Different notebook power adaptors

HP Pavilion DV6-6138TX, Windows 7 64-bit
I use the included 120W/18.5V/6.5A power adaptor included with my laptop, however, it is quite bulky and often not the best to travel with.
I also have access to the smaller 65W Smart AC Adaptor (spare part # 463958-001), which my laptop recognises and accepts. It does notice that it is a weaker adaptor, and suggests I change back to my bigger one.
However, if I am traveling around (university, for example) using basic word processing functions (i.e no heavy games), is it safe and okay to use the smaller 65W adaptor with me, since it is much easier to travel with?
Thanks, Brandon

Is there any reason why it wouldn't be compatible with the 90W Slim adaptor, or standard 90W Smart adaptor?
Power is calculated as a straight multiplication of (Power) = (Amps) x (Voltage). My guess is that either the voltage or amp setting for those other two 90W adaptors is not recommended for the DV6000 series laptops.
Both the 90W Standard and Slim have an output voltage of 19.5V (4.6A), so is incompatible with your laptop.

By the way, I am aware of possible performance issues/charging time issues with using a lower wattage adaptor, but I am more concerned about problems such as fire caused by the adaptor drawing more current than it can handle, to try keep up with the laptop.
Again, it is not recommended to use the 65W charger. The draw your laptop will place on the 65W charger could cause damage to itself or your laptop from heat as the adapter tries to give your laptop the power it wants.

Power adaptor buzz problem

Just found that my power adaptor make some buzz sound.
The sound come out when charging with my MacBook turned on.
both My MacBook and adaptor make such buzz!!!
However, when I disconnect the adaptor to the MacBook, both power adaptor and MacBook become silent. when I plug it again, they start buzz....:(
I have my MacBook for about 2 months, and the battery "expand" in the first charge(5 hours after my purchase). Have a replacement two days after.
Now the power adaptor got problem.... the service center "CASE HK" tell me to wait 4-6 days until they have replacement part available.
I am not sure if the problem also related to the MacBook, but I have to use it tomorrow, so I only leave the power adaptor.
I want to ask if ther is anyone that face the simular problem? Both power adaptor and MacBook buzz.....
Should I need to send them my MacBook as well?
I am quite disappointed but no choice...
My old PC notebook, a Pentium II 366 still in a good condition(bought in 1997). Battery, power adaptor, HDD.... everything still functioning today.
I just wonder if this Mac will last for one year...:(
I am a Windows user and recently try a Mac, OSX is much much better then Windows XP, but I am tired of travel for hours and take my MacBook to the service center. Wasting time to searching for posts in different forum about the issue. Dealing with Customer Service with limited knowledge about computer. I have to explain what is damaged, and they seems still not sure what to do next, and tell me to wait for a few days. This waste me too much time and money.
Thank You very much for reading... I know it is a long message and waste time to read....
And sorry for my poor English...
MacBook A1181 Mac OS X (10.4.7)

Just live without power adaptor for 4 days....
My MacBook just running out of battery....
No reply from the service center. No telephone and no e-mail received.

Problems with new Mac Book Pro 13'' +power adaptor

Hi there,
I'm new here and first of all I'd like to appologize from my lack of technical language, since my only interesst in computers is that they don't give me problems so I can keep not knowing too much about them.
Ok, so I bought the new Mac Book Pro 13'' exactly 2 months ago cause my old and long travelled Power Book G4 died. I didn't hesitate to spend the money to buy the new one, cause I was so happy with my experience with the old one and in my mind returning to PCs was not even considered.
BUT...I'm not totally happy about my new laptop...from day 1 Safari would just close itself but I didn't give too much thought about it. After this, not only Safari can close up to several times a day, but also iphoto or any other program that I use for work. But that's not all..One day it would take minutes to start running and it would go extremely slow...another day it would start also very slow but also it wouldn't show the tools bar on top or my folders. Another time it would show me, instead of the normal starting page, a page where it would ask me to accept or not a kind of revision for hardware. After so many problems of course I pressed yes...everything seemed normal, then computer started and seemed to be running normal again (aside from this safari and other programs that shut down). Today my computer, when moved, just went totally blank but fortunately I could start it with nor problems after it.
So...anyone knows what the problem must be?? Should I take it to a Technical service ??? and there's another issue...i'm handing in m phD in a week so I can't just be without computer now, and in a week I'm flying to Canada where I also will need my computer for work...what can I do???
And the second problem...the power adaptor from the beginning seemed to act funny sometimes...sometimes charching, sometimes not, I would follow the instructions in the support part and after being several minutes changing one cord for the other, to keep it 1 minute disconnected and so at some point it would start functioning again. But this happened seldom so also I would think it was a protectiion mechanism of the adapter. But, when this is happening more often than not, then it gets annoying. Also I've been transporting it in a careful way since I bought it to find that after only 2 months in the cord (from the computer to adaptor) you can see the internal cable as if there was some cut...a third one seems to be appearing too. I've taken it to the technical support and the guy who was helfpul but also honest said he couldn't do anything for me cause since there were those cuts, he could always be said that it was a misuse of it-an accident and then he would have to pay the replace himself. Well, it's not!!! My old adaptor has been transported in a way less careful way and it's survived with NO problems for 5 years. The material is clearly different from the old cord. This one because it's new, I only need to put it in a special bag air protected. Honestly I don't feel happy to pay 80 € for an adaptor that I don't know if it's gonna last me only 2 months or that I know I can't transport normally. The guy suggested me to ask in forums and to call directly to the apple technical service.
Again, has anyone had any similar problems with the adaptor???

