Ibook Power Supply 45W or 65W?

I recently bought a used ibook G3 800Mhz. Runs great. The Power supply that came with has a mismatched cord and a is a 65W model. The battery does not charge. Do I need a 45W power source? It seems so from the knowledge base information that I read. I am probably going to need to replace the battery anyway but I don't want buy a new battery and ruin it.
Any suggestions?

The mismatched cord may be a problem, but either a 45-watt or 65-watt adapter works fine with the iBook. If the adapter is powering the iBook now, chances are there's nothing wrong with the cord.
The iBook will only charge the battery with the necessary power, so you don't have to worry about ruining the battery with an over-powered adapter.
You can read Apple's suggestions for maximizing the life and lifespan of the battery in this article:

Good luck!

LaCie DVD-burner and iBook power supply problem

Hello guys!
I bought recently external LaCie DVD burner (USB). I experienced problem connecting it to iBook. It suppose to be possible to be powered up from USB but only possible way to power up burner only via external power supply. Is there is any possibility to adjust power in iBook so burner will work. I'v checked possibility to use it only powered form USB on MacBook of my friend - it works smooth only from single USB...
Thanks for any suggestions,
Ivan

90W Power Supply recognized as 65W Supply.

I got a new 90W Power Supply for my SL510. But from the PowerManager, as well while in the booting phase, it is recognized as a 65W Supply. ( I get while booting the message to use the shipped supply instead of this weaker one, in the PowerManager i get : "65W AC Adapter is attached")
Is there a way to tell my system that the supply is a 90W unit ? Is this new supply maybe already broken ? How does my computer tell which adapter is attached ?
I already updated to the latest Bios, but it did not do much.
Solved!

If you bought the adapter directly from Lenovo I would recommend you to contact your after sales department for further troubleshooting. It is possible they may need to send you a new one.
You should be able to find the after sales contact information from Lenovo's German shopping site under contact information. Here is the link to the the US site: http://shop.lenovo.com/us/landing_pages/contact/

Using 12V DC to DC converter as iBook power supply in car

I've built a power distribution box for my 12 volt accessories in my car. I bought a Carnetix DC to DC converter to power my VGA touchscreen connected to my G4 1.42 ghz iBook. It can also provide stable 12 volt power for a laptop, with settings of 18, 19 or 20 volts.
Anyone know which voltage to set the converter at, or if this will even work? I've searched the forum, but I can't seem to find a clear indication of the voltage needed for the iBook.

Hi David,
Welcome to the Discussions.
The iBook power adapter has an output of 24v @ 1.875 amps. I think you would be better off using a 12v DC to 120v AC inverter along with the power adapter.

Is the 65W power supply killing small laptop hard drives?

Apple is NOT shipping 45W power supply units to my country (Costa Rica) and the authorized resellers are selling 65W power supply units to PowerBook 12" and iBooks owners, saying that older and smaller laptops can use the 65W unit without problems.
In 1 month, 3 of my friends have lost their powerbook 12" hard drives, all of them were using 65W units.... is it possible that the 65W unit is damaging the hard drive?
Apple documents don't mention any kind of problem related to using the wrong power supply, but doesn't say it's ok either.

Well the authorized resellers are the ones you should
take this up with. If they won't listen, call
AppleCare. Computers are particularly sensitive to
power supply variations. Here is one article which
the resellers should read:
http://docs.info.apple.com/article.html?artnum=75448
I actually printed that document and went to the store to show them they were selling the wrong adapter, but they said Apple is no longer sending/selling 45W adapters to them and they said also that Apple gave them a memo saying that 65W adapters cause no troubles to smaller laptops.
As you can see in the article there's no warning about using wrong adapters.
Hard drives shouldn't be affected by power supply
variations, and given the fact the computer only
takes as much power as it needs, you are more likely
to have a problem putting a 45 W adapter in a 65 W
unit than vice versa.
Even so, your friends could have all lucked out and
gotten a single bad batch sent to Costa Rica.
Yeah, this is absolutely possible, but what are the chances that the three laptops using wrong adapters had hard drive problems?...
I basically want to know if this is happening on other countries (the "no 45W adapters" thing) and if also the hard drive problem could be related to the 65W one.
Regardless, what happened to their original adapters?
One guy lost it on a trip to the beach; the cable that goes to the computer was broken on the other two.
Thanks for taking time to write this answer!

Registering a 65w power supply? Where? How?

