I was having a mini freakout! Why don’t the apple forums recommend this first? They all get so technical, but this is exactly what I needed. Thank you!

Had a whole process going, 6 macbook pros (big family), Three of them failed the next day, and this post, I swear to all that is good, saved me thousands of dollars :D
I cannot begin to tell you how thankful I am!

While the memory re-seating is a good notion, it didn’t work for us. What did work was carefully following the support article:

Intel-Based Apple Portables: Troubleshooting a computer that will not power on
https://support.apple.com/kb/TS1365?viewlocale=en_US

Specifically resetting the SMC:
https://support.apple.com/kb/HT3964

This device apparently controls a lot of low level lighting and the boot process. Our problems started after the laptop drained its power and shut down, e.g. the first cold boot in weeks.

Following the instructions we unplugged the power cable, removed the battery, and held down the power button for five seconds.

After that, it booted fine.

It’s great being able to get many years of service out of a Mac.

Old tip, but still helpful. I think I can now get another 5 years out of my old MBP. :)
