brah - you will have a fire and fire hazard !!!!! go look where the wire goes into the connector at the bend right up to the connector. i bet there already is black/ char colored inside of the clear insulation. i bet your short is right there like it usually is with the many other yoyo's. you can grab an exacto knife or sharp sewing scissors and cut it and then resplice it [remember to unplug it first grasshopper]. you can be really classy and solder it the right way, too. then clean it up with some nice 3M brand high quality black electrical tape. if you have tiger you can get into the system profiler and look under power and your 45 watt adapter should be putting in about 50 watts!! otherwise the adapter itself might be faulty. and if you are not sure then please please just throw it away and buy a new adapter. nothing is worth the real risk of a fire!!

Using my macbook pro whole day with the power adapter , will it affect my battery? Please help

Using my macbook pro whole day with the power adapter , will it affect my battery? Please help

It doesn't affect the battery. You can use your MacBook Pro plugged in all the time without damaging the battery. You only have to be sure that you unplug it and run a battery cycle (drain the battery without letting the Mac turn off and charge it fully) at least once a month to keep the battery life.

What is the necessity of the AC power cord (with Mac Book Air)? When should it be used with the power adapter?

what is the necessity of the AC power cord (with the Mac book Air)? when should it be used?

Gary, you wouldn't believe some of the questions people ask on this site.
Why are both cords necessary?
They are not.
Other than the two reasons dominic23 sited are there any other reasons to use the AC power cord rather than the power adapter cord alone?
No.

Is it better to use my Pro with the power adapter plugged in or out?

After charging my MBP's battery to 100%, which is better?
- keep the power adapter plugged in to the laptop and resume using until you want to turn off the laptop
OR
- because the battery is already at 100%, unplug the adapter and resume using until you feel like you should charge the laptop again (maybe around 80%-90%)

If you are convenient to an AC outlet it's fine to use the adapter. However, keeping the AC adapter connected will not have an adverse affect on the battery. Once the battery has been fully charged it will stop charging. Recharge will begin once the battery's charge drops below 95%. LIthium-Ion/Polymer batteries do not exhibit memory effects.

Charge an X220 with the power adapter of a T530?

I have an X220 (which is, hands-down, the best laptop I've ever owned). My wife recently bought a T530 for herself. The power adapters appear to be roughly the same, though the T530 has a significantly larger brick. Are the two adapters compatible, or if I find myself running low on power with only her adapter available would it fry my machine?
Solved!
Go to Solution.

you can use a 65, 90 and 135 watts adapter with the X220. The T530 you got have a 90 watts adapter. The adapter is designed to only supply the current (voltage is fixed) and therefore the power only as needed by the machine. It is not constantly supplying 65, 90 or 135 watts, these are the rated maximum power.

Trouble with the power adapter for 17 inch mac

I have heard that there were faulty power adapters made for the powermac. Does anyone know about this and does apple offer any kind of replacement?

All programs for the PowerBook have long since ended. If your power adapter has failed, replace it.

HT3131 how can i run in clamshell without the power adapter plugged in?

just what the question states..I dont want to have to always connect the power adapter. thanks

thanks this works well with the power adapter pluged into the mac, but I am looking for this exact setup without the need for the power to be supplied to the mac.
in otherwords, run it off the battery only.
I want to think that there is either a preferences setting, or function to be able to do this.
currently it appears that the mac will only run in the configuration with external perpherials with the power supply.

Auto shuts down - could it be the power adapter?

I'm having problems with my first generation macbook lately, it will auto shuts down (not sleep) with the power adapter still attached. And when it shuts down, the adapter still light up green. Im working without the battery, it is removed all the time cos it is dead already.
Could the problem lies with the power adapter? but it's still shows green light, that means there is still power running thru? I would like to test with another power adapter but i don have friends who have a mac. I don't want to spend money one another power adapter, without knowing the cause.
Is it possible to do a test on the power adpater? thanks!

A test you could try (rather than another adapter) is to put the "dead" battery back in and run it on AC. As Gregory said, without the battery, the slightest knock to the magsafe connecter may cause it to disconnect, even momentarily, thus you lose all power and your MB turns off. Hopefully the battery will have enough capacity to allow the MB to stay on (briefly) when the connecter is disconnected for that moment. Just an idea.
Good luck.

Sleep and the Power Adapter...

