Any converter from PC power adapter to macsafe2

I have a 2013 MBP 15. I want to get an extra power adapter, but the authentic Apple one is too expensive. I have a bunch of old PC adapters lying around. Is there a converter tip that I can buy to use my PC power adapter on the MBP?
Thanks!

I actually have a "universal" PC power adaptor that has many different plug styles (holes with different diameters), so if such as PC->MacSafe2 converter exists, I should be able to use it.

When charging and using, ipad 2 is 100% battery, does ipad use the power from the power adapter or from the battery?

I have a quention, when i am charging and using my ipad 2 at the same time, if the battery of ipad is fully 100%, does ipad use the power to work from the power adapter only or from the battery only or both? Thanks!

YOu don't have to have your receipt. Apple should have a record of how long you've had the device. If you bought it in april 2012, then your 1 year warranty against manufacturer's defects is almost up. You should find your local apple store, make an appointment and take it in.

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 !

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.

Wire that goes from 90W Power Adapter a1097 to apple cinema hd display

We lost the wire that goes from the 90W Power Adapter a1097 to the Apple Cinema HD Display. Where could I purchase another one and what is the name of this wire?

The wire that comes from the power supply is tethered, meaning non-detachable, so I don't see how it can be lost. Or maybe I am misunderstanding. Is it the AC cord that is missing, e.g. the one that goes into the wall? That should be a normal IEC 320 C13, which is commonly available. You don't need the Apple one.

Setup deskjet 3050A having trouble with the cord coming from the power adapter.

My deskjet 3050A power adapter has a black and white cord coming from it and ends with a a small black rubber and metal end. I can't figure out where this goes. My printer will not turn on anymore. It was working before I went in the hospital at the beginning of the month and I can't remember where this cord went to.

Hi,
Looks like your printer has broken during your absence, should be nothing hanging out with that description. I can't physically see it therefore I can't say anything because this can be live and death. You need an electrical or throw the printer away and get a new one.
Regards.

Verizon Westel 327W abroad - Buzzing sound from the Power Adapter ?

So I moved to Caribbean Islands for schooling and the DSL Modem from local company here was plain 1 port one. The voltage here is 220V, so I have put a transformer and then plugged my Westel 327W into 110V and it works great.
However, I am noticing a buzzing sound from within the power adapter. The adapter is running somewhat hot since I plugged it in a few days ago. Should I be concerned about this buzzing sound or is it just that its sitting on my desktop and I am noticing it now ? Its loud enough to be heard in a completely quite small room....
Thanks

Hi D_U, sorry to hear of your issue, sounds electrical and thereby out of my scope of support.

Not sure if problem is from battery/ power adapter

This morning I tried turning on my laptop, but nothing happened!!
I tried charging it, but the light is green (meaning it is fully charged). The battery indicator light only shows 1 light out of 5. Does this mean that the battery is dead???
Thanks!!!

The PMU reset is what was done for the Power PC Macs. The SMC reset which you linked to in your post is the correct one to do. They are the same type reset just different names for different Macs. It will not erase any data off your drive.

Power Adapter flashes orange light and won't power on.

I woke up this morning to find that my power adapter's light is off and it is still plugged into the surge protector.
1. When I push the button on the bottom, I get all 4 lights saying that it is charged.
2. When I plug the laptop with another adapter, I get a constant flashing orange light from the power adapter. Mine will flash orange several times and then go black. It's like it's trying to communicate something to me but I don't understand its language!!
3. I have tried resetting the computer, that didn't work.
4. I have tried powering up without the battery in the machine, that didn't work.
Any ideas out there?? I'm thinking that I need a new logic board but I also haven't backed up my info. Any assistance on either of these issues?

I found out that someone had spilt chicken soup on my laptop and it pretty much destroyed the logic board, optical drive, processor and other technical stuff.
*heavy sigh*

Disfunctional Power Adapter

I just came back from approximately 2 hours away from my power adapter this evening to find the amber light was still on (not connected to anything). The adapter was plugged into my power bar, so I unplugged it and the amber light flickered out after a few seconds. I then plugged the adapter back in and connected it to my computer. The indicator light turned on green although I only had about an hour and a half battery life left, and the charge indicator at the top of my screen said (Not Charging). I unplugged everything again, and now the green light turns on on one side of the adapter without being connected to the computer, and does not charge my computer.
I have had my Macbook for a year and four months without any problems pertaining to the battery or power adapter.
Also, I tried to register for a technical support phone call, but my serial number is not recognized as a valid serial number.
Help!

