Opening up the Power Adapter

Does anybody know if you can prise open the power adapter so I can adjust the cable?
My cable is starting to fray near the adapter end of unit (from where you start winding the cable around the two prongs when you are transporting the unit) and I don't want to have to pay £55 for a new one. When a plug becomes faulty I simply open the plug and do what I need to to the wires and then we're back in business.
There is so much stress on this end of the wire that will happen again and again. A poor piece of design for such a great company!

Well after trying to hack into the adapter I decided to purchase a new one! It's worth looking around though as Apple Store were quoting £55 for a new one and I managed to find an official Apple one, brand new, on eBay for £30

Doesn't recognize the power adapter. Have replaced battery and PRAM.

Howdy,
I'm having a devil of a time with my Powerbook. It won't recognize a power adapter.
It won't charge my battery.
Won't run when plugged into the power adapter.
The only way it works is for me to charge my battery in my girlfriend's Powerbook and then sprint through any work I try to get done.
I've replaced the PRAM with twice. (one i bought and the other I took from my girlfriend's which I 100% know to work) It didn't make a difference.

Welcome to the Apple discussions.
There's only 4 components in the charging circuit: power adapter, DC-in card, battery, and logic board. Do you know for a fact that your power adapter is working? If yes, then not running on the power adapter says either the DC-in card is bad (the card that has the jacks on the left side of the computer) or it's a logic board issue. Is the female jack where you plug the power adapter in visibly damaged, loose, or the case around the socket damaged? If the socket is wiggly loose, likely a new DC-in card is in order. Does the power adapter light up at all when you plug it in?
We had a similar, but not exact, situation recently on one of our Powerbooks, and ended up taking it to the Apple store, where they sent it to the Apple depot for repair. They replaced the logic board and put a new battery in. The Depot service returns the machine with anything needing repair, repaired. If everything is in good physical order, ie the case isn't damaged, it costs around $325, which is less than getting a new logic board put in at the store. If the case is damaged, a trip to the Apple depot costs more. A new DC-in card card + installation by Apple runs around $130, give or take. Used DC-in cards run around $75-$95 if you want to install it yourself.

ZR65MC camcorder does not turn on with battery in position unless the power adapter is plugged in

Bought a ZR65MC camcorder in 2003. Enjoyed it so much, but a couple of yrs. ago, the tape compartment stopped opening. I just purchased another ZR65MC (used) on ebay in hopes that I could at least get the videos off & onto DVDs. Also, we are planning trip to Yellowstone soon, so camera/camcorder will be nice. Problem: The used one does not turn on with a fully charged battery unless the power adapter is plugged in. I assume battery is good because it turns on my older camera. I do need backup batteries in both, but have not done this yet. Please tell me I have not purchased a bad camera, maybe just doing something wrong? Would have never purchased a used camera online, but did this time. I have ordered a new battery BP-522 with wall charger. It should arrive next week. Any suggestions?

Hi Sharon72064,
If the new battery won't power the camcorder without the Compact Power Adapter, unfortunately, it's likely that an internal component has malfunctioned.

Sleep and the Power Adapter...

I have been having iBook sleep problems and here is an example. working on ibook with power adapter in. i close the lid and it goes to sleep but wakes up and goes back to sleep then finally its asleep. ok i click on my mouse and it wakes up. another would be i manually go and click on the sleep option and while the lid is open it sleeps wakes sleeps wakes...finally sleeps. i close the lid click the mouse it wakes up... so i decided to reset the PMU and everything and did the same test and the same things happend. then for some reason i said let me try this with the power adapter unplugged. so i tried it and now the sleep function is perfect. i put it to sleep without the adapter and i press on the mouse and it stays asleep untilll i open it...weird but does anyone know what i could do to fix this when its plugged in? anyone else have this problem? thank you.
iBook G4 14 inch. & Imac G4 15 Inch Mac OS X (10.4.1)

Hello Steven,
I think the reason this is happening is just because of the mouse that is connected to the ibook. I have an external mouse that I connect to mine. When the ibook is connected to the power adapter, it will wake up if the mouse is clicked, because it is getting a signal, and therefore wakes up, then goes back to sleep (when closed) because of the switch inside the computer telling it to sleep. This also happens if you connect something to a USB port. I don't know exactly why this doesn't happen when it is not connected to the power adapter (Maybe to conserve battery power?), all I know is that it just doesn't happen.

