We have had our laptop less than a year and are experiencing our first bit of trouble. First off, it seems that the fan has started running more than it ever has. Almost constantly. Also, we always close the lid when we are not using the laptop. Whenever we open it back up, it makes this weird noise. Any idea what that could be? It is a Dell Inspiron 1525 running XP. We have a wireless network if that matters. We use WindowsCare antivirus, and have our network password protected.
