Electrical power interruption plus ACARS log on requests do not imply pilot suicide, or hijacking.
Boeing 777 aircraft are engineered to self regenerate systems after catastrophic power failure without any human intervention.
Here's a non-exhaustive bunch of electrical failures to Boeing 777 and Boeing 787 aircraft including some with transponder failures & cockpit
