Is removing battery in MacBook Pro 13" advisable?

Can I remove the battery form my MacBook Pro 13" when it is running on AC power? Isn't it charging and discharging decrease battery life? Is battery calibration needed when replacing?

Yes, but you should not. If you do then you no longer have backup power in case of an outage. Your computer will also throttle down to half-power if no battery is present. Lastly, it doesn't do anything to prolong the battery's life.

Swollen battery on macbook pro 17"

swollen battery on macbook pro 17", laptop running hot, can I remove the battery and still use my computer with ac adapter? Also, what is normal temp for laptop?

Yes, you can remove the battery, but if we're talking about a unibody system, you'll need to take it somewhere to have it removed. The batteries are locked in by a rather unique screw. That's because the under side of the battery is soft and can be easily punctured.
But you can have it removed and keep on using it. It will obviously shut off immediately if power is lost, but otherwise there's no issue. And a normal temp is that the system should only feel slightly warm to the touch.

How do I know what files to remove from my Macbook Pro laptop?

Apparently my hard drive is full and I need to remove files so I have space to download more music and movies. I don't want to delete important files. How do I go about doing this?

How do I know what files to remove from my Macbook Pro laptop?
Remove only files you yourself stored on the laptop; files in your Home folder. Don't delete any files from the system libraries, and if you want to remove applications, use the provided uninstallers.
For files in the media libraries - iTunes, iPhoto, iMovie use the application to delete music, photos, movies.
If you are planning on storing more movies and music on your mac, deleting old files will probably not suffice alone to free enough space. Consider to get yourself an external drive to store your media.

After a year of no use and a fully discharged battery, my MacBook Pro refuses to accept the administrator name and the password. How can I reset these?

After a year of no use and a resulting fully discharged battery, the MacBook Pro refuses to recognize the administrator name and password (both). It has system OS X 10.6 which can not be upgraded without the information. How can I reset or reistall the administrator name and password?

Thanks to all who responded. You are all absolutely correct. However, this Ipad was a gift to my wife who was dying of cancer in the hospital and wanted some entertainment. So I started it out with her Apple ID. After she passed away I moved from Sacramento to Austin and eventually proceeded to get the Apple ID changed from my wife's to mine. Meanwhile when she was in the hospital I opened an Itunes account in my name to buy movies for her. That was the first mistake.
Then during the move to Austin I lost track of the IPAD and later found it and tried to use support but could not remember the proper ID. Later the folks at the Apple store helped me create a new and novel Apple ID that was unfortunately unlike any other.
The botom line is that I am stuck with three Apple IDs and three passwords. I am told by Apple there is nothing they can do about this as IDs cannot be changed or destroyed. I can quit using them or start a new account but when I try to do that the system keeps remembering too many things from the past and resists.
Even if I sold this Ipad and bought a new one, the system memory is still there.
I think the real problem is that destop and laptop computers are totally owned by an individual and that individual can control logins and passwords to his liking. IPADs and similar Apple products are different in that the corporation has built in their own intrusion detection schemes because of the relation to Itunes.
One thing I thought about is to open a new Itunes account pretendding to be a new customer with my regular Apple ID. Perhaps I could do the same with Apple Support.
Thanks for your comments.

HT3053 How long should I charged new battery in MacBook pro?

How long should I charged new battery in MacBook pro?

You can leave it plugged in all the time if you wish.
Once your Macbook is fully charged, it stops charging.
You can see this if you click on your apple logo, about this mac, more info, system report, power.
In any event, it is also a good idea to use your Macbook under it's own power to keep the battery in optimal condition.
As much as possible, try not to fully discharge your battery. It could do more harm than good to your Macbook.
Good luck and enjoy your macbook

IMovie was removed from my macbook pro after I downloaded OS X Yosemite, I had it before and have used it, but now I can only get it through the app store

iMovie was removed from my macbook pro after I downloaded OS X Yosemite, I had it before and have used it, but now I can only get it through the app store. I can't pay for it so I would really appreciate the help.

Look in your applications folder for the installer - Install OS X Yosemite. Delete it. Then go back to the App Store purchases tab and see if you can download it. You might have to re-index Spotlight.