Take it to an Apple retailer and have the computer repaired. It is still in warranty.

Multiple power adaptor failures

I'm posting on here partly out of frustration, and partly in the hope that someone may be able to help.
I have a late 2011 MacBook Pro 13 inch, that up until July of this year (2013), I was very happy with.
However, in July my power adaptor failed. I had a dimly lit LED and when clicking the battery icon, I was told "Battery is not charging", "Power source: Power Adaptor".
I took my MacBook to the local Premium Reseller (on apples advice) and they replaced the adaptor.
The problem re-occured only a month later. Same problem, same advice, same replacement. This happened THREE times, each time about a month since the previous occasion.
These adaptors were treated well. Rarely used in a different location, and kept free of kinks or stresses.
This month, the problem repeated, AGAIN. I took it to my local service centre and this time they diagnosed a logic board failure, and replaced the part under applecare. They also provided ANOTHER new adaptor.
I picked up my MacBook yesterday. The problem repeated itself today.
I am starting to go slightly mad at this point. The most apple will help over the phone is to tell me to visit the repair centre again and hope for the best, but I'm at my wits end now.
If anyone has any idea what the problem could be, please let me know, because I'm really getting nowhere at the moment with applecare.

That a UPS unit would have prevented your logic board failures. Properly designed power supplies do not need a UPS unit in this country. In some third world countries where the power is unreliable on a daily basis with large power swings, they are a must have.
In my opinion, the G5 iMac's were a poor design with inadequate heat dissipation, weak power supplies and logic boards. Most of them ran for years, but an inordinate number of them had multiple failures. The new aluminum models are a much better design with most of the high heat components located at the top of the machine.
I had no hardware problems with my eight year old Dell...but I'm still sticking with Apple because of their superior software performance.
Good luck with what ever you decide...virg

Power adaptor and battery HOT!

This is the message I sent to Apple a few minutes ago. Maybe some of you can have some answers as well. Thanks!
"Dear Apple,
First of all, I would like to kindly express my apologies for using the feedback form to send you some thoughts about my MAC. I did not know who else to address to.
I have bought my MAC in September 2009, through the Apple Store online. It has been delivered in Norway, where I am living in the present.
Unfortunately, I have never been very satisfied with it, due to two main issues.
First, I have noticed a problem with the battery and power adaptor since the very first day. They are both heating up very fast, after just some minutes, and then the mac is really, really slow (even if I have just one open application). I have tried a few times to go to a service provider in Oslo, but they said it's working fine. The first time I had a visit with a service was in the first week after I bought it. Then, when I had this screen problem, so I took advantage and I asked them to check again the battery (they had it for a week or two). They said it was fine. A few weeks ago I visited 3 different services with the same issue - no problems found.
Of course one could say that this is the proper way of working of a mac, but how can a mac work so slow when they all say it is so fast? I have asked around and none of my friends had a similar problem, since they've purchased it.
I decided to write you now due to the fact that a few days ago I had to use a friend's mac for some hours (which is older than mine, a simple MacBook; plus, he uses it much often than me). It was working perfectly! Not at all slow, no heating.
Then yesterday I had my power adaptor plugged in for half an hour - then I saw that the mac was not charging (how come?). When I touched the power adaptor, I literally burned my finger. Of course I got scared as well. I tried to change the power adaptor with another one - it did not get so heat up, but the battery of the mac was still burning, as usual. I used to keep my old PC in my lap, with the mac it was always impossible, unfortunately.
With lots of regrets I am writing this message. I have never felt that I had a 'real mac', like the other friends of mine, although I was so excited in the beginning. I sincerely hope that I am a unique user.
Now I am planning to sell it to someone (I don't think I can get even half of the price now, since it is pretty old) and get back to some usual PC. With all the regrets in the world, again, because some of the features were indeed really cool (like the trackpad, for eg).
Thank you for reading this! Good luck with your future products! And may God rest in peace Steve Jobs, I hope the business will not be affected.
Best regards,
Cristina Moldovan"

