Power brick plugs...

Hey everyone,
I have an iBook g4, which I love taking on the go. When it's tied down at home, I use the plug cable, when It's with me mobile I prefer to use the plug tip that plugs right into the power brick, which brings me to my problem.
I lost the plug tip. Now here's my question:
I have a power adapter for an iPod charger that looks identical in every way, and fits perfectly as well. Can I use that with the power brick to charge my iBook on the go? I never use the iPod charger, so it's no loss to me.
Is this safe, or am I going to fry the charger? My guess is since it only carries AC into the brick, it would be universal, but I don't know...
Any ideas?

As John said, it will work. You can also use generic figure-8 power cables that come with devices such as radios or purchased individually from radio shack etc.

Hot-swapping power brick plugs?

I just got my C2D Macbook, my first portable. I'm planning to leave the grounded 3-prong cable plugged into the surge protector at home, and only use the 2-prong wall plug at work.
Not a problem at work; I have to unplug the whole brick assembly anyway. But when I got home and swapped the 2-prong for the 3-prong cable, there was an audible and visible spark. It wasn't connected to the Macbook at the time (IIRC).
Is it safe to do this? Or will I have to unplug the 3-prong from the surge protector every time I want to swap the 2-prong in?
Thanks!

I personally don't like arcing in any kind of electronics, even power supplies. I use a short extension cord for the surge protector. This way I just leave the two prongs always on the brick and just plug it in wherever I need. If I am at home it goes right into the extension cord and no arcing.

Apple ADC to DVI Adapter -- Power Brick gets HOT

Hello all,
I just purchased an Apple ADC to DVI adapter to connect my 23" Cinema Display to my new Mac Pro. It works perfectly, but I've noticed that the white, square power brick is generating quite a bit of heat. It feels sort of OK (within tolerance) at the edges but toward the middle it's noticeably hot. Not hot enough to burn my hands, or cook an egg, but definitely toasty warm. Is this normal? Or does it sound like I have a defective one?

If by "on" you mean the adapter is connected to your display and plugged in to an AC outlet, and you have an image on your display coming from your computer, then it's not dead.

Power brick/ charging problem 2011 MBA.

My wife's 2011 13" MBA has suddenly stopped recognizing the charging cable when attached to the air, and so not charging at all. No recognition LED at all orange or green, nothing. I've done all the ususal stuff, switched power plugs, took off the extension cable, put it back on, ect, ect...
I was about to go see Apple but realized I have a 27" Apple LED display for my Mac Mini. I attached the charging cable from that display and walla! It took and started charging immidiatly. So that tells me its NOT the Air itself thats the problem, its the charging cable somehow. Its either the power brick and that cable or both of them. I looked up my year long Applecare ( I didnt purchase the additional 2 years ) and saw that I have at least until Dec 8th to get it in there to have the cable replaced after they do their own testing....but we know what the problem is. I bought the Air from MacMall, not Apple so they are assuming that its Dec 8th but its later than that and I can find my reciept from Mac Mall and find out and bring it with me.
ANYWAY....is or HAS anyone had any problems like this at all? With any other Mac? I have the new retina and my magnetic power adapter is different so I can't test it that way but it did work via the display. I guess I'm asking if anyone has any experience with ths issue?
Thanks!

If I understand you right, you have already proven that it's the charger which is defect. So, go and have the charger replaced. Depending on what caused the defect you may get a new one under warranty.
If it's no hassle, take the MBA with you to test it on site with a new charger.
Other than that and FWIW, I'm sure you'll find other people who found their charger dead one day. Why, would that help?

Power brick covered under AppleCare?

