Okay to use MacBook Pro without battery?

Now I fully understand that it is not such a great idea but I wanted to get some opinions: It's my third NuPower battery. All of them have lasted less than a year and failed pretty bad. This one started bulging quite bad and then I couldn't use the trackpad click button anymore (because it was putting pressure on the trackpad / button.) I took it out and the battery started expanding even outside the laptop! I don't consider myself a rough user. I do occasionally reccaliberate the battery per Apple, make sure I raise the laptop off the table etc. to let air pass under. Currently I am overseas and many Apple resellers do not carry the battery in stock. So I have ordered the battery from Amazon. In the mean time, I am using the MacBook Pro directly hooked up to the 240V outlet with the Apple supplied adapter.
I have heard a few people do this in emergencies. But what say you?! Unlike the US 120V, it's 240 Volts here in India! Somehow I felt better with the battery being there to absorb the jolts! but I have had no issues so far - two days. The Mac wakes up, runs, sleeps fine without a hiccup! I am taking extra care not to trip the extra-easy MagSafe adapter
Has anyone done this? Any direct adverse effects caused by running it straight from the outlet without the battery?

Is it okay to use macbook pro in an airplane?

I am new to the mac community and was just wondering if its okay to use my macbook pro in an airplane. I just want to make sure if there is anything i need to know about before taking it on a plane. Thank you.

Air density and pressure (not absolute height) could be an issue if you were climbing Mount Everst.
Airplane passenger cabins are pressurized to the equivalent of a much lower altitude (less than like 2000 meters/6000 feet), so altitude specs do not apply.

How can I install Snow Leopard on my 15" MacBook Pro without using its DVD drive?

I'm assuming your dvd drive is broken? if you have a thumb drive large enough (8GB or better), you can use another computer to make a bootable image from the install dvd to the thumb drive. then you can install from the the thumb drive.

How do I set up my new Macbook Pro without using the annoying Voiceover?

How do I set up my new MacBook Pro without using the annoying Voiceover? I cannot get it to work right; it seems to get stuck and repeats the same thing over and over. It is driving me nuts! Is there a way to begin the setup process without using the Voiceover system? I am a new convert from a PC and I thought a Mac was supposed to be "intuitive!"
Any help is appreciated.
Thanks.
Pamela

There is no good reason to register your Mac anyway.
You can opt out of the setup process and registration by pressing Command (Apple key) and the "Q" key.
The registration process requires you to divulge a lot of unnecessary information.

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.

If you aren't going to live that long maybe you should give up with computers and start enjoying the few remaining hours.

Set up a new macbook pro without using voice over

How do I set up a new MacBook Pro without using Voice Over. I can't get past the initial Welcome screen. The VO commands do not work as indicated in the forced tutorial.

Just click the Next and or Continue button. Voice over only starts shortly after you get to one of those screens and you wait to long to input something or click on an option and then Next or Continue. I think at the bottom of the screen there is an option to turn off the Voice over.

Welcome to Apple Support Communities
iOS apps are different than Mac apps, so you can't use a iOS app on a Mac. You have to purchase that app in the Mac App Store in order to use it with the Mac. They are different operating systems and require different apps

Can you install Windows 8.1 Pro using Parallels on a new MacBook Pro without retina display?

I am starting a graduate school program and I would like to purchase a MacBook Pro. The options for the non-retina display fit my needs best, but it sounds like the resolution requirements for Windows 8.1 Pro do not match the MacBook Pro without retina. I need Windows to run a statistics program (SAS) and ArcGIS for mapping. Any thoughts or experience installing Windows 8.1 Pro on MBP without retina?

The native res on my 13-inch non-Retina is 1280x800. You might check with Parallels support or their forums to see if this is a problem.
If you go with the non-Retina 13-inch, I'd recommend getting 8GB RAM (standard is 4GB) because Win emulators need a fair bit of memory.

I just brought Macbook pro(without retina display) on 15 june 2013 and since then put it on 6-7 hours of charging but still my macbook pro is not 100% charged. but why? (green light is displayed on the adapter pin)

i just brought Macbook pro(without retina display) on 15 june 2013 and when i switched it on the battery was 72 % charged and now the battery is charged to 62%, i used the charger that came with it and kept it for 6-7 hours on charging but it is not charged to 100% but why? also the green light is always on when i plug the charger with my mac book pro.Please tell me the meaning of Green light on power cord lid (mac book pro not charging or charging?) and also the other light if there like amber or any other colour.

