Bluetooth allow wake computer grey out

Scenario:  Keyboard and Mouse r connected via Bluetooth to Blade 15. When computer goes to sleep, keyboard and mouse doesn’t seem to be able to ‘wake’ the computer up from sleep.  The device manager → Bluetooth → Power Management → Allow this device to wake the computer is greyed out.  CHecked Bios and nothing to toggle / chk that enable Bluetooth during sleep too.  If Keyboard / Mouse r connected via the USB dongle (Logitech) then waking up the laptop will have no issues.  But I don’t want to use the provided USB dongle from Logitech to connect my Logitech MX Keys and Mouse…  since they both are able to connect via bluetooth and the laptop comes w/ bluetooth.
