Hi HarmitClaire,

Welcome to the Apple Support Communities!

I understand that your MacBook Air is not charging as expected. In this situation there are troubleshooting steps that I would recommend. Please use the attached article as a resource for steps to help you resolve this situation.

My battery is not charging

Confirm the correct wattage AC adapter for the computer. A power adapter rated for a lower wattage than is required for the system may not reliably charge the computer. For assistance identifying the proper adapter, review Intel Based Mac notebooks: Identifying the right power adapter and power cord--US. Additional adapter troubleshooting is available in Troubleshooting MagSafe adapters. If issues persist please reset the SMC.

Best regards,

Joe
