Need program to keep Dell Laptop with windows 7 from sleeping

I am working remotely with a 3-month old Dell laptop in a Dock. Even though the Control Panel has been set to never go to sleep, the computer will sleep if left on overnight.  I have just set up DropBox, and need a lot of files to synch overnight.

Is there an program that I can put on the computer that will keep it busy and prevent sleep?   I don't have time to call Dell support right now.

Thanks.

Go into the Advanced Power Options in Windows and look at Sleep options. Make sure Sleep is set to Never and then make sure Hibernate and Hybrid sleep are turned off.

If you are going to use a third party program, look at Wake Timers in the same section as you may have to enable these. Mine are disabled.

Look for a Dell Power Manager. If there is one and it is installed, uninstall it so it cannot conflict.
