MacBook Pro Mid 2010 Battery Capacity

I've read a few threads about this, mostly about battery capacity rapidly dropping after an install of ML. I installed ML when it first came out, and just noticed the drastic decrease in battery life about 3 weeks ago. My capacity could have potentially been dropping since I installed ML (and I just now noticed it), or it may have just started a couple weeks ago when I noticed. I'm not sure.
Either way, my MacBook Pro (Mid 2010) now has a battery life of less than an hour, even with extremely light processor load. I contacted Apple about this, and the tech said that the battery was rated for 1000 cycles. I'm currently at 220, and my battery capacity is a pathetic 30%. He said that since I wasn't under warranty, there was nothing they could do besides replace the battery - which I really want to avoid since I'm a broke college student.
Is there anything I can do here? I understand that I'm not under warranty anymore, and this wouldn't be a problem if my battery was degrading normally. However, getting 1/5th of the recommended battery life is pretty sad. I've read that doing a clean install of Mountain Lion/Lion might help. Is there a way I can do this without having to back up all my files? I don't have an external hard drive or anything.
It seems this is a common topic in these forums. Any help or links to solutions would be great. If this is answered in a similar topic, I'll gladly delete.
Here is the system info on my battery, incase that might help:

What are the best practices to extend the overall lifespan of my MacBook Pro and its battery?

In general what are the recomended practices to extend the lifespan of my batter and other general practice to extend the lifespan and characteristics(such as performance and speed) like new on my MacBook Pro which this past fall (2011)?

Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible. Drive Genius provides additional tools not found in Disk Warrior. Versions 1.5.1 and later are Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
SyncTwoFolders
Synk Pro
Synk Standard
Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac Maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.

2 day old MacBook Pro at 98% battery capacity

I'm a little bit concerned about the lifespan of my new MacBook Pro's battery. When i recieved the machine i performed a battery calibration as Apple recommends. I then charged and discharged again. I was concerned when Coconut battery (not always accurate) told me my battery was at 98% total capacity. Is this normal? after 2 cycles my capacity is down 2% .
I'm surprised because I've never seen this on my old iBook which usually loses 1% capacity per month.
I've read that these lithium ion batteries have a memory, that the cells not being used stop functioning because they are not needed. Is this true?
When at home should i keep the machine plugged in? My iBook used to be fine when i took it to school and drained it, then charged it at night. Opinions?

More or less, yes, I do. Actually turns 5-days old today and at 97.8% of capacity (5330 mAh compared to 5450 when new) after 4 battery loadcycles. Coconutbattery says this is 97%, but my math is a bit higher at 97.8%. Clearly this rate of decline is not sustainable.
So my question to you was, did "don't worry, enjoy" mean that in your experience, the initial few percentage points of battery capacity is blown off quickly, but the battery capacity will quickly stabilize to something that is still acceptable?
My battery on a full charge this morning (day 5 of ownership) lasted 3:50, with display at 50%, no use of the optical drive, Wifi on, bluetooth off, and running Mail, Safari, Firefox, iCal, Excel & Activity Monitor (to keep an eye on things). No work was done in Excel, Firefox or iCal, just Mail & Safari. So, I, too, am a bit concerned about being nowhere near 7 hours. Or 5 hours, for that matter. So, short battery life and losing 2.2% of capacity in 4 loadcycles and 5 days is concerning, and tempting to connect the dots.

Macbook pro looses login settings with thunderbolt display

I've noticed that on occasion my MacBook Pro looses its desktop settings when connected to a Thunderbolt display. Why Thunderbolt display discards my MacBook Pro window environment settings upon boot-up is unknown to me. I can tell when this happens when my desktop loads different backgrounds from those on my MacBook Pro. Furthermore, the option in the System Preferences for changing my desktop background will cease to function. I even notice system wide speed degradation.
In order to correct this and reload my MacBook Pro settings I must identify a specific file named “com.apple.loginwindow.plist” and delete it. Doing so resolves whatever existing conflict so that Thunderbolt displays the correct background and enables System Preferrences to work properly.
I would appreciate very much if anyone has a resolution for this problem.
Respectfully,
TomBoltz

I think you need to do a search of the of these forums to see if there is an answer. I saw a lot of suggestions, but the #1 solution is buying a brand new cable. I have personal experience with that. My son recently switched from an HP to a MacBook Pro. The HDMI cable worked perfectly with the HP. It didn't with the Mac. He got a new cable for the Mac, everything resolved itself.
I have heard all kinds of speculation on it, but it happens frequently enough that there must be something going on. I'd spend $30 on a new MiniDisplayPort to DVI connector or whatever you use.

Macbook pro late 2010 battery at 24 cycles for 15 weeks computer and capacity is already 93%, anything wrong?

macbook pro late 2010 battery at 24 cycles for 15 weeks computer and capacity is already 93%, anything wrong?

How many cycles depends on how often you drain the battery down low and then recharge it to maximum, ideally use it a little less on battery and a bit more on mains and the cycle count will slow down. Every couple of months you need to re-calibrate the Battery for best long term results.

Why did my 17"Mac Book Pro loose its ability to output video through it's adaptors?

