MacBook – battery capacity indicator button not working

batterymacbook pro

i have this button (battery capacity indicator) in my macbook pro 2011 series that shows battery capacity, but when i press it nothing happens.

can i know if it is plugged in or not via a terminal command?

e.g.: ubuntu have 'lspci' command to know the plugged in devices

or how can i know if it is plugged via hardware disassembly ?

Edit:

here is how the button look like, its on the left of the macbook

Thanks

Your indicator light seems broken and is pretty much hardwired. Did it ever see any moisture? Replacing it is a relatively difficult procedure, as seen in this video. You will find more guides on iFixit (e.g. this one) explaining how to get to the Battery Indicator Light. But I don't know where you could get a new one if yours is broken.

If you are looking for a terminal command to get your current power status, use pmset. pmset -g batt will tell your the current power source and remaining battery capacity:

$ pmset -g batt

Now drawing from 'AC Power'
 -InternalBattery-0 99%; charged; 0:00 remaining
