding issues ath the bottom and sides. I wanted to return it or trade but i was convinced out of it.
Now i noticed that from left to right their is a prominent yellow tint streaking it's way across and fading around the half way point.It is irritating and sad to see this display on this mac was ok, at first but it is geting slightly worse.I have apple care, can i trade this/replace it at an applestore, or would they need to fix it?
I am leaving for a week long trip and many parts of it will not be able to run the computer off of the powercord, which is a problem because I get about 40mins of wordprocessing use out of it when I run the battery alone. Can someone explain what the significance of these levels are for my Powerbook G4 15'' (Alm) 1.25GHz, namely the cycle count and full charge/remaining capacity?
It wont wake from sleep and after I reboot it, it wont even start. After the chime, the screen stays blank and the fans start roaring high after a few minutes. I brought it to the Genius Bar. They ran diagnostics on it and concluded that the problem is the 3rd party RAM. I then removed the RAM when I got home and it worked for a day. Now, the problem is back. I already reset the the VRAM and the SMU. I'll bring it back today to the Apple Store but I dont know if they will even entertain me this time as they didn't even charge me for running the hardware diagnostics last time.
I recently bought a second hand Powerbook G4 1.67. It came without a hard drive so i put a new drive in and installed Leopard on it. The problem, before I upgraded it to 10.5.7 sleep mode would work fine but since the upgrade after waking up from sleep only the mouse will work and the rest of the screen is frozen. Anyone else have this problem or know of a fix?
When the computer goes to sleep, either on its own or if i tell it to, when i wake it up, it does not recognize my mouse or keyboard. The goofy thing is, the mouse will wake it, but it still does not appear to have any input into the machine once OS X is up and running again.
Our eMac seems to be developing a green tint in the bottom right hand corner of its screen. I've done some quick searching online and it seems that a few people have suggested a cold boot so it runs the degaussing process on a startup.
I left the eMac off for about an hour, unplugged. It did the degauss once it was plugged back in and "seems" to have removed nearly all of the green tint.
There are a few threads on various forums when I search on Google about this issue but they have no conclusive reasons why this is happening.
Could my eMac be developing a fault at all? I'm not too sure if anything magnetic has been placed on our table near the eMac so this may be the reason.
I recently bought a firewire 800 dual 1.42 GHz G4 power mac, which didn't have a hard drive or memory. I bought some memory from OWC and I threw a hard drive in it. When I press the power button I hear the startup sound however there is no video on the monitor. I'm trying to figure out whether it's a bad motherboard, video card, or if it could possibly be something else like the power supply. I have reset the PMU to no avail. Does anyone have any suggestions on what I could do to figure out which component is bad?
My powerbook will not start up all the way. It suddenly went off yesterday and did not give any noticeable warning. I left it alone after trying to start it up several times. I tried again today and had the same problem. I will here the motor for a few seconds and then nothing. Also, it did come on twice, went off both times when titled the entire laptop up. So, if I tilt it at anytime it automatically shut off.
I have a G5 powerpc that is flashing a question mark. Whenever this has happened in my life with previous Macs i have pulled out my trusty install disc and fixed the problem, however i have lost the install disc.
I do have an intel MacBook Pro. Is there anyway i can wipe and install OSX on my PowerPC via my MacBook Pro without buying an OSX install disc?
Also, i had read that i could boot in safe mode by holding down shift but this has no effect. Does anyone know why?
I have an old G4, think its a powerMac, not sure. It was given to me. When i try to boot up, its loading up, but its stuck at "login window starting" screen.
Did a quick search and couldn't find anything. My HD in my powerbook and full and I can't seem to start up my powerbook because the hard drive is so full. Does anyone know a way to get the computer started up so I can free up some space in my hard drive? I also have an external HD if that is of any help.
I turned my iMac on today and it starts up to the blue screen with the welcome screen but the loading bar doesn't load at all and it just freezes. Nothing has changed between today and yesterday
I have a first generation iMac G5 and it come with 80GB of internal storage. The drive is so full that I rarely have more than 2 GB available. Even seeing 1 is becoming hard. I checked the size of all the areas of the computer and together all the files visible on the Macintosh HD only amount to about 61GB This leaves anywhere between 17-19GB (counting the way they measure GB) of space that is not accounted for. I understand there are hidden system files and other things that are not visible to the Finder, but this number seems outrageous. I was thinking of backing up my entire computer. Zeroing out the hardrive and reinstalling the OS and starting from scratch. If I wanted to do this maintaining the same documents files applications preferences and users.
I have a Powerbook G4 1.5 w/ 1GB of RAM and the stock 80GB HD. I've run this puppy pretty hard for a couple of years now, and it's lately started to lag a bit - perfectly natural. I was considering buying a new notebook but I've decided to wait until after Leopard comes. So my question is:
1) How do I determine the max RAM I can put in this machine? 2) Are there are specific specs I need to be concerned with when swapping out the Hard Drive? Any type, size limitations, speed limitations, etc.
I'd love a little input as to how I find out this info. I think instead of taking the notebook plunge now, I'm going to put a nice new hard drive in this one and possibly bump up the RAM a little more if it will take it.
So is the is Powerbook G4 802.11g or b? it is the 1.25GHz model. Also, one thing I don't understand regarding the airport extreme or any airport for that matter: isn't the maximum speed going to be completely determined by how much the cable provider, Comcast, pumps out?
If this is the case, how do I determine what my transfers and speeds are looking like specifically for Comcast? And, how would an airport extreme improve upon this or any other performance aspect in this regard?
Powerbook G4 (Ti-book) 667 mhz, 512 mb RAM. I finally after YEARS upgraded my OS (10.4.10), yay me! Just bought Adobe CS3 (for the new IMAC we have yet to buy), but I would like to install it on my Powerbook. SO, it it time to bump up to 1GB RAM. I was told it was tricky, and I should take it in to the apple store to install, but then I took a look under the keyboard, and it looks pretty simple. i have installed new RAM on a G5 tower, and this looks way easier. So, I am planning on buying the RAM either online or at FRY's, then installing it. BUT, I know I have to be careful of what type of RAM to buy. I found what I think will be good at [URL] but I will have to buy 2 (512's) as mine currently has 2 (256). I guess I just want to make sure I am not going about this the wrong way before I drop about $200 for RAM upgrade...
I have a 15' Powerbook G4 1.67, currently with 512 of ram....so i'm shopping for an upgrade, but not sure which specific type to go with. In my system profile it says i'm running..
Type: DDR SDRAM Speed: PC2700U-25330
And these are the types i've been seeing to choose from.
