My Macbook Pro loses power with battery down to 85%

I have had this problem for about two weeks. My Macbook Pro runs fine when attached to the power adapter, but when it is on battery power, no matter what applications I am running, the computer suddenly turns off after about 10 minutes when the battery reads about 85% charge. It will not restart until it is reattached to the power adapter. The computer is from about 2006 and has the original battery.
I ran diagnostics and it says the battery is working okay. I ran the utilities application to see how much CPU was in use, and it was only about 5% for all CPU capacity, and none of the running applications seemed to be using much of the hard disc.
I am planning to go to the Apple Store, I suspect they will tell me I need a new battery. Can it be tested at the Apple store out of the computer? Can I test it at home with my home voltmeter?

This is a sign of a battery that has reached the end of its life and needs to be replaced. Getting nearly nine years of use from a consumer rechargeable battery is a small miracle, congrats!

Macbook Pro - no power with AC adapter or battery

I recently had the logic board replaced due to the NVidia issue on my Macbook Pro. It was working great when I got it back, except that the battery was jammed because the tech put the RAM cover on slightly wrong. I tried to get the battery out - pried a bit but nothing crazy. Then took it back to the tech to remove the battery and he pried it out gently. Now the computer won't start - just dead. With or without battery and I have tried resetting the power controller. No luck...
Any help would be greatly appreciated. There is absolutely no visible damage to the computer from the stuck battery.

Sending it off to Apple is likely your best option. I'm not sure I would have much trust in a tech who put the RAM cover on wrong.
I think you probably have a damaged Left I/O Board, which is what contains the power port. The board may have been damaged when the logic board was replaced.
Do send it off--I think it is beyond the ability of your local tech.
Good Luck!

MacBook Pro shutting off with battery charged

I have a MacBook Pro I purchased about 22 months ago. About seven days ago, I started noticing the computer just shutting off without warning, even with a charge of 20% or more. Using Coconutbattery my batter still has 62% of it's original capacity with 367 load-cycles. Battery life isn't great, so I was considering buying a new battery, I'd just like to know if other's experience this, and would a new battery solve the problem.
There are no other problems with the machine.

MacBook Pro loses connection with Bluetooth Headphones

Hi,
Every time I turn off my bluetooth headphones and then turn them back on, my mid-2009 MBP loses connection with them and forces me to re-pair them. It comes up with an error where the only option is "Stop using headphones" - does anyone know a solution to this?
My headphone are Sony DR-BT101.

Same problem here... With Mac OS Lion. Any solution to this?

Using my macbook pro whole day with the power adapter , will it affect my battery? Please help

Using my macbook pro whole day with the power adapter , will it affect my battery? Please help

It doesn't affect the battery. You can use your MacBook Pro plugged in all the time without damaging the battery. You only have to be sure that you unplug it and run a battery cycle (drain the battery without letting the Mac turn off and charge it fully) at least once a month to keep the battery life.

HT201257 Hi -- I have a late 2011 13" macbook pro that shipped with and runs Lion. Unfortunately, I do not have the install disks with me. Holding down D key does nothing. What can I do?

How can I run the hardware test on a macbook pro that SHIPPED with lion (never had an earlier OS) without access to the install disks? I am away from them and home for several months. Holding down the D key does nothing.

Press "Option" and "D" key together.
"Restart your computer, holding down the “D” key while the computer restarts.After your computer restarts, you should see the Apple Hardware Test chooser screen. If you don’t, Apple Hardware Test may not be available on your computer. You may be able to start Apple Hardware Test from the Internet. Reconnect your computer to the network, and then restart your computer while holding down both the Option and “D” keys."

I plugged in iPhone 5 charger to my MacBook Pro and it immediately shut down and I can't get it restarted. Any ideas how to do this without removing the battery?

If you have your MBP charger, try a SMC reset:

HT3053 Can I run my MacBook Pro Late 2008 without battery forever? Is it bad in long term or anything? Does it make the system less stable?

Can I run my MacBook Pro Late 2008 without battery forever? Is it bad in long term or anything? Does it make the system less stable?
My battery got swollen (and I unfortunately noticed it very late and might have be running with it for months, which potentially explains all the crashes everyday and the trackpad not working anymore, the Apple test also says I have a bar of ram broken...) and I had to remove it because the back pannel did not close anymore... Can I still use my MBP normally forever that way? I was planning on buying a new mac anyway but maybe waiting for the next iMac upgrade in the year... Should I wait?

