Howdy xVaGuEx,
If your MacBook Pro is shutting down unexpectedly durning startup, I would suggest that you troubleshoot using the steps in this article -

Macbook Pro won't boot past grey screen with Apple logo and then shuts off
This is a long story...
This morning, I would turn it on and it'd go to the grey screen with the Apple logo for a few seconds and then go to the icon that is a circle with a line through it. After reading online, I was able to boot it up in Safe Mode. I messed around a little bit in system preferences thinking I could fix it on my own, not really knowing what I was doing (I'm a *******). I went to Startup Disk in Preferences. I chose the MAC OS X, xxxx and then clicked the lock to prevent further changes and then clicked restart.
Now when I turn on the macbook, it goes to the grey screen with the Apple logo for at least two-three minutes and then just shuts off. Won't boot into Safe Mode now. Please help. I already tried the Command-Option-P-R keys trick like five times.If you have a full retail DVD for 10.6 you can boot from that by holding the C key during startup...but you will then be in install mode if that is what you want to do. At least go ahead and see if it will boot ok from the 10.6 disk and then you can decide what you want to do further.
Apple does not have 10.5 for sale anymore from what some other users have said on here so if you want to go that route you will have to find a copy for sale such as from eBay or one of the Mac resellers.
Before taking the machine to someone, try booting from 10.6 and see if that works...that way you can narrow down problems the machine may be having. -
My MacBook Pro mid 2010 was upgraded to mountain lion os x and then my wifi started saying no hardware installed
Hello Harrisonhcue,
I would be concerned too if I was getting the message "no hardware installed" when trying to use Wi-Fi on my MacBook Pro. For a message like this, I recommend resetting your System Management Controller (SMC) and NVRAM.
Resetting the SMC on portables with a battery you should not remove on your own
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
Shut down the computer.
Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its 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.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
You can find the full article here:
Intel-based Macs: Resetting the System Management Controller (SMC)
http://support.apple.com/kb/ht3964
Resetting NVRAM / PRAM
Shut down your Mac.
Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.

My ipad is flat and when I plug it in to charge it just repeatedly turns on and then turns off but isn't charging. I tried to plug into itunes but it just goes through the same ritual and can't maintain connection to itunes. What should I do ?
1. Reset iPad
2. Try another wall socket
3. Try another cable (make sure it's an original Apple cable)
4. Try another charger (make sure it's an original Apple charger)
5. Clean Lightning port with compress air or new paint brush -

I need to repair my start up disc so I have to start up from installation disc. In doing so, my computer restarts, I hear the mac sound, then a grey screen and then turns off and goes on in this cycle endlessly. Why can't I restart from disc?
Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple
logo appears.
5. Wait for installer to finish loading. -

Macbook pro 17 starts but then just turns off
My 17 in macbook pro starts with the chime, shows the apple, but then turns off before it goes any further. This happens whether using just the battery or just the power adaptor or both.
More info: Below the apple symbol, there appears the spinning icon and below that an approximately three-inch empty bar that starts to fill up with black from left to right but only gets a fraction of an inch before the computer shuts down. I assume that filling bar is indicating the beginning of the start-up process.
I can 'slave' the computer to another working one and see all my data and so forth. But on its own it simply shuts down.
I have tried starting in 'safe mode' but the same thing happen, with all the same start-up icons and then it shuts down. I have tried holding down command, option and P and R together. Same result.
Any suggestions?
What is my problem?

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.

So I have recently replaced my old HDD with the new Corsair 128GB SSD and everything was great. The installation was fast and it worked flawlessly.
One fine morning, it refuses to start. I press the power button and it would just start for 1 sec then turn off. I opened the macbook pro up and put back the old hdd just to see whether its the SSD but even then it wouldn't start up.
Any idea what could be wrong? I have double checked all the wires and everything which looks fine. Please help!Insert the Applications DVD that came with the MacBook, press D key when your computer starts and run the extended test two times. If you haven't got a DVD, press D key when your computer starts