I'm having some odd issues that seem to be the fault of my power brick (but who knows?). If I leave my PowerBook G4 1.67 Ghz machine plugged in for 10+ hours or so, the computer will stop recognizing that it has power. The light goes out from the ring where the cord plugs into my powerbook, and the battery slowly drains if the machine isn't asleep.
Unplugging and plugging back in the power cord doesn't work. The only thing that works is unplugging the power cord from my surge protector and plugging that back in. Or, removing the brick extension cord and reattaching it to the brick.
Has anyone had similar problems and/or know if the brick is covered under AppleCare?

the power unit is covered by the same warranty/applecare cover that applies to the device it came with
from your description imho it is more likely that the power unit is faulty than that a fault with the pb is causing it to shut down

T400 Power Brick needs annual replacement under heavy mobile use?

Just called to have a T400 Power brick sent to me, the machine is still under warranty so it was at no cost to me. I seem to be going at the steady rate of consuming 1 power brick per year, and I was wondering if this is normal for other heavily mobile users. I use my machine for school, and I bring the brick with me when I travel to campus, so the brick gets plugged, unplugged, and wrapped up and shoved into a bag about ten or more times per week.
The first one simply stopped working after about a year. The second also survived for about a year and it seems like there is a loose connection on the side of the brick that connects to the laptop.
Just wondering if anyone else has had similar issues? Can anyone recommend a way to treat the brick more gently so that I can make one last more than a year?

This doesn't sound normal. I toted my T400 adapter around high school and a half of first-year on it's original adapter. The adapter still works. (Maybe because I put the Intel Core 2 inside sticker on it? )
I think if your wall power has unstable current or voltage, it may wear out the adapter faster.

30" cinema dead: power brick, graphics card, or other problem?

so, everything was going fine, then I hear a power surge beep through my Ups, and my apple 30" display goes black. checked all connections, plugged in a spare monitor. checked and changed power connections, and all other advice from initial troubleshooting. computer seems ok, it shows both the apple cinema display and other monitor are active in the system preferences. but the power brick is cold, and no power is getting to the cinema display.
What are my next steps to see if my power brick has failed or some other problem has arrived?
Thanks in advance.

Determined that one of my internal harddrives p**ped out at the same time. This may indicate a power surge ran through the machine. Apple hardware test hasn't been able to complete testing, it locks up after a few minutes.
I know these monitors and in the under $500 range nowadays, but it has been such an awesome monitor, I would hate to see it die.
How to determine what is wrong with the monitor?

Late 2013 Retina Macbook Pro power brick extremely hot to the touch! This affected my computer (It was hot as well) - I could smell something burning! I am unsure the issue!

Hello,
I purchase the latest 2013 Retina Macbook Pro, which I pluged in my charger and walked away from my computer! When I arrived, my computer was in sleep mode and I noticed a faint burning smell and felt my computer and it was extremely HOT! I then felt the power brick and it was even hotter! 10 minutes after I awoke the computer (ESTIMATED), the computer actually cooled down... It's not hot to the touch but still warm! On the other hand, the power brick is still extremely HOT!
Please help! I started the charge at 3% and awoke it around 78% and now it's at 89%
Also, how long does it take to charge from 3% to 100%? It's been about 2 hours to reach 89%
Thanks,
Anthony
NOTE: Any support would be great! I could use the advice as this is personally my first MAC! I am thinking a software update to fix the computer from heating up when sleeping but I am unsure about the power brick!

