My MacBook Pro 13" won't turn on 90% of the time I try to get it running, and when it does turn on, even on a charger, it shuts down if I stop using it for 2 seconds and it won't turn back on. Should I replace the battery?

My MacBook Pro 13" won't turn on 90% of the time I try to get it running, and when it does turn on, even on a charger, it shuts down if I stop using it for 2+ seconds and it won't turn back on. Should I replace the battery? It doesn't hold a charge either...

EmadJamal,
the battery won’t melt because of long connection to the AC charger, although that has the potential of reducing the battery’s life.
Do you have access to a second 60 W AC charger to test with your MacBook Pro, or access to a second 13-inch MacBook Pro against which your AC charger could be tested?

Why does my Macbook Pro run slow if it's not on the Charger?

My macbooks running terribly slow and I've tried everything. The only thing I've noticed is that it runs faster on the charger. The mouse is super laggy and it's been like this for a couple weeks now. I restored my whole computer, clear cookies, ran updates, cleared disks, etc. Has anybody else had this problem before?

Try a smc reset:

Follow directions for a battery you should not remove yourself.

My Macbook Pro 2012 won't turn on. Tried CMD R and re-install Mountain Lion. Now I get always get a message: Macintosh HDis damaged. But when I repair HD, It says it's OK. What Can I do? I've been with this all day. Replace HD?

Tried as wel PRAM. CMD +S. Tried D key and it blocks when testing... I' going mad!!!

Guess your harddrive is busted. You'll have to get it repaired.

How can I erase the data on my 2009 macbook pro that won't turn on because of a faulty motherboard? Do I just remove the hard drive, install it in a working mac, and erase it that way?

You put the internal drive in an enclosure. If you choose to keep the drive, you don't need to erase it.

My MacBook Pro 2009 won't turn on. It suddenly won't charge and when it did I shut it down and now it won't turn back on. Charging shows green and the green little dots are showing on the side. I tried smc reset, command p r, what else?

A four year battery could be dead. I'd contact an Apple Service Center.

HT1338 my macbook pro airport won't turn on! What would be the problem?

my macbook pro airport won't turn on! What would be the problem?
I've tried to turn the airport on and it says my airport card is not installed...
it has always worked till today... bot from now on nothing seem to help the airport work...
Please help me!
Thanks

You could try deleting the airpot from the sidebar of system preferences/network. To do this,
1) export the preferences for your airport to your desktop by pressing the gear next to the plus and minus sign above the lock.
2) Delete your airport from the sidebar using the minus sign while the airport is selected.
3) After deleting the airport, apply the changes and then press the plus sign to create a new airport.
4) Then import the preferences back in and apply the changes again.
This may bring your airport back. It worked for me. Alternatively, people have been having success with changing the location of the airport.
Good Luck.

The battery's probably drained and the power brick on the fritz. Unfortunately, if she won't start there's little we can do for software-based diagnosis. You'll have to take it in to a Store or Service Provider for assessment.

When i use the macbook pro at home, do i need to use the charger or the battery, which is good to the battery?

My Macbook Pro (2008) won't turn on. No backlight, only still white light on opening button.

So my MacBook Pro (2008) wont turn on, it's battery usually lasts around 30 minutes - 1 hour when fully charged.
I turned it off last night, running fine. This morning I came to turn it on and there was no response other than the white light on the opening button, not flashing just still.
I've plugged it in to charge and have tried about 4 times, each time the backlight makes no change (just black) and the opening button light stays on.
No idea what to do, I haven't recently backed it up and have lots of important files i need.
Any help would be excellent. Thanks!

I am also having this problem. I have tried resetting the SMC and NVRAM. When I press the power button the optical drive makes a noise, the fans come on (not loud), and the hard drive spins. The white light on the front (early 2008 Macbook Pro) also stays on. If I press the caps lock button the light does not come on. The battery takes a charge (all the lights will light up when the button is pressed) and the power adapter shows a solid green light. No changes in hardware have been made in over a year.
Shy of taking the thing apart, any ideas? I live 5+ hours from the nearest Apple Store.
Thank you anyone for the help!

