Q: MBP - blinking green light on power adapter

I think this article may address your situation.

About the battery indicator lights on MacBook (13-inch, Aluminum, Late 2008) and MacBook Pro (Late 2008 and later) - App…

I'm so sorry! I posted the wrong article. I ruled that one out and copied and pasted the wrong url. Perhaps this will be of more assistance.

EDIT: I cannot get that link to post correctly. It's not my day.

There have been some issues with getting web page URLs to work in these ASC discussions

and some work OK, others don't. Some require extra effort and at times, I will paste the page

address that is not working here into a Search engine such as duckduckgo to see the results.

Following, provided me a working URL to article you were looking at. I checked back to there

(visited their site before, did not bookmark) by using the search engine method for good URL.

That may be of some help in presenting your idea. A few other pages from Apple Support

such as About Batteries, Troubleshooting Power Adapters, reset SMC, reset NVRAM, etc.

All of which may help when dealing with the power systems in a portable intel-based Apple.

The issue of the blinking light on the power adapter may point to the MagSafe DC-in Board

that supports the adapter and completes the final connection within the MacBook. This part

could be defective or the electrical contact pins may not be making a good connection.

• Apple Portables: Troubleshooting MagSafe adapters - Apple Support

• About Mac notebook batteries - Apple Support

• Reset the System Management Controller (SMC) on your Mac - Apple Support

• How to Reset NVRAM on your Mac - Apple Support

And should an expert be required, consider (as available) the services of an Apple Store genius

and/or the services of an Apple Authorized service provider; expert technical advice may require

a customary fee for the shop service time when a repair involved labor plus parts.

• Make an appointment at an Apple Retail Store Genius Bar
• Find an Apple Authorized Service Provider

Hopefully you can resolve the issues; for an inside look you could go to iFixit.com repair guide

site and look at pictures with text about how certain items can be repaired by replacing parts.

Good luck & happy computing!

The link TMHahn posted works, provided you take out the space in "magsa fe/"

Yes, I was able to make it work, tried posting a fixed version

that was reconfigured by this site's software - so after 2x - I

chose one of the alternative routes to supply a working link.

When I reposted a new link, it looked different later and turned

black; and the errors returned. So it looks OK and if you work

on it, sometimes the fixed version will remain working, or not.

A search engine narrows choices to working ones, too; and

their link for some reason continues to work a longer time.

PS: the first link provided by earlier response has some of the

same Apple Support articles that I got from my bookmarks.

Anyway, the jive software does a number on page URLs.