Other than the system shutting down instantly if you have a power outage, whcih could corrupt the OS. Nothing else bad will happen.

My MacBook Pro's power source is draining my RAM.

I've got a MacBook Pro (mid 2010) with 8gb of RAM (just installed new/more RAM last week). For some reason, my power supply seems to be draining my memory. When my machine is connected to its power source, my RAM dwindles down to 10mb. If I remove the power cord, the memory goes back up into the 3gb to 4gb range. Anyone know why this is happening and how to remediate this issue? Thanks in advance.

Don't "calibrate" the battery, that's a waste of time.
While the problem exists, launch Activity Monitor according to the following:
Using Activity Monitor to read System Memory and determine how much RAM is being used (OS X Mountain Lion and earlier)
Make the window large enough to capture as much as possible.
In the View menu, select Active Processes.
In the View > Columns menu, de-select User and make sure that Memory is selected.
Select the Memory tab, and click the Memory column so that the triangle is pointed "down", sorting that column in decreasing order.
What you see should resemble the following:
Post a screenshot (see below) of the Activity Monitor window.
To take a screenshot hold ⌘ Shift 4 to create a selection crosshair. Click and hold while you drag the crosshair over the area you wish to capture and then release the mouse or trackpad. You will hear a "camera shutter" sound. This will deposit a screenshot named "Screen Shot...." followed by a date and time on your Desktop.
When you post your response, click the "camera" icon above the text field:
This will display a dialog box which enables you to choose the screenshot file (remember it's on your Desktop) and click the Insert Image button.
⌘ Shift 4 and then pressing the space bar captures the frontmost window.
⌘ Shift 3 captures the entire screen.
Don't capture or upload any information you consider personal.
Drag the screenshot to the Trash after you post your reply.

HT1237 macbook pro turns off with no warning...

my macbook pro (late 2011) is powering down without warning. I'll be writing an email and w/o warning, it's off. I'm unable to turn it back on with the power button unless i hold it down for a slow count to 10. Fyi - machine is 100% charged when this happens. Two days ago, I did SMC and PRC resets with Apple Care. I needed to do both of these again yesterday on my own. Can anyone tell me what's going on - do I need a new battery? Thanks

Some MacBook Pro versions cannot be upgraded past 10.6.8; others are maxed out at 10.7.5. newer models can go all the way to 10.10. So it is important to know exactly what version you have--there may be close to 40 variants produced since the MB made its debut in 2006.

I just upgraded to Maverick on my2 year old Macbook Pro and it has slowed down the computer terribly. All I see is that whirling circle every time I do anything. How do I go back to old OS. Terrible upgrade -- forces you to buy a new Mac!!!!

It does not. First things first have you tried restarting?
Try restting PRAM

Also open "activity monitor" and look and see what is using a lot of processing power.

The battery for my macbook pro 13 says "service battery". Now I want to get a replacement but the reviews for it are horrible! Does anybody have any suggestions? I don't want to spend 130 dollars on something I'm going to have to replace in less than a year (which is what normally I been reading) I do design work and I take my mac everywhere. Having to always look for a plug or having to be constantly plugged in doesn't sound ideal to me. Please help me. what should I do???

Why does it matter if it a scam????? I'll let you figure that out by yourself. If I'm going to replace it, why should I be contempt with a battery that I have to replace within months (as stated by some people in the comments). The issue here is not if I should or not replace it OBVIOUSLY I'm going to have to before it starts going crazy. The underlying issue is why is the replacement battery for a lack of better words " a bit crap." It comes with a 3 month guarantee?? Is that a joke?!??!?! Some people complained it malfunction after only 8- 9 months? I'm sorry but as an Apple fan I think it's absolutely rubbish. I know there is no magic cure I'm just hoping someone shines the light on how crappy this replacement is.

