Inspiron XPS

The first XPS laptop, which was a rebranded Inspiron 9100, was a very heavy desktop-replacement laptop starting at 9.06 pounds without power supply (which added an additional 2.5 pounds). This was because it was offered with either a 3.4 GHz desktop Pentium 4 HT "Prescott" processor, or the 3.4 GHz "Gallatin" Pentium 4 Extreme Edition processor at the same clock speed, which gave off tremendous amounts of heat due to their high clock speeds and inefficient microarchitecture, despite a very large copper-based heatsink that spanned the width of the unit with three fans. Other features included a 1920 × 1200 15.4-inch LCD, and subwoofer integrated into the bottom of the battery casing. Earlier models came with an ATI Mobility Radeon 9700 with 128MB of memory, and later models with the Mobility Radeon 9800 with 256MB of memory. Dell promised graphics card upgradability, but only delivered the small 9700 to 9800 step for 9700 owners (at a rather steep $399 price tag, including technician to install it), and never delivered the promised upgrade to the 9800 owners. This model also suffers from an annoying whine on the headphone and microphone jacks that are located on the left of the unit. This is because of shared space with the leftmost fan, and the spinning of said fan causes interference. There is no known fix than to otherwise use a USB or PCMCIA-based audio device or card for sound output.
