Narrative:
Ship xyz inbound was swapped to my gate. I checked the aircraft per air carrier transit check. While checking the logbook, I noticed the crew had written up the APU in the 'irregular' block as 'APU would not start.' the crew also wrote in the 'corrective action block' 'started after warm-up prior to flight.' I started the APU. APU start was normal and operation was normal, so I signed off the item as 'APU operations check normal.' after which I pulled the log sheet and signed an airworthiness release on the new sheet. The aircraft departed. While entering the log sheet in the computer, I noticed the crew had deferred the APU 'inoperative' per the MEL. They made no entry in the logbook to reflect this. The log entry looked like a squawk. They did not write as required 'flight crew placard installed' and they did not enter a flight control deferred number. I notified maintenance control. The maintenance deferred item was removed since APU was operating normally.
