If your MacBook beeps three times, then there is a RAM issue with your MacBook Pro. In such a case, either you have insufficient RAM to boot, or the RAM you do have is faulty. The solution to this issue is simple. First, you should access the RAM slots and ensure you have RAM installed. If you have two chips, first reset them and try again. If this doesn’t work, you should try one chip at a time to see if one of the chips prevents the machine from booting. If none of these solutions work, you may have a bad logic board. The speed of your computer depends on the capacity of your RAM and the processor. So you should prevent any damages to the RAM as it may slow down your Mac.

If your left MacBook Pro I/O board (Motherboard) is bad or faulty, you will not be able to start your computer when it’s plugged into the wall. It may or may not run on battery and the light on the power adapter will not light up at all (some power adapters do not have lights, so this may not apply to your computer). These symptoms point to a left I/O board that needs to be replaced. At Techyuga we will replace repair your MacBook Pro’s motherboard in a very hassle-free way.

If your power adapter is bad, the computer will run off a battery, but it won’t charge. If your battery’s charge is too low, it will be difficult to diagnose a bad power adapter. The easiest way to test this is to borrow either a battery or power adapter or to test in your machine. If you have the same problem with another power adapter, your problem is most likely the left I/O board. If you have the same problem with a fully charged battery, you most likely need a new logic board.

If the fans run at high RPMs, but the computer does not boot, there is probably an issue with the thermal sensors. First, ensure that the thermal sensors are plugged in. If they are, try replacing the thermal sensors. If this does not fix the problem, the logic board most likely needs to be replaced.

If the above steps don’t fix the “MacBook Pro doesn’t turn on” problem, then you should replace the logic board.

As soon as you unplug the computer from a power source, it may start misbehaving and as a consequence might turn off. Now there might be this question in your mind as to Why does my laptop turns off when I unplug it? or How to fix my MacBook or laptop from not being turned off after unplugging it. Sometimes, there might even be situations when your MacBook claims to be 100% charged but shuts down when unplugged. The possible reason for these issues with your computer is a dead battery. We have defined below the issue and solution to the problem but if that too doesn’t help then you might wanna get your MacBook Pro inspected by experts.

If your MacBook Pro’s battery is dead, the computer will run fine off the power adapter but will turn off when it is unplugged. A dead battery can manifest itself in many forms: It may not accept a charge (this particular symptom may also indicate a problem with the logic board), the computer may not recognize the battery, or the battery may be recognized as charged but fail to power your computer when the AC adapter is unplugged.

The computer displays the flashing question mark when it can’t find a bootable operating system. This could be because your OS is corrupt, the computer doesn’t have enough RAM, or your hard drive is failing. You might even wanna keep your computers secure in such a case. You can refer to this article for keeping your computer secure. Now the question is what might be the reasons why the flashing question mark appears when you start your Mac. There are a few of them that we have mentioned below. Hope it helps you to understand better how to fix a Mac with a flashing question mark problem.

Try booting off an OS CD. Run Apple’s Disk Utility and try to repair the disk. You could also try Alsoft’s DiskWarrior. If this fails, reinstall your operating system. If you can, erase the hard drive prior to reinstalling the OS.

This is quite rare. If you have insufficient RAM for your computer to boot the operating system, you may get the flashing question mark. Installing more RAM or downgrading to an older operating system will fix this. You need 128 MB RAM to run OS X 10.0-10.4, and OS X 10.5 requires 512 MB RAM.

The hard drive may have been erased, corrupted, or damaged. If the hard drive has been erased, format it as HFS+ and reinstall your operating system back onto it. If it is corrupted or damaged, you need to replace it. Failing hard drives can display intermittent data corruption prior to failing completely. They often gradually get louder and start to click. If your hard drive is making abnormal clicking noises but still works, back up your data immediately and replace the hard drive. Any of our 9.5mm SATA hard drives will work in your computer.

Another common issue that you might face in your MacBook Pro is the Faint LCD Display. Usually, when this happens then your screen might look black but you might be able to see very faint graphics on it. Many people refer to this as black screen errors and some also might not be able to understand why do they get a black screen on their computers after a while. Symptoms of this are a dark screen, but everything else seems to be running. If you get in close with a flashlight, you can usually see the image faintly. This problem might be because of the Backlight issue which we have defined below.

If your backlight isn’t working, the inverter may be bad. Other parts that may be bad are the display or the logic board. If your backlight fails intermittently while moving the display, the problem is with the inverter cables. Otherwise, it is impossible to test for damaged parts without replacing them one by one. If you are comfortable taking apart the display assembly, replace the display inverter first, then replace the LCD. If you are not comfortable with this, you can replace both parts at once by replacing the display assembly. If this still doesn’t solve your problem, you need a new logic board for your MacBook Pro.
