Macbook Pro : Battery Hit From USB Keyboard

I'm going to be using my Macbook Pro to do some live music sets, and I'm wondering how big the battery hit will be from a controller keyboard (i.e. a musical keyboard) powered via the laptop's USB port. Just a rough idea - will it double the battery usage, add 25% etc...?
The thing is, some of the performance locations will have no electricity supply, and basically I'm trying to work out whether I need a controller keyboard with its own internal battery compartment.

As you are aware, batteries (no matter what manufacturer) are consumable devices and is only covered for one year (barring any type of abuse). With your purchase date being in 2007, this would not be covered under your AppleCare extended service plan.
Suggest you make an appointment for your local Apple Genius Bar and they can perform a Battery & Adapter test. You can always start the process by contacting AppleCare (1.800.APL.CARE) and log down your case number after you have completed your discussions with them, so when you get to the Genius Bar, it will save you time. At that point they will be able to determine if the battery is defective and commence the replacement process. Include your case number in the notes section of your Genius Bar appointment form. This tests will check your MagSafe adapter and battery at the same time and takes about a couple of minutes if that. Hope this helps guide you through the process.
Cheers,
Pete

Macbook Pro battery goes from 100% to 93%?

Upon charging my MacBook Pro 13", it fully charges to 100% but not even a minute later, suddenly drops to 93% and then resumes depleting normally.
Anyone know of anything happening like this before? I recently just got my battery replaced so nothing should be wrong with it.

Have you calibrated the battery?

I plugged in my ipod and now i get the error message: Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled" - i have a MAcBook pro and now my USB ports do not work - can anyone help me ???

Sometimes you have to reset the SMC two or three times for it to work, don't know why. I've seen that error message before and 100% of the time it was fixed with an SMC reset. I suppose it's possible that your keyboard or mouse IS drawing too much power, do you have access to another you could try?

You will need to install an App like Print Central on the iPad to try to print to the printer. It will allow you to print to most printers. Check with their support folks if you need more info.

I wish to upgrade my Macbook Pro to ML from SL but told the only way to do this is by downloading thru App store. Is it possible to copy ML on a USB and upgrade that way. I would like to have a back up of the OS just in case i have a problem later. Help!

You can create an install disc but you would have to download Mountain Lion to do so..

Brand new 15" MacBook Pro Retina - unplugged from Thunderbolt Display and Keyboards today find keyboard alpha-numerics not working; except the function keys, delete key, tab key, command/ctrl/shift/alt/fn and arrow keys; and 7/8/9/u/o/j/l nudge cursor

Brand new 15" MacBook Pro Retina - unplugged from Thunderbolt Display and Keyboards today find keyboard alpha-numerics not working; except the function keys, delete key, tab key, command/ctrl/shift/alt/fn and arrow keys; and 7/8/9/u/o/j/l produce cursor nudges.

It's a new machine - and the Thunderbolt Display is meant to work with it. You need to just make an appointment at your local Apple Store and have them fix whatever is wrong.
If you like, you could always try a SMC reset and a PRAM/NVRAM reset to see if either of those will get your keyboard back in working order...

My MacBook Pro Core Duo from 2006 shuts down randomly requiring frequent reboots to the point I had to abandon doing any project or anything on this MacBook Pro. Same thing occurs with the iMac dual core from 2007. MacBook battery replaced.

My MacBook Pro Core Duo from 2006 shuts down randomly requiring frequent reboots to the point I had to abandon doing any project or anything on this MacBook Pro. Same thing occurs with the iMac dual core from 2007. MacBook battery replaced. Is it internal battery for both, new logic board required, bad hard drive, or bad RAM?
Help.

Run an Apple Hardware Test using the original installation disk that has the AHT instructions on it.
Try SMC and PRAM resets:

It is possible that you may need a new PRAM battery.

