Same Update Keeps Showing Up

[Anpippin]

Hi everytime I check for a system update it keeps showing the Macbook Pro EFI Firmware update 2.7 and when I click install one item it takes about 10 seconds then my computer restarts and goes to the grey screen and acts like it is installing then boots up normal.

It needs to be connected to power to update the firmware. Update won't work when on battery power, which is why it keeps reappearing.
