MacBook pro won't run unless charger connected

Hello
Suddenly my 2 year old MacBook Pro will only boot if the charger is connected, if I disconnect the charger while the computer is running, the screen dims after about four seconds then it dies completely. Puzzling since the battery still seems to be healthy. Any ideas before I take it to the shop? I've been running Snow Leopard with no problems for three months and there are no peripherals attached.

Your battery has completed a fair number of cycles, De Boffined. How long since you calibrated it?
I'd be inclined to check the battery connections for any dirt or corrosion , and reset the SMC (see http://support.apple.com/kb/HT3964 )
If the problem persists after that get the battery tested.

MacBook Pro won't sleep when charging

My 15" i5 MacBook Pro won't sleep when charging; a reboot of the machine solves the problem temporarily, but it always recurs. When I close the lid and listen carefully, I can hear hard drive activity; the drive sounds like it keeps spinning up every 10 seconds or so.
This is not an issue when trying to sleep when running on the battery only. Any advice?

I don't have launch2net installed.
I'm not sure how this will help, but here's the last 5 lines from Console:

My macbook pro won't hold a charge for more than a day...do I need a new battery?

my macbook pro won't hold a charge for more than a day...do I need a new battery? I have a 13" early 2011 model.

A: did you leave most of the time or always plugged in?
B: did you often drain the battery very low?
If so, then thats the issue
From Apple on batteries:
http://support.apple.com/kb/HT1446
http://www.apple.com/batteries/
Storing your MacBook
If you are going to store your MacBook away for an extended period of time, keep it in a cool location (room temperature roughly 22° C or about 72° F). Make certain you have at least a 50% charge on the internal battery of your Macbook if you plan on storing it away for a few months; recharge your battery to 50% or so every six months roughly if being stored away. If you live in a humid environment, keep your Macbook stored in its zippered case to prevent infiltration of humidity on the internals of your Macbook which could lead to corrosion.
Considerations:
Your battery is subject to chemical aging even if not in use. A Lithium battery is aging as soon as its made, regardless.
In a perfect (although impractical) situation, your lithium battery is best idealized swinging back and forth between 20 and 85% SOC (state of charge) roughly.
Further still how you discharge the battery is far more important than how it is either charged or stored short term, and more important long term that cycle counts.
Ultimately counting charge cycles is of little importance. Abuse in discharging (foremost), charging, and storing the battery and how it affects battery chemistry is important and not the ‘odometer’ reading, or cycle counts on the battery.
Everything boils down to battery chemistry long term, and not an arbitrary number, or cycle count.
Keep your macbook plugged in when near a socket since in the near end of long-term life, this is beneficial to the battery.
Peace

17" MacBook Pro won't run on AC power

Ok, this is a unique situation and I have searched the forums and can't find an answer, my early MacBook pro will not run on straight AC power, it will power up and run on battery power and the battery WILL charge while the machine is powered OFF but will not charge while the machine is on, so anybody have a solution?
Will run on battery power, will not run with battery removed on AC Only, battery will charge with AC adapter ONLY when machine is powered down, will NOT charge when machine is on.
Thanks for your help

Ok, booted into safe mode still same results , won't run on AC power, turn unit off light turns orange on power adapter and battery charges as normal, AC adapter plugged in light is green not charging while unit in on and will not run with battery removed, if I remove MagSafe it intermittently turns orange then back to green....Still perplexed as machine knows AC adapters connected and will charge but will not power or charge when unit is on.

MacBook Pro won't start unless I unplug and replug battery

I have a mid 2011 MacBook Pro 15" that has this odd issue. I don't normally shut down my Mac and can be left on for days with lid closed when not using it and always have power cord plugged in, battery usually at 96% or so.
Usually this is fine and don't have problems but occasionally I'll open the lid and it appears that the Mac has shut itself off. When I go to press the power button nothing happens. I have found that if I take off the bottom cover and unplug the battery connector the replug it in after a few seconds the Mac will start up. It will then be fine for days without any issues but it seems to come back inevitably.
So question is what is happening here? Why does unplugging and reinserting the battery cable seem to clear the issue? Any ideas or help would be appreciated.

