System Stutter on Dell Laptop
If you're experiencing a system stutter every 20-30 seconds on your Dell system, try shutting down the Dell Wireless WLAN Tray Service in the Service Manager. I was having this issue with the brand new Latitude D830 I purchased. I first noticed it while listening to music with Windows Media Player, the songs would skip every 20 seconds or so. Moving the mouse around continuously revealed that this was affecting other system activity, as well. After shutting down nearly every app that was running on my system, I managed to make the issue go away as soon as I shut down the service I mentioned above. In the past, I have had issues with the Dell-provided software that has come pre-installed on their laptops. Dell, I'm sorry, you make great laptops but your software sucks. It has gotten to the point where, as soon as I receive a new system from Dell, the first thing I do is uninstall all of the Dell software. Hopefully, this fix will save you time and headaches. I suggest disabling the Dell Wireless WLAN Tray Service completely, it is not required. I did talk to Dell support and hopefully they will add this to their known issue list, or at least fix the service and provide a patch for their customers.
