My macbook pro has service battery, what could happen if i upgrade the ram to 8gb

"Service Battery" means just that - you need to make an appointment with your local Apple Store or AASP and have the battery checked out and, likely, replaced.
If you upgrade to 8GB it will have no effect on the battery. 8GB is sort of the minimum that I would shoot for.

Welcome to Apple Support Communities
Of course. Corsair RAM is compatible with your Mac and the Early 2011 MacBook Pro supports 16 GB of memory. Make sure you buy the correct memory for your MacBook Pro. See > http://www.corsair.com/us/memory-by-product-family/mac-memory-upgrades.html

I have a 15' Macbook Pro, mid 2010 running Mavericks. I want to upgrade the hardware by increasing the RAM to 8GB and replacing the HD for a SDD one. What would be the best way to install mavericks on the new HD? I have the original OS X CD.

I have a 15' Macbook Pro, mid 2010 running Mavericks. I want to upgrade the hardware by increasing the RAM to 8GB and replacing the HD for a SDD one. What would be the best way to install mavericks on the new HD? I have the original OS X CD.
From what I read, I have 2 choices: 1. to install OSX and then upgrade to Mavericks, but I'm not sure if this would be possible (to upgrade directly from OSX to Mavericks); and 2. to use a software called Super Duper.
I wouldn't like to have to use a third party software to do this, so the question is: is there a better way to install directly the Mavericks not having to use a third party software?

Install the new drive in the computer.
Install the old drive in an external USB or Firewire enclosure.
Boot the computer from the Recovery HD on the external drive.
Use Disk Utility to partition and format the new internal drive.
Clone your external drive to the internal drive.
How to replace or upgrade a drive in a laptop
Step One: Repair the Hard Drive and Permissions
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger, Leopard or Snow Leopard.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Step Two: Remove the old drive and install the new drive. Place the old drive in an external USB enclosure. You can buy one at OWC who is also a good vendor for drives.
Step Three: Boot from the Recovery HD on the external drive. Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the Recovery HD then click on the downward pointing arrow button.
Step Four: New Hard Drive Preparation
1. Open Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your new hard drive (this is the entry with the
      mfgr.'s ID and size) from the left side list. Note the SMART status of
      the drive in DU's status area. If it does not say "Verified" then the drive
      is failing or has failed and will need replacing. Otherwise, click on the
      Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from
      the drop down menu to one. Set the format type to Mac OS Extended
      (Journaled.) Click on the Options button, set the partition scheme to
      GUID then click on the OK button. Click on the Partition button and
      wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the
      drive entry) from the left side list. Click on the Erase tab in the DU main
      window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the
      Options button, check the button for Zero Data and click on OK to
      return to the Erase window.
6. Click on the Erase button. The format process can take up to several
      hours depending upon the drive size.
Step Five: Clone the old drive to the new drive
1. Using Disk Utility still opened.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
5. Select the destination volume from the left side list and drag it to the
      Destination entry field.
6. Select the source volume from the left side list and drag it to the
      Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new internal drive. Source means the old external drive.
Step Six: Open the Startup Disk preferences and select the new internal volume. Click on the Restart button. You should boot from the new drive. Eject the external drive and disconnect it from the computer.

Late 2013 macbook pro showing Service Battery warning after 1 year and 2 months

Hey there,
I purchased a 13" MacBook pro retina late 2013 in December
The battery has recently started showing the "service battery" warning. Here is a screenshot from Coconut Battery:
Surely after only about a year the battery should not be holding only 70% of the charge. Is this level of wear unusual? If I were to take this to an apple store would Apple likely replace it even though it is out of warranty?
Cheers guys.

unfortunately, the batteries warranty is only one year. The only options were the ones they gave you: buy a new battery (which I recommend), or use your mac on the power supply only without the battery.

Pls help. MacBook Pro is dead. What could be the problem?

My macbook pro just suddenly won't turn on, won't charge and will not let me do anything on it. I bought it Sept 2010 and I never had any problems since.
When i plug the charger there is an orange light blinking, you wont even notice it so much. The battery life indicator on the side is not working too.
Here are the things I tried with another macbook pro:
Changed charger (my charger is working)
Changed the battery (my battery is fine) and put it back.
I saw online instructions but it seems my Mac still is totally DEAD:
1. Holding down power button for 10secs
2. Reset SMC http://support.apple.com/kb/ht3964
3. And Safe Boot and Fsck etc.. http://www.macworld.com/article/2018853/when-good-macs-go-bad-steps-to-take-when -your-mac-wont-start-up.html
I'm hesitating to try the dvd cause it might just get stuck inside since my Mac doesnt really respond to any.
And I could just go to the Apple Store and save time and effort but it's not that easy where I live in and I would like to have my Mac's life back asap.
Any help is appreciated!

Zap the PRAM.

