I installed a larger hard Drive (100 GB) on my Apple ibook G4. Everything went smoothly until I tried to reinstall the disks that came with my computer (OSX 10.3). I put in the first disk and it runs fine until it comes to the part on "where to install" and the options button is supposed to light up. It does not so I can not get any further.

I recently bought a G5 2 x 2.7 for a real cheap price (70 euros, yes its true) as the owner told me that the motherboard was bad and had the three lights problem and won´t boot Then I started reading about this problem (micro-fracture) and tried to find a solution for it. First I tried was the "hair-dryer", it worked but as soon as the motherboard got colder then it hanged as the ram problem came back. I was considering the "oven trick" but seemed too risky and also a lot of work to unassembly it, etc...Â
I bougth a heat gun for 16 euros (Leroy Merlin). It is able to heat up to 500 Celsius and had two modes. I assumed the low mode may be around 200 celsius or so. Then opened the powermac, and started heating the rectangle area between the two memory banks. Slowly, moving it around, heating (not over the ram, just in the middle area). A few times I turned the max power for the heat gun as my intention was to "melt' the micro-fracture.Â

My MacBook Pro power adapter lights up orange even though it is not plugged into a device. When I do plug it into my laptop it remains the same and does not charge. Due to this my laptop is now dead.
What does this orange light mean?

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 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'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 just got my new imac 2 days ago. I was wondering is there another to turn on the power without pressing the power from button? (cuz i remember u can power on from the keyboard b4)
View 7 Replies View RelatedI 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.

Starting today my Powermac has shut off suddenly a few times in ~15-20 minute intervals. When I have many applications open simultaneously the computer is especially prone to this.
I have never had this happen before in the 3+ years of using this Powermac, and the only differences I can see are that I've switched to a different ISP (I switched from earthlink DSL to Comcast cable), and I now have 4 computers wired in to my 4 port switch router. After turning on my computer I also noticed that my router requires a reset and the internet doesn't work until I do that.

I've got a strange issue with my PowerMac dual 1.8GhZ and I can't figure out where it's coming from.Last Saturday I experienced a Kernell Panic while using Safari and the Dictionary (MacOS 10.5.1).Since then, whenever I try to start my computer, it shuts itself down while the grey screen with the Apple logo is on screen. However, this isn't always the case:I can use my computer 'normally' if I press the option key at start-up and manually choose my startup disk.
I can boot from a Panther or Tiger installation disk, but not Leopard.If I try the hardware test the computer shuts itself down in the middle of the test.TechTool works and didn't find any issues with my computer. Nor did Disk Utility.I tried to erase both my internal hard-drives and do a clean install of Tiger, but the problem is still there (I have to press option at startup).I tried to reset the PRAM and Cuda/PMA. Doesn't resolve the issue.When I tick 'Restart automatically after power failure' in Energy Saver my Mac will indeed restart, meaning it thinks there was a power failure.Any idea what it might be? And why it only happens in certain situations?Do you think it's a hardware or a software issue?

As soon as I unplug the power of my MacBook Pro, it shuts down, and all of my unsaved stuff is lost.
PS Is the battery user replaceable? I am using the Mid-2010 model.
I can't for the life of me find those dock indicator lights that are bright blue and shaped like power indicators, like the logo on the MBP power button.
I had them before and have been searching for an hour and cannot find them anywhere.
My MacBook Pro 13" Mid-2009 has recently started to shutdown unexpectedly when it starts running on battery power, I don't know if its the battery or the motherboard (I hope it isn't).Â
I tried resetting everything, reinstalled the whole OS, repaired permissions (don't know what for), but I keep getting this. It started about a month ago when I tried to boot up from the battery as power source:
The first try went all the way through the apple showing up with the spinning symbol underneath it, then POOF. Then everytime I tried to boot up again it didn't even show the Apple logo, just 5 or 6 seconds after the chime, POOF AGAIN.
So I connected it to the power adapter and everything went OK, I started working on it, everything was fine until I disconnected it. I kept working on battery and 2 minutes later the computer died again, it sounded like when you keep pressing the power button to force-shutdown, like it's protecting itself from something and it's very frustrating not being able to use your LAPTOP as one.
Oh, one more thing, the battery icon says "Service Battery" and it shows only 1 hour of battery (on 100% charge) the 2 minutes I can work on it before it shuts down.

