PowerPC :: PowerBook No Longer Boots Up - Chimes, But No Screen
Oct 25, 2006
I recently got a cheap used 12 1.33 PB, that has worked great for a couple of months.Yesterday the PB shut off totally while in sleep mode. I couldn't power it back up at first, but was able to after I reset the PMU, and plugged the power cord in. The computer worked fine after that for the rest of the day.This morning, I noticed the PB shut off again during sleep mode. But this time, I can no longer boot it up. The PB chimes, but then nothing comes onscreen, and there's no hard drive activity (so I'm pretty sure its not the screen.)
It's a PowerBook G4, 15" model A1046, and this is what's going on.
Powers on, checks combo drive, gongs, no flickering or lighting on screen, period.
Tried a PRAM reset several times but it NEVER gongs a second time. I tried booting to Open Firmware and typing mac-boot, blind, but nothing. The keyboard clearly works, as the caps lock light works.
The hard drive spins up, the fans run at normal speeds, so everything else is clearly functional.
I have a second hand 12" PowerBook G4 that sometimes will not boot. It will sometimes chime and the LCD will stay black. Like I said this does not always happen. I have already tried to reset the PRAM and PMU and this does not seem to have any bearing on the machine.
I am trying to figure out why an iMAC does not boot properly. Model ECM 2133 Memory:1GB (only 1 module in one of the 2 available slots). Everytime I push the power button I only hear the chime sound and that's it. You can hear the HDD spinning but the screen is always black. I already did the SMU and PRAM reset and nothing changes.Keyboard is still unresponsive and the screen is black. Mouse light is responsive. I pluged the keyboard on another computer and it works fine. Sorry if I'm not doing something right but I am a newbie with MAC's
I took apart my IMac G3 today (2 times once to put in a new hard drive,and another forgetting to put a jumper inside) once I sealed it back up and put the powercable in, nothing, no chime, no noises, no light. I've took it apart another 3 times now looking for loose connections but there all in.
I know very very little about computer parts and things like that, but I hope to have provided enough information. When I boot up, both plugged into the power cord, and on battery, the powerbook will reach a white screen with an apple logo in the center. There also is a rotating disk below the apple logo. It will then shortly power down. I made a visit to the genius bar, and they told me something was wrong. I was like DUH!!! They said for $320 it would all be fixed, but I was hoping to be able to find out what was going wrong with it. Sadly I don't have the start-up disk that came with the laptop .
I've got a 1.5Ghz PB G4 (128MB Radeon 9700 model), and it would appear that the DVD burner is no longer being recognized. It's out of warranty. I've opened it up and verified that the cables are all connected. I know it is receiving power, because it spins up when I tell the computer to shut down. Symptoms: disc in the drive does not mount, eject key does nothing, Disc Burning in System Profiler says "No burning device was found. If you are using an external device please make sure that it is connected and powered properly.", disc in drive is not seen by Disk Utility, ATA in System Profiler only shows my hard drive.
My 1.67ghz, 15" high resolution, Powerbook seems to be broken. I use my laptop all day every day on battery power, and charge it through the night. Today, when I got home, it drew no charge from the adaptor. I have a backup iBook G3 which still charges perfectly off the same adapter, yet the Powerbook doesn't. I have left plugged in for about 45 minutes now, but still no charge, so the computer won't start up. I have a lot of important work on this computer, so I at least need some way of getting my data off it without ripping it apart to remove the HD. What should I do? I suspect that the power port in the laptop is somehow deformed, and thus is not making a connection. If this is the poblem, will it mean a new logic board?
