MacBook Pro :: It Won't Power On, How To Find Fault

Jun 29, 2012

I bought a faulty MacBook pro off eBay really cheap, it's immaculate condition externally but it won't power on. It came without a battery,charger or a HDD. The power adaptor came today and I put it in, without any battery or HDD would anything happen when you press power or not? Otherwise I'm assuming it's a possible logic board replacement?

MacBook Pro :: Fix Electric Current Fault

Jun 6, 2010

I was an owner of a white macbook for just over a year until the motherboard decided to give up the ghost... So I eventually bought myself a new 13" Macbook Pro. Everything was going just beautifully, until I realised when I was charging it, I had this weird electrical current going through all the aluminum.First of all the first two things that came to mind was. What's the computer and most importantly MY health going to be like if its exposed to all this! Anyway. I read a few threads, and they were talking about the "Grounding" problem. Luckily I got my old macbook charger out and plugged it in.. The problem went! So I was then thinking on where in the charger lied the problem? So I took the cable part from the Megasafe to the socket from my macbook, and then put it into my macbook pro Megasafe... and everything worked brilliantly! I'm no genius, however if you guys feel that tingly electrical/static current going through you're MBP, go and buy yourself a new cable. However as Apple is so popular, I'm sure if you try one of you're friends (As they will undoubtably have one) and see if it is that the problem. In anycase, I'm very happy with my Macbook Pro Apple make some awesome products. Bill Gates should just pack up and go fishing if you ask me. He can never compete with Me old mate Steve

MacBook :: Blank Boot - Potential Logic Board Fault?

Aug 18, 2010

After using a PC laptop for six months or so (and it really messing with my eyesight) I thought I'd try to revive my old macbook. Basically 70/80% of the time it won't turn on. There are these patterns of faulty behaviour which I hope you guys could diagnose:

1. I'll press the power button, I hear the disk noise, and the screen is black (i.e. not a backlight problem). The chime won't sound, I can just hear the fan and the hard drive whirring. The only way to get out of this is to power it off via the power button.

2. Sometimes after it's started up successfully and I move the Macbook (say, from a desk to my lap) the same thing will happen - black screen, with the rest of the stuff whirring, and if I try to shake it around nothing happens, I have to power off.

3. Occasionally when I power on, I just get the disk noise, a white screen, but no question mark, no apple logo, nothing.

4. Another time I tried to boot up with an external hard drive fitted and just got the chime over and over and over. Removing the drive solved this.

5. One time the screen just greyed out and a message in about 5 languages came up saying I needed to shut down my computer NOW.

This is not a hard drive fault - I saw that apple had extended the warranty on the hard drive because the question mark usually pops up for half a second at startup, and the nice guys at regent st London just whacked a new hard drive in, with a clean install of leopard (which was cool, I was previously on tiger at the time). I read something about resetting the PRAM (which I haven't tried), but I'm guessing it's the logicboard/motherboard. If this is the case, any idea how much it costs to fix? (My macbook is out of warranty). Figures in GBP appreciated but I can convert USD estimates. Is there any way I can try to blag a free motherboard and install from apple by exaggerating some symptoms?

MacBook :: Can't Find Purpose Of AC Power Cord

Jul 18, 2010

I had just received my first macbook a short time ago and I was wondering what the exact purpose of the AC power cord was.

Is it simply an extension cord to the charger? Or does it have a different purpose?

ITunes :: Freezing Up - Smart Playlist At Fault?

Jun 17, 2012

Recently I've started creating and using Smart Playlists.  And ever since I created a Smart Playlist - when I make any change to the metadata (artist, album title, anything at all - even just changing one letter) - iTunes freezes up for about 10 to 20 seconds as the wheel spins and iTunes processes the new information.  But in the meantime iTunes is rendered completely frozen up for me.  Same thing happens if I begin importing (whether from CD or just dragging) new music.  Is this sort of thing normal?  I assume it's the program processing the new information for the Smart Playlist, but for pete's sake, does it have to render the complete program useless?  Smart Playlists are a nice idea, but they have made iTunes a nightmare to deal with!

Mac Pro :: USB Or Peripherals - Screen Hub / Main Unit Intermittent Fault?

Apr 14, 2009

This is something I've been wondering for a long time. I seem to have a lot of screen-related issues with the Pros that I sit in front of in the main. Brightness controls going haywire displays not turning on, etc. There is also the odd attached USB device lockup, but I'd been putting this down to the devices themselves and the occasional, app-level instability of Leopard. More recently though, I've been seeing a pattern that's leading me to suspect the Pro's more than the peripherals. Is there a documented case of possible USB hub connection issues in (fully patched) 2008 Pros? The most frequent issue is monitors not behaving as expected when the system is booted until the monitors themselves are unplugged from power. There are also less frequent but present problems where iPods lock up, keyboards stop working, etc. I can't really abstract the problem down to an OS issue or a hardware issue, but the need for me to unplug the monitors seems to indicate that there is some sort of USB initialisation issue - as with the other minor problems I experience with other monitor-connected USB peripherals. Since I only use multimonitor environments as far as my Pros are concerned, all USB connections are usually made from the backs of the screens. So the big question is is this a screen USB hub fault, or a main-unit intermittent fault? All of the monitors I'm using have been to Applecare for one reason or another, although I'm not sure if they check everything in these repairs.

