Prevent my PC from timing out?

Hi! I have a Windows 7 Dell laptop. My company has set the machine to time out after a certain amount of inactivity. This is a security protocol, but I do not deal with secure data, nor do I have access… I’m just lumped in with everyone. Since I have 2 computers, the PC often goes to sleep and I have to log back in repeatedly. Since I do not have admin rights, is there a way to trick the PC in to thinking that there is activity and thus not timing out?