PowerBook G4 Ti:Where can one look up the meaning of diagnostics codes? HDD diagnostics error code: ata1/6/3 HD:2,0 What does a single blinking LED on the battery mean? AppleCare does not show the HDD, chance it is ok but not connected? A friend's system wouldn't start up, he said I could take a look, asking me to recover some family photos from his Hard Disk Drive. This machine had not been used for months. So far I have uncovered two issues and would be grateful to receive further guidance here to get this machine up and going.
service history: 3/10/2005 = repaired directory errors, charged clock battery, installed optical drive. action: Remove PRAM battery and it powers up. I like to tinker, and I'm recently out of work, stumbled upon a place with step by step instructions to take apart at <http://homepage.mac.com/sysop/PhotoAlbum13.html>. Followed those steps and removed the persistent RAM (PRAM) battery, put it all back together ( except for a few screws, oops! ) and it powers up, and seems to be charging the battery as an LED lights up now. Took it apart again and checked Hard Disk Drive connections, appears ok. Put the PRAM battery back in ( battery shows: 616-0144-A, match to slide 35 ) and now the system boots ok. Maybe resetting the connections got things going, maybe the battery needed a kick, who knows............
I have an iBook G4 which was working fine. A week ago my little sister used the laptop and now I have the following problem:
a) The laptop boots because I get the boot chime, but the screen keeps black.
b) I connected an external monitor to check if the problem was the laptop monitor. When I start the computer, I get a gray screen (in the external monitor), but no apple icon () and cannot pass from this gray screen.
c) I noticed that the caps lock light was not turning on, so I accessed the open firmware (keeping hold the power button - getting a weird chime and a light flashing near the case button - power chime ) and I got the open firmware screen (still in the external monitor) and I noticed that the keyboard was not working also! I connected an external keyboard (usb) and I am able to type.
I know I won't be able to use it as a normal computer because of this weird problem. I was thinking to keep it as a "desktop" with the external monitor and the external keyboard. My questions in this case are:
a) Is it there any way I can boot from cd from open firmware? (I cannot do the "keep the 'C' key hold during start up" because my laptop keyboard does not work.
b) Because I get the open firmware console, could this be a OS problem? What I mean is that if I reinstall the OS, could I at least keep using this computer as a desktop?
When I try to boot my Mac G4 the light comes on the cd drive will open but nothing else happens. No chimes or screen image. I haven't used it for a couple of months but it was working then.
I restarted and nothing. Still dim. I can barely, barely see things like if I hit expose, I can see shifting rectangles.
Also, I've been having this issue where the keyboard mostly stopped working -- if I hit kjjh, it'll come up as 3443 or something. It's usually fixed with a restart.
I have it covered by a year of applecare until feb 24, 2007 -- but I haven't registered it yet. Should I register and then call apple or what?
This comes at a REALLY bad time. I have design projects coming up everywhere and of course, despite my $250 external hard drive, i haven't been backing things up because I'm an idiot.
Can I hook it up to a external monitor just to make a backup of my hard drive?
I just revived my 12" PowerBook and I just starting to notice how dim the screen has become. Even my iMac G3's CRT is much brighter than my PB. I really love this thing and don't want to stop using it, so I was thinking about options to fix the screen. What's the cheapest route? Can I replace only the backlight, or do I have to replace the screen? And where is the most reliable place to get a screen changed?
I have a G4 Powerbook 1.67 that I don't take anywhere. It just sits on an iCurve as a home computer. Never been dropped, damaged, looks as good as new.
That said, the screen sometimes gives me these red moving pixels which distorts the screen image a bit (pic attached). And lately the screen has been going out at times with lines across the screen, then intermittent blackouts.
I have a PowerBook G4 15" 1.5GHz. As far as I can remember, the screen had almost no "play" when I bought it and now has about 1.25in of "play" when you adjust the screen angle. A guy in my dorms has one and it adjusts very smoothly. Lets say I'm closing the screen to put it to sleep, the screen will come forward for about an inch before there is any resistance from the hinges. What should I do? I bought apple care so I'm guessing that might come in to play. Is this something I can fix or do I just take it to an Apple store?
I've got a 15in aluminium powerbook, a couple of years old. So far I've had nearly everything go wrong with it. replaced screen, knackered hd, ram port failiure, and a battery that lasts 10 minutes.
I recently replaced the harddrive, as the standard issue one packed up a few times. I followed the instructions on ifixit.com website. To my delight I actually managed to do it, and the pb worked well for a few weeks. Then suddenly, the screen froze and faded to white. So far I've tried everything -
Resetting the pmu. Resetting the pram and nvram. Opened it up to check I reconnected everything. and checked to see if the hd is still working starting it up from another computer, and it works fine. Everythings still there. Someone also said if you hold 'R' key down on start up it resets the lcd. BUT STILL BLANK!!!!!!!!!
