The AFL Match Review Panel assessed the incident as being intentional conduct, low impact and body contact, totaling a total of 5 activation points and a Level 2 Striking Offence.
That equates to 125 base demerit points which, when combined with an extra 20% loading for his four games of suspension in the previous two years and 43.75 residual demerit points, constitutes a total demerit of 193.75 points.
His early guilty plea discounted the penalty by 25% to 145.31 points and a one-match ban.
Hartlett will miss the Power's Round 11 game against Melbourne at Alice Springs on Saturday.
Hawthorn captain Luke Hodge was also cleared by the MRP for an incident where he made high contact with Chad Wingard.
The panel determined the impact between Hodge and Wingard was insufficient to constitute a reportable offence.
