Battery status is “not charging” and the light is green. The computer sometimes restarts when under heavy load. I have:

  • Reset the SMC
  • Reset the PRAM
  • Tried multiple chargers
  • Bought a new battery
  • Replaced the MagSafe board I am out of ideas. Thanks!

New batteries (especially cheap Chinese ones) have been known to be bad straight out of the box so if this not an Apple battery that could be the answer. Is there other history here you’ve not shared (dropped, wet, stacked)? Run AHT and see what it finds. Since is is an “under load intermittent issue” you may have to run it 2 or 3 times in a row to get it stressed enough to toss an error. If this answer is acceptable please remember to return and mark it accepted.