Just had not one but TWO G4 17'" powerbook power supplies go dead on me within the span of two weeks. The first one shorted out totally and left charred plastic and burn marks right where the cord the plugs into the computer meets the power brick. However the second literally caught fire in front of my eyes!
I was working on my laptop when suddenly everything shut down. I was confused at first but then I noticed the burning electric smell. When I glanced down at the power supply I saw blue sparks and tiny flames coming from where the cord meets the brick (computer side). I immediately unplugged my laptop first and then killed the power surge strip. The cord was totally burnt to a crisp. Gnarly...and good thing I was home when it happened!!!
Anyway, took it down to the Apple store where I got surprised looks from the staff but long story short my applecare was expired and they didn't have any 65w power supplies to "swap out" with me since all the new books use the 85w standard. Needing my computer desperately, I swallowed my bitterness and plunked down the $90 to get a new power supply. (Personally I find that price outrageous...especially since I recently had a problem with a LaCie drive and they sent me a new power supply free of charge without any hassle whatsoever!)
So I am using the one cord to power the two machines currently and I tried to register the darn thing in case this one decides to ignite but on the registration page I can't find any product listing for the power supply...or other apple peripherals for that matter. Its funny too because the Apple store staff made a huge deal of telling me to register the plug and I can't find a way to do it. I own many Apple products and they are all registered but it seems I am lost when registering something simple like a plug.
Can anyone out there help me or provide a link?
*I tried the normal registration link and there is no category for this product.
thanks!

yeah, I figured I would simply call AppleCare or take it back to the store and have them explain how to register online...since they said I could specifically register the power supply online.
also just to clarify things, the cords were not damaged but they were 3 years old. the litlle plastic flange nubs that are near where the cord from the laptop enters the brick were still intact. in fact, that is what MELTED and got all crispy and black. it seemed to me the problem was that the plug was somehow damaged INSIDE the plastic sleeve right where it entered the power brick.
I agree to never wrap the cord around the brick though. One thing that I must say to people who bought the G4 17" books when they first came out and are still using the same power supply, please take note of how hot the brick gets. Right before all this grief happened I started to notice that the brick was getting VERY warm (dare I say hot?) to the touch. I never once noticed any physical damage to the wires or connector...as far as I was concerned the power supplies were slightly less white but there were no visible signs that they were going to ignite.
At this point it is too dificult to determine the factors that may have caused both power supplies to catch fire, so I won't speculate. However, my new power supply is plugged into the same outlet as the other two and working fine. It is also much much much much much much cooler to the touch than my old power supplies.
My advice: if your G4 powerbook power supply is too hot for you to hold it in your hand it may be time to take advantage of AppleCare and trade it in for a new one OR go to your nearest Apple Store and plunk down $90. Your choice!

45w power supply getting hot

When I plug my 45w power supply into the extended cable it brick gets incredibly hot. When I plug it directly into the wall with the 2 prong plug it does not get as hot.
Any suggestions as to what is going on?

It will also depends on WHEN you are checking the brick. If you check the brick after say, you have been watching Netflix movies FULL screen for the last 2 hours, it will likely be more hot than it would if you were just surfing around the internet. Also, it would be warmer if it was currently charging the battery as opposed to JUST powering the computer. It shouldnt matter if it is the long cable or the direct plug. Last, define HOT? What you consider HOT may not be hot at all to me. It is a completely subjective thing. Obviously if it is so hot that you cannot touch it, that is a different story.

45W or 65W power adapter for T440s

Which is the correct power adapter for the T440s....45W or 65W adapter that Lenovo is selling under the accessories section? The websites pulls up both adapters for the T440s. The 45W adapter output is 20 volts, 2.25 amps and the 65W adapter is 20 volts and 3.25 amps. Is one adapter more recommended over the other? Are their pros or cons to either? Does one charge faster but reduces the battery life?

@sjahanmi,
Parts list for T440s -> http://download.lenovo.com/parts/ThinkPad/t440s_fru_list_20130724.pdf
I will recommend calling the call center to get the recommended AC for the laptop.
Which AC did your laptop came with btw?
For mine I had the 65W for my T420 however one of my colleagues had the 90W one, its also usable however it seems like their laptops charge faster than compared to mine. I am not sure if its a placebo effect or it does charge faster.
I think the best way for you is to contact the call center and provide them with the machine type and they will recommend you accordingly.

I have a Y2P (i5) ... Feel free to ping me if you want me to test some applications with your Y2P if you have the same model. I don't mind keep doing recovery on it if needed .... =)

Ibook G3 power supply

Will the 65 watt power supply apple sells work with the ibook G3 900mhz white 14.1 inch computer?
I need to replace the original one after 3 years, and all I can find is this one. In reading the small print on the two units, the only difference I can find is in the number of output volts. The 65 watt model puts out 24.5 volts and the 45 watt model puts out 24 volts.
Will the 65 watt model with .5 extra volts damage my computer?

Hi, and welcome to Apple Discussions.
I'm not certain whether you can replace just the cord, but there are less expensive replacement adapters, such as the one at batteryheads.com.
A Google search may find others.
Also, you may want to try posting in the iBook (colors) Forum.
You have posted in the iBook G3 (Dual USB) Forum (the forum for the first all-white iBooks).

IBook G3 M6497 - What Power Supply?

I got a free iBook G3 Dual USB, model M6497. The catch was that it did not come with a power supply, it had been in a closet for a few years and the owner doe snot remember where it was left X years ago.
Anyway, what model power supply do I need?
I know a guy with a M7332 yoyo, but I that one has a different tip, am I wrong and it will work?