Helpful Links Regarding Malware Problems
If you are having an immediate problem with ads popping up see The Safe Mac » Adware Removal Guide and AdwareMedic.
Open Safari, select Preferences from the Safari menu. Click on Extensions icon in the toolbar. Disable all Extensions. If this stops your problem, then re-enable them one by one until the problem returns. Now remove that extension as it is causing the problem.
The following comes from user stevejobsfan0123. I have made minor changes to adapt to this presentation.
Fix Some Browser Pop-ups That Take Over Safari.
Common pop-ups include a message saying the government has seized your computer and you must pay to have it released (often called "Moneypak"), or a phony message saying that your computer has been infected, and you need to call a tech support number (sometimes claiming to be Apple) to get it resolved. First, understand that these pop-ups are not caused by a virus and your computer has not been affected. This "hijack" is limited to your web browser. Also understand that these messages are scams, so do not pay any money, call the listed number, or provide any personal information. This article will outline the solution to dismiss the pop-up.
Quit Safari
Usually, these pop-ups will not go away by either clicking "OK" or "Cancel." Furthermore, several menus in the menu bar may become disabled and show in gray, including the option to quit Safari. You will likely have to force quit Safari. To do this, press Command + option + esc, select Safari, and press Force Quit.
Relaunch Safari
If you relaunch Safari, the page will reopen. To prevent this from happening, hold down the 'Shift' key while opening Safari. This will prevent windows from the last time Safari was running from reopening.
This will not work in all cases. The shift key must be held at the right time, and in some cases, even if done correctly, the window reappears. In these circumstances, after force quitting Safari, turn off Wi-Fi or disconnect Ethernet, depending on how you connect to the Internet. Then relaunch Safari normally. It will try to reload the malicious webpage, but without a connection, it won't be able to. Navigate away from that page by entering a different URL, i.e. www.apple.com, and trying to load it. Now you can reconnect to the Internet, and the page you entered will appear rather than the malicious one.

From user Joe Bailey comes this equally useful advice:
The facts are:
1. There is no anti-malware software that can detect 100% of the malware out there.
2. There is no anti-malware that can detect everything targeting the Mac.
3. The very best way to prevent the most attacks is for you as the user to be aware that
     the most successful malware attacks rely on very sophisticated social engineering
     techniques preying on human avarice, ****, and fear.
4. Internet popups saying the FBI, NSA, Microsoft, your ISP has detected malware on
    your computer is intended to entice you to install their malware thinking it is a
    protection against malware.
5. Some of the anti-malware products on the market are worse than the malware
    from which they purport to protect you.
6. Be cautious where you go on the internet.
7. Only download anything from sites you know are safe.
8. Avoid links you receive in email, always be suspicious even if you get something
    you think is from a friend, but you were not expecting.
9. If there is any question in your mind, then assume it is malware.

How Necessary is PRAM battery on MacBook Pro (c2d intel 2.13, model a1211)

Hello Everyone, I stupidly broke the socket/clip where the pram battery attaches to the logic board on my Macbook Pro (c2d Intel 2.13). Unfortunately, since the socket/clip is a surface mount component and the way it broke (I don't see solder pads) I'm unable to re-solder the clip back on to the motherboard. Here's a picture of what I'm talking about (borrowed from someone else who apparently did the same thing): http://yfrog.com/6ximg0870nj
My first question is if anyone knows how vital the pram battery is to a Intel Macbook? It seems that the laptop works fine without the pram battery. Is the battery only necessary to retain pram settings if the main laptop battery is removed and the power adapter disconnected?
Second question is whether there is any alternative to repair the logic board other than get an entirely new board? The laptop is recently out of warranty (Applecare expired earlier this year) and I don't believe that Apple would have covered this since I caused the damage myself.
Third question(s) is whether it would cause any problems to use the logic board out of a c2d 2.33 a1211 macbook pro (I can get my hands on one for a pretty reasonable price)? The only difference I can see between the two boards is the clock speed of the main processor and the amount of video ram. Would there be any advantage to using this logic board? Doesn't seem like the speed bump and video ram would do to much.
Thanks in advance for any comments/help you can offer.

Much obliged. So it sounds like the only time this will be an issue is if I disconnect the regular battery and the power supply at the same time. The rational thing to do here is to just live with it rather than blowing hundreds on the new logic board and risking additional damage during replacement.
I just wish I wasn't so OCD about this. Bothers me a bit to know that something is wrong with the laptop even if it doesn't manifest itself on a day to day basis.

Using ac power adapter vs. battery on MacBook Pro

I purchased a 15 inch MacBook Pro with retina display a couple months ago. Most of the time I use it with the ac power adapter. Is there any harm to the battery life if I never left the battery drain down some and then recharge it? I have come to understand that when the battery is fully charged and plugged in to an outlet the battery is basically on standby.
Thanks

If you use it mostly on AC, then once every one or two months you should use it on the battery until the battery runs down to about 20%. Then reconnect the AC so the battery can recharge.