I always thought that keeping it plugged in nearly 24/7 can damage the battery too?
No, not at all, the only damage from being plugged in all the time are IF:
A: its not turned off and in sleep mode ALL the time while plugged in
B: you dont unplug it ever couple weeks or so and drain the battery down to about 30 to 40%
*Also, if youre going to store your macbook away for a few weeks or more,... make sure it has at least a 50% or so charge.
*Cycle count / use/ lifespan is one thing that cant be countered.
Proper treatment is another thing. Just because LiPo batteries dont need conditioning in general,.. does NOT mean they dont have an ideal use / recharge environment. Anything can be abused even if it doesnt need conditioning.
Just use and enjoy your new macbook,
From Apple on batteries:
http://www.apple.com/batteries/notebooks.html
http://support.apple.com/kb/HT1446
but really all you would keep in mind is --"consider 15-20% is the same as 0% and recharge it"
Important useful info on your Lithium cells as compiled from battery experts:
Heat increases battery performance but shortens life by a factor of two for every 10°C increase above 25–30°C (18°F above 77–86°F). This is yet another important reason for the cooling of any notebook, not just keeping the processor and GPU cool. Mavericks lower power tasking (app nap) and combined with the cool running Haswell processor both greatly protect battery life on your Macbook now more than ever before.
Good news: *Mavericks not only increases a single charge cycle for longer battery use off a full charge,… but also prolongs the overall long term life of the LiPo battery in a Macbook by reducing the load conditions the battery experiences from heavy peak-use.
Counting cycles is not conclusive because a discharge may vary in depth and there are no clearly defined standards of what constitutes a charge cycle on a Lithium Ion battery empirically. Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count.
The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine.
Frequent HIGH depth of discharge rates (draining the battery very low) on a Lithium battery will hasten the lowering of maximum battery capacity.
Although better performing when warm, lithium polymer batteries live longer when kept cool.
Lithium cells prefer draining conditions at a steady pace rather than fast pulsed or quick discharges, …this fact is idealized now with the Haswell and Mavericks app-nap low power tasking for battery use.

Can I keep the power cord plugged in when battery reaches 100%l?

Hello,
I'm assuming the battery stops recharging when it reaches 100%, right? In other words I can keep the power chord plugged in without any risk of "overcharging". Correct?
Thanks.

Helpful, thanks. FYI, 2 Apple agents at Mac support have advised otherwise (said I have to remove the cord).
How bizarre....I have a 2.5 year old MacBook that gets great battery life (~4hrs) and begs to differ. Anyway, Thanks for the Star!

HP dv6500z Notebook: Power brick gets hot, HD area gets warm.

Hi:
I have an HP dv6500z notebook.
Is it normal for the power brick (suppy) to get hot ?
By hot, I mean that it is warmer than "warm".
You wouldn't want to keep you hand/fingers on it for a long time.
Similary for the Hard-Drive area and other area on the front of the notebook:
i.e., the areas to the left and right of the trackpad.
These two areas were warmer when I had the notebook sitting on top
of one of these Targus "cooler " stands that you place the notbook on:
it has two fans built into it to pull heat away from the notebook.
Thank you

No it is probably the biggest online marketplace for car parts and computer parts and other stuff. Think of it as a huge swapmeet with some retail stores mixed in...virtual of course.

Power adapter plugged or unplugged when using an external display?

My iPhone 4S screen is suddenly not reacting. The screen has turned a light blue color but nothing is happening. I have tried several things such as holding the power button, plugging it into the wall, and plugging it into my computer. What should I do?

Sounds like the device was dropped at some point and damaged as a result.
Take it to Apple for evaluation and a replacement.

MacBook using a Pro power brick?

Is it okay to charge my MacBook with a MacBook Pro power brick/adapter?

Steven Kent1 wrote:
So the 65W Pro power brick will not damage my MacBook battery?
The MacBook Pro supply is 85 Watts not 65 and it will work fine on the MacBook. I use one as a spare for my MacBook. It runs much cooler when charging than the original power brick.

HT201412 I can't get any power while plugged into computer when trying to reset my iphone

I can get power when plugged into electrical outlet but as soon as I take it out and try it in the computer to be plugged onto Iturnes it shuts off. I'm trying to reset my phone.

ohhh
thats not right
but it doesn't matter does it
just charge it up before you plug it into your computer
or if it really bugs you take it into apple they'll sort it out for you

HT4124 can I keep the magsafe power adapter plugged in to computer all the time?

Can I keep the magsafe power adapter plugged in to my computer from the power source at all times?

it is ok to keep it in all the time, BUT at least once a month let it run the battery down to 10-15% then do a full recharge.
