Macbook VS. MBP power source

Dear all,
My Uncle has just lost his plug/battery for his MBP.Is it possible for him to use the Plug/battery from My Macbook??
regards,
Paul.

Hi Paul,
sorry but no.
The MacBook uses an 60W power adaptor, whereas the MacBook Pro needs an an 85W power adaptor.
Therefor the MacBook power adaptor does not supply enough power for the MacBook Pro.
Sorry
Stefan

My MacBook air's power source is damaged

My MacBook air is completely discharged and the power source isn't working, what do I do?? I have to redefine my SMC but my mac wont connect to the energy...please help!! Thanks

Try another power outlet.
If this does not help, you may have to the computer and the power adapter to the Apple store
to have it checked out.
Best.

My MacBook Pro's power source is draining my RAM.

I've got a MacBook Pro (mid 2010) with 8gb of RAM (just installed new/more RAM last week). For some reason, my power supply seems to be draining my memory. When my machine is connected to its power source, my RAM dwindles down to 10mb. If I remove the power cord, the memory goes back up into the 3gb to 4gb range. Anyone know why this is happening and how to remediate this issue? Thanks in advance.

Don't "calibrate" the battery, that's a waste of time.
While the problem exists, launch Activity Monitor according to the following:
Using Activity Monitor to read System Memory and determine how much RAM is being used (OS X Mountain Lion and earlier)
Make the window large enough to capture as much as possible.
In the View menu, select Active Processes.
In the View > Columns menu, de-select User and make sure that Memory is selected.
Select the Memory tab, and click the Memory column so that the triangle is pointed "down", sorting that column in decreasing order.
What you see should resemble the following:
Post a screenshot (see below) of the Activity Monitor window.
To take a screenshot hold ⌘ Shift 4 to create a selection crosshair. Click and hold while you drag the crosshair over the area you wish to capture and then release the mouse or trackpad. You will hear a "camera shutter" sound. This will deposit a screenshot named "Screen Shot...." followed by a date and time on your Desktop.
When you post your response, click the "camera" icon above the text field:
This will display a dialog box which enables you to choose the screenshot file (remember it's on your Desktop) and click the Insert Image button.
⌘ Shift 4 and then pressing the space bar captures the frontmost window.
⌘ Shift 3 captures the entire screen.
Don't capture or upload any information you consider personal.
Drag the screenshot to the Trash after you post your reply.

MBP power source

I'd just gotten the new MBP and I was wondering if I have the power adapter plugged in, does the built-in battery still run out?

The AC adapter charges the battery, so no, the battery will not "run out" while the adapter is connected.

Where can I get an additional power source for my MacBook Pro?

I am travelling to Europe next week and will be travelling on the road quite often. I would like to get some work done during that time. My laptop battery will inevitably run out of power during that time and I would like to carry an additional power source with me so I can get some extra juice when I am nowhere near an outlet.
I have the latest MacBook Pro where the battery is not removable.
Where can I get an additional power source for my MacBook Pro? I don't mind if it is a 3rd party product.

you could get something like this: http://www.amazon.com/Energizer-XP18000-Universal-External-Netbooks/dp/B002K8M9H C
it's about the same cost as an extra battery used to be. there's a range of similiar products at Amazon, i'd check reviews.

Is there a MagSafe 2 compatible portable external power source for the retina display MacBook Pro?

I’m using a retina display MacBook Pro with the MagSafe 2 connection. I would like to have a portable external power source to extend the use of my laptop on long field trips where I am away from power sources. Swapping batteries is not an option for this generation of MacBook Pros. There seem to be many options for PC’s and even iPhones/iPads/iPods but the MagSafe 2 connection seems to be the issue. I saw one link that suggested buying an Apple MagSafe 2 power adapter and performing surgery on the power cord (using components provided by the vendor) so that the adapter would run on their back up battery. I was hoping for a more esthetically pleasing solution. Any suggestions? Does this product exist and I just missed it? Clearly, if a MagSafe(1) compatible external battery existed I could adapt that using the MagSafe to MagSafe 2 converter.