I'd advise you to just buy a replacement power adapter from any source. Amazon has some used ones, for around US$ 45:
http://www.amazon.com/Apple-MagSafe-Adapter-MacBook-MA538LL/dp/B000FQ245I/
On eBay, you can also find these:

Sites operating from Hong Kong (such as DealExtreme) have cheaper non-brand replacements, but can take 2-3 weeks:

Good luck.

Defective power adapter??

My iBook gave me quite the scare last night. (I'm using my Compaq Presario (w/ Vista, God help me!) to post this.)
My iBook had about 20 percent left on the battery, so I put it to sleep and plugged it in to charge it. About an hour or so later, I checked and the battery had drained to 18 percent. The plug light was amber, but it obviously wasn't charging. And here's what was flakey: There was a soft buzzing sound from the power adapter. When I shut down the iBook, the buzzing stopped and the light stayed amber. But I checked another hour later and the battery continued to slowly drain.
So, I checked these discussion boards, reset the PMU, took out the battery and put it back in, checked the power at about this mac (it was not charging and the battery had -- I can't remember exactly -- zero capacity), tried the power adapter with the 2-prong thing (without the three-prong extention), and the battery continued to drain. It finally got to the point where the iBook would go to sleep in less than a minute. I could barely power up or shut down. The iBook did nothing when I tried only the power adapter with the battery removed.
So I'm thinking do I need to replace the adapter, the logic board, the DC in board, the battery?? Then I again unplugged the power plug and checked the pin for damage. There isn't any. I plugged it in again and booted, and now IT'S CHARGING. And the About this Mac > power shows a healthy, charging battery. I shut down, and it's charging now, no buzzing noise, and I'm not touching it until the light is green.
Can somebody tell me what happened? Do I need a new power adapter? I bought this iBook new from Apple in September 2005. It has the orignial battery. I've never had any real problems with my iBook. What's going on?

Just an update, but I'm hoping that this problem is solved.
The new battery I ordered from OWC arrived today. I replaced the original battery and NO PROBLEM. I didn't have to wiggle the plug or anything. Everything is working as it should. The battery has charged 100 percent and I'm keeping the plug in for 12-plus hours, as instructed to calibrate it.
I'll know for sure if that was the problem after I drain the new battery to empty and see if it recharges as it should. But for now it looks like the 29 month old original battery was the problem. That kind of ticks me off because it still had 56 percent of its original capacity. It seems like I should have gotten another year of use out of it. When I removed it (and it was fully charged), it had 484 load cycles.
The battery from OWC ($99) was a lot cheaper than Apple's price ($129). Also, they were not overly helpful at the closest Apple store (23 miles away). I would have to bring the iBook in so they could inspect it. They would have to order the part (if it was the DC-in board) and I would have to make a second trip to the store. The part wasn't in, but even if it was, they wouldn't hold it for me, and they wouldn't order it for me until they inspected the iBook, and they wouldn't just sell me the part. I had to have it installed by them for $85. The DC-in board is $12. The cheapest new one I could find on line was $29.95 (and $9 shipping).
So ... I'm hoping the new battery fixed everything. All seems to be well.

Power adapter + booting

I have recently found that my iBook will not start-up unless the power adapter has been unplugged from the iBook for a few minutes.
I have been powering the iBook from the power adapter (and not the battery) for months.
After the adapter is unplugged from the iBook for a few minutes, and then plugged in again, pressing the power button works and it boots up. After shutting down, I have to do the same thing again every time I wish to turn my iBook on.
Another note - as soon as the iBook has shut down, the adapter makes a quiet, high pitched squeeling/whooshing noise. My trick of unplugging the adapter for a few minutes makes this noise go away (I know when to plug in and press power button only because the noise has gone).
Otherwise the adapter works fine once the iBook has powered up.
Any suggestions?

I would suggest that you replace your adapter, which obviously has problems.
It could be a capacitor in the adapter burning up, and there is a possible risk of fire.