I have the same issue with my 15 inch early 2011 MBP as soon as it updated to OS X 10.9.4. I have reset the smc, the nvram, checked and repaired any disk permissions, verified the drive which identified no problems, reinstalled the software, replaced the power cable, called applecare to no avail, and my computer will not let me run a hardware test. During the issue it does not read the battery:

I know the computer reads the battery however, because when i turn it on while plugged in and unplug it, the system will start and run normal until it tries to load the UI. The grey screen with the apple icon suddenly turns yellowish and then shuts down. This happens with almost every major software update from apple.

When I play games like StarCraft 2 on my MacBook Pro (without my Thunderbolt Display connected), the game runs GREAT
When I play games like StarCraft 2 on my MacBook Pro (with my Thunderbolt Display connected), you notice the mouse responding slower (I even lowered the graphics settings to it's lowest and still get the same results)

When I play games like Safari on my MacBook Pro (with my Thunderbolt Display connected), you notice the mouse responding slower
The above happens with any application. This even occurs after a fresh reboot. i unplugged all my periphals from my MacBook Pro and Thunderbolt Display
I updated my OS and applications.
I monitor Activity Monitor and notice nothing unsual about runaway processes.
Just so everyone knows. This is a 2011 MacBook Pro.

I have the same exact model as you, as well as an Apple Thunderbolt Display. I don't play any games, so I wouldn't notice any degradation there but I do run a lot of GPU/CPU/RAM intensive apps and have experienced no problems with the TB display connected.
We have the same configuration, OS, everything. We may just be running different apps. I do have 16GB of RAM and a SSD so that may mean that I'm just not able to notice any slowdown at all.
I'm not sure what your problem might be - I would suggest contacting AppleCare to see if they've documented problems such as the one you're having.

Every time I turn my iMac on it will not connect to the internet until I open System Preferences / network / Assist me. that reports that my internet access appears to be OK, and hey presto my web home page appears, and everything if ok. The same happens if I have opened Mail, nothing until I've gone through the above proceedure.
This has been happening for a week.
The iMac uses Mountain Lion.
I have no such difficulty with my Macbook Pro which runs Snow Leopard.
I have deleted the safari caches and logs, to no avail.
Any suggestions would be greatly appreciated.

Try setting up another admin user account to see if the same problem continues. If Back-to-My Mac is selected in System Preferences, the Guest account will not work.

If the problem is still there, try booting into the Safe Mode. Shut down the computer and then power it back up. Immediately after hearing the startup chime, hold down the shift key and continue to hold it until the grey Apple icon and a progress bar appear. The boot up is significantly slower than normal.

Macbook Pro Won't Run Past 1GHz Without Its Battery

Hello,
I've been using a Macbook Pro 2.16GHz for half a year. I just realized that the computer will never get beyond 1GHz, both in Windows and Mac OS (I checked with Sisoft, CPU-Z, and CoreDuoTemp) when I remove the battery and run on AC Adapter. However, when I pop the battery back in, MBP speeds up to normal speed. Is this regular? Thanks.

Hi palmbook,
Dont worry,this is the nature of Macbook Pros or Macbooks.When we are using our mac,the power consumption is not constant but fluctuates instead.At certain moments,the power consumption will go beyond what the AC adapter can supply...when this happens,the battery will have to provide extra power to cater those needs.
If the battery is not present at these moments,the system will simply shut down by itself to prevent any damage to the circuits and thus losing unsaved data.This is imperative for people who are performing rendering tasks as long hours of data processing will culminate to nothing in the event of such "moments".
To address this issue,the SMC(System Management Controller) will limit the usage of the CPU to 50% of its nominal speed if the battery is removed in order to prevent such "moments" from occuring.

MacBook Pro won't run after sleep

After closing the lid it goest to sleep. But when I come back to turn it on I find that the light indicator is on and solid. And when I open the lid nothing will work, screen, keyboard light, volume, even the power button. The only solution I found for this is to hold the power button for about 5 sec then it will be force shutdown then turning the laptop again.
Does anybody know the solution for this?!

