If you find that the trackpad on your Intel-based Mac notebook becomes unresponsive while connected to the AC power adapter, try the following steps to resolve the issue.

  • Try disconnecting the MagSafe connector from the computer and check the trackpad function. If the trackpad becomes responsive again, improper grounding may be the issue.
  • If a two-prong AC plug is being used with the power adapter, try using the three-prong power cable that shipped with your computer and plug it into a grounded outlet.
  • If the issue persists, make sure the third prong is present and do not use an adapter to enable the three-prong adapter to be used in a two-prong outlet. Note that the ground in the three-prong outlet may not be connected. This is common in older homes or buildings with replaced outlets. In these situations, the three-prong power cable will not improve trackpad responsiveness.
  • If a grounded outlet is not available, rest your palm on the palm rest when using the trackpad. This should enable the trackpad to function properly.