45W is definitely not correct for any 15" model. Here are the correct model power adapters:
http://docs.info.apple.com/article.html?artnum=75448
Yes it can hurt and potentially create a fire hazard if you use the wrong adapter. Get the correct one.
As for the display resolution the 867 Mhz TiBook was released on this release as a:
http://support.apple.com/specs/powerbook/PowerBookG41GHz-867MHz.html
1280 x 854, 1152 by 768 supporting display. Check the inside of the machine's battery bay to verify it is an M8858LL/A. If it isn't then this might be a bit of a Frankenmac.

MacBook Pro Hard-Drive and MagSafe Power Adaptor

I have just purchased a 15.4" MacBook Pro (Model number A1150) from eBay. The system was sold as being for spares or repair and because I'm up for a challenge and desperate to break away from my ties to Windows and move into the Mac world I thought I try the 'repair' route.
The system I have is model number A1150. It dates from early 2006 and has a 1.83GHz Intel Core Duo processor. Having opened the case up I found there is no hard drive installed so I need to purchase a new one. I know that the system shipped with an 80Gb SATA hard drive but I don’t have any more detailed information than that. Is anybody able to advise me what make, model and full specification of hard-drive I need to purchase to help bring this machine back to life?
In addition, the system did not have a MagSafe power adaptor so I need to purchase a new one. The technical specifications show that I need to get hold of an 85w MagSafe adaptor, but I believe there are different types of adaptor available now. Could somebody let me know what type of adaptor I need?
Thanks in advance – I’m sure I’ll have some more questions as I hit new obstacles!

Macbook Pro Power Adaptor

I need to order a replacement power adaptor for my macbook pro. The writing on the old adaptor is worn. Cost indifferent, should I purchase a 60W or 85W? Thanks!

Which power adaptor cable?

Hi..I have a BT Relate 2100 home phone and the dog has chewed the power adaptor cable. Can I purchase any telephone power adaptor cable that has a RJ11 connector on one end and a 3 pin adaptor on the other as I can't find one exactly for the BT Relate 2100?
thanks for advice...

No you cannot use any one as the voltage will be different, suggest you check the voltage on the pack you have, if you cannot find a replacement can you not re-join the wires?

Self repair apple cinema display 65W power adaptor?

After a power outage, I have discovered that the 65W power adaptor (A1096 661-3760) driving a 20" apple cinema display is no longer working. A different brick from another display works fine. I was wondering whether I might be able to service this power adaptor myself? Are there online guides for dissembling the adaptor and checking if maybe a fuse has blown?
Thanks for any advice...
Paul

My guess is not even apple bothers to repair something like a power adapter. A google search shows it can be replaced (albeit not cheaply). It's probably dangerous to fiddle with too since you have line voltages to deal with.
You could call a place like Mac-Pro to see what their opinion of repairing it is. They sell that adapter but also repair mac stuff.

What does the power adaptor look like?

Did Apple make any changes to the power adaptor? Is it thinner too? I am waiting a month or two for the 1.6 MBA regardless of changes.

The Mag-safe connector is physically the same. A MBP or MB adapter will physically and electronically work with the MBA. However, since the MBA's port is facing down, you will need to account for this when using an MBp or MB adapter, either by charging the MBA upside down or some other fashion.
the physical size of the MBA adapter looks smaller than the MB adapter, but this will still be unanswered until someone can compare them in person.
The power output for the different adapters are:
MBA: 45 watt
MB: 60 watt
MBP: 85 watt
You can use an MB adapter to charge an MBP, but the battery will charge very slowly.
You can use the MBP adapter to charge a MB. It will not send the full 85 watts.
Apple can not warrant or guarantee no problems when using a different adapter than intended so do this at your own risk.

IPad mini w/Retina, which power adaptor?

I purchased an iPad Mini w/retina about 4 days ago. It came with a 10W power adaptor. The adaptor looks the same as the 12W power adaptor that Apple sells as an accessory, I bought one some months ago at an Apple store to use with my iPhone 5C and was told it would work fine with my iPhone and it seems to. I did not realize the two adaptors were different wattage until I happened to use the 12W with my new iPad and the iPad got/gets very, very warm, almost too warm to handle. The last time I charged I used the 10W and it was much cooler and seemed to charge faster, (that it charged faster may be my imagination). I've checked online at the Apple web site under accessories and I do not see a 10W adaptor for sale. Does anyone know what this means and will using the 12W adaptor hurt my iPad? I am in love with my iPad and don't want to hurt it.

shldr2thewheel wrote:
you can always use a charger with higher wattage, but not a charger with lower than the required wattage. You can use the 12w if you need to, but it would be best to use the 10w charger that came with it.
Why would it be best to use the 10w charger? On the Apple Store site, it clearly says the 12w charger powers every IP made, the mini and the regular ipad, and a host of other Apple gear as well. It's all I use with my IP and my iPad. Much quicker charge than the 5w block (which is only good for an IP, but slower).