Hi, and welcome to Apple Discussions.
It takes this one:
http://store.apple.com/us/product/M8943LL/A
Some of the older yo-yo type adapters have the correct size tip, but some do not. I would advise buying the newer style so that you have the colored light ring which tells you when the battery is charging and when it isn't.

Dead ibook after replaced power supply

i'm trying to fix my mom's ibook for her. it hasn't powered up in a few years. apparently, she took it to a guy of questionable skills and he replaced the power supply. it then worked for a few weeks and died again. my question is this: could he have installed another bad power supply, or could something else in the computer be killing the power supplies? is there anything else i could try, like resetting it, to make it start up?
more details: the ibook has a brand new battery in it, and resetting the PMU has no effect on the machine.

I don't know what you mean when you say that he installed a power supply?
The power supply of an iBook is an external power adapter which plugs into the adapter port on the side of the iBook.
So, what do you mean "he replaced the power supply"? Do you mean he replaced the power adapter? Or did he replace something inside the computer? If so, could you tell us exactly what he replaced?
What is the MHz rating on the iBook? Which type of optical drive does it have? Which version of the OS is installed on it? How much RAM is installed? Do you know the hard drive capacity and how much space remains available on it?

Will a 65w power supply work with the HP Envy 15t (which comes with a 90w)?

I have multiple extra 65w power supplies from previous machines. The pin that plugs in to the machine is different, but there are converters to get the right size pin. If I get that right pin, is it safe to use a 65w power supply with the HP Envy 15t, which came with a 90w supply?
One supply (65w) says the output is 19.5v, 3.34a. Found another extra (90w) says the output is 19.5v, 4.62a.
The one supplied with the Envy says (90w) 19.5v, 4.62a. I'm assuming with a pin converter, I can use the second one above?

Hi,
For the 65W, It will work, BUT check the tip/connector. The only problems: battery charging could take longer time and for high graphics task it may display an error message. For the 90W, again pin/connector is the main concern.
Regards.

Product counterfeiting Apple Power Supply 65W

Hello,
yes, I know, I was crazy but I bought I Power Supply by ebay. It was declared as 100 % Orignal Apple Product. I beleive that is a fake, because it going on very hot within 2 minutes. Than it stops charging. After 5 minutes it continues similar. My old on delivered with my PowerBook don't get hot.
Does anybody have an idea, how could I find out that this is a fake.
Thanks
Walter

The offered article was declared as an original Apple product.
And it may be one, for all you or we know. There's no foolproof way to tell. But it doesn't work, and that's the basis on which you have every right to expect the seller to take it back and refund your money. Unfortunately, the seller may be unscrupulous and fail to do that, or you may be unable to locate the seller, or the seller may not respond at all, in which case, too bad. Use Ebay's reputation system to register your protest, for what it's worth. I don't happen to think it's worth much, since any vendor can pay any number of shills to provide positive feedback on any number of fake purchases. That's why I tend to avoid shopping on Ebay for anything that can be obtained from a known reliable vendor.

Need new power supply

ok heres the problem. I have a new apple i book g4(12INCH) and i have lost the power cord and i have a generic power supply and it has an output of 30V will it work with the laptop?

The apple power supplies are 45w, not 30w. So your power supply is goning to be under powered.

Power Supply Isn't Charging the Battery

This is a rather tricky issue. It's happened before, a few weeks ago, but it had seemed to work itself out and began functioning normally. As I was playing Neverwinter Nights today, the iBook went to sleep. I had the Power Supply plugged in whilst I was playing, assuming that it was charging the iBook. As it was going to sleep, I would try to wake it up only for it to sleep again after a few seconds. I managed to save and exit the game, and I noticed it's at 0%. So I unplug the adaptor and replug it. It continues to go to sleep, so I shut the iBook down.
After a few hours of fiddling with it and checking for information online on my iMac, I managed to get it to charge to about 15%. At this point, I turned the iBook back on and tried to get it to continue charging, but it's slowly been working its way back down to 8% or so ever since.
What's strange is that the 'ring' on the plug lights up as Orange, but it doesn't charge. I've noticed if I leave the iBook and Power Supply plug alone, the charge indicator will sporadically change between 'Battery Life Indicator' to 'Battery Charge Indicator'. It's not like it flickers between the two, but every few seconds or so, it will change from one to the other, but it still steadily drains the battery. I've tried resetting the PMU, but it doesn't seem to have done anything with the situation. I also tried to diagnose if my Power Supply is bad by reading Apple's information pages on it.
One of the troubleshooting documents shows images of bent metal rings on the connector. I looked at mine, and the metal ring is separated at the tip ever so slightly, nowhere near as bad as in the images. I can't figure out what's wrong. Could anybody give me some help?

I have the very same problem - you could try someone else's charger if possible
did not work for me though
If you get any luck could you forward the reply to [email protected]
cheers
Jason
