I was just wondering if anyone knows how I can remove my eMacs power button, the one that you press to turn the computer on. I kinda wrecked mine and I want to "pop" it out to have a look at it. Looking at replacement costs they are like 50 bucks so I need to try what I can before I fork out for a new one.
I have a iBook G4 laptop and there seems to be something very wrong with it. It started a few days ago just randomly. I was reading something on the internet and the screen went black on me, but the power was still on (I clicked CAPS LOCK to see if there was power). I then proceeded to push the power button and the power went off. When I pressed the power button again to turn it on, it made that internal noise it always makes and then the fan came on, and wouldn't turn off. There was no picture on the screen at all. Completely dead. But there was power, because when I clicked on the CAPS LOCK, the light came on). I tried pressing on the power button for at least 15 seconds and even went as long as a minute, and the power didn't go off.
I'm using a B&W Power Mac G3 with 512MB RAM and OS X Tiger for a SMB file server (with 5 users) and a USB printer server. Everything is working good, but I have a problem.
It doesn't have a monitor or keyboard/mouse attached normally (I can configure it via VNC). The problem is that I would like to be able to turn the machine off when it's not needed (like at night sometimes, days when I won't be home, etc.). I would like to just hit the power button and have it turn off, however it puts it to sleep instead.
Normally, sleep would be fine, except on the B&W, the fans still run, just the HDs shut off, so it's still noisy as heck.
Is there a way to make the power button shut it off? If not, any other easy methods of shutting it off you can think of? Via VNC won't cut it, as my dad needs to be able to turn it on (not a problem) or off as well.
I recently bought a couple dozen eMacs at a school auction. I've got about 5 that are sellable but some are being a pain in the ass. All the eMacs have a version of 10.4 on their HD, but with school programs (which they were supposed to delete). So I decided to do an erase and install of 10.4.
Well, so far, about 5 eMacs have been freezing on me halfway through the install, at the start of disk 2 of 4. What will happen is the eMac will restart after Disk 1's install then ask for Disk 2. I'll put Disk 2 in and it will install 5% of the way then the computer will freeze up. The screen will show some random horizontal pixels like the video got messed up.
All the eMacs I've done installs on have at least 512 MB of RAM. The install disks are not scratched and work perfectly on other eMacs. This will just happen to a certain few. And they happen to be my best ones (>1 Ghz processors).
I know I can get the bulk of it here: [URL:..] But is there a controller board? I can't find any documentation on this thing. I want to use it for a PC. Making an acrylic top is no problem. Just looking for pin-outs, dimensions, and maybe some pictures of someone else dissecting one.
This is a mystery to me. Long story but the gist of it is that I found if I hold down the power-button on my iBook while it's off it goes into some weird mode. i.e. fan spins, disc spins, sleep light flashes and a tone comes from the speakers.Is this some sort of hardware test mode? Is it going to blow up? Is it resetting something?
I have a 17" G4 1Ghz iMac, we used it until 10 months ago when I got my new 24" Intel 2GHz machine. That new 24" iMac is now in the basement craftroom as the digital hub for pictures/video/etc., while I brought the 17" G4 1Ghz iMac out from my closet for the upstairs loft general web surfing machine. It worked for 2 days and upon shut down would not re-start. I could only hear the fan and nothing else. If I held the power button for 10 seconds upon trying to start up there was a chime that sounded for a few seconds. Once the fan is making small sound, nothing else, if I hold power button for 5-20 seconds the computer will shut down (fan turn off).
Did some online checking, found article on PMU, so I did try and re-set PMU via the apple support article.Resetting the iMac (Flat Panel) Power Management Unit (PMU). Still, no re-start. It was running the latest 10.4.x update upon being put away for 10 months. Here is a picture of the bottom, the red light is on upon trying power on, my finger is on the PMU reset button. Is there any other diagnostic thing I can do? Is there a battery on this logic board that I can check/replace? I'm 100% ok at taking it apart and trying anything to fix it.
