2012 Macbook Pro power issues

My 2012 MBP 13" has been having a few weird power issues lately. I can close the lid and it'll go to sleep fine, but when opening, I started getting the progress bar and greyed out screen, along with the superdrive power cycling. I got rid of that for the most part by changing how long it takes for it to go to standby to 24 hours. However, I'm still having an issue where when I unplug it in the morning to take it to work, the superdrive cycles even though the lid is closed and it's "asleep" so to speak. I've reset the SMC a few times, no avail. I've done a search online more than a few times, the only fix I came up with was changing the standby time. Any ideas?

Interesting. Also set standbydelay to 0. Unplugging the Mac still causes the superdrive to cycle and still seeing the progress bar when opening the lid after it's been sitting overnight.

Macbook Pro power issues; Dim charging light, limited power.

So I'm having some serious concerning issues with my 15" MBP while connected to AC power. Recently my AC adapter gave out so I bought a replacement on ebay. While waiting for it to arrive I used a borrowed a 65W charger to charge between uses, which as I understand should not be an issue especially when only charging. At some point the charge light on the 65W began showing only a very dim green. It still worked fine on the Macbook.
Upon receiving my new adapter and plugging it in, I observed the dim light again and decided to try and see what was going on. The system profiler registered a charger present but not charging, but the battery seemed to charge regardless. When using the computer on AC power, battery life would decrease slowly and it would eventually fall into sleep mode when the battery hit zero. Something that seemed to be accelerating from what I imagine to be the battery on its last legs as it had been giving a "Service battery" warning for a few months before this. Eventually the computer began to shut down and attempt to restart immediately on startup with the battery, and operated on AC only, without the battery, as long as I didn't use any applications that demanded high performance from the CPU.
I have tried resetting the PRAM and SMC with no avail.
Well, I just received a new battery in the mail (not that I expect it to fix the main issue), and I'm hesitant to try to charge it.
Basically, what I'm wondering is should I be worried about damaging the new battery with what seems likely to be a damaged charging circuit?
Also, from what I gather, this problem is usually related to the left I/O board where the magsafe and charging circuit is.
Is there any way to determine where the fault is for sure before I go buying replacement parts? My hope right now is that it is in fact the I/O board and not the logic board because of the cost of a new logic board and the fact that I could easily replace the I/O myself.
Any insight at all is greatly appreciated.

Here's a link for troubleshooting the power adaptor:
http://support.apple.com/kb/TS1713
Also check for any debris in the power port which may be keeping the adaptor from making good contact.
It's always possible the power adaptor from EBay is faulty. You need to try a known good on, like a working one that a friend has or one at the Apple Store.
Is the new battery a genuine Apple battery or a third party battery. Third party batteries can be difficult to get working. I have one from OWC that's like that--it takes its time to begin charging instead of starting to charge in a second or two.
The best way to troubleshoot all this is to try a known good battery and a known good power adaptor. Your new ones are still in unknown condition. If you have a friend with the same Mac who has known good battery and power adaptor, you can try those in your Mac--and yours in the other Mac, and narrow down the possibilities.
If the Mac fails to charge even with a known good battery and power adaptor, there's a good chance that the I/O Board is bad. But I don't know of a definitive test that would tell you for sure.
Good luck!

Macbook and Macbook Pro Power Adapters

Is it safe to use a Macbook Pro power adapter in a Macbook and vice versa?
I have just noticed that the MBP's adapter is 85 watts and the MB's is 60 watts. I hadn't realised they were different.
My wife and I share each others adapters all the time (she has a Macbook). Will this be damaging either of the laptops?

Shouldn't cause any problems. The main issue will be that the 60w adapter won't provide enough juice to both charge the MBP battery and run it if there is much of a load so I'd avoid using the 60w on the MBP for anything other than charging the battery whilst not using the machine - sudden power shortage could be painful for the machine.
Best of luck.

Macbook pro shutdown issue

Macbook pro shutdown issue when I push the power button it immediately goes into sleep mode

Hello Marrio22,
Thank you for the question. With OS X Mavericks, the power button has new functionality:
OS X Mavericks updates the power button behavior on Mac computers.
Using the Power Button to Sleep & Wake
Tap the power button in Mavericks to put your Mac to sleep or to wake it up:
Tap the power button once to put your Mac to sleep.
Tap the power button again to wake your Mac.
Press the power button for less than a half a second to sleep or wake your Mac. This duration is similar to pressing the Space bar or Return key to wake your Mac. The power button works this way across all Macs using OS X Mavericks, including both notebook and desktop computers.
Accessing the Shut Down Dialog
Press and hold the power button for 1.5 seconds, to bring up additional options:
Forcing the Mac to Turn Off
Hold down the power button for 5 seconds to force the computer to turn off. Important: You may lose unsaved documents if you force the computer to turn off this way. Use this method of turning off your Mac only if it has become unresponsive for an extended period of time. Normally you should shut down the computer by selecting Shut Down from the Apple menu, or from the shut down dialog pictured above.

