Ben Guys, thanks for the info: Ben, sorry for not understanding where you were going with your first post. I did not realize that notebooks shared the same socket with desktops. I went to the following website and got the information. Y'all were correct about it being a mobile CPU. http://processorfinder.intel.com/details.aspx?sSpec=SL77N I thought I could possibly do something with Intel SpeedStep but I guess it is not available as a download. Mobile Intel® Pentium® 4 Processors - M 2.80 GHz sSpec Number: SL77N CPU Speed: 2.80 GHz PCG: Bus Speed: 533 MHz Bus/Core Ratio: 21 L2 Cache Size: 512 KB L2 Cache Speed: 2.8 GHz Package Type: 478 pin Manufacturing Technology: 0.13 micron Core Stepping: D1 CPUID String: 0F29 Thermal Design Power: 68.4W Thermal Specification: 100 DEG C VID Voltage Range: 1.3V

The laptops with Socket 478 Pentium 4 and Celeron CPUs looking exactly like the desktop ones did not last too long. Many of them suffered from thermal problems, because they drew so much wattage, as in the 68.4w CPU you have. Almost all of them showed up in the desktop replacements, with the Dell Inspiron 1100/1150/5100/5150/5160 and Latitude 100L being perhaps the most popular. You might download and try SpeedSwitch, then let us all know the results. http://www.diefer.de/speedswitchxp/ SpeedSwitch was designed to provide better control over laptop/notebook CPU speeds, but you never know. It may work with desktops, too. .... Ben Myers