Why did my 17"Mac Book Pro loose its ability to output video through it's adaptors? I have S-Video, RC, and an HDMI adaptors that use to work and output video. At somepoint an OS upgrade stoped their functionality. Is this something I can correct? If so, any ideas as to a path to follow?

2011 and later MacBook Pros shifted to Thunderbolt.
Pre 2010 MacBook Pros may have a PRAM battery getting old.
One of these factors may exist. Not knowing the age of your MacBook Pro, I can't say for certain.

Does the system still run off the battery only? Does it run for a few hours off the battery only? Then No it is not defective and no Apple will do nothing for you and No Applecare does not cover Consumable items which the battery is one of those.
The only time Apple MAY, and that is BIG MAY, replace the battery is within the first year and only if Apple Deems the battery to be defective. Fat chance of that as long as the system runs off the battery for any length of time.

Macbook pro mid 2011 battery lasting only 3 hours

How can I get my brand new Macbook pro mid 2011 battery to last longer, now it's lasting only 3 hours.

Do not believe the advertised specs from any manufacturer regarding battery life. In the real world expect about 60% to 70% of those figures. Battery life is influenced by many factors, Among these are display brightness, the number and type of applications you are running, if the optical drive is used, external devices that may be attached etc.
3 hours seems a bit low but not necessarily out of line. Go to SYSTEM PROFILER>POWER and see what it says by 'Condition'. If it is other than 'normal' you may have battery issues (Explanations then can be found in FINDER>HELP).
Ciao.

I downloaded and bought a movie from iTunes on my iPad and now want the same movie on my MacBook Pro but its not offering me to download it, it giving me the options of buying it which I already did. How I get the movie onto my MacBook?

I downloaded and bought a movie from iTunes on my iPad and now want the same movie on my MacBook Pro but its not offering me to download it, it giving me the options of buying it which I already did. How I get the movie onto my MacBook?

You can connect the iPad to your Mac's iTunes and do File > Devices > Transfer Purchases, that should copy it over to the Movies part of your library.
Depending upon what country that you are in, and whether the film studio allows it, you might also be able to re-download it on your Mac via the Purchased link under Quicklinks on the right-hand side of the iTunes store home page.

HT201376 Hello, I am trying to reset my macbook pro to its factory settings but I can't type the name of the formatted disk nor can I click on erase, as this feature is disabled. Could you please assist?

Hello!
Did you boot to the Internet Recovery Partition?
Here’s how:
1/ Make sure your computer is completely shut down.
2/ You’ll have to be quick next: Press the Mac’s power button. As soon as you either hear the loud chime, or see the display light up - usually after a second or 2 - on your keyboard press [alt] + [cmd] + [r] Keep these keys on your keyboard pressed until you see a spinning globe with the text “starting Internet Recovery” You might have to connect to your Wi-Fi network before you can continue here.
After a few minutes, you’ll be presented with a Utilities screen. This is the Internet Recovery partition. If this step is already giving you problems, try using a USB-keyboard. It doesn’t have to be an Apple-keyboard. If you have a Windows-tailored keyboard laying around, use the “Windows-flag” key in stead of the [cmd]-key and it should also work.
3/ Choose Disk Utility and click [continue]

Imported old computer via time machine into new 2012 macbook pro, but its still running ilife 09 instead of 11?

imported old computer via time machine into new 2012 macbook pro, but its still running ilife 09 instead of 11?

I am assuming you had iLife 09 on the old computer - when you moved everything over, that came along with it.
I also have older versions of iLife (on install disks) and just recently got a new 2012 Macbook Pro. I noticed that iMovie 11, iPhoto and Garageband (I think) are listed in my Mac App Store Purchases with a notation to "accept". So you might want to check MAS to see if the apps are sitting there.
Now, I have chosen not to accept them for now for two reasons: I have iLife 11 on a disk and prefer that rather than having it tied to MAS/Apple ID and as long as I have my disk version installed, I also still have iDVD which I use a lot. I'm not sure if "accepting" those three from MAS would wipe out my iLife 11 installs including iDVD (which would be unacceptable for me). So, since I already have the latest version, I've opted to ignore the "accept" and, in fact, will leave it like that - if I ever sell this machine, the buyer can then accept them if they want with their own Apple ID. So before accepting the apps (if they are listed in MAS), you might want to check to make sure that your iLife install isn't wiped out - that is, if you have iDVD and want to keep it.

2011 MacBook Pro loose trackpad

About a few weeks ago my three-month-old MacBook Pro's trackpad started making very noticable annoying "click" sound (especially on the right side), as if something was loose underneath. I went to my local Apple store, and the genius "tightened up the screws and cleaned out the debris". He said he didn't notice any difference, however the problem persists when I tested it. He offered to replace the trackpad for me free of charge (as my Mac is still in warranty), and the problem seemed to have gone away. However when I got home, the problem arose again, this time on the left side of the trackpad. It is a tiny "click" sound when putting very little amount of pressure on the trackpad (I did not press it down fully). It is not easily noticable, but very annoying indeed. Im probably going to visit them next week again to get the things right. Anyone having the same problem??

The trackpad will "click"when pressed as a feedback that the user have clicked (same as left mouse key) on something.
The "click" occours at very low pressure when pressing left, right, center or downside the pad.
For that i assume, your trackpad work as designed.

Hold Option key when starting - that gives you the option to choose between startup disks.