Stop the sleep blinking light in lenovo g-470, whining sound from the power adapter , HEEEEEELP !!!

Hi, hope anyone can help me.
I own a lenovo b560 and a g470, the sleep light will blink when I go to sleeping mode, anyway the problem is not the light, the problem is the whining sound it produces the power adapter when the light start blinking, in both machines I hear that whining noise, but in the g470 is much louder, I don´t know if this is because I have a faulty adapter or something, the strange thing is that both adapters make the noise when I sleep the laptop, when I turn off or hibernate the whining sound disappear.
Also, I notice that the whining sound alternate in 2 types of sounds, one is high in pitch and the other lower, the high pitch is when the blinking light turn on when go to sleep and the lower pitch of the sound is when the light go off, and that is repeating until I resume the laptop, it´s very annoying, especially when I´m in a quiet room.
So my theory is that maybe somehow I can turn off the blinking light when the laptop goes to sleep and then maybe the whining sound will go away, but I don´t know, it´s only an a idea.
Any help will be appreciated.
Thanks !
Solved!
Go to Solution.

I can really understand your pain with this issue.
Kindly update the BIOS and display driver from the lenovo website then check if the issue persist.
The issue should be resolved after this.

Not able to install Logic on mac with OSX. 10.8.2. Error message: Logic Studio.mpkg cannot be opened as the power pc programs are no longer supported. I have logic studio 8 software purchased in 2007 and upgraded with logic studio 9 (purchased in 2009)

After an earlier attempt to move Logic from my other mac (OSX 10.6.8) with the migration assistant to my new mac with OSX 10.8.2. I've re-started the whole start up process by erasing the hard drive from the new machine and build it up from scratch. After a new "out of the box" start, I decided to install LOGIC from my disks : starting with my 2007 package Logic Studio 8 and upgrading with my Logic 9 package from 2009. When trying to start to install 2008 I got the error message : Logic Studio.mpkg cannot be opened as the power pc programs are no longer supported.
What does this mean? HOw do I get this working under 10.8.2 as it works flawlessly under OSX 10.6.8. For sure I didn't buy a new machine to have OSX 10.8.2 but I suspect this is the roadblock to installing my logic package.
Help!

Mark,
Sorry...
I completely lost the thread (I actually got confused between you and another poster on a another forum that was asking the same basic question) and somehow ended up thinking you were trying to install on a PPC Mac
My apologies and please ingnore those parts of my last post relating to the PPC Macs...
You have an Intel Mac and therefore Logic Studio 2 Boxed Upgrade set should install/run on your Mac without issue. As I said earlier.. you do not need to try and install from the original Logic Studio 1 /Logic 8 Boxed set...(It won't work anyhow because you have an Intel Mac and that version had a PPC installer) but just install from the Logic Studio 2 / Logic Pro 9 Upgrade Boxed setof DVDs instead...
Have you tried the "Make Disk Image" solution I gave earlier? That normnally works under such circumstances as what you are describing can happen when your DVD drive cannot read the DVDs correctly... I have had this situation myself where one drive read them okay and another failed to do so for whatever reason. Making and then installing from Disk images of those exact same disks resolved the issue for me...
You can try to reinstall directly from the DVDs of course though under some circumstances it may not allow you to reinstall Logic Pro itself if that part of the original installation attempt was successful... in which case you can also try this... (It's probably the easiest method if Logic 9 was already installed and present in your Apps Folder)
If the Logic Pro App is in your applications folder..
Run Software Updates to update Logic Pro to a version that will run under 10.8.2 (The initially installed version of Logic will not)
Run Logic
Go to the menu bar in Logic and select Logic Pro/Install Additional Content and select all content in there..
This content is basically exactly the same as what is stored on the remaining DVDs of the boxed set so you might not need to use the rest of the DVDs to install from but download it all instead from Apple Servers...