Got a tricky one here: powerbook G4, 1.25ghz, 1GB RAM (2x512), 80gb HD, APX, 15" LCD, serviceable battery, SuperDrive, OS: 10.4.11. It was brought to me with a boot problem: Computer turns on, gives the start up sound, backlight comes on, apple logo shows, spinner spins... then you get the dimmed screen, large option icon and "You must hold the power button and restart your computer": a kernel panic. I've seen this a few times before and the last time, I fixed it with a new hard drive and the removal of RAM from a bad ram slot.
What I did was: 1) Replaced existing 80GB HD with a backup 30GB drive. Then booted with a Tiger CD (the computer won't start with my disk warrior cd, nor with a tiger DVD). I was able to install Tiger and restart the computer. But the airport card doesn't show up. I tried a known good airport extreme card and this too has not shown up. 2) I hooked up the 80GB drive to my PC via MacDisk and checked it. Sure 'nuf it had loads of problems. MacDisk went through and fixed it (I'm not sure what the problems were as I'm new to MacDisk and don't know what it's looking for and fixing when it does). 3) With the computer running the 30GB known good HD, I started having the same kernel panics so I removed the first RAM chip (512MB) and tried to reset the PRAM.... here's where it went wonky. (I know, only change one thing at a time...) 4) As I said I tried to reset the PRAM (Option, Command, P, R, at start up). While I can get the computer to not boot, it won't restart. I don't know if this is just unique to this machine. Next I tried to reset the NVRAM and again got nothing. The screen wouldn't come on at all. After about three or four resets, the computer did start in Open Firmware mode. I reset the NVRAM from there and restarted (reset-nvram, reset-all). Still nothing on restart. 5) After trying to start it 15 times like this, I swapped the bottom RAM card to the top slot and removed the airport card (again, I'm stupidly trying to change two things at a time). BAM, computer boots... I put back in the 80GB drive that's been "fixed" by MacDrive and BAM, that boots fine too.
So then I put back in the airport card and it will boot, but won't recognize the airport card. I've re-seated it about a dozen times and have used terminal cleaner on the card and on the socket for the ribbon cable from the card slot to the logic board. As it sits, I can't get the airport card (either of the two) to show up at all. I did realize that the open firmware did reference a problem, but I forget the code now and when I looked it up, the references were to a failure of the airport card, but there were also more general references, so I can't be sure.
I'm thinking now that it's the airport card controller on the logic board, the bottom RAM slot and a corruption of the hard drive. Yes, there was a history of moisture into the device and I think a drop in it's past too. I'm the Mac repair technician for the people at the local bike shop, so I get to trade my repair work for their bike repair work. The problem is that they ride their laptops like their bikes, hard and greasy. I'm really wondering about ways to get the airport card back up and running. Or, baring that, a good card-based wireless adapter that I can slide in.
I have a G5 dual 1.8 power PC...Bought some ram put it in & booted up. Then a red light came on the logic board behind the power button. The machine wouldn't turn on....I called apple care & we rearranged the ram, now the red light is gone but my system still won't boot up. The white power light blinks every few seconds... the apple store told me sorry can't help because your machine is vintage. Even if my logic board is fried is there a place to buy one on the cheap?
I just bought a new Logic Board for a 1.25Ghz eMac and I've put almost everything back together after installing it until I ran into a problem. The power button cable that runs from the power button on the casing into the logic board has no connector on the Logic Board itself, now I have an old logic board that whilst being broken has a connector on it but I really don't want to have to solder the connector on for fear of breaking the logic board.
I was attempting to replace the hard drive in my eMac, but for instructions I HAD to follow some darn take-apart guide that said pull out the connection for the power button cord from the logic board. I didn't know that it was SOLDERED in there, and now I can't complete putting my eMac back together without doing so.
Can this be fixed without having to send it to Apple? Does it HAVE to inolve soldering, or is there an alternative? Is there a way I can temporary have my eMac power on until I get the connector fixed?
First of all, Noob imac owner here. I was just handed down an old imac g3 400mhz desktop that doesn't power at all.When hitting the power button on the unit or keyboard, the units screen makes a noise. No hard drive or green light comes on at all. At dead silence in the room, i can hear the screen flicker, like a tv would come on. I went to go about and read a few problems before, replaced the battery and even tried a new power cord. Any Ideas?
