Jerry from Queens, NY

Gary is having thermal issues with his laptop. Leo says that there's a sensor that has probably come off the rails. The fans require suction to work properly. If the case isn't in contact, that could be the case. But more likely, it's just a failed sensor. He should also make sure there's no dust blocking the fans and that there's clean airflow. Leo says that he can turn off the setting that could stop it from bugging him.

Gary from Long Beach, CA

Gary bought a computer from GoodWill that they have put together. Leo says that's a great idea, and he got a great price on it too. But he's noticed that the fan is making noise. Leo says that could be a wire that has gotten in the way, and that could be dangerous. It could short circuit the wire and cause a fire. So Gary should open up the computer and make sure there's nothing hitting the fan. If that's not the issue, then the bearing of the fan may need to "warm up." They can easily be replaced.

Lou from Los Angeles, CA

Lou bought a laptop about six months ago and now it's shutting down after overheating. He tried using a vaccum cleaner to clean out the dust and that worked for awhile, but it didn't last long. He tried a large fan and while it doesn't shut down, he gets a message that the cooling fan isn't working. Leo says that's probably been happening all along. Most laptops have a cooling fan on the CPU and one by the port. It may be that the fan on the CPU has failed. Lou will probably need to take it apart to replace it.

Patrick from Burlington, MA

Patrick's computer fell off the desk onto the floor. Now it makes a loud sound when he boots it up. Leo says to turn it off right away. He should make sure he eliminates static electricity and then open it up the case and inspect the fans. Chances are, one of those fans was dislodged and it's getting in the way of the fan blade of the computer. That could short circuit the PC.