Laptop won't turn on - the power adapter light flashes three times? G62 b29SA

I've been replacing the fan in my friend's laptop. I had a problem with the trackpad not working after I put it back together and that problem is not yet resolved but I have another problem preventing me from getting further. Now when I press the on button, the power adapter light (next to the socket for the external power) flashes three times and that's all. It flashes again three times every time I press the power button. It does this even with an external power source plugged in (I'm pretty sure that it's supposed to just stay on constantly when the charger is plugged in but the power source I have is a universal one set to 19 V - it has powered up with this plugged in before but I don't know whether it was taking charge from it). Any advice?
This question was solved.

I got the charger from my friend and now it boots up just fine. There seem to be many meanings to the three flashes based on my Internet searches but in this case it appears that it's some way of indicating a low battery.

Why does my macbook only turn on when the power adapter is plugged in?

The battery life says its at 73% and climbing but whenever I unplug my power adapter the mac automatically shuts down and if I try to turn on the macbook without my power adapter plugged in, it wont turn on. How do I make it go back to where I can turn the mac on without it being plugged in? Thank you for your help!

I would try two things the first being resetting the System Management Controller:
1) If the computer is on, turn it off.
2) Disconnect the AC Adapter and remove the computer's battery.
3) Press and hold down the power button for 5 seconds and then release the button.
4) Reconnect the battery and AC Adapter.
5) Press the Power button to restart the computer.
If that doesn't work I would recalibrate the battery.
To calibrate the battery:
1) Plug in the MagSafe power adapter and fully charge the MacBook or MacBook Pro battery until the light on the MagSafe connector changes to green and the Battery icon in the menu bar indicates that the battery is fully charged.
2) Allow the battery to rest in the fully charged state for two hours or longer. You may use your computer during this time as long as the power adapter is plugged in.
3) Disconnect the power adapter with the computer on and start using it with battery power. When the battery's charge gets low, you’ll see the low battery warning dialog on the screen.
4) Continue to keep your computer turned on until it goes to sleep. Save your work and close all applications when the battery's charge gets low and before the computer goes to sleep.
5) Turn off the computer or allow it to sleep for five hours or longer.
6) Reconnect the power adapter and leave it connected until the battery is fully charged. You may use your computer during this time.

The power adapter gets very hot. Any suggestions?

The power adapter part that plugs into the computer gets very hot. I have replaced the battery and replaced the power adapter. It also has a hard time connecting and recharging the battery. Is it possible to change out the plug in part in the computer and is it expensive? Does it sound like this is what is needed to fix it? Its about 3 years old. Any suggestions would be appreciated. Thanks.

Hot is normal for the charger but very hot is not. If it were mine It could be that your MBP is drawing too much current. I would take it to the Apple Store and have it checked out.

Noise on audio output when using the power adapter

I'm a musician and use my mid-2007 MBP 15" in my live rig. When I use the power adapter, I hear a buzz, sometimes accompanied by a slightly louder buzz that cycles on & off about 1x/second. There are a few weird things going on here:
1. The buzz does not happen all the time. That leads me to think it may be noise in the AC line that the adapter is plugged into.
2. The noise is heard when I use both the built-in audio output AND an external USB audio interface.
In any case, when I disconnect the power adapter and run my MBP on battery, the noise goes away completely. I can probably do this on most gigs, but I'm a little nervous since I run a FW drive, an external USB audio interface, and my midi keyboard (powered by USB) so I am putting a little heavier than usual load on the MBP's battery.
As I said, this may be a noisy AC line. Another guess is that it's the PMU inducing noise into the audio circuitry. I'm hoping a simple AC line filter can help me but I thought I would ask here first in case anyone else has dealt with this. TIA for any help!

