PowerPC :: Holding Down Power-button While IBook Is Off?

Nov 17, 2008

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?

PowerPC :: Chime Sounded For Few Seconds On Holding Power Button

Sep 20, 2008

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.

PowerPC :: IBook G4 - When I Press Power Button, Power Fan Comes On, But No Picture Shows

Feb 10, 2008

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.

MacBook Pro :: Does Not Shutdown Even When Holding Power Button

May 7, 2012

Today I started to watch a video from a news site (probably using flash) and the computer started to slow down very much so I thought firefox had crashed. Then I force quit it and waited about a minute or two hoping the computer would get fast again as usual but it did'nt happen, so I tried to log out and nothing happened and then I tried to shut it down by clicking the power button and clicking in shut down.

Right after that, the computer started to shut down or log off (it was still very slow) and something happened it stopped in the middle of the process and displayed a blue screen (the same colour that appears when you connect another monitor to the mac). Then I thought of using my last resource: holding down the power button until the computer turned off but again, nothing happened.

MacBook Pro, Mac OS X (10.7.3)

PowerPC :: Advantages To Holding On To IBook G4

Jun 15, 2008

I was planning on selling my iBook G4 to assist in buying a refurb MB, but might there be any advantages to hanging on to it? The only thing I can think of is as an additional backup, but as it is only 60 GB, doesn't seem worth it. Book G4, 1.33, 640MB, 60 GB. Any creative uses for it or is it best to sell?

PowerPC :: Turns Itself Off - Emits High Pitch Squeal From Machine While Holding Button

Sep 28, 2009

When I turn it on it runs fine for sometimes about a minute (sometimes less) before it just turns itself off! After it turns itself off I'll hit the power button and it emits a high pitch squeal from the machine whilst holding the button. If I then remove the battery from the Machine depending on how long I leave the battery out and put it back in, it will then power up for a short amount of time. Sometimes I can get it to the desktop and open System Profiler for example, other times it gets as far as the Apple grey screen. I've ordered a power adaptor as I didn't get one with the machine but as far as the battery indicator goes, it's on 96% and all four green lights are on the battery indicator on the base. Has anyone heard of any problems like this before?I believe it's running a 500mhz processor and has 512mb of Ram.

PowerPC :: Making Power Button Shut Power Mac Off?

Oct 7, 2006

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.

PowerPC :: Removing An EMacs Power Button?

Oct 30, 2008

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.

PowerPC :: G4 Not Booting - Hold Power Button And Restart Computer

Jun 3, 2009

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.

PowerPC :: G5 Won't Turn On ... Blinking Power Button / White Light Every 4 Seconds

Jul 21, 2009

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?

PowerPC :: EMac Logic Board - Missing Power Button Connector

Apr 2, 2010

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.

PowerPC :: Power Button Cord Connector Broken Off EMac Logic Board?

Nov 28, 2009

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?

PowerPC :: Hitting The Power Button On The Unit Or Keyboard, The Units Screen Makes A Noise?

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?

PowerPC :: How To Fix IBook Power Adaptor?

Dec 22, 2007

I thought I'd write this brief how-to incase anybody else ever needed the information. I have bought 3 power cords/connectors/adaptors for my iBook in the last three years - crazy, right? I stepped on the tip of the first one by accident, and was unable to bend in back into shape. The second one (a third party version by MacAlley) spontaneously conked on me, the brick stopped worked. And more recently my third, another third party bought cheap off eBay because I was fed up of paying, developed a connection issue somewhere in the wire (it worked fine, then I had to fiddle with the wire to get it to work, then it stopped working). With all these broken connectors sitting around, I figured there must be a way to solder them together and avoid paying another 30$ on eBay and being without a laptop for 2 weeks.

Assemble all the broken adaptors you have, asses what works with what.
- I took the brick from the original which was working fine and the tip from the 2nd cord (the one where the brick stopped working)

Cut off the tip from both cords, make sure to leave plenty of wire attached to the brick and tip your using.

Strip the tips of both wires, there should be two sections; an outside section (wrapped around the inside section) and an inside section. In the original Apple adaptor, the outside section was braided around the inside (which was incased in rubber) along with a yellow insulator. In the second adaptor (MacAlley) the outside was twisted around the separate inside wire.

Clearly seperate the two sections of wire from each, then twist them together. MAKE SURE THEY TWO SECTIONS (INSIDE VS. OUTSIDE) ARE NOT TOUCHING. You don't want to short-circuit your adaptor.

