Power Mac :: G5 Stuck At Light Blue Screen - Will Not Even Boot In Safe Mode
Mar 22, 2012I have a 2.0 GHz early 2005 Power Mac G5 (7,3) that won't get past the light blue screen at start-up. I've tried everything - reset the PRAM, Apple Hardware Check (on overnight loops, everything came back OK), fsck (all OK), repaired my HD and permissions on it, and then erased the drive using Target Disk Mode and another Mac, and attempted to reinstall OSX from the install disk that came with it (with OSX Tiger). I've tried switching out the RAM with no luck.
The only thing I haven't tried is a new video card (the installed one is an ATI Radeon 9600). Here's what it does: powers on with the usual chime, then moves on to the white Apple screen, the wheel spins, then it moves on to a darker blue screen, then it finally moves on to a lighter blue screen with an arrow, and it just stays there. It will boot into safe mode (pressing shift), but I can't even upgrade to Leopard in safe mode, much less figure out what's wrong.
MacBook Pro :: Power Light Is Only Red?
Dec 8, 2010My Macbook Pro randomly shut off (I don't think it was low on battery, but I can't be 100% sure.) Now when I plug in the charger, the light on the charger is green for about 6 seconds, then goes to red and stays red. I cannot turn on the computer, and there is no sign that it is even charging.

Sep 10, 2009My Macbook, I have just become aware that the light for power on isn't on, nor does it pulsate on standby. Everything else seems to be working normally, so I can live with this. But could this be a symptom of precursor of a more serious problem elsewhere?

MacBook :: Cannot Power On - Magsafe Light Remains Green
Sep 28, 2009I've been asked to take a look at a friends white macbook that won't power on. I've tried resetting the smc etc., with no joy. The battery charge indicator shows 1 fully lit green light and the magsafe connector also is green. Pressing the power button doesn't do anything, no lights, beeps etc. I've tried another power adapter and the magsafe light remains green when connected but the battery still shows 1 green led. Considering the macbook thinks its charged but the battery isn't, is this a dead logic board? Or something else? This macbook is well out of warranty.

Nov 3, 2009I recently spilled close to a tablespoon of milk onto the keyboard. Most of this landed on the keys themselves. I thought nothing of this and continued working for 4 hours. I left for 6 hours and came home to a non working Powerbook G4. The green powerlight does come on. I let sit for one day. Still nothing.

Jan 23, 2010I went upstairs last night to find my Macbook Pro's charger had no light lit up on it. I tried everything including changing wall sockets, resetting the SMC, with and without the battery - nothing! I then noticed I could feel the electrical current on my Macbook Pro and then it started, a loud ticking coming from the brick. It's dead. It's just under 18 months old. Apple has said that I have no Applecare, no tech support and no warranty so buy a new one. I thought electronics HAD to have a 2-year warranty on them in Europe? Can I take that to apple? It's �60 for a new one and things like this shouldn't fail after just 17 months.
It's the old 85W type. The guy at Apple told me they only do the "new" 60W types. Can I use these with a June '08 Macbook Pro? I've had no end of problems with my MBP. I may call an end to Apple - I'm not happy paying over the odds for this Macbook less than 18 months ago for it to have had so many problems already.
MacBook :: No Power - Green Light On Connection Flickered
Apr 28, 2012My Macbook has no power at all. None from the cord, none from the battery which was fully charged. I noticed only a couple of days ago the little green light on the connection flickered a couple of times. I took the extension off the lead and used the plug on the power box. I also took the battery out and put it back in.

OS X :: MacBook Battery Not Charge / Power Light Stays Green
Sep 25, 2009I have a 2008 Macbook and when the power is plugged in, the light is green, however my battery will not charge, and it even says at the top "battery is not charging" If I remove the power cord from the computer it will still run off the remaining % of the battery, but If I reconnect the cord it lights up green and I never see the amber charging color. I traded out my battery as well as a different cord and still the same results. My battery will charge up on a friends macbook, but not on my own. I want to take it to the apple store but I'm at school and there is no store near me.

Feb 5, 2012Today I turned on my G5 to recover some files off an old iMac hard drive (can't very well read HFS+ using Windows), and my G5 refused to boot. Your press the power button, the power light flashes normally when you press on the button, but it powers on but the power light never comes on and there isn't a "bong" sound. The fans come on normally, but after a while the fans start picking up speed until they are at full speed.
I tried swapping ram, no change. Pulling ram, no flashing lights, pulling air deflector shield, full speed fans and red light (tells me something is working at least), swapping the video card, pulling the video card and still nothing. The 17" Studio Display power button works to turn on the system, but it has no light either saying the computer is on.
Based on the full speed fans after a while, I'm willing to say I have a failed processor, but that is just a wild guess as I don't normally work with Macs. The system is a Dual 2 GHz Power Mac G5 with 2 gigs ram, 80 GB hard drive, Plextor PX-712A DVD burner (I got this with a DVD-ROM), stock Radeon 9600 Pro and an Airport Extreme card. It runs Mac OS 10.5.8 and has worked great up until today.

MacBook Air :: Unable To Boot System / Magsafe Charge Light Is Green
Aug 31, 2008Sooooo I just got my brand shiny new CTO 4GB 13.3 MBA this morning at about 9:45 am yesterday in Illinois. I was sposed to go to bed because I am working nights at the moment but i stayed up for hours setting it up and playing with it (my first MAC) and so I finally get home after working a 12 hour night shift and open up my new MBA expecting instant on and....nothing. The damn thing will not turn on and I tried all the tricks of the trade (suggested by apple support page) and nothing. It was fully charged when I left it in the morning. Also, my magsafe charge light is green which means it is still fully charged right??? Man what a super disappointment. My first MAC and it freaking dies immediately. My Win 7 desktop at least started...good ole faithful (granted it took about 55 seconds...pff)
I'm so sad!
Mac Pro :: Power Light On But System Will Not Start Up
Oct 16, 2008I have a G5 Dual 2.5 and the power light on the front (white) is lit but nothing happens when I press the power button. I was trying to reset the PRAM manually by pulling the battery and inplugging the unit because my startup shortcut keys were not working. I had seen it recommended to reset it by pulling the battery and reinstalling in other threads. I put the battery back after about 15 sec and plugged in back in. Now it wont start up.

PowerPC :: Light Goes Out And Ibook Switches To Battery Power
Apr 2, 2007I 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 :: No Power On Powerbook - Recharge The Light Goes Green To Red Then Off. ?

Now when I plug it up to recharge the light goes green to red then off. I found a so called reset button on the apple site and lifted the keyboard and it is not in site.

Jan 16, 2009I recently received a Power Mac G5 from work. They told me I could have it, but reformatting the hard drive and reinstalling the OS was on me. So, I took it home, and plugged it in to turn it on, and the white light on the front blinks 3 times and then stays steady... and then blinks 3 times again... and so on and so on.
The RAM that came with it was bad, so I put in 2, 1 GB PC3200 sticks in it. Isn't it a RAM problem?
Software :: Won't Work To Wake Computer / Power Light Is On
Jul 24, 2009I've just recently purchased my Mac Pro and have tried multiple times to leave it on, with the monitor set to sleep (using hot corner) and the computer set not to sleep. The purpose is to be able to access my music library while on the go. For some reason, when I come back to the computer it won't wake, the power light is on so I'm assuming it froze or had a kernal panic.
I'm running Simplify Media and a Hawking USB wifi adapter to access my music on the go, no other 3rd party peripherals.