Macbook Pro Wifi Issue

I incorrectly posted this in the wrong thread this morning.
I'm hopeful you might be able to help me diagnose a problem I'm having. I'll provide as much detail as possible.
I have a first generation MacBook Pro. As of this morning I was running 10.5.6 and up until this week was using a linksys router and a comcast cable modem.
I used to have a great wifi signal throughout the house (always full strength), and around 12-18 months ago noticed the signal would weaken. The best I would get would be minus the top bar on the signal, and usually only if I was directly above or next to the room with the router. There were no new phones or devices added that might adjust the signal. On the other side of the house, I would have no signal at all.
My wife has a nine year old ibook and has no issues connecting through wifi.
When I bring my laptop to her parents' house or to the Apple store, where they use Belkin on N or Airport Extreme, I get a full signal.
I've recently suffered a hard drive failure and had a replacement drive installed. The problem persists despite the software update.
Not knowing if it was a router issue or an airport card issue or a combination thereof, I went to the Genius Bar. The genius recommended I upgrade my router to Airport Extreme, and if that doesn't work to return it and he'd focus on the airport card or antenna. I could get the flat rate repair (no AppleCare at this point) for $320+ to repair the problem if Extreme didn't work.
I installed the Airport Extreme router and got a full signal in the basement, far side of the house, upstairs - everywhere. Until around 10pm. The signal died from the basement. If I walked into the room with the Airport Extreme router, I'd get a full signal. If I left the room, I'd get a partial signal. If I walked any distance (10-12 feet), the signal would die. I restarted both the modem and router with no change. I reinstalled the linksys router and got a depreciated connection. I restarted the Airport Extreme again and got a full signal throughout the night, morning, through restarts, and when I returned home from work.
Last evening after using youtube extensively it died again. Linksys would barely work if I switched back, and no matter how many times I restarted I couldn't get the signal to last outside of the area of the router. I left it in the basement overnight shut down, restarted this morning, and had a full signal.
I'm looking for any potential guesses as to what may be causing the problem. I don't want to replace the card if it's the antenna or sink too much cash into a machine if it's a heat related issue linked to Generation 1 syndrome.
During all of this the ten year old ibook works fine. I know a lot of macbook pros have issues with their wireless and don't want to sink in the cash if it's more complex than that. Any advice is much appreciated!

Hi nashie1002,
If you are having issues connecting to your WPA2 WiFi network after a recent update, you may find the troubleshooting steps and settings in the following articles helpful:

It may also be worth doing a search for the specific model number of your router to see if anyone has noted any issues with Mavericks.

Can't install windondows 8.1 on my macbook pro - format issue

Can't install windondows 8.1 on my macbook pro - format issue
Running latest version of Mavericks.
Followed the exact bootcamp proceduce.
Have official window 8.1 version on cd.
All goes well until I have to format the 65Gb partition. Disk=0 and partition=4
Can't get over it. Altough I formatted it via a hint found on the internet with "dislpart" in NTFS. Wich also went weel and give the labelname "BOOTCAMP". But still no luck.
I have two questions:
1/ How to start my mac again in normal mavericks mode?
2/ How can I overcome the windows installation issue?
Tried already a lot of hints found on the internet.

First, make a time machine backup. You will need to erase ands reformat your hard drive. I had the same issue. The issue is that you can't install Windows using bootcamp without having the hard drive formatted as Mac OS Extended (Journaled). Do this from disk utility or recovery mode (hold down command and r at startup). Then you have to restore the backup to the hard drive. Then make a usb installer drive with bootcamp and then partition and install. Here's a tip: after you install bootcamp and are in the Windows desktop, go into the installer drive and then go into the bootcamp or support folder, then find a installer that contains the Apple bootcamp drivers. Also, you will need to convert the disk to an iso file. TO MAKE THE USB DRIVE FROM A DISC, USE THIS LINK

I plugged in my macbook pro power adapter and heard a loud bang. I checked the charger by opening it and found out the charger blew the whole mother board up. So i buy another charger, as i live in Egypt, that blew up the same way, please help.

You'll certainly need a new logic board.
If I were you, I would take the machine into your local Apple Store or an AASP and have them evaluate the problems and give you an estimate for repair. If you're out of warranty, be prepared to pay a very high price to get your computer repaired.
Good luck,

Using Macbook Pro Power Adapter on a Macbook

I have a Macbook Pro and someone else in my family has a Macbook. Recently they misplaced their power adapter and started borrowing mine to use until theirs was found. I was uneasy about it, but it seemed to work okay. I know that the adapters are slightly different but will it hurt the Macbook to use a Macbook Pro power supply?