Hello Shailendras33,
Congratulations on your new MacBook Pro! Thank you for providing all the information about what is going on with the charging issue.
Firstly, I found some information on page 11 of the MacBook Pro User Guide about what each color of the LED means on the Power Adapter:
When you first connect your power adapter to your MacBook Pro, an indicator light on the
MagSafe connector starts to glow. An amber light indicates the battery is charging. A green light indicates that the battery is fully charged.
You can find the MacBook Pro User Guide here (this is not for the latest MacBook Pro, but the information about the MagSafe adapter is true for the newest model):
MacBook Pro User Guide
http://manuals.info.apple.com/en_US/macbook_pro_15inch_late_2011.pdf
It sounds like you are not getting the amber light indicating your computer is charging, and you are noticing that the battery level is depleting. I recommend resetting your System Management Controller when something like this is occurring:
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Why doesn't the Macbook Pro's battery life last?

Why doesn't the Macbook Pro's battery life last anywhere near 5 hours, as advertised? This is my second one and it lasts 2. It's false advertising, and Apple doesn't seem to making a big deal or know anything about it, which i'm sure they do. Since their general practice is to deny problems exist in all their products, i'm here to make it known that the most recent Macbook Pro has a severe battery issue and it needs to be addressed.
I'm running OS X 10.8.3, Bluetooth is off, and haven't installed any third party software.

My MacBook Pro is over a year old and still gets 2.5 to 5 hours, depending on how intensively my application activity is hitting the CPU and disk. Remember that battery life depends on usage and component loads. You could get 1 hour editing HD video since it would hit all cores and slam the disk constantly, or 8 hours in a cabin in the woods with wifi and Bluetooth turned off, only writing text files, and with the backlight turned down and no disc in the drive. You should check Activity Monitor to make sure you don't have some processes using unusually high amounts of CPU for long periods of time (like browser tabs running Flash ads in the background, chewing up CPU and battery power without even being seen).
Like mende1 says, there are not huge numbers of Mac users getting only 2 hours, or the world would have heard about it by now and MacBook sales would be down. If you are only getting 2 hours there is something going on local to your machine or usage habits.

That's not strictly true. Apple has often announced updates or repair/exchange programs to address various problems that had come up over time. Maybe not always, but it does happen. They also have often helped me and my friends when we brought in Macs that were out of warranty and had problems. They had no legal obligation to work on our Macs for free, but they did anyway.

I'm trying to reinstall Mavericks on used Macbook Pro. When I log in to my Apple ID, it says it was not the same ID used to purchase Mountain Lion. I need to change user/admin as a lot of the folders and apps are in Chinese!

The first thing you should do with a second-hand computer is to erase the internal drive and install a clean copy of OS X. How you do that depends on the model. Look it up on this page to see what version was originally installed.
If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc, which you can get from the Apple Store or a reputable reseller — not from eBay or anything of the kind. If the machine has less than 1 GB of memory, you'll need to add more in order to install 10.6. I suggest you install as much memory as it can take, according to the technical specifications.
If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for some MacBook Air models. If you don't have the media, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To boot from an optical disc or a flash drive, insert it, then reboot and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
If the machine shipped with OS X 10.7 or later, you don't need media. It should boot into Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
Once booted from the disc or in Internet Recovery, launch Disk Utility and select the icon of the internal drive — not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive, which is what you should do.
After partitioning, quit Disk Utility and run the OS X Installer. When the installation is done, the system will automatically reboot into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
You should then run Software Update and install all available system updates from Apple. If you want to upgrade to a major version of OS X newer than 10.6, buy it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the previous owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed — you have to repurchase them.
If the previous owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Apple customer service has sometimes issued redemption codes for these apps to second owners who asked.
If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able toauthorize it under your ID. In that case, contact iTunes Support.

Bought Used macbook pro, don't have administrator password and don't have the OS disc. Is there a way I can reset or delete the password?

I recently bought a used macbook pro. I can pretty much do everything I need on it until I want to change setting and such things. Then it asks me for an administrator password which I do not know or have. On top of that I do not have the OS disc either. Is there a way I can SAFELY reset or delete the password so I can set my own without the possibility of screwing thing up. LIke I said I can do most anything. I figured this out when attempting to tether it to my smartphone for internet access (I do all the time from my desktop but my desktop is a PC so things are a little different) I am a very new mac user, I have always been a devoted PC user until now. I have to say I am really loving my macbook pro I may just stick with mac from now on (if I can get this problem figured out without too much stress.
I am looking for the safest and best way to fix this issue where nothing I do would mess up the laptop. I can use it now and I do not want that to change, I just want to be able to change my setting and set a password of my own. PLEASE HELP, THANX!

Hi
There actually is a slightly easier way in OS X 10.5 or greater.
1. Start up in single-user mode (hold Command-S as the computer starts up).
2. Type: mount -uw /
3. Press Return.
4. Type this:
passwd (user's short name)
Replace "(user's short name)" with the short name of the user account whose password you wish to reset. If you are not sure what the account name is, you can get a list of user names by typing: ls /Users
5. Press Return.
6. Enter a new user password.
7. Press Return.
8. Type: reboot
9. Press Return.
