Macbook Pro doesn’t Start or Boot

Ok, I will be honest and tell you I spilled a bit of Water by mistake on my Macbook Pro and luckily it didn’t go to the internal, which I came to know a lot later after I diagnosed the problem with my Macbook Pro.

Here is what happened: I accidentally spilled some water on the back of the Macbook Pro and the next thing I did was, Force Power Off the Mac(by pressing and holding the power button). I went for a run and came back to realise that the Macbook Pro won’t boot, no matter what I do, the MegSafe Adapter also when connect, didn’t show the full-blown green/Amber light as it normally does, but showed a very dim version of it. I called for remote support Virus Removal by the experts at Virus Removal Australia thinking maybe it was a virus, but after that didn’t work I knew it had to be because of the water.


Since the newer Macbook Pro battery are non-removable, there was no way I could dry it without opening the back case, I have my Macbook Pro protected with the Apple Care, but it doesn’t support Water damage and voids the Apple Care.

Thankfully the water had not gone inside the Macbook Pro and the reason it wasn’t booting was due to some of the booting configuration going corrupt due to the Force Power Off.

Incase your Macbook Pro/Air doesn’t Boot or Start here are some of the tips you can follow to ensure there is no hardware problem with your computer.

NOTE: If you can hear the fans and hard drive and see the white boot screen, see a Flashing question mark, a wait Circle running or any problem where you can see that the Macbook is at-least starting up, this article won’t help you.

Here are the Steps you can Carry out to get your Macbook Pro/Air to Life

Round 1:

Ensure that the battery is charge by pressing the battery monitor button, some Macs have it on the left side, when press, it glows green Leds according to the amount of charge left on your Macbooks, the removable batteries have it on themselves.

If your Macbook has a removable battery, from the bottom of the laptop remove it and wait for 5 seconds and place it again, try powering it ON, doesn’t work? Move ahead.

Round 2:

Disconnect any peripherals connected to the Macbook, Printers, Routers, Keyboards, Mouse and try turning it ON, it goes well, it means that there is a problem with one of the devices connected to your Macbook.

Round 3:

Ensure that the power adapter connected to your Macbook is works, try using a different outlet, use another electrical appliance on that outlet, sometimes, the problem with the electrical supply and low battery can cause the Laptop to not work. Some times the MegSafe Adapters too cause the problem, here is Apple’s troubleshooting procedure.

Round 4:

Try resetting the SMC (System Management Controlled), Shut down and unplug all cables including power cord for at least 30 seconds and then plug in the power cord and power on, this will reset your Power, Fans, Lights, System Performance and Video settings, which may bring back your Mac to life.

Round 5:

Reset PRAM on the Macbook: Hold down Option, Command, P and R while booting. Start it when you hear the chime and don’t let go until it reboots, don’t let go the keys until you hear it for the second time, if you Macbook has corrupted Speaker volume, Screen resolution, Startup disk selection, Recent kernel panic information, this will sort it out.

Round 6:

PMU (Power Management Utility) reset, this is what solved my problem, Power Management is responsible for Monitoring power connections and battery charges, Charging batteries when necessary, Controlling power to other integrated circuits, Shutting down unnecessary system components when they are left idle, Controlling sleep and power functions (on and off), Managing the interface for built-in keypad and trackpads on portable computers, Regulating the real-time clock (RTC)

So issues with one of them must be deterring that Macbook to boot or show any signs of boot, How do you a PMU Reset on a Macbook/Macbook Pro/Macbook Air

Do a ‘SCOP’, Shift + Control + Option + Power, For Apple laptops with a removable battery, resetting the PMU involves unplugging the power adapter, disconnecting the battery, then holding down the power button for five seconds.

If this doesn’t work, you will have to send across your Macbooks to the Apple Repair center and get it repaired.

P.S.: The water that spill on the Macbook Pro wasn’t the problem, honestly and thankfully, the water didn’t seep inside.