The screen still seems to turn black after a little while, indicating the energy saver is still on. I'm thinking I may have dislodged an lcd connection or something?
i have a friend who has a powerbook g4 (black keyboard) that was sold to him for very cheap, unfortunately the screen was torn off the base of the computer. Its in perfect running condition but he cant take it anywhere because the screen needs to be supported against a wall as it cant stand on its own. Is there any inexpensive way to fix the screen and restick back to the base of the laptop and if the only way to go is get a professional to do it, how much would it cost him to get it fix. He got the computer for 50 bucks so having the computer work perfectly even if he has to spend at most 300 dollars would be great.
I've got an older 15" powerbook running Mac OS X 10.3.9 (i think). Lately my computer screen randomly turns itself off, the whole think going black, like it was asleep or off, but the computer keeps running just fine. Like i might have itunes playing or be burning a disc and that goes on just fine. The computer itself stays running. What I've been doing is putting the computer to sleep by closing the notebook, letting it rest for a few seconds and turning it back on by opening it back out. This fixes the problem for anywhere from 5 seconds to indefinitely, until it happens again. Lately its been happening more. The computer is 4 years old, but the model itself, probably 5.
I encountered a problem this evening with my Powerbook G4 15 inch Powerbook. When I was opening the Powerbook, awakening it from sleep it seemed there seemed to be an abnormally bright flash, then the screen went almost completely blank. Luckily, I was able to see enough to burn my docs to a disc in the event this was a serious problem. It seemed the rest of the laptop was fine.
When I restarted the computer, the screen appeared to be fine. I ran Onyx in the event it could clean anything up, and when it was running the screen appeared to go attempt to go to sleep again (although it was not set). Touching the trackpad immediately woke it up without a problem. After restarting after Onyx finished and using it for about a half hour I have not encountered the problem since.
Is this a sign of a failing LCD or possibly a bigger problem or just a harmless isolated event? Is it worth trekking over to the Applestore? I'm covered under Applecare.
in the last week i've been watching some awkward behavior from my powerbook g4 lcd screen. when i move the screen (rotate to close or open) the screen flicks. white horizontal pixel strips emerge on my screen, in a fractions of seconds. seems like a malfunction . i've never dropped my powerbook, so it could not be jammed by a fall. this started to happen with no reason that i could understand. my powerbook has 1 and half years. anyone with the same prob? i could use some help here.... i thought this could be a temporary problem but it has passed almost a week!
My PowerBook 1.67 was having a screen issue (ever-present but mobile black spot about the size of a dime). I sent it back Apple and tracked the repair process. According to their repair status updates, within an hour of receiving the PB on Tuesday, is was on its way back to me. I should receive it late today or tomorrow.
Was just wondering if anyone else had this issue in the past and if Apple just replaced the screen. If so, was it new or refurbished, and how can you tell. Any odds that I've been upgraded to a MBP?
I have a powerbook g4 15", and its the lower resolution model. I was wondering if it is possible to upgrade the current display in the computer to the one that was introduced later that year that was brighter and 960x1440
I've got a powerbook G4, but the screen's all messed up. I've got it going through an external monitor right now, and is it possible at all to completely remove the screen, and just use the bottom half as a desktop? I know I'd be losing the airport, but we have wired internet. Would I be losing anything else, and would this work?
With my Powerbook, whenever I shut the screen the computer goes to sleep. I was under the impression that (unlike the ibook) this is not supposed to happen? Is there a way to set the powerbook so that it only goes to sleep when i explicitly tell it to (i.e. the option in the Apple menu), so that for example when I shut the screen I can still have it hooked up to external speakers/TV/the network?
I bought the lcd to fix up my cracked screen macbook pro. I see how to separate the complete screen display from the base, but would you know how to open up the screen assembly so can get replace the lcd? I haven't started yet, so it would be great to get some advice from all of you experts.
