Hi All I have a Macbook Pro Santa Rosa 2007 EMC2136 that i got lately and i am having the following issue :

  • If the AC (85w) is plugged in without the battery inserted, the device won’t start (no contact or noise)
  • If i place the battery and start up the computer = Starts and boots great
  • If i leave the battery and plug in the AC = Starts and boots great If i take off the battery while AC plugged (with Macbook shutdown) it starts up great but if i unplug / replug AC afterwards = No contact or noise It’s pretty weird Hope someone can help out ! Thanks and good day :)

Have you verified you are using an 85 watt adapter? If so, then see if you can find another 85 watt that you can try and boot with. I have only heard of this problem happening with AC adapters that are starting to fail or are below 85 watts.
