After powersurge no light on magsafe+no charge. Board or PwrSupply?
Power went out today and the house got got a surge when power was restored. Bedroom light was much brighter than usual for 30 seconds or so. Misc. cheap Household powerstrip got fried+microwave oven no longer works. My MBP17 was running at the time and I didn't think to quickly power down when the power went out. I didn't realize till later that the magsafe was not 'green'. I always run off the powersupply. The MBP and 3 external drives are plugged into an inexpensive 'protected' powerstrip. Had no trouble with any of the hd's. I bought the powersupply a couple months ago, 'reconditioned' frrom OWC. Could it be a bad PS and just bad timing, or maybe a bad magsafe board? I don't have access to another PS. How do you check voltage with those little pins in the T-connector? Different voltage per pin? Or same v accross them all? Thanks for any help!

More info...I tried other sockets on the ps, different outlets in my room and others around the house. I get no light from the magsafe LED at all. The MB ran just fine until the battery ran out. I was playing with garageband until I noticed the low battery, and then realized the magsafe's green light was out. No orange or red either.The battery doesn't last long at all, so I keep it plugged in 99% of the time. I'm hoping the ps is the problem and the logic and left I/O boards are undamaged. I guess I need to find someone with a MBP I can test the ps on...

What are the last 3 characters of your serial number so we can determine your exact machine?

Just came back from a mac store+repair shop. Had the tech plug my magsafe into a much nicer macbook pro...No Light! Power supply is dead.
I'm hoping a new PS is all that I need.

update: The magsafe was dead. I spent a week or so, searching for repair info...Hoping for something simple+obvious. Like a toasted diode, cap or resistor etc. that I could replace myself. No luck.
I found a magsafe on Newegg for $50-$60. I'm still using it in 2019.

i just had the same thing - crazy winds outside, power surge, forgot that magsafe charger is plugged in - now it just won't charge. Have tried replacing the outer module of charger(the one that has the pins that go into the wall) - no luck, tried different sockets - nope. FWIW, my last 4 chars are AATM, it's a 2010 mac 13" and I'm happy with it :( now my battery doesn't last more than 30 mins, so I'm just typing here hoping to find a solution
and hey...you know what, I plugged it out after having tested it many times, looked for chargers on bestbuy - and just before throwing it away, gave it another try. How do I put it... it worked! So yeah, 10 yr old mac (with RAM & SSD upgrades) works fine. again - no one's listening but I'll thank you guys for being the sounding board.