I had a similar problem and fixed it with a $5 universal travel adapter. Yours might be different but here's my situation. Try it for little cost and see if it works.
I'm also a muso with an iMac running external KRK speakers via USB Mbox2. Previously I had a Macbook Pro and the same audio problem. I've been putting up with a very low volume, high pitch noise until now. I simply plugged the Mac power cord into a universal travel adapter which then goes into the wall. For Aussie users there is an adapter on ebay that will allow a 3 pin Aussie plug to go into female side and has a two pin Aussie male on the other. For US users you can probably get the same although there is a 59c product that will do the trick called a ground lift adapter. Applecare actually agreed this was the best fix and confirmed there would be no problems with power supply or Mac performance. What a gem ! God knows I've looked into all kinds of alternatives that could have cost hundreds instead of $5.

Where can I find a replacement for the power adapter tip?

I need to replace the small adapter that allows the power adapter to be inserted into a socket. Does apple sell this part separately?
The adapter itself works fine. But the tip that gets inserted into the adapter, and then the wall, has started to make sparks. I'm afraid it's going to catch fire, or cause a fire. When plugged into the wall, I hear sparks and I see smoke coming out. If I adjust it's position by slightly withdrawing it from the wall socket, so that there is minimal contact, the sparks stop. But I am a little worried now that I can't leave my MacBook Pro retina plugged in without risk of fire. This started about a month ago after two years of use without any issues.
To be clear, I'm not talking about the adapter itself, but the tip that gets inserted into the adapter, and in turn allows the adapter to be inserted into a socket.
It seems wrong to shell out $80 for a whole new adapter when all I need to replace is the wall adapter.

I dont know what is wrong with my computer,if is it because there is something wrong with my MacBook Pro or if its the actual power adapter or the string that attatches the power adapter and the computer. HELP PLEASE!!!

Have you tried to do an SMC/PRAM reset?

Question about the Power adapter

I just got my Macbook and I love it but I'm a bit confused as to the function of the power adapter. I plugged it in and it started to charge my battery. Is this supposed to happen? I thought the function of the adapter was to provide continuous power from an outlet supply. Maybe I'm under the impression that the second cord I received with my macbook is a power supply cord. Is it?

Also You can run the computer without your battery in but I believe it's not good for the computer.
This link explains the point you were making. MacBook reduces processor speed when battery is removed while operating from an A/C adaptor

Just purchased an 11" Mac Book Air, and I'm using it as a desktop. Is it ok to lea the power adapter connected all the time?

I'm using my macbook air as a desktop unit, with an auxiliary flat panel display, as well as an external storage drive and a CD/dvd drive. Is it safe to leave the power adapter connected to the computer all the time? Will the battery life get affected or shortened by being fully charged all the time?

Apple recommends that for best battery life, you allow the battery to discharge occasionally.
Here's a good link:

Overheating at the power adapter location shuts down computer

On occation Powerbook gets hot near the power adapter input. The unit shuts down with what sounds like the fan running, I must hold down the power button until it restarts. The unit is on a flat hard surface and the battery and charger function properly. I ran the hardware test, off the CD, which indicted all OK.
Any ideas of what the problem may be?

The best thing that you can do is purchase an enclosure for your internal drive (see -> http://eshop.macsales.com/search/2.5%22+usb+enclosures), use a Phillips #00 screwdriver and a Torx T6 screwdriver (also available in a kit from OWC/macsales -> http://eshop.macsales.com/item/NewerTech/TOOLKIT14/) and get the hard drive out and into the enclosure (it's quite simple to do and there are videos at OWC that will help -> http://eshop.macsales.com/installvideos/).
Once the drive is in the enclosure you can plug it into any Mac and retrieve your data. Probably the best thing to do would be purchasing an external drive and copying (or cloning, see -> http://www.bombich.com/) the data from your internal (now in the enclosure) to the external drive.
Then reverse the process, putting your internal drive back in place, and take your machine to your local Apple Store or an AASP. I know that it sounds rather convoluted, but you'll be able to use the external drive afterwards to make backups (see -> Most commonly used backup methods).
Make sense? Or am I just being confusing?