Is the "Apple Composite AV Cable" for Ipod touch a charger or power adapter

What I mean is that if it's plugged in all the time while playing it (on my stereo), is the battery being used (charger) anyway or is it directly getting the power from the power adapter therefore not using the battery therefore not using/draining the battery cycle (as a battery as a limited number of cycles in it's life). Perhaps it's not a charger/adapter thing but a Ipod Touch conception thing. If I use 24h a day the adapter, am I using the battery cycle or not? Who can answer me this for sure (Apple?)?
Also on a similar note, can I connect the Ipod touch on another PC to charge it (through the dock/USB cable) but without synching it (I know only one PC can synch but if I want to recharge the Ipod at my girlfriend's place on her PC without Itunes can I?)

Anyone else has an idea on the issue of if the Ipod touch uses the power adapter/charger as direct source of power and not through the battery? If the battery is now fully charged and the Ipod is playing (and plugged in) is only the adapter working or is also the battery?
remember the good old days when electronics could work with the adapter or the batteries of the time (non-lithium). If you didn't have a battery in it would work. Even if you did have a battery in, the adapter would be the source. I currently have a 20g Iriver and it displays a "plug" symbol when plugged in and playing and not the battery symbol which lets me to believe the battery is not being used.
I am concerned that if a lithium battery as lifetime of 500 cycles for example, and I use 5 hours a day the player (plugged in all the time) that 1 cycle will be done within 5 days even though I wasn't actually away from the power outlet. Of course I will use my Touch often away as well but overall by using 2h a day away and 3h a day plugged in, if it's the battery working all the time, my battery lifetime will be decreased by a lot.
Any ideas? Any way to ask Apple officially? email address? form they will respond to?

MBP power adapter

I have noticed that lately, after I got my new battery from Apple, (it malfunctioned and I got a new one under warranty), that my power adapter has gotten louder and louder with its buzzing noise. I told Apple about it before I received the new battery, and they said that it was normal, but I don't think it's normal anymore. What can I do about it?

If you already contacted Apple about it, there's little you can do about it. If you have brought it into your Genius Bar and they have said it is within normal limits, there is nothing Apple will do about that.
You can purchase a new one, or a used one on eBay or the like.
For the record -- I administer about 15 MBA's in my office, and not one of them makes any sound in the power adapter.

HP Docking Station EN488AA - part number for power adapter

Hi,
I have a HP Compaq nx8220 notebook, with a HP Docking Station (EN488AA).
Unfortunately I have lost the power supply for the docking station.
I still have the power supply for the notebook itself (393955-001) but it does not plug in to the docking station. It is the correct voltage but only 90W instead of 120W, and the connector is the wrong size.
I've been looking online for the part number for the correct replacement power supply for the dock, but became very confused when I found sites advertising the same replacement part for both the nx8220 and the EN488AA when clearly they are different because the plugs don't match. None specify the plug size so I don't know which is which.
Can anyone help me identify the correct replacement part? Or better still, is there a plug adapter available so I can use my existing power supply for the dock too?
Attached are two photos - the plug from the power adapter next to the inlet of the notebook (fits) and the dock (doesn't fit).
Thanks,
EddieD97

The pin in picture looks liek a 5mm pin and one one on docking station is a smart pin. So you would need something like the one in picture in this link.
In the picture observe the component in left hand bottom corner.
http://www.amazon.com/HP-power-adapter-airplane-DV574A/dp/B0006VX07I/ref=pd_sim_sbs_pc_11?ie=UTF8&re...
I would say, take the adaptor to store and get one.
Wish you luck,

Macbook pro with retina display power adapter popped / exploded!

I was just charging my macbook pro with retina display when a loud "pop" noise came from the power adapter and the red light on the magsafe2 connector went out. I unplugged it all immediately, but there was a burnt kind of smell and bit of black 'sooty' type material around one of the edges of the adapter!
Thankfully the rMBP appears fine.
I actually just got a replacement rMBP as the other one had a small scratch on the body. So both the charger and the rMBP that was atached at the time of the pop, will be returned in a few days anyway. Still I am a little alarmed by it all. The charger was plugged into a 6-way extension adapter with surge protection, so I don't think it was a power surge. And anyway my tv (also plugged into the socket adapter) was on at the time and there was no problem there. Can I assume it was just a fault in the adapter? I will tell them about it of course when I call up tomorrow to arrange the return. I just hope the same isn't going to happen with the new rMBP and charger!
Has anyone else suffered a similar "pop" and broken adapter?

Apple's warranty IS international. You have a one-year warranty when you buy the machine and you can extend that - and your phone support - to three years by purchasing the AppleCare Protection Plan, which is international as well.
Good luck with your new computer!
