When trying to attempt to boot it, press the trackpad. If it clicks, the MacBook is coming on (but is not displaying picture, chiming or another issue), if not, the MacBook is completely dead, which will be an issue with the logic board. The force touch trackpads will only click when the MacBook is on, so this is a good indicator when diagnosing these. Remove the logic board and check it for any liquid damage. Remove the tape at the top of the board (this covers components, sometimes liquid is underneath this. Clean any liquid with 95%+ isopropyl, but before cleaning, take a picture for reference, so we know what area was affected by the liquid (if the clean doesn’t resolve the issues.

Holding down the power button for 10 seconds and the p and r key thing don’t work and don’t feel comfortable opening the back.12My solution: use right (more powerful 85 watt) power adapter. I tried all of the above after my MacBook Pro 15” (mid 2102) died as I was working last night. I am in Montreal on a business trip, and fortunately there is an Apple Store two blocks away that opened at 8 this morning. Turns out I brought a 65 watt charger with me. My battery at 100% is now just 43% of original, and got to 0% charge—so wouldn’t boot up on the 65 watt charger. It did resurrect at the Apple Store on an 85 watt charger. The store didn’t have one in stock, but very helpfully looked up that there were three 85 watt chargers in stock at the local Staples store (in French called “Bureau in Gros,” which I’m guessing translates to “Wholesale Office.” Anyway, be sure you brought the right charger if your battery is old.1

Completely dead MacBook Pro, won’t turn on. I was using this MacBook Pro. I bought it over a year ago (so no warranty anymore) at an Apple store here in South America. Not showing life at all for a week. I tried switching the battery from my older Macbook Pro and Voila, here we are. Insidentally, for ‘the proof of the pudding’ on the ‘mind
There are 12 versions of this model – yours is a 2012? Newer models will not boot if there is no battery present, and that battery must have about a 15% charge. Try a different battery before you blow up your board fooling with it. Start with the easy, basic stuff; work toward the harder, more expensive solutions. If this answer is acceptable please remember to return and mark it .12No joke I banged on all for corners. It worked. Knock on it like you’d knock on a door. Not too hard but not too light.13The misinformation here is mind numbing. a) It is the opposite – newer models will turn on with no battery, and when you plug them in they will turn on by themselves. Only certain older models required the battery to be charged to turn on. b) No you do not BANG it to make it turn on, this is BS. c) Measure PP5V_S5 and PP5V_S3 voltage rails.10The newer machines do not come with a system installation DVD. Your machine shipped with 10.7.3 installed. To reinstall the system or run Disk Utilities, start up holding down the Command and R keys. Here’s how to do it: http://www.apple.com/osx/recovery/4I had same exact problem. Banged its corners against a table, and it fired right up. I bet it’s connector corrosion.4Well, I know it is bizarre but my relatively new (late 2015) MacBook pro failed on me twice during last month. In both cases, I became desperate enough to A) buy a set of screwdrivers to open it up B) send it to an authorised apple centre But I did not perform above actions, instead, done the following that worked for me on both occasions. As said I had no option to try on and ALL other solutions didn’t help me at all including resetting SMC. So what I did was, I put my hand on the keyboard with a gentle pressure and moved it from right to left, in a way that it pressed a number of keyboard’s keys at the same time. AND IT worked !!! Whether there is a lose connection underneath OR the move triggered a specific combination of keys that has not been published, I do not know. But I do know it worked for me twice. So give it a try, it might help you too !4Ok. So bizarre. I just did the bang corners (didn’t work) then the keyboard-rub thing and I’ll be dammed — freaking thing booted. Amazing!2Hi, today my MacBook Pro (mid 2012) don´t startup, no lights in the charger, etc, It was completely dead. So I read some of the comments here and I decided to open it Here is what I did: 1) I removed the battery 2) without the battery I connected the charger and immediately saw light and ripped – – I turned off the computer and after cleaning the dust a bit 3) I put the battery back 4) I connected again, yes there was light but it did not start 5) I kept the start button depressed for 10 seconds, I released and pressed again – – the machine returned to normal. Hope this helps to some others.1Today is May 12th 2018, banging on it with my hands worked..2012 mid. Retina. .lmao I still don’t believe it1Angela I think your problem is not the battery (which you’ve already replaced it with a similar one) but your HDD. If you have practice disassembling the hardware of your HDD and turn on the computer with a USB where there is an Apple OS (on the internet you will find many articles to create one). At this point if the computer is turned on you will understand that the logic board and battery (perhaps very used) are good and you’ll only have to reinstall the OS on a new hard drive! 😉0

If you’re using a Mac Pro (Late 2013) make sure your displays are connected to the right ports. If you’re using a display hub, switchbox, or “KVM,” try connecting your display’s video cable directly to your Mac instead. or Thunderbolt 2 (20Gbps).
