Hartlett has served his three-week ban for rough conduct handed down in Round 21 and should be named in the Power's team to play Collingwood in the second elimination final on Saturday night at the MCG.
Dom Cassisi's tackle on Carlton skipper Marc Murphy was investigated and cleared by the AFL Match Review Panel on Monday afternoon.
The statement issued by the Match Review Panel stated the impact of Cassisi's 'sling' of Murphy to the ground had insufficient impact to constitute a reportable offence.
No further action was taken and Cassisi will be available for consideration at Port Adelaide's selection table on Thursday.
It is more good news for selectors following confirmation a close to full list would be available to take on the Magpies in the knockout final.
"We look like we'll have everyone available apart from Reddo (Jarrad Redden), and Brett Ebert who is now retired," said Port Adelaide senior coach Ken Hinkley.
"We have a really healthy list to pick from, which is good.
"It makes selection not difficult but interesting and we've got to make sure we tr nd get the best people who are going to give us the best chance against Collingwood this week."