My MacBook Pro screen doesn't turn on when I the open lid.

So I bought my 13inch MacBook Pro Retina two weeks ago. 70% of the time when opening the lid the screen will not turn on but my keyboard backlight will. I then have to either close the lid and open again or press the power to put the system to sleep and wake again. It seems the system is working fine just not the screen.
I have tried the SMC and PRAM reset which seemed to work for half of the day, now the problem is back.
Has anybody got a solution for this or are in fact experiencing the same problem?
Thanks

You've 90 days of free phone support from date of purchase and - at least - a one year warranty on the computer (free phone support and warranty for three years if you purchased AppleCare). The behavior that you're experiencing is not normal - if I were you, I would get on the phone to Apple and have them make you a 'genius bar' appointment.
Good luck,

MacBook pro still won't back up, not even with a cable.

I backed up my G4 tower wirelessly. I backed up my G4 Powerbook using an ethernet cable to the Timecapsule LAN port. (Of course now that I've upgraded to 10.5.2 neither of their airport cards works anymore. No fix for that so far.)
But the MacBook Pro still won't back up. Not even with a cable. I've tried using the cable to the Timecapsule's LAN port. Nothing. I've tried connecting to the Timecapsule's ethernet port. Nothing.
In fact, when I go into network preferences....ethernet is not even an option for connecting to anything. My choices are: Airport, Bluetooth and Firewire.
Exactly how am I supposed to back up my MacBook Pro? It won't do it wirelessly and I can't do it with an ethernet cable either.
Timecapsule POS!

Hmm...let me see if I can help you. In your Network preference pane, click on the '+'. Then select Ethernet from the drop down menu. After you click OK, you should be able to configure the ethernet interface to connect to your TC. After that, you should be able to connect to it with the your ethernet cable.
As far as your not being able to use your MBP's airport, I'm not certain what that particular problem is - I haven't had any problems with my TC and this MBP that I'm using (indeed, my problem is connecting wireless with my PB G4 (with WPA that is, it'll work using WEP)).
Hope my first paragraph helps you.

My computer won't turn on. When the charger is plugged in it flickers between yellow and green

I was using my MacBook pro felt it charging and asleep for 4 hours. I came back and it won't turn on. When the battery is plugged in it flickers between yellow and green.

First thing to try would be resetting the System Management Controller. If that doesn't fix it you are probably looking at a hardware issue. Carry the computer in to an Apple store or service provider, or call Apple to set up service.
Best of luck.

My MacBook Pro Retina won't turn on! Yesterday I installed the new updates.

So it's fully charged. I used it without any problems last night, then shut it down. This morning when I tried to turn it on, it won't. I have Lion installed and am up to date with all of the software updates. There is a green light in the AC adapter. What should I do??

I know this post is from back in September of last year, but I wanted to comment for posterity to say what worked for me with my July 2012 retina MBP refusing to turn on. From the link preludio posted above: http://support.apple.com/kb/HT3964?viewlocale=en_US&locale=en_US
Use the "Resetting the SMC on portables with a battery you should not remove on your own" method (ie., for all Macbook Pros early-2009 and later). Worked perfectly for me:
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if it's not already connected.
On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
Release all the keys and the power button at the same time.
Press the power button to turn on the computer.

Macbook Pro 2011 won't turn on (RAM issue?)

(Macbook pro 2011) I had water damage so I sent in to apple for a complete makeover and they pretty much replaced everything. The laptop seemed to be working fine but the issue is that when I put my laptop to sleep / turn off it won't turn back on. I haven't had the time to take my laptop back to the apple store due to projects / travelling. I've found that there is one quick fix, manually resetting the ram by taking the RAM chips out for a second then re-inserting them. The other way is to hold Command+Option+P+R 3 times before reboot and that'll work temporarily for a day maybe. I plan on taking it to the apple store in a day or so if the problem doesn't resolve itself. Do you guys have any suggestions?
Thanks,

Reinstalling OS X Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. 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 main menu.
Reinstall OS X: Select Reinstall OS X and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