Sparon,
I wouldn’t recommend using an underpowered AC adapter with your MacBook Pro. It sounds as though the best solution would be to get a different laptop bag with a sufficiently large side pocket.

I have new hard drive in macbook pro(08) and have SATA cable with external power source to old hard drive (10.5.8)via. USB port and newer drive(10.6.8) will not recognize older drive..Do I need to partition newer drive with older disk to recover data?

I have new HD 750GB Hybrid in 2008 Macbook Pro 17" w/ Snow Leopard 10.6.8 connected to old Hard drive(250GB that had 10.5.8 on it at time of failure) via SATA cable to USB port with external power source.. Computer not acknowledging old HD at all in Disk Utility or otherwise (that I'm aware of)..Do I need to partition New HD and load old(10.5.8) onto partition to recognize older drive for data recovery? Thanks Wayno08

You do not need to load 10.5.8 onto your new drive in order for a 10.6.8 system to see the contents of a 10.5.8 system.
You might want to check out the hard drive troubleshooting bootk in the downloads section of this web site:
http://scsc-online.com
They also sell a product named Phoenix that can do OS extraction and volume copying/cloning, but to be honest I don't know if it's appropriate in this case.
I would suggest the following:
Open up Terminal.app (under utilities) and type "diskutil list" without the quotes. This is the command line version of Disk Utility. If the external drive doesn't show up at all, then it's likely not connected properly, not getting power, or just plain dead. If it shows up with only a devce name like disk0s16 but no volume it means the drive is seen, the OS just can't make sense of it.
Assuming the drive shows up, I would try to boot off the original installl disks for the system and run Disk Utility from that. I'm assuming the drive will show up. You'll want to select the option to repair the drive and then perform the option to repair the permissions.
If the unit isn't showing up, as per step 1, try a different USB port. More importantly with your unit, try it on another side of the unit if possible. If you read the book I referenced above, some of those units have I/O boards that are separated from the logic board. If the cable from the logic board to the I/O card goes bad or has problems, which isn't all that uncommon, some or all of the ports on the I/O card may appear to be bad as well. If you use a USB port on another side, it would be routing out of a completely different I/O path, so that's a potential problem.
If the drive is only seen with a device name such as disk0s16, it's likely either the index files are corrupt beyond Disk Utility's ability to see them. The only thing that I think would help would be a product named DIsk Warrior, but I can't guarantee that.
Disk Warrior can be found at:
http://www.alsoft.com/diskwarrior/
The company that I linked in the first link above also makes a product named Scannerz that does HD and system testing. The Scannerz/Disk Warrior combination make a good pair because the complement each other....Scannerz does what Disk Warriror can't and Disk Warrior does what Scannerz can't. However, at this point I'm not too sure getting a tool like Scannerz would be of much use because it sounds like the damage has already been done.
Let us know what happens.

My macbook pro 2.0 early 2011 will not go to sleep with the power source connected. only enters sleep mode when running on battery. Someone did this happen, and it could solve?

Alo, my Macbook pro i7 2 GHz Intel Core i7 (early 2011) will not go to sleep with the power source connected. only enters sleep mode when running on battery. Someone did this happen, and it could solve?

There is no output from that command line? Maybe the pid changed.
I'll repeat what I am trying to find out...
1. You do a pmset -g on the terminal.
2. The output from that pmset should have a line that says "sleep 0 (imposed by n)" where n is some number.
3. The ps ax | grep n is supposed to display what the process associated with n is.
It's the output from step 3 that should indicate what is causing you not to sleep.
But speaking of sleep, that's where I am going.

I get the flashing folder on booting my MacBook, but only if it is not connected to a power source.

I have an early 2008 white MacBook, running Snow Leopard. A few months ago the hard disk died, and I replaced it. Now when I turn it on (or even wake it from sleep) I get the grey screen with the flashing folder/question mark. However, when it is connected to a power source, this doesn't happen. (this is not dependent on battery as when unplugged, it doesn't start even if the battery is full)
I was hoping for advice on what the problem might be, and how I can sort it to use without being plugged in.
Thanks

Once a Mac becomes 4 years old, the PRAM chip's capacitor or battery is likely to go. This is separate from the battery to affects it on the power lines. Hopefully yours is a battery, since the capacitor is on the logicboard for those that have a capacitor, and are harder to replace.