It's fine. The MB will only draw the power it needs. FYI, the MBP adapter is 85 W, the MB's is 60 W.
Hope this helps...

Macbook Pro power supply and grounding.

Hey Apple people. I noticed something disconcerting with the power supply on my MacBook Pro 13" (non-retina)
I have a stainless steel metal table in my kitchen. It is the same type of stainless steel table you find in restaurants.
I have my 13" MacBook Pro in a Speck See-thru case.
The MacBook Pro in it's case is sitting on a Rain Design "M Stand".
The Rain Design "M Stand" is sitting on the stainless steel table.
I am wearing a short sleeve shirt.
I am sitting on a fabric covered chair at the table.
The battery was getting low so I got out my power supply, which is the power brick with the two prong plug adapter.
I plugged this into a power strip and the other end into the computer.
While touching the case of the computer with one hand and leaning on the stainless steel table with my other bare arm. I felt a vibration through the fingers that were in contact with the MacBook Pro. I knew what was going on, and I got really concerned.
I tried an experiment.
I got out the extension cord that came with the MacBook Pro power supply and I changed out the two prong plug on the power supply for the extension cord. The extension cord has a grounding post.
When I plugged the power supply back into the power strip and connected the power supply to the MacBook Pro. I no longer felt a vibrating sensation when I was in contact with the stainless steel table and the computer.
I have other MacBook Pro power supplies and I always use the grounded extension cable with them, because it is located at my regular workstation area. This stainless steel table is located in my kitchen, and I was eating dinner and watching YouTube videos.
Just thought you would like to all know that when you don't use the grounded cable on your MacBook Pro. you become the ground.
Never using this power supply anywhere again without the grounded cable.
Thank you for your time.
Matthew Sievert

It depends on what you are doing. Yes, the power supply can get hot. This is normal.

My macbook pro power adaptor getting heated

Hi
My macbook pro power adaptor getting heated & ultimately melting the coil which leads to power off.
Is there any solution for that.

我刚刚尝试了一下，我的电源适配器也好热！但是不至于融化的温度，可以尝试换一个吧。
I just have a try, I find my power adapter is very hot! But it is not the melting temperature.U can try to change another.

MacBook Pro Power Management Issues and "Broken" Bootcamp

This is not a question but rather a solution I have discovered to a problem I have experienced many times now.
My Core 2 Duo 15" MacBook Pro (non-LED version) has exhibited several issues with the systems power management hardware.
Firstly: Occasionally the system will refuse to turn on. This has happened to me twice, it usually happens when I am running on just batteries. The very first time it happened I was in a meeting and had important data I had to get from the laptop, I was silently panicking. After swearing at my new 2.5 grand pride and joy, I happened to read an old support article relating to older PowerBooks which exhibited the same problems. Apple recommended taking the battery out and then holding the power button for several seconds and then reinserting the battery. This apparently resets the power management hardware feature -- and it worked, and has worked three times since.
Secondly: I have had a persistent problem when running Bootcamp. Sometimes the machine doesn’t go to sleep properly and although it everything looks right it continues to run (and perhaps, like me, you’ve backed it away in your bag and hence didnt notice it burning up. What has happened to me several times is that it literally "breaks" Windows XP. When you wake the computer or turn it back on (if the battery drained) then youll find Windows running PAINFULLY slow. If you press CTRL-ALT-DELETE (to bring up the task manager) I would see that the CPU is working very hard (at nearly full utilization) and it is so occupied that it won’t respond to anything I do at all. No matter what I did (I attempted a system restore, which was a two hour task with the computer running in its "broken" state) nothing would bring windows back to life. The first two times this occurred I was devastated because the only thing left for me to try was to remove the windows partition and install it fresh (thus losing all my files and settings -- although for the record you can still access the windows partitions files through Mac OS X). This ruined a near full day for me each time the computer did this (having a lot of settings and tweaks and installed programs to reapply). The third time this happened I did the "trick" listed above and reset the MacBook Pro's power management hardware. this has solved the problem ever since (two additional times now). I post this in case someone experiencing the same issue searches the forum.
I dont know the technical explanation but obviously there is an issue within this series of MacBook Pro's power management. Perhaps it relates to the "artificial" BIOS the system presents to windows through Apple's EFI system (Windows requires legacy BIOS to operate and all Intel Macs alternatively use EFI, so an extra "trick" had to be added by Apple for Windows to be compatible).

The computer. If two different batteries behave the same way it gives credence to possible issues with the power manager. You can try resetting it with:
http://docs.info.apple.com/article.html?artnum=303319
And verifying the firmware is up to date:
http://docs.info.apple.com/article.html?artnum=303880
And running the hardware test:
http://docs.info.apple.com/article.html?artnum=303081
If nothing seems to help, call AppleCare again, and tell them the battery replacement did not solve the problem and that you tried the above and tell them the results you got.
