New power adapter fail

My friend lost my original power adapter and she bought me a new adapter, however, this adapter causes me lots of problems-it works sometimes, but often I found it failed to work(the light is off, doesn't charge at all), you never know when it is gonna work, I wondering if the adapter has defect?

there was an SMC update for that.

HP Officejet Pro 8500A Plus AC Power adapter failed. Where to buy?

My AC power adapter failed. Where can I purchase a new one in Doha?

There should be an electronics store near there. Go into google maps, bring up Doha, then search nearby and put in 'hp printers' which should be up some sort of electronics retailer.
If that doesn't work, then go to HP.com, put in your printer model, and follow the links, and you should be able to order one online. Just make sure you specify your region in your search, so that it doesn't think you are in Ireland, when you are actually in Qatar.

New Power Adapter Issue

Okay, this is going to be kind of long, I apologize.
So, I have a Macbook Pro that is a few years old (it's the last model to have the one button). Recently, by original power cord got frayed and stopped functioning, so I got a new one. I got the new L-shaped adapter and I started having issues. If I unplug it and plug it back in a few minutes later, it doesn't recognize that it's plugged in. But, if I shut down the computer and take out the battery and put it back in, it will start working until I unplug it again for an extended period of time. The cord works fine in my sisters computer, it's not a battery issue(got a new one after this problem), I reset the SMC, so the next thing on my list to check is the logic board. But then something occurred to me that I should have thought of earlier. What are the odds that my logic board will fail exactly the same time I bought a new power adapter? I think there is something different about the power adapter that is causing issues the SMC or something. Is this what's going on? Are there other reports of this happening? Is there going to be an SMC update to fix this?

The new adapter with the angled plug doesn't work with older (pre-unibody) MBPs. If I were you, I would return or exchange it for one of the older ones with a straight plug. If you can't exchange it where you bought it, ask for a refund, and buy a new or refurbished adapter from one of these vendors:
http://eshop.macsales.com/item/Apple/A1290AR/
http://macbookadapter.com/85wcompare.html
The first is a highly dependable Mac-centric vendor with whom many regular posters here have dealt often and happily, including myself. The second is a vendor I've never dealt with and can't vouch for. I mention them only because they advertise old-style MagSafe adapters both new and refurbished. Before ordering from either of these or any other vendor, telephone them and confirm that the older style is available and will be supplied to you if you order.

Need new power adapter for Qosmio F50

Hello
I am in need of buying new power adapter for my Qosmio F50 126. The reason being if I try to run more demanding application on my computer, the entire computer just crashes, shuts down. I need to buy a new adapter before my entire computers crashes result in destroying my HDD. I am not sure if my battery are died or the power adapter fails to charge them up.
The picture of underside of my power adapter is shown below.
https://www.dropbox.com/s/qcrk4fl5bhftbzm/IMG_20131220_215821_454.jpg
What I would like to know if the following two adapters are the same and would work with my model. I ask this because the price difference between the two units is significant., 20 USD. Also, I will be importing it from the USA using an agent here. Therefore I need to get it right on the first try.
I'm curious about the connecter it has on the end. I wonder if its same as the one which came with the notebook. I believe it wont be an issue with it clearly says it supports my model, Qosmio F50 126
Another find which I believe is the best and most compatiable.
This one will sure work but the price is much higher than the one mentioned above
Regards

Hi
You need an AC adaptor which supports *19V and 6.32A*
The Ampere value might be a little bit different. This should not be a big problem but you have to ensure the Ampere value isnt too low. The notebook needs enough power to run properly and to charge the battery.
However, the Volt value (19V) cannot be different. _It has to be *19V_*
The original AC adaptor has the part number: *PA3290E-3AC3*
I recommend you to purchase the AC adaptor recommended by Toshiba.

New power adapter and battery, still not working?!

A couple days ago, my macbook stopped charging. The power adapter was plugged in, but there was no indication that it recognized it or was charging, so I figured it was a broken power adapter. I bought a new one, plugged it in, everything was fine - until the next day. The new power adapter stopped working as well. So, I go to the genius bar, and they tell me it's my battery. I buy a new battery and plug in the new charger. Everything's working again, until I unplug the power adapter to move my laptop into another room - and now it's not charging again! I tried every power outlet, and something is definitely wrong with the macbook itself. I'm pretty frustrated since I've now spent $200 on new stuff and the problem still isn't resolved.
Does anyone have any ideas?

A, I love Alexia Potatoes--I think I'm having some garlic mashed with dinner tonight.
B, Have you downloaded and applied this firmware update?

Before you do so, you may want to try just a plain old SMC reset:

New power adapter for old macbook - It doesn't work!

Hello!
My MacBook is 3 years old. My power adapter got broken at the end where you put it into the socket.
Now I bought a new power adapter. The adapters have changed now. The end where you put it into the computer looks now a little bit different. But they told me in the Apple Store that it will also fit my 3 years old Macbook.
At home it really fit my Macbook but it didn't charge. Nothing happened, no light. How can that be? Then I combined the two, the end for the socket of the new power adapter and the other part where you put it into the computer of my old power adapter. Now it charges. So is the problem after all the part where you put it into the computer of the new power adapter that looks different now?
Or what can I try now?
Thank you for help!
Sorry for my bad English.

Could I have got a new power adapter for free?