TS4088 why is there a limit on 3 years? it should be all the MacBook Pro mid 2010 with symptoms, there should get their logic board changed for free, mine mac is 3 month late and i had this problem for over a year, but i first saw this article today :(

Hey Clintonfrombirmingham
I called Apple technical support in Denmark, but with no positive reply.
She couldn't do anything, and said that They had sent a recall Email about the problem and with their offer to repair the Macbook Pro, but I'd never recieved an Email about the problem. She wasn't in power to make an exception. It can't be true that i paid a lot of money, for a product that can't barely stand on its own feets, Apple didn't tell me that the product I was about to buy, would restart every 5 minute. and now when they know the problem, they wont repair it? it just don't make sense for me. If a car seller discovers that all the brakes in a car he had sold, will crash after some years he will call all the cars back to repair no mater what. i just don't understand how Apple will make good service for their custumers, by extending the warranty from 2 to 3 years, but wont take the computers there is a little bit to old, 4 months will make the difference. i can't believe it.
What can i do now?
best regards Oskar

Renewing a Late 2008 MacBook Pro: hard drive and battery substitution

Hi all,
I am an happy user of a late 2008 MacBook pro.
However, with the passing of time, it became slow and the battery also deteriorate (it still quite OK, but it is not like at the beginning).
But let's start from the beginning: the hard drive
By googling for a while, I noticed that several people experienced very slow performance of their late 2008 MacBook Pro. That is also my case. Apparently, this is due to the hard disk which is dying, and then I considering to change it. However, I haven't found answers to these questions:
- Is it possible to mirror all the containt of the current disk to the new one?
- I only have the original installation disks of the first Leopard. I made all the updates through the network. Moreover, since it passed lot of time, I am afraid that some sector of the installation disks may be damaged. This means that I may fail in the installation of Mac Os X on the new hard drive. If I have to reinstall everything from scratch with the new hard drive and without installation disks, how should I do?
- If I go a Mac Reseller shop, will do they perform this operation? And how much does it costs to make it? Or I may also go to some generic computer reparation guy?
- Is it convenient to save all the data (movies, documents, pictures, emails, etc) somewhere (e.g. external HD) and then perform a completely new installation?
Next, let's consider the battery.
Here is a screenshot taken with iStat Pro:
Do you think it is worth changing it? From System Profile I have those other info:
Full charge capacity (mAh):          3386
       Current (mA):          846
       Voltage (mV):          12029
Condition:          Replace soon
What do you suggest to do then? How much does it cost a new battery? Actually, I think that also the processor performance deteriorate (it often becomes very hot, especially when watching Flash or Silverlight stuff), but, unfortunately I cannot change it.

Hi!
Thanks for all the answer. Please let me to resume this old and interesting discussion.
After having evaluated several solutions (including NAS, different ways of backup, etc) I bought an external firewire HDD, since I believe it nicely fits my necessities. Next, after these holidays, I will finally replace my old HDD with a SSD one. I think 120 GB are ok. I just need the apps and small-sized documents (rather LaTeX, Matlab, word, pages or excel documents, etc. - no movies or mp3 (I have Spotify, for that) ). Large files (e.g. movies, pictures, etc) may end up in external firewire HDD.
Now, let's consider the OS. I currently have 10.6.8 and I am very satisfied of that. I find it very stable, and all the apps I need are still well supported. On the other hand, given that there are like 5 years that I have the same installation, I may have a lot of obsolete files and setting that I can safely remove. This means that once I will have performed a backup of my documents, my email, my pictures etc. I can safely throw away all the rest. Hence, I may perform a brand-new installation of the OS. Although I am happy with 10.6.8, I was wondering if it is worth to upgrade it (I have a 2.53 Ghz Intel Core 2 Duo - 4 GB 1067 Mhz DDR3 RAM) to Lion, Mountain Lion or Mavricks. In that case, which would be the real benefits? And what about the cons?
Finally consider that I only have the Leopard installation disks from 2008 (not even Snow Leopard) and I will bring my laptop to a techician to change the HDD (I know, it is simple but I don't have all the screws etc. and I will not buy them only for this purpose). Once he will have replaced the HDD, will he re-install the OS also? Or I have to reinstall the OS through my original DVD (5 years old, I don't even know if they still work) and upgrade to Snow Leopard again by myself? I would exclude the carbon copy solution since I may want to throw away a lot of garbage and perform a brand new instalation of the OS. How to proceed? Thanks again!
