This laptop is about 7 years old, and was top of the line new with 1.86 GHz, 533 Mhz GSB processor, 1 MB L2 cache and 160 GB Hard Drive. The 15.4-inch screen is excellent: bright and crisp. The reason I'm selling so cheap is the OS is Win XP. Also has a CD/DVD drive. The hardware specs should allow upgrade to anything newer, including Windows 10.