My power adapter for my mac stopped working recently and as far as I know I didn't cause any damage to it myself.
I read the following on the apple website:
Additional Information
Whether your product is in or out of warranty, you can take your adapter to an Apple Authorized Service Provider or Apple Retail Store for evaluation and replacement if necessary. Pending the results of evaluation, you may or may not be eligible for a replacement adapter free of charge. Signs of accidental damage would negate any coverage. Be sure to bring in the computer used with the adapter; it is required to process potential adapter replacements.
Which seems to suggest that even out of warrenty, if the charger has broken of it's own accord you can still get a free replacement?
I took my adapter and mac to the shop, they said there were no signs of accidental damage but said I still have to pay for it. I referred to this statement from the website but they were very dismissive and kept saying it was out of warrenty. Perhaps i'm reading the statement wrongly.
Just wondered if anyone could clarify :-)

As you indicated, it depends on the results of the evaluation.
Apple takes responsibility when design faults cause certain failures, especially when it represents a safety concern. There have been a small number of cases where failure met certain characteristics that Apple deemed that it should not have happened, regardless of age or use.
I am reluctant to indicated the specificity of some of these issues, because for many reasons Apple would not want us speculating on the subject. Suffice it to say your product failure may not have met any particular characteristics associated with failures deemed to have extended coverage.
If your product failed for an unknown reason, or apparently a failure stemming from age or normal life expectancy use, and it was after the normal expiry of warranty, then no further consideration was given. You need to buy and pay for a new one, unless you yourself, can provide extenuating circumstances to consider.

New Power Adapter Doesn't fit right

The power adapter for my iBook G3 started only working when it really felt like it, so I check the discussion boards about buying a new one. I saw the link about Shentech.com, which indicated their power cord was the same as the one bought from the Apple Store, though it cost about half as much. I bought this one, but when it arrived (it was delivered VERY quickly), I was concerned because I have to force it into the computer. It charges the battery just fine, but I am concerned about ultimately doing damage to the computer. It is a model A 1036. Has anyone else had this issue? Since I didn't buy it directly from Apple, can I still ask Apple about it, as it is an Apple Product?

Hi, Katie. Welcome to Apple Discussions.
Yes, I have the exact same issue with the 65-watt adapter I bought from Shentech:
http://store.shentech.com/apge24v265ws.html
I thought perhaps it was because I bought the 65-watt instead of the 45-watt that originally came with the iBook. I always keep an extra on hand, and that super-tight one has been relegated to "extra" status. I am always VERY careful any time I plug it in.
If you are very worried about it, maybe you should call Shentech and ask for a replacement. They may be refurbishing them. Even though it says "new" on their website, mine is a bit scuffed, and does not LOOK new.
A call to Apple about it may shut Shentech down if they are selling refurbished Apple products as new, but maybe that would be the right thing to do?
I'm afraid this isn't much help, but it does let you know that you're not alone.

Power adapter light is dim, new power adapter no light at all

My power adapter went dim and wouldn't charge. I bought a new adaptor and this one doesn't light up at all. Any ideas? tried different outlets that have worked for other electonics. Did I just buy a second adaptor coincindentally?

Macbook air power adapter fail?

My 8 month old Macbook Air power adapter seems to have failed. It may appear to work (amber light glows when plugged in) for a while, but it stops working soon after. Is there something that can be done? Is this covered by warranty?

It's still under waranty so Apple should replace it for you. See "additional information" at the bottom of this article.

Hi Marlisa,
#1 Your battery should be replaced if it has actually gone through 1128 cycles. Most batteries don't last near that long.
#2 Reset the SMC

New power adapter dead after one charge cycle

hi guys.....
my power supply went a week or so ago... started to turn on and off then stopped completely...
i bought a new apple A1021 as an exact replacement to the previous...
plugged it in and got amber led then charged through to green and all functionality was as normal... problem sorted.... or so i thought....
came to it the next morning to find no led on.... so i checked fuse and swapped lead etc but no response....
phoned apple store mac docs whose answer was 'ummm i don't really know try resetting the pmu' which i have done but still no luck....
so my questions to you are:
1. is the new power supply faulty?
2. is there a problem with something shorting / feeding back into the power supply.... frying it?
3. is there an internal fault preventing charge / power? (although it did charge once)
4. a friend said it could be a faulty battery?
i don't know if you have come across this before but any help or suggestions would be greatly appretiated.... thanks

New power adapter *****

i donn't know what's going on but it's not charging. It's actually brand new, my last adapter became a fire hazard when wires started poking through around the port (thanks, apple!)...But now that when i plug this one in, with no apps running aside from opera, it's taken 40 mins for 9% charge. I'd say it's a third slower than my old one. Has anyone heard about this? I'm thinking I should try and get a refund, though that will be a headache and a half through the online store.

welcome to macbook forum.
if your battery is completely depleted before you get that mag safe adapter, it will took longer to achieve proper charge level and speed.
try not to use any application is recommended and/or leave it charging over night.
also try to calibrate your battery along with reset your SMC once it fully charge to give you better reading.
Good Luck.

EZXS88W Maybe power adapter fail???

Intermittantly, (0 to 5 times a day) the power light will go off and on with a result of all lights for the 8 ports going off and then all on while it resets and this may happen several times sucessivly. Of course the Computer loses the 100mb connection.
I've metered the Linksys 3.3vdc .3a power supply when it is operating correctly with a Fluke 89IV meter and it indicates 3.5602vdc. I have no way of monitoring the p/s when it fails as the failures only lasts for a second or so.
Switch currently has just one desktop and sometimes two laptops plugged in and it uplinks to a Linksys Wireless G Router. I'm not expierencing data failures that I know of.
Do I just have a defective p/s?

I'm having the same problem, i have a Linksys SRX200.
this reboot like 10 times per day.
