Dell's Latitude E4300 laptop is primarily designed for business customers. The E4300 has an Intel Core 2 Duo 2.4 GHz processor, 4 MB of system memory and a 13.3-inch display. The Basic Input/Output System (BIOS), which is on every computer, is special firmware that allows you to tweak hardware and system settings. If your E4300 isn't running properly and you need to reset BIOS to remedy it, enter the BIOS menu and load factory defaults.
