I have a red dot in the top right on the mac book pro log in screen. What does this mean?
What does the red dot mean next to the battery percentage. This is only ever shown on my log in screen.

You may need to attend first the battery charge condition, then look into 'system information'
to see what battery status and charge/discharge cycles indicate; probably a direct connection.
Depending on these variables and the condition reflected in your system reports, there may
be a need to have the battery serviced or replaced by authorized Apple service provider.
In some systems, the power indicators may not fully be accurate immediately on startup.
