Spinning noise when power adapter is plugged into pb

when I plug my power adapter into the powerbook, i get a noise smilar to a hard drive spinning. Unplug it and the noise is gone.
Any ideas?

I too have periodically experienced a strange noise (spinning/hissing/scratching) coming from the area where the power adapter cord plugs in to my powerbook. The sound is louder than my HD activity.
It happens only after plugging in the power cord while the computer is on with a semi-discharged battery. If I shut the computer down while it is making the noise, the sound level decreases durring the shutdown and becomes very quiet when powered off (possibly stops). The noise also stops when the cord is unpluged with the computer running but returns when plugged back in without restarting the system.
This does not occur every time I plug in as described above.

My computer's power adapter is plugged into a power source, yet the indicator light is not working and my computer is not being charged.

I have the same issue.
The magsafe goes orange for about 20 seconds, the battery shows 0% then it goes to a black X indicating no battery installed.
With a new battery the same happens, although it can run on battery but does not charge.
It runs fine on mains power, the green light is always lit.
I have tried several things so far:
1. Cleaned the magsafe contacts on cable and macbook
2. Reset SMC and PRAM
3. Installed latest battery update
4. Tried new battery
5. Put old battery in fridge for an hour
I work in IT and am fairly confident taking it apart, what should I try next?
Some people recommend a new battery connector, which doesn't seem to make sense as the battery has never been removed before. Also some people say it will need a new logic/motherboard.
Any experts here managed to sucessfully fix one of these?

Macbook Shutsdown when power adapter is plugged.

Hello,
My Macbook (Jan 2007), is not charging. when i plug the magsafe it goes off. The charging lite turns green just after few seconds, it does'nt stay orange. I have tried everthing resetting SMC, PRM, changing battery etc. Does anyone have any clue, as to why is this happening. I hope its not anything to do with the Logic Board, i guess not, checked the HD other stuff-just don't what to do. Macbook is dead, no way to put in on. Would appreciate any suggestions. Thanks

Macbook pro turns on when power adapter is plugged in

Sometimes my macbook pro (early 2011), turns itself on when i plug the power adapter is plugged in, and the screen is black and unuseable and I have to hold down the power button to turn it off. Then i turn it back on and all is fine.
It does not happen all the time and I believe it has something to do with my power on schedule (my computer turns itself on at 2:00am and turns off at 7:50am) however it still turns on if the power adapter is plugged in after 8am
Just wondering if this happens a lot or my hardware is dodgy? (has happened on 10.7, 10.7.1, 10.7.2)

+I always power down my mac mini when not in use and then turn off the surge protector. ... Also this keeps resetting the internal clock.+
Since you have done this as a habit and it is an older machine, I suspect the "watch battery" inside the Mini that powers the Mini's pram needs to be replaced. These seem to get depleted faster when Minis aren't connected to power full time.

Battery status showing "not charging" when power adapter is plugged in

I just bought a brand new Magsafe adapter 60w for my macbook but it seems that when i plugged in to my macbook, the battery status showed "not charging". I have to disconnect and plug in again. This also happened when I used my previous power adapter, that is why I got a new one. Is this a common problem? Please advise what could be done.

Hi
Try resetting the SMC. This sometimes solves this type of problem, in fact, it's listed as one of the reasons why you should try this:

Battery not charging and makes weird noise when power cord plugged in

I have an issue that a few people have mentioned here, my PowerBook won't recognize when a power adapter is plugged in. I've bought two power adapters recently (that I probably DON'T need now) so I know it's not a bad adapter.
For a few months it has been switching back and forth between wall and battery power but usually only when I was really working the machine either video or photo editing but it has been getting worse.
The thing that is happening to me that I haven't seen mention is my computer makes a fast ticking noise when it is plugged in. Once I unplug it, it stops. And while it was off and plugged in the computer was making a weird whistling noise.
Is this a bad DC/sound card issue and does Apple still do these types of repairs at a Genius Bar or am I on my own?
Thanks for any and all help.

I know exactly what you mean. My 17 inch PB has been quite "noisy" since I received it, but i wrote it off (I was too ecstatic that work bought me a PB). Just recently the sound has been getting louder. I'm starting to think the sound was actually electrical interference that was being picked up by the speakers. Actually today I was in a meeting (speakers still working) and the squeeling sound was getting louder (almost embarrasing loud considering I'm the apple diehard in a pc dominated office). I decided to reset my computer (not something I do often)It seemed to subside for a bit.
Well today, it looks as though my speakers have died on me. I'm not getting any sounds out of them. I'm not a newb when it comes to macs (been using macs since os9, about '99) so I've tried everything I can think of to get the speakers to come back. I believe I'm experiencing a hardware failure (reset many times, check all settings).
Hmph.....Pretty frustrating. No iTunes during work makes me sad. I'll have to check and see if my external sound still works tomorrow.

Why does my macbook only turn on when the power adapter is plugged in?

The battery life says its at 73% and climbing but whenever I unplug my power adapter the mac automatically shuts down and if I try to turn on the macbook without my power adapter plugged in, it wont turn on. How do I make it go back to where I can turn the mac on without it being plugged in? Thank you for your help!

I would try two things the first being resetting the System Management Controller:
1) If the computer is on, turn it off.
2) Disconnect the AC Adapter and remove the computer's battery.
3) Press and hold down the power button for 5 seconds and then release the button.
4) Reconnect the battery and AC Adapter.
5) Press the Power button to restart the computer.
If that doesn't work I would recalibrate the battery.
To calibrate the battery:
1) Plug in the MagSafe power adapter and fully charge the MacBook or MacBook Pro battery until the light on the MagSafe connector changes to green and the Battery icon in the menu bar indicates that the battery is fully charged.
2) Allow the battery to rest in the fully charged state for two hours or longer. You may use your computer during this time as long as the power adapter is plugged in.
3) Disconnect the power adapter with the computer on and start using it with battery power. When the battery's charge gets low, you’ll see the low battery warning dialog on the screen.
4) Continue to keep your computer turned on until it goes to sleep. Save your work and close all applications when the battery's charge gets low and before the computer goes to sleep.
5) Turn off the computer or allow it to sleep for five hours or longer.
6) Reconnect the power adapter and leave it connected until the battery is fully charged. You may use your computer during this time.

I would prefer to answer in your post. as I have tried on two occasions to help.. so far this is the first time I can see you stated you are using Lion.
1. Did you download and install the 5.6 utility..?
I said to do it.. you never said yes.. I did that.
Please do it. .. you will get no place before you do.
2. Did you bridge the TC.. ?
If so it will work perfectly.. please post a screen shot of the summary page from the 5.6 utility. If something is wrong I can work it out from there.
3. Or ring apple support and get them to walk you through the setup.. there should be phone support for the first week or two.

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.

2009 Macbook Pro's fan spin faster with power adapter plugged in?

I was playing restaurant city on facebook with macbook pro with the power adapter plugged in
( a flash game)
after a while, the fan starts to spin faster and faster and made noise, and the body of the laptop starts getting hot too.
However, when I play the game without the power adapter, the laptop stays more quiet, and the i can't hear the fan spin anymore...(which sounds good)
but what i am worrying is that, is the hardware SUPPOSED to get hot and the fan is supposed to spin faster? the reason why it is not is because the computer recognize the power adapter is not plugged in, so it forced the fan to stay at a lower rpm to conserve power? (which do harm to my hardware?)

Hi
that sounds normal to me - charging the battery produces heat, which must be removed via the fans.
They didn't run slower to conserve power, but because they weren't needed to remove the heat by=product of charging.
Flash is a real cpu burden.