I am having the same problem. MacBook Pro will not enter sleep mode (white LED does not pulse but remains steady) and will not "wake up". I end up restarting with the power button. I have verified and repaired hard drive with disc utility. I have also searched for firmware updates; only one available that may be an answer (MacBook Pro EFIU Update version 1.9) is not comaptible with my computer. would appreciate any other ideas anyone may have to solve this problem.

Macbook pro won't turn on , charger cord flashing orange

I Bought this online, used (i know, bad choice) it was low battery soon as I opened it, but I started setting up my account. I plugged in the charger cord and wanted to keep working, but it just shut off suddenly. The light on the charger is a dim green and it flashed orange, I tried to push the button on the far left side lf the laptop, no green light appeared. It won't turn on.

Try Intel-based Macs: Resetting the System Management Controller (SMC). If that doesn't help then make a Genius Appointment and take it in for service.

2013 13" Retina Macbook Pro won't resume properly when connected to external display

Have a lovely new 13" Retina macbook,
When it's connected to my display by a displayport->hdmi adapter and the lid is shut if the laptop sleeps then it will not resume properly. I get a black screen, or a blue screen with a cursor, and I have to reset the macbook to use it again.
Without the display connected it works fine every time ( by lifting the lid ).
Any Ideas?

Had a chat with apple support, and this got fixed
Solution was a SMC controller reset

and a PRAM reset

My early 2011 15" macbook pro won't run AHT at startup when holding 'D' help???

when i first got my macbook 2 month ago after i put all my stuff onto it i ran a hardware test by resetting the comp and holding 'D' before the chime (i think, not quite sure which botton i pressed it was a while ago) anyway i forgot how to do it so i looked online n it said hold D when restarting, so i did this and nothing happens!!?!?! any advice please?

Since you are using Lion, you better read this thread - https://discussions.apple.com/thread/3217292?start=0&tstart=0 or post in the Lion forum area.

Macbook Pro won't run on new battery

Okay, so I have this 17" MBP, late 2007 vintage, gotten refurbished in 2010. The battery, which was at about 700 cycles as of last week, swelled and was somehow still working up to the point when the new battery got here and was put in. That's fine with me, it's a refreshing change from the oodles of power cords I've gone through in the last several years. HOWEVER. The new battery, purchased off eBay from a highly-rated seller, had a cycle count of one when I installed it, and is now causing me problems. The couple of times I had it off the power cord right after putting the new battery in, it behaved a little erratically, shutting down in the thirty seconds it took me to change locations with it, but I didn't worry myself about it.
I had it off the power cord earlier today, and it was fine for half an hour or more, but then shut itself down abruptly. When I plugged it in and rebooted, it was showing the battery at about 50%. I did a little research and reset both the SMC and the PRAM, in the hopes that maybe it was just an issue of not really recognizing that it was a new battery yet. Immediately after those resets, during a bootup without being plugged in, it shut itself down before even completing the boot. I'm really hoping it's just a fluke with the new battery, and not that some other aspect of the MBP is failing, but I figured I'd ask around here before contacting the eBay seller.

If you did the SMC reset and no love, take it up with your highly-rated seller.

Hello Rattisate,
Sorry to hear you are not able to connect to Wi-Fi on your MacBook Pro. I would be concerned about this too. You can find information on how to troubleshoot this in the following article:
Troubleshooting Wi-Fi issues in OS X Lion and Mac OS X v10.6

My MacBook Pro that is running on 10.6.8 won't update software so that iTunes connects to my iphone 6. Problem is that when I go to update, it restarts the computer but never updates any of the software.

My MacBook Pro that is running on Mac OS X 10.6.8 won't update software that I need in order to download the newest iTunes software to connect to my iPhone 6. Problem is that when I go to update, it restarts the computer but never updates any of the software.

In addition to Stedman's spot-on reply --
When you buy an upgrade disk, all updates in that OS can be found on Software Update.
For instance, I bought Snow Leopard at 10.6.
All other updates have been free and downloadable. So I'm not a 10.6.7.
10.4 (Tiger) went to 10.4.11.
10.5 (Leopard) went to 1.5.8
10.6(Snow Leopard) is currently at 10.6.7.
Now, when Lion come out (the next major upgrade of OSX), I will have to pay to go to 10.7.
After that, updates are free til 10.8 comes out.