Installed New Battery in MacBook Pro--Computer Freezes Twice

Since my MacBook Pro was way past it's warranty, I decided to replace it's depleted battery myself. It wasn't rocket science and it was much cheaper than taking it into Apple and having them fix it for me as I had done so twice in the past (when I was covered under warranty). After I went through the process of removing the depleted battery and replacing it with the new one I got, I ran simple specs on my computer and the battery. The battery is certified new (arrived to me half charged on its first cycle) and matches my MackBook Pro's requirement model and my all of my computer's hardware is functioning as it should. However, since the installation of the new battery, my Mac has froze twice for no apparent reason. The first time it froze was while I was working online (Chrome) with no other applications open. The second time it froze I was running a video via my Mac's storage (file did not exceed 600MB) and nothing else. When it froze the second time, I turned off my Mac and ran the comprehensive hardware check and came up with nothing. I also checked the battery's physical appearance and there's no swelling, leaking, damages to the casing or to the connective wires that run from the battery. So my question is: Could the freezing be due to an undamaged battery that might be a low quality battery, or some other issue?
***My MacBook Pro hasn't had a freezing episode in over a year and it is always kept cool.

**Update**
I had another freeze episode just now from picking up my computer...perhaps something is loose internally. Will be re-checking everything and posting results.

Battery on MacBook Pro drains very fast (even in sleepmode!)

After upgrading to Leopard, my MacBook Pro has become almost unusable as a laptop, since the battery drains very, very fast (I get around half the battery time as before the upgrade).
What's more.. It even drains battery when in sleepmode. When I close the lid or choose "Sleep" from the menu, it now takes several minutes for the machine to enter sleepmode (when the white LED starts pulsating) -- this used to take only 10-15 seconds.
In one incident I had left my MacBook Pro connected to the charger for the entire evening, and the battery was at 100% when I disconnected the charger and put the machine to sleep. I verified that the LED started pulsating and the fans stopped blowing, and went to bed myself. The next morning, the battery level was at 3% when I opened the lid and the "Warning - low battery"-message appeared immediately.
What's going on? ..and now I can't even check for software updates any longer (broken) - http://discussions.apple.com/thread.jspa?threadID=1274099&stqc=true
I have never had issues with my Mac before, but this is starting to near Dell-levels of dissatisfaction!

First, you should remove your serial number form your post. However, since you posted it, I looked it up at https://selfsolve.apple.com.
That's not a valid iPhone serial number. I think you may have a counterfeit device.
Update: There are no legitimate sellers or service providers of iPhones in Oman: https://locate.apple.com/om/en/
You either bought a counterfeit device, or you bought a grey-market import. Either way, you're not going to get service for that device in that country. Since the serial number you provided is invalid, it most likely was a counterfeit. Go get your money back.

Full Battery and MacBook Pro won't turn on

So I was working on my MacBook Pro making a slide show and my other computer needed some power so I unplugged my Pro and plugged it into my other computer. After about five minutes my MacBook Pro just shut down. I don't know what happened, but the power is full and when I press the power button it doesn't do anything. It's almost like the power button doesn't even work. Any help would be very appreciated!! I really need to get this slideshow done!

I recently had a very similar problem... Last Monday I had been using my MBP for a presentation and by the end of the presentation my battery was DEAD. That was ok b/c I wasn't planning on doing anything else that night... The problem came the next day when AFTER CHARGING it would still not turn on. After trying ALL DAY to get my computer to start up, I finally had my mom take it out to the Apple Store and you probably won't like the answer that I got re: my MBP...
They said that there as a lot of dust that had gotten into it (I had had a couple of keys that had come off of my keyboard) They also said that the only way to get it working again was to do a COMPLETE & TOTAL OVERHAUL OF MY COMPUTER at a whopping cost of $1140.00 since a) my AppleCare expired in March and b) they said that there appeared to also be a little bit of OLD water damage!!
     Because I am disabled and the only "work" that I do is volunteer for the non-profit organization that my mom & I founded (Dreams Fulfilled Through Music) I certainly don't have an extra $1140 sitting around to repair this!
     What I finally ended up doing was going to a outside authorized Apple Repair Center where they removed the HD from my MBP (that runs 10.7.4) and put it into an enclosure so that I could still access my data (since my mom has an identical MBP). this only cost me $114 and will allow me to save up for the repairs and or replacement of my computer.
     The problem that I ran into now is that b/c my mom is almost constantly using her computer, I had to try to start up my older MBP with the external HD from my 3yr old MBP. Unfortunately, my older MBP only has 2.16GHz of Processor speed & 2 GB of RAM and unfortunately is only running 10.4.11!! When I plugged in the external HD, I was able to see the drive & it's contents but when I attempted to "Start Up" this laptop from that disk w/ Mac OS X 10.7.4 on it, this laptop wouldn't recognize the new version of Mac OS X and thus wouldn't start up from that disk.
     I've just about decided that I this (now 6 yr old computer) is SIMPLY NOT CAPABLE of starting up from the HD that was taken out of my newer (3 yr old) MBP!!
Does anyone know if this is in fact the case?
I truly hope that this is not the case with your MBP but I figured since our experiences were SO SIMILAR that I should at least share with you what AppleCare Geniuses told me about my computer!
I also hope that someone can also answer my question about starting up my older laptop from the newer HD.
Take Care