My 1 week old macbook pro battery is dying.

my 1 week old macbook pro battery is dying. i charged it to 100% then went to bed and this morning it is at 32% when turned on. What the heck?

my light does not flash in sleep mode.
Which means it isn't sleeping. Run the Console and put the computer sleep. Experiement with the sleep command and closing the lid. Does it sleep with the sleep command but not the lid? Does it not sleep in either case. In the Console, by default, you'll see all the messages that are logged. Pay attention to when you close the lid or execute the sleep command and pay attention to the log entries that occur at that time and shortly afterwards. You might find a sleep terminated type message which will give you a clue about why it isn't sleeping.
There are also programs that are known to cause insomnia. At the head of my list are all it one printer software because the drivers often constantly look for an incoming fax or the keypress from the AIO printer console.
One more thing - if you have been putting it to sleep and then disconnecting USB or FireWire devices - that's the problem.

How do I use a NORMAL headset (dual 3.5mm) on my new Macbook pro retina? No usb ports available and headset buddy adapter doesn't work.

Hi Auracles1,
Here's a pretty discussion regarding wireless printing with this device and a Mac.
http://h30434.www3.hp.com/t5/Printer-networking-and-wireless/HP-Officejet-6500-E 709n-wireless-issue/m-p/258853
I have a similar OfficeJet and it was a multi-step process. (1) Install printer drivers on the machine, (2) Add the printer queue in print & fax, (3) Run the "setup wizard" from the disc for wireless printing.

MacBook Pro 13" Early 2011 Backlight Keyboard Not Working?! Software Problem...

So my "MacBook Pro 13" Early 2011" backlight keyboard hasn't been working. I have tried LabTick today, doesn't fix anything. Even in high or low lighting situations (dispite the Adjust keyboard brightness in low light being off) doesn't like to go on. It doesn't give me a circle with a cross like it does with that box checked in day light. It shows on the screen the
16 dots fully light after hitting F6 fully, just it doesn't light up. I one time had to reset my Mac OS at the Apple Store, it fixed the problem, but when I restored with a time machine backup, it went back to this software problem. How can I fix this?! What is wrong with my OS? Mountain Lion? How can I fix this?!

If it does not detect the display automatically, try going to system preferences>displays, click detect displays.

Pretty nice change for those C2D's

I have a Macbook Pro Early 2011 from the USA. After installing Mavericks, Adobe CS6 crashes whenever it is plugged into a 27inch cinema display I purchased from the apple store in China (We moved to China). It works when not plugged into 27inch display.

I have a Macbook Pro Early 2011 from the USA. It is now running Mavericks. I connect it to a 27" Cinema Display that I bought in China after we moved to China. Before I installed Mavericks, I could run all of the Adobe CS6 and Adobe CS5.5 applications on my Macbook Pro while connected to the cinema display. Now that I have Mavericks installed, whenever I am connected to my 27" CInema display my Adobe applications crash upon opening. I know this is a rare scenario, but does anyone have any ideas how to fix this problem? Is there a new driver that needs installed? I'd appreciate any help.

I am also having a similar issue. I used Adobe Lightroom and my whole display goes black. Even my laptop screen and the lights on the keyboard go black. I can still hear the fan running, so I assume it is just the display. This is my first Mac and I have had nothing but issues. I think I am going back to Windows after this.

Hi I seemed to have picked something on my MacBook Pro that hits me with a survey that involves winning a new iPhone 5 or iPad. Is there anything you can advise to get rid of whatever it is?

I did download clamXav software as someone on line recommended it which duly scanned my computer and located some infected files. However, I don't know how to select these files to delete them. Does anyone know an idiot's guide for this software?

Format Macbook Pro Hard Drive without a keyboard

HI, I have a macbook pro with a water damaged keyboard that I am selling for parts. I need to know if there is anyway to delete all of content and or format the HD without the use of an apple keyboard. I have a cheap external keyboard i am using that does not have the apple command and options key. Anyone have any ideas?

You could simply remove the hard drive.
Weather you choose to reformate it in an external enclosure would be up to you, if you think for parts it should be included.
You can buy a Apple bluetooth keyboard from Best buy and see if you can get it to connect, either way you have 15 days to return it.