I have been having iBook sleep problems and here is an example. working on ibook with power adapter in. i close the lid and it goes to sleep but wakes up and goes back to sleep then finally its asleep. ok i click on my mouse and it wakes up. another would be i manually go and click on the sleep option and while the lid is open it sleeps wakes sleeps wakes...finally sleeps. i close the lid click the mouse it wakes up... so i decided to reset the PMU and everything and did the same test and the same things happend. then for some reason i said let me try this with the power adapter unplugged. so i tried it and now the sleep function is perfect. i put it to sleep without the adapter and i press on the mouse and it stays asleep untilll i open it...weird but does anyone know what i could do to fix this when its plugged in? anyone else have this problem? thank you.
iBook G4 14 inch. & Imac G4 15 Inch Mac OS X (10.4.1)

Hello Steven,
I think the reason this is happening is just because of the mouse that is connected to the ibook. I have an external mouse that I connect to mine. When the ibook is connected to the power adapter, it will wake up if the mouse is clicked, because it is getting a signal, and therefore wakes up, then goes back to sleep (when closed) because of the switch inside the computer telling it to sleep. This also happens if you connect something to a USB port. I don't know exactly why this doesn't happen when it is not connected to the power adapter (Maybe to conserve battery power?), all I know is that it just doesn't happen.

You won't need a plug adapter if you buy a figure-of-eight mains lead (like most portable radios etc) with a UK plugtop to replace the original lead.

ZR65MC camcorder does not turn on with battery in position unless the power adapter is plugged in

Bought a ZR65MC camcorder in 2003. Enjoyed it so much, but a couple of yrs. ago, the tape compartment stopped opening. I just purchased another ZR65MC (used) on ebay in hopes that I could at least get the videos off & onto DVDs. Also, we are planning trip to Yellowstone soon, so camera/camcorder will be nice. Problem: The used one does not turn on with a fully charged battery unless the power adapter is plugged in. I assume battery is good because it turns on my older camera. I do need backup batteries in both, but have not done this yet. Please tell me I have not purchased a bad camera, maybe just doing something wrong? Would have never purchased a used camera online, but did this time. I have ordered a new battery BP-522 with wall charger. It should arrive next week. Any suggestions?

Hi Sharon72064,
If the new battery won't power the camcorder without the Compact Power Adapter, unfortunately, it's likely that an internal component has malfunctioned.

Is the power adapter in the world travel kit identical with the one in the world travel kit?

I was told that to charge my Ipad2 in Europe I need to buy the world travel adapter kit - with the apple power adapter that looks the same as the one that comes with the Ipad2 - plus the adapter plugs. I do not need any more adapter plugs - have lots of those and multiple ones for Europe. So why am I being told by Apple store people that I must buy the "kit" for $39 when I already have a power adapter that is 110-240 . I can see taking a second power adapter - in case something happens to the original one- but why am I told that the power adapter in the kit is "different"? If so - different in what way?

To follow up: I'd put my apartment number (there are about five hundred at this address) in my address information (or Apple pulled it in with the information that goes with my Apple ID), but the number didn't make it into the shipping label. Calling DHL got the apartment number added, and they will attempt delivery tomorrow.
So calling DHL was the thing to do. I even grudgingly admit that having me make the call provided the information needed to close the case.
Two residual complaints: Apple/DHL should have formatted the address label correctly. And, DHL should have registered a shipping exception, which should have gone to Apple (or me), so I could have been told of the problem two weeks ago.

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 !
Solved!
Go to Solution.

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.

Doesn't recognize the power adapter. Have replaced battery and PRAM.

Howdy,
I'm having a devil of a time with my Powerbook. It won't recognize a power adapter.
It won't charge my battery.
Won't run when plugged into the power adapter.
The only way it works is for me to charge my battery in my girlfriend's Powerbook and then sprint through any work I try to get done.
I've replaced the PRAM with twice. (one i bought and the other I took from my girlfriend's which I 100% know to work) It didn't make a difference.

My sanity is going on this.

Welcome to the Apple discussions.
There's only 4 components in the charging circuit: power adapter, DC-in card, battery, and logic board. Do you know for a fact that your power adapter is working? If yes, then not running on the power adapter says either the DC-in card is bad (the card that has the jacks on the left side of the computer) or it's a logic board issue. Is the female jack where you plug the power adapter in visibly damaged, loose, or the case around the socket damaged? If the socket is wiggly loose, likely a new DC-in card is in order. Does the power adapter light up at all when you plug it in?
We had a similar, but not exact, situation recently on one of our Powerbooks, and ended up taking it to the Apple store, where they sent it to the Apple depot for repair. They replaced the logic board and put a new battery in. The Depot service returns the machine with anything needing repair, repaired. If everything is in good physical order, ie the case isn't damaged, it costs around $325, which is less than getting a new logic board put in at the store. If the case is damaged, a trip to the Apple depot costs more. A new DC-in card card + installation by Apple runs around $130, give or take. Used DC-in cards run around $75-$95 if you want to install it yourself.
