I am A+ certified and have fixed many computers and laptops but i am stumped with this one. My little brother has an HP Envy 17t-2100 CTO and it is overheating. I have cleaned it from top to bottom and have replaced the thermal paste and have reinstalled Windows 7 64bit with all the latest drivers and updates. When I replaced the thermal paste I noticed something odd with the design. On the bottom is a small intake vent for the cpu fan and on the rear is a second intake vent. When I shined a flashlight in it to see if the back vent was clogged with dust I noticed it was blocked with a plastic door. This was odd because in the service manual for the laptop that was not there. I opened it back up and their was a plastic door blocking it and it was even held by a screw. I removed it and the laptop stays a bit cooler but still overheats. With Internet explorer open and windows update checking the cpu temp got up to 80c and the motherboard was at 88c. At those temps i quickly turned it off to not allow any damage to the computer. What should I do to fix this issue because I am stumped. Here are the laptop specs for assistance:
Cpu: Intel Core i7 2820QM 3.40 GHz
Storage: Intel 300gb SSD
Graphics: Intel HD graphics and AMD Radeon HD 6850m