STEP FIVE (optional):
Solder the wires together

Tie a knot in the power chord before the connection, to avoid accidental stress on the joint, and cover it all with electrical tape.

So far, its been working fine. But be warned, THERE IS SOME RISK INVOLVED WITH THIS PROCEDURE. My battery is charging fine and the iBook is powered as usual. I'm just waiting for the battery to fully charge to make sure the power adaptor stops charging the battery when its full (don't want a cooked battery!)

PowerPC :: Power Outage And Now Ibook Won't Start?

Oct 2, 2006

I'm currently out of the country doing field research and just the other night, there was a power outage here and now my ibook won't start up. Of course, being in a "third world" country, I wasn't able to invest in a good power surage protector.

Is my computer dead for good?

I have a lot of work that needs to be done and my computer is essential here. Anyway, I can rescue my computer? I press the power button and it does absolutely nothing.

What do you people think might be the problem and how much am I looking at to fix this?

PowerPC :: IBook Will Not Draw Power From Battery?

Aug 3, 2007

I have an 14" iBook, 1.07 GHz and it won't use battery power. As soon as I unplug it it turns off. It worked fine until I opened it up and swapped in a DVD-RW and a new hard drive (the old one was failing). In the power section of system profiler it shows 98 load cycles and about a 75% remaining capacity. It may or may not be charging - I can't tell. The battery says it's fully charged at 95% and I have no way to drain it and see if it will recharge because the computer won't drink from the battery. I had another 14" iBook battery laying around that I thought worked, but now when I put it in this computer it just sits at 0% then eventually says the battery is dead (the menu icon shows an X through it).

PowerPC :: Can Use My Ibook Dvd Drive To Install Apps Onto My G4 Power Mac

Jan 27, 2007

I have a g3 dual usb ibook that has a DVD/CD drive, 640 ram and a firewire port. I just bought a G4 800 mhz tower that has a gig of ram, but it does not have DVD drive (it's a cdrw only). My Ilife install disk is a DVD, is there anyway to use the DVD drive on my ibook to install software onto the G4 tower? Both devices have firewire but if possible I would like to use an ethernet cable connection between the two. I dont have the correct firewire cable(it's expensive).

A second question is i an os 10.3 on my ibook and 10.4 on my G4 tower. Is there a easy way to transfer all my files, settings, ect... from the ibook to the G4 tower? I don have the osx 10.4 install discs either (if that matters).

PowerPC :: Light Goes Out And Ibook Switches To Battery Power

Apr 2, 2007

I have an ibook G4 (2years old, a part of the battery swap program) that charges normally... for about twenty minutes. Then the light around the charger turns from it's normal "i'm charging" orange to nothing, the light goes out and the ibook switches to battery power. I've just inspected the power chord and there are no strains or tears, the plug at both ends are in good condition and the ibook power socket is fine too.

I've turned the ibook off for a period of time (two days) and reset the power manager... still no difference. The ibook looks and acts just like it should until about twenty minutes into the charge then the light turns off and it's like it's been disconnected. The chord is in correctly, i've even tried the apple extension chord = no joy. If i reconnect the power chord at the wall it's fine, starts charging again... and yes i've tried different sockets on different circuits in the house!

PowerPC :: IBook G4 - Fixing Power Cable Connector?

Jan 4, 2008

This is quite an interesting situation I'm in.

Today during High School, my first period, I noticed a Mac iBook G4 in the recycle pile used by my schools Tech department. I decided to swoop it up and give it a whirl, and see for myself what the problem with it was.

When I first powered it on, I was receiving a scrambled signal on my display. It was merely a white screen with lines in it, after a while of tinkering, even grabbing a few mac knowledgeable buddies of mine to see if they could do anything. It seemed like this would drag on, and I would not fix it.

In the end, we ended up tapping the screen and seeing a faint hope of light, that light was the appearance of the desktop! Unfortunately, the screen soon vanished back into it's scrambled state. Upon further tapping, we could only figure it was a problem with the connection of the display to the logic board.

This says the power cord is soldered to the board: [URL] I can leave the top case connected by the power switch cord if required. Perhaps I could tape the case down during work on the back side and rotate the connected case left during work on the front side. This is slightly beyond my skill level. Great advice found here during searches. I plan to be very slow, methodical, and conscious of screws/step.
