The MacBook Pro Doesn’t Turn On

When you are working just fine on your mac and find that your Mac suddenly goes dead and does not turn on or fails to reboot then there might be a number of issues which can possibly lead to this problem. Now if you are wondering what could be the reason when your Mac won’t start up then you can follow the solutions provided below along with the problems itself. We have clearly defined below the common question of most of the people having the “Help! My Mac Won’t Turn On!’ problem i.e., How to fix a MacBook Pro that won’t turn on. If this doesn’t help then you can reach out us here and we will surely repair your MacBook Pro, be it any model.

RAM Issues

If your MacBook beeps three times, then there is a RAM issue with your MacBook Pro. In such a case, either you have insuicient 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.

Faulty Power Adapter

If your power adapter is bad, the computer will run o a battery, but it won’t charge. If your battery’s charge is too low, it will be diicult 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 le I/O board. If you have the same problem with a fully charged battery, you most likely need a new logic board.

Thermal Sensor Issues

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.

Faulty Logic Board

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

Dead Battery

If your MacBook Pro’s battery is dead, the computer will run fine o the power adapter but will turn o 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 MacBook Pro With A Flashing Question While Turning On

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 case. You can refer to this article for keeping your computer secure. Now the question is what might be the reasons as to 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 as to how to fix a Mac with a flashing question mark problem.

Faulty Operating System

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

Faulty Hard Drive

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 oen 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.

The MacBook Pro With A Very Faint LCD Display

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 as to why do they get a black screen on their computers aer 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.

Backlight

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 lcd

Ports/Audio

If you lose firewire or ethernet, the only thing to blame is the logic board. Because there are many components of the logic board, many possible symptoms indicate logic board failure. Anyone of these components can fail and leave the others intact. If you lose audio or USB on the le side of the machine, the le I/O board is to blame and must be replaced. Loss of USB on the right side requires the replacement of the logic board. If you lose the use of another component of your computer, such as the display, battery, or even power, and replacing the apparently non-working part didn’t fix the problem, it is possible that the logic board may need to be replaced.