Macbook Pro has short battery life and runs hotter after firmware update

I installed the macbook pro EFI firmware update yesterday and now my MBP runs hotter and the fan starts running earlier than it has ever done before. Also, my battery lasts 51 minutes from a full charge whereas, before the update, it lasted 2 hours (using the same programs and display settings).
Has anybody else seen this problem?
Please tell me I'm not alone with seeing this. I am hoping that there is a solution and it's better than 'buy a new battery'. The fact that my box now runs hotter with the fan on more constantly would not be solved by a new battery I think.

Also had the problem of MBP running much hotter after most recent Firmware update.
My fans have been running at 6k RPM constantly, and processor Temps have been running at 70-88°.
Following the advice in this topic, I checked the Activity Monitor, which told me both my account and my son's account (which was running but had no actual applications running) had separate Airport processes going nuts – each at approx 80-95%!
Switching off airport and logging out of my son's account almost immediately started to cool the processors, and the fans began to slow down. Switching Airport back on doesn't seem to heat things up again, but if I start to crunch numbers, it all happens over again...
So who knows why the firmware update is making these processes freak out.... weird.

Macbook pro showing Service Battery

Suddenly my macbook pro is showing Service Battery. how do i fix it?

Bring it to an Apple store or AASP.

It doesn't seem like my new macbook pro has a battery

I got my new MacBook Pro 13-inch LED-backit widescreen notebook about a week ago. The first time i tried it, I plugged the Power Adapter in the whole time i used it. The next morning i tried using it, but this time i didn't have it plugged in. It wouldn't turn on. So, i plugged it in and then it worked fine. I searched for the problem and then i noticed that on the top right corner, the battery sign had an X on it. I clicked it and it said "No Batteries Available | Power Source: Power Adapter". i did a little experiment. i plugged off the Power Adapter during the middle of me using it and it completely shut down. I figured that it didn't come with a battery when i bought it. Is this normal and do i have to buy the battery seperately?

Absolutely not normal - check one more thing:
Go to the Apple in the menu bar and click on About this Mac, then on more info. Click on System Report. In the resulting window, click on Power and see what is listed there (hopefully the battery) - post the results here. If there is something wrong with the battery, call Apple - you have 90 day phone support (and a year hardware warranty) and/or book an appointment at your nearest Genius Bar.
FWIW, the new laptops have batteries built in (not accessible by user).

If there is no improvement, consider installing a new battery.
Ciao.

My macbook pro is not charging, what could cause this problem?, my macbook pro is not charging, what could cause this problem?

I am so worried because my laptop is a month old I cant be having battery problems FML

If your computer is only a month old, you're still under warranty. Take it into your local Apple Store or an AASP and have them run diagnostics. You could have a bad battery, a hincky power supply, who knows? It's rather difficult to diagnose these things over the Internet - take it in and let the professionals handle the problem.

New MacBook Pro has a few very small blue straight lines on the display...

but only on the desktop (Finder). Right now, there are only about 3 of them, but very annoying. They are less than an 1/8th inch long.They are in different areas of the display-two of them are vertical, the other horizantal. No matter if I use a photograph, or a solid background color, the lines are still visible. But open applications do not show the lines. That is wierd. These lines started only 3 days ago. They went away for a brief time, then came back today. Any suggestions or solutions?

Take it back since it's new and in warranty.

My Macbook Pro has Maverick OS, but it was wiped clean at the Genius Bar. Now I do not have Bon Jour and I can't reinstall my Epson XP 410 printer without Bon Jour?

Can't get my printer to appear on the Add Printer List - it is greyed out. Says to use Bon Jour, but it was deleted. Lost all my apps when Genius Bar wiped my Mac, but now they say they do not deal with third party apps.
Can I download Bon Jour somewhere?
Thanks for any help you can give.

Thanks.. I had Bon Jour on the Maverick that they wiped out, and it was in my Sidebar. Now I can't find it on the new install. I have looked in Applications, Utilities and in the System. When I Search, it is not found. I have the printer drivers for my Epson 410 installed, but it asks that Bon Jour be used to find and add the printer. It is very frustrating. I will go back to my last update on Passport and see if I can find it. As I am sure you can tell, I am not very experienced with this. But I appreciate your response!

HT1338 I have an older macbook pro running OSX 10.6.8. Should I upgrade the OS?

SHOULD I UPGRADE FROM 10.6.8?

10.7 or above will not run your PPC based programs, so that's a cost.
10.7 or above will need 4GB or more RAM, so that's a cost.
10.7 or above is slower than 10.6, so that's a cost in performance
If your machine is out of AppleCare, then if 10.7/10.8 hoses your machine somehow (like it did mine), then your screwed and have to buy a new one.
If the machine originally came with 10.4 or 10.5, then you certainly don't want to upgrade past 10.6.8 and slow it down, just run it until the wheels fall off.
I only advise Early 2011 machines and later to upgrade to 10.8, then only under AppleCare.
Apple is issuing security updates for 10.6, installed anti-virus, and it has about 30% version market share, so your safe for now.