Can anyone else shed more light on this issue? It's pretty hard to replicate reliably and it's not been something I can go to Apple with any degree of certainty, yet the little minihoops I have with this problem (and oh so many other Apple issues, but that's by the by) irritate me immensely in comparison to my rock-solid, near-zero-such-issue, non-Apple environments which I also use daily.

IMac :: 24" Black Screen Flicker - Is It Lcd Fault

Jul 29, 2010

Recently i've started to experience my iMac screen flickering for approx 2 seconds, and then turning back on. I was wandering if this was a common problem with this model of iMac (purchased mid-09, 2.66ghz 4gb ram model). I had read of such a problem with the new 27", and in some cases even with the 21.5".

I have only recently begun to use the iMac for relatively graphically-intense tasks, and was wandering if perhaps it could be a dying graphics card (or perhaps it was always faulty, but the lack of intensity of any programs run never pulled it up originally?), or if maybe it was an issue with the LCD?

Intel Mac :: 27" - Color Calibration - Fault/Failure?

Feb 15, 2012

Earlier today I had the LED Panel replaced in my 27" iMac (Applecare Warranty) due to a screen discoloration that had appeared around the Optical Disk area of the screen. The replacement LED has resolved that issue. However, (and I don't know if this is due to the new LED installation) I now find that I cannot 'color calibrate' the new screen. On opening Display Preferences/Color, there are three display profiles listed;

• iMac
• iMac 27 Calibrated
• My 27 iMac Calibrated. 

On selecting any of the above and clicking the 'Open Profile' button - I'm given this message; Unable to determine file format. The file "/Library/ColorSync/Profiles/Displays/iMac-00000610-0000-9CB5-0000-000004272D40 .icc" does not appear to be compressed or encoded.It is advised that you obtain further information about the contents of this file from the sender or provider of the file.    On selecting the 'Calibrate' button - I'm given the message; Can not calibrate the display The factory profile for the display could not be found.

Applications :: ITunes Cannot Find Music Anymore (Mass Find Option)

Jan 30, 2009

Yesterday, I had to re-format my external hard drive so that it could be "recordable" within Pro Tools, which wasn't a major issue, I just had to move everything from my Lacie drive to another drive, do the format, and then throw it all back on. It took a little while but this also included moving my nearly 60gb itunes library. Now that it is on the newly formatted hard drive, itunes doesn't seem to be able to find the majority of the songs any more. I've tried changing the music folder and a few other things, and there is no way I'm going through and doing the "cant find music - click here to find it" palava. Is anyone aware of a way that you can "mass find" all of the music in any way other than starting the library again and adding all the music (I don't really want to lose all of my play counts and ratings if possible!)

PowerPC :: Powerbook G4 Won't Power Up - Battery Indicator Showed One Flickering Power Circle?

Mar 19, 2008

My girlfriend has a 12 inch Powerbook G4. She noticed that the battery life was starting to dwindle. Tonight, she tried using it. It wouldn't power up. The battery indicator showed one flickering power circle. The adaptor has the green circle on it, indicating the battery has a full charge. However, the computer won't charge up.I've read the 12 inchers don't have separate PMUs. Could that prevent the machine from starting? She was using it earlier this evening, as she e-mailed me pictures from our vacation.

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.

Hardware :: Repair 23" Cinema Display (no Power After Power Surge)

Apr 18, 2008

I had a bad power surge (USB hub that was plugged into the back of the display had the wrong power cord plugged in... very stupid mistake I know!!) take out my 23" Cinema Display. The display shows no sign of life (no power light, etc) and the brick has been tested and is OK. My local service place says that they will have to send the display back to Apple which means a minimum of $400 for repair so I'm wondering if anyone has had a similar issue that they resolved successfully? The service place suggested that Apple would replace the logic board but is there any way to test to see if this is the main issue? I have seen logic boards sold separately online but would be hesitant to buy it without know that this would fix this issue.

Power Mac G5 :: G5 Power Supply Beeping/Churping Corrected With Leopard

Nov 8, 2007

I made this a new topic because I think it is important enough to do so. Probably most of those that originally complained about this have moved on to the new MacPro but I am sure there are still enough G5 owners out there that still have concerns about this topic.

A clean install of Leopard eliminates the infamous power supply beeping

Its amazing, my G5 is like a new machine; no more of the annoying power supply beep; although, I learned to live with it after a while and didn't even notice it. However, the silence is now very noticeable.