Could macbook starts without battery by using adapter as power source!!??

Hi all
I have macbook black early 2008 model. My battery is damaged as it falls in water.
I have experienced that If the adapter is plugged with macbook and macbook is on and then i remove the battery ...its remain on...
My question is this that could macbook starts without battery using the power adapter as power source.
Thanks
Regards
Abdul Azeez

Yes it will start and run. The downside is your MacBook will run slower and if you accidentally pull out the plug it will shut off immediately and you'll lose any work that hasn't been saved. I suggest replacing the battery when you can.

MacBook Air USB external drive power source

I have a LaCie 250GB USB external drive on my MacBook Air and the computer is not being able to power the drive without me connecting the hard drive to an external power source. when the drive was had about 80GB of data it would do it, now that the drive has about 180GB of data, it does not work. Can anybody recommend a solution or an external drive that can hold at least 250GB that can be powered by the MacBook Air without need for external power source?

I have the same time of problem. Although, it's mentioned a using a self powered hub. However, I find this did not work. Apple states that the single usb port on the MBA is high powered to give the ext. super drive they sell the power it needs to connect to the MBA. What I have noticed is no matter which USB self powered hub I use I get the same results. The MBA reports that one or more devices is drawing too much power. Although, the powered hub is supposed to provide power to those devices that require power over USB. I should also mention, all I am connecting are two USB devices. 1 ext. Verbatim 500 Gig Drive. and my iPhone. Since the MBA has only 120 gig drive I had to move all of my movies etc. to the Ext. 500 now if I want to sync my phone or move a movie to the phone I get the errors.

Why does my MBP on Mavericks freeze whenever there is a Power Source switch?

As the title suggests, whenever I plug my MBP to a power source or remove the power adapte, the why system freezes for a while (30sec to 1min?).
After the freezing, everything is working again.
Does this thappen to anyone else?
Thanks.

Hi Aerithm,
Thanks for visiting Apple Support Communities.
If you're experiencing unexpected behavior when switching power sources, I'd suggest resetting the SMC first:

I have a MacBook Pro laptop purchased in June 2011, and the superdrive no longer works. Rather than have it replaced, I'll buy a 3rd party superdrive that plugs into the USB port. Does it need it's own power source, or will the USB port suffice?

The Apple external SuperDrive actually exceeds the allowed power draw. Because of this, it is only trouble-free on certain models that accommodate this excess.
All others require an external Power source.

Firmware update was done on my MacBook Air while connected to power source and now I cannot start up. It keeps shutting down. Any ideas??

Start by doing an SMC reset http://support.apple.com/kb/HT3964 and see if that resolves it.

Request quick answer! Will it hurt my Macbook Air to be plugged into a "Uni Pak II" which is a dimming power source?

I'm at a conference and the only plug is a "Uni Pak II" which is a dimming power source (here's the manual).
At first my charging indicator on the end of the MBA plug didn't light, but I slid up the analog slider and it lit up (I knew it had worked yesterday!).
Is there any chance of it harming my MBA or power supply to use this?
Thank you!

Is it difficult to configure Time Capsule in bridge mode
No, it is part of the original setup and configuration, which is guided by AirPort Utility, the application that is used to configure the Time Capsule.
and does it work well with the aforementioned Netgear wireless router?
Works fine since the Netgear will continue to provide the wireless network and serve as the main router on the network
In addition, do Windows PC's backup flawlessly to Time Capsule too?
I cannot speak to that question, since I do not use a PC. I would not expect a PC to work seamlessly with a Time Capsule since the TC was designed to backup Mac computers.
You would have to use a backup application that is designed for use on a Windows computer. Whether or not a given Windows application will work with the Time Capsule and Mac operating system is open to question. You should ask a lot of questions about any Windows application that you might be considering to make sure that it will do what you want.
In that regard, I would suggest that you should probably plan to use a separate hard drive specifically to backup the PC.
