Troubleshooting MacBook Pro Power:



As for replacing that battery, that may not be necessary. Try troubleshooting it.

A. Black Mac Screen:

Go Here: If your Mac doesn't Turn On or Start Up - Apple Support

Using External Devices: Try Resetting the SMC and NVRAM, but this time, using an external keyboard. Connect an external monitor and see if you get an output.

B. Mac Power Issues:

Try a New Charger:

If it is currently charging from a charger, then use a new charger:

• Power & Cables - Mac Accessories - Apple - Select "Mac Compatibility" on the left
• Find the right power adapter and cable for your Mac notebook - Apple Support

C. A Few Links to Refer to Power:

Troubleshooting Mac Power Drain:

Three Things:

I. Boot in Safe Mode:

[Hold Down: shift key, upon boot], In Safe Mode, Login Items do not run at login, certain preferences are set aside, and damaged system files are then reset. So, once booted in to Safe Mode, wait 30 seconds, and then boot up normally seeing if you still get this error.

II. Try a New Admin User:

What happens when you create a new administrator user, and log into it? Do you still get this error? If not, then it is likely an error with the current user. If so, then it is likely an error with your Mac.

III. Reset your SMC and your NVRAM:

Sometimes changes (i.e. Installations) are made to the system and then settings (i.e. for Power) become corrupted, technically. So, reset both on your Mac. So, reset the SMC (Intel-only Macs) and reset the NVRAM or PRAM. It might take three tries. to fix this. So, be certain you have the time to do so.
