pro. If not, then you need to disconnect the peripheral devices and
then turn it on to check everything goes well or not. By doing so, you can
address the issue.
RAM issues

time or the lights are blinking, then there must be some hardware
failure. Bad RAM is very common issue on newer Mac's. So, to test
this case, just remove one RAM at a time and reboot. Repeat this
activity again till you find the problem. If any of the culprit
arises, then have a look in Mac owner Manual and install RAM.
Bad battery

Macbook. To perform this task, press the battery button or on the
side of your computer. Single light blinking may lead you in the
condition of dead Macbook. So, you need to charge accordingly
whenever necessary.
Operating system

resulting in start up problems. All you need to do is to hold down
the control key, command key and the power button together to restart
the computer. In this scenario, try booting off an OS CD and run Disk
Utility to repair the disk. If this also doesn't work, last option is

Hard drive failure
A major issue is of the hard drive. If
the hard drive has been corrupted or damaged or makes abnormal
noises, first thing you need, is to back up your data safely and
replace it immediately.
Mac's SMC
Resetting SMC is the important feature.
The simple SMC reset can resolve number of failures such as battery
not charging, USB ports and Bluetooth not working, fans running fast,
erratic sleep mode performance, failure to response to power button,
sluggish performance etc. So, to reset the SMC, first shut down the
Mac, disconnect from MagSafe connecter, remove the battery and hold
the power button for 10 seconds. After releasing the power button,
reinstall the battery, reconnect the MagSafe connector and turn your
Mac on.
Thermal sensors not working
This issue is noticed when the fans run
at a higher speed but the computer does not boot. You have to ensure
first, that the sensors are plugged in properly. If yes, then replace
it. If this doen't fixes the problem, you need to change the logic
board.
Faulty MagSafe adapter
To test that the adapter is faulty or
not, one needs to check the electrical outlet and the plugs are
inserted properly or not. If the outlets works smoothly, then unplug
the power adapter for a while and then plug it again. By doing so, if
the power adapter's LED does not light up, then definitely MagSafe is
damaged.
Therefore, fixing these issue in the
appropriate manner will resolve most of the start up problems of the
Macbook pro.