I have a 13-inch Macbook, Late 2008 model, using iOS Mavericks. While on battery power, the laptop will randomly just turn completely off, despite still having plenty of battery power left. I know it's not a calibration issue where the battery is dead but appears to have charge left, since I'm able to turn the computer back on again and continue using it.Â

I have Western Digital My Book Pro II 2TB hard drive connected through FireWire 800 or 400 cable. The problem is that it shuts itself off unexpectedly all the time. Sometimes right after I turn it on, sometimes after 30 minutes. After turning it back everything seems to be fine, no loss of data. Anyone else experienced the same problem and can suggest how to fix it?

I've had my macbook for about 15 months. i noticed a while ago it had trouble turning off completely when running only on the battery. then a few weeks ago it shut itself off and wouldn't start up again. the power cord indicator was orange, but nothing worked. ordered a new battery, that didn't help. tried a different power cord - nada. i took it in to an apple repair shop and they said something about the internal power connector (i'm not a techy) and took 2 weeks to repair. i've had it back 3 weeks now and the same thing has happened. only this time there is no indicator light on any of the power adapters. and my partially charged batteries do not work on their own either.
any ideas? i don't want to keep fixing the same thing and every few weeks it keeps breaking again. i mean, what's the point in having the computer then, right??
My iBook G4 crashed on me one night, and the only way I could turn it on again was to unplug the power cord from my computer, turn it over, remove the battery, put the battery back in, plug the cord back into the computer, hold down the start button, and it would restart. Although, when it restarted, the fan would go on first, and then the computer would make the normal start sound. Some times the finder would be on the screen after I restarted it displaying a quick link icon of the hard drive. So after a few weeks, it did it again, then a few days, and then it got to the point where I had to keep my computer in the same position otherwise it might shut down.
Now, if the power cord is green everything is fine, but if I move my computer and bump the cord into the wrong place it turns from green to bright red, makes an evil buzzing sound, and in three seconds the computer shuts off and I have to restart by using the method above. If or when the power cord goes bright red I do have 3 seconds to pull out the cord before it shuts down. I then sleep the computer, put the cord back into the computer, and move the cord around until it is green again.
I took my computer to a mac genius, and when he looked at the crash report he said it was frequent, but not caused by the battery and couldn't tell me what was the exact problem. I bought a brand new power cord, but I still couldn't move the computer around to much or it would shut down.
1.) Has anyone ever heard of this happening? And if so, what causes it to be so touchy?
2.) What can I do to fix it myself?
3.) If I send it in, will they be able to fix it so that it is perfect again without having to spend more than the money assessed?
I would like to try to have it fixed. At this juncture, my only option is to send it in for $280 and hope they can fix the problem that no one seems to know what is the exact problem, or even where the problem stems from. I should add here that the battery is fully charged, and the report says it can hold about 1 hour of life, although it's more like 30 minutes, and then without warning to plug in or risk shutting down (like it used to give me) it will shut down.
I got my macbook during November of 2009 but two weeks ago it started shutting down by itself once I touch the magsafe of the macbook or remove the magsafe. All it needs is a simple touch and it shuts down. When it does shut down, the light indicator doesn't come on anymore. I have to keep removing the magsafe, and plugging it back in like 20 times until it starts charging again. So now I just let it fully charge every time I use it since any sudden movement will cause it to shut down. I will be making an appointment next week at the apple store because I had no time to go these past 2 weeks. I never dropped it and take good care of it. I am just wondering what might be the cause of this? I hope they do not take weeks to fix the mac since I have a lot of homework to do