Have a C310a that will not start. Have +32VDC from Ac power adaptor, using on a Mac.

Have a PhotoSmart Premium e-All-in-One PrinterC310a, it will not turn on. We have been using it on an iMac and a MacBook, both OS X 10.6.7. Have been thru the HP resetting of the power adaptor etc, so I checked at the printer plug and had +32VDC, which is the correct input voltage. The printer still will not start, what am I missing?

Hey zzzzip! I know its a basic question, but have you tried using a different outlet that you know works? Here is the document on troubleshooting power issues:

If you have gone through all theses steps I would contact telephone support.

Do both of Apple Store's iPod power adaptors work with the new Touch 2G?

Hi,
Many thanks in advance for your attention.
Looking to to get an Apple USB power adaptor for the iPod Touch 2G.
In the Apple Store, two are listed, one smaller (and newer) than the other. In the newer one, the prongs are not retractable; in the larger (older) one, they are.
1. Does anyone know if the larger (and older) power adaptor works with the iPod Touch 2G USB-only interface?
2. I know that many power adaptors and speakers and car adaptor sets, etc. in the past had a combo Firewire/ USB power interface. That is why the new iPod Touch 2G (or iPhone 3G) does not charge up or power up with these speakers and chargers, etc. (Speakers such as the original Bose Sound Dock).
3. Is it true that the older (larger) power adaptor works better in all kinds of power situations (different outlets, etc. in different countries); that the older (larger) power adaptor is more travel-versatile? The Apple store perhaps notes a difference, noting that the newer power adaptor works only with USA-style outlets. I see no such note with the older adaptor.
4. Finally, does anyone know of a USB-only interface that would work with the iPod Touch 2G that is not Apple's (and perhaps not as insanely priced)?

Many thanks for further clarifying.
I don't know 100% for sure that the Apple USB cable for the iPod Touch is different than the Apple USB cable for the iPod Touch 2G.
But:
I have read (somewhere) that the tiny pin connectors are different. That is why an iPod Touch 1G could be charged by (for example) a Logitech mm50 Speaker set and an iPod Touch 2G cannot.
An iPod Touch 2G can still connect to the Logitech mm50 Speaker set. It will still play and you will hear music. But it is no longer charging. And I have read of iPod Touch 2Gs getting very hot in these cradles. That can't be good for the poor iPod in the long run.
So for the Apple USB power adaptors to work, (which both came out before the iPod Touch 2G), they must have some override or blocked pin if they can work with both generations of iPod Touches.

Use power adaptor or battery

When to use which (Macbook Pro)? Use the battery at all times and drain then recharge or just when an outlet is not available?

That was copied and pasted from the article named above under the sub heading "Standard Maintenance". I did read that. But that does not really describe how I use the computer. I do not travel with it much. I use it more like a desktop. I purchased the notebook because of it's small footprint and portability. I use it in various places around the home on a daily basis. Wherever I am there is an electrical outlet handy. If I follow the principal of discharging and recharging once per month then I would be using the power adaptor almost constantly. Is this truly recommended?

Zen Touch AC Power Adaptor Sp

What size (for example .7mm x 4.0mm) is the barrel connector (AC power adaptor? ) which plugs in to the Zen Touch? I don't have calipers to measure it.
I'm trying to purchase/make a car adaptor (hardwire in, NOT a cigarette lighter adaptor) which I will use to charge my Zen Touch while on the road. I know I need to supply 5vDC @ .5 amps (per Creative customer support), and I *think* I found a supplier (Lind Electronics) which has a variety of adaptors - I just need to know the size of the barral connector.
Anybody know, or know where this might be documented (It's not in the Manual)?
thanks
PhilMessage Edited by DirtyDieselPhil on 04-08-2005 2:07 AM

Thanks, SSR - I tried to measure with a ruler, and it's definately 4mm OD. Just wanted to get this back to top for any other input... (anybody from Creative want to chime in?)
What do you mean by "I'm trying to find a socket that's compatible with this..."? I guess you're looking for this connector? I looked at Radio Shack, and they have a ton of different connectors - I was going to give them a look-see.
