Why my laptop is over heating?

Just to chime in on the great answer above. The inspirion is a budget laptop, great system and the more budget sensitive the lower dollar figure rolled into production of this off the assembly line. The design is not perfect and dust will become a challenge even down to the connector that you connect for power. A particle, in my past history, has kept the charge from fully taking place. One day if they decide to use modify things, they should use the power cord for the Latitude. Used one for work and my woes went away. Become ninja like in terms of breaking the system down and cleaning. use anti static mat and appropriate tools and have service manual close by and ensure your grounded when on the interior. best EM TEXAS