Last night a friend of mine spilt a very small amount of soda onto my macbook. I immediately wiped it off and powered down the computer. Today, when I turned the computer back on, everything works fine, however, a few of the keys are sticky (the space bar, arrow keys, shift button, and 2 others). Is there anyway to remove these keys to try to clean them? This is the current generation Macbook.
I added 2 sticks of 512 to my power mac g5 1.6. I had ahard time getting the computer to see the new ram, but finally was able to kinda get it working after zapping the pram. However my computer only saw these 2 sticks as 256, odd. So i attempted to troubleshoot the problem. I tried just installing the new ram, but the computer wouldnt boot. I tried a few different combos with the other 4 sticks i had, but nothing. I put the old memory back in, and still nothing. The power led looks to blink once every five seconds or so. I tried pressing the pmu reset button, but still the same out come. I also tried taking out the battery, nothing.
I had a weird issue this morning. I started computer and it did not make the chime sound, it didn't do anything at all. I disconnected it from the extension cord as well as all the peripherals attached to it and nothing. I tried a different start up disk and again there wasn't a sound. Then i unplugged it and reset the SMU on the mother board and air sprayed the computer to remove all dust. Then plugged it back and it came back on.

I have just shipped my Mac Mini to its new home and I've had reports that the panic error is appearing on boot up: "You need to restart your computer. Hold down the power button for several seconds or press the Restart Button." This screen appears on the blue window just after the grey apple screen has disappeared and does not get as far as the desktop at the same point each time. We have tried to reinstall mac OS from the original install disk but holding the "C" Key or the "Option" Key down on restart doesn't boot from disc. Is there a way you can view the Kernel Panic log before you boot into Mac OS so we can try and pin point the source of this problem. I'm wondering if this could have been the result of the shipping that has caused some hardware to come loose.
I still use this old PowerMac G4 (hopefully Apple builds a new MacPro soon!) and when not using it, it is in sleep mode.Unfortunately my cats like to touch the keyboard, thus waking up my Mac.Is it possible to wake the mac only by pressing the power button?
I am going to have to put the install disk in, however at the moment I have the apple care cd in the mac - but the eject button on the keyboard does nothing - is there another way I can get the disk out? I just get stuck on the 'flashing question mark' stage.
Need to remove a firmware password on a G5 2.7 Powermac bought on ebay.Have removed half of the ram and tried to reset pram no help. Removed battery, no help.Former owner forgot password, never logged out.
I am not very techie so please accept apologies for a naive question.
I am getting delivery of my new macbook pro today. I have already received advice on how to transfer all my software and data over (thanks). Once done I will be selling my Powerbook.
Is it ok just to remove my personal data? Or do i need to do a complete reinstall?
If i need to do a complete reinstall i have a question. I cant remember where ive put my original discs but ive bought some which are original panther install to a powerbook. My powerbook runs on Tiger (ibought the upgrade discs last year but have put them with the originals no idea where!!). So do i just put in the powerbook install discs that i have just bought which will be for panther or can i just remove my data?
Can anyone explain to me how to remove keys on a powerbook 15 aluminum? i spilled a few drops of gatorade on the computer the other night and now the spacebar is sticky .. i think removing it and cleaning underneath will do the trick, but i'm terrified to break the keys by prying them off.. i've been searching the internet for about an hour and can't come up with anything
Tonight, I might have a chance to get a G5 processor from a friend, who wants to dissassemble his iMac G5 and sell it for parts (he's going to buy a 24" iMac C2D). Should I replace the G4 processor in my iBook G4 with a G5?.
I really want to do this and show off with this (if successful) in the public.
I've been given a half torn apart iMac G3 700mhz (which still runs), and plan on putting it's bare essential parts into a case I'm making. I've taken out the drives and logic board with down converter, but now I'm stuck behind the CRT. I know it's very dangerous, but I need to get around it to get to the board underneath it. Do I have to discharge the CRT or could I just snip the suction cable connected to it without any risk? I plan on recycling the thing, but right now I just need it out of my way.
