why is my green light flashing dim and my macbook pro will not start
Recently my macbook pro has not been cutting on and the green light on the charger is blinking dimly. What could be the cause?
MacBook Pro, Mac OS X (10.7.3)
Try these steps:
Restart your Mac with the Shift button pressed.
- Shut down your Mac
- Wait until your computer turns off and after that press the Power button
- Right after you hear the startup tone, press and hold the Shift key
- Release the Shift key when you see a grey Apple sign and the progress bar below this sign
- Once you see Desktop, start a Disk Utility scan to detect and repair file system errors (don't forget to choose your main hard drive)
- Click on Verify Disc and then, if asked to fix problems, on Repair Disk
- After this, click on Verify Disk Permissions and then on Repair Disk Permissions
- After the process is finished, shut down your Mac and turn it back on after about 30 seconds
If this will not help Try SMC reset:
