The Dell Inspiron 5150 is a massive laptop computer weighing nearly 3.63 Kilogram and containing a full desktop Intel Pentium 4 processor rather than the low-power version typically found in laptops. The Inspiron 5150 has a slot for an optional internal wireless card, and if you have difficulty using the wireless card to connect to an access point, one of the initial troubleshooting steps to take is to make sure that the adaptor is turned on. The switch for the Inspiron 5150 wireless card is software-based and can be found in the Quickset utility pre-loaded on the computer.
