Compliment your Dell C640 notebook computers with a wireless mouse and keyboard

When you aren't on the road with your Dell C640 laptop, you'll probably find it more comfortable to use a mouse and full-size keyboard. Wireless mouse/keyboard combos are inexpensive and hold down clutter. Typically, you'll plug into a USB slot a receiver, which works with both the mouse and keyboard. The accessories communicate via radio frequency, allowing non-line-of-sight communication.

I recommend: IOGEAR Inc. sells a mouse/keyboard combo with a charging base station for the mouse. Logitech offers many high quality combos, such as the Cordless Desktop Wave.

Expand your Dell C640 laptop with larger-capacity hard drives

Standard Dell C640-009 laptops come with 20 GB hard drives. This is enough room for most document storage and processing needs. But if you want to store many songs, videos or large graphic files, you'll need a hard drive with greater capacity. You can easily replace the included hard drive with a standard internal laptop hard drive.

I recommend: Priority Electronics, Inc. sells internal laptop hard drives with capacities into the hundreds of gigabytes. Choose from among dozens of fast (7200 rpm) laptop hard drives at Super Warehouse.

Add an external DVD-RW to model 009 Dell C640 notebooks

The Dell Latitude C640 laptop comes with a CD-RW but not a DVD player. You may want to watch a movie or record your own. A USB-connected DVD burner is an inexpensive addition.

I recommend: Check out the IDVD8PE from I/OMagic Corporation. This USB 2.0 DVD rewritable external drive stores up to 8.5 GB on dual-layer DVDs. The Kanguru QS2 DVDRW from Kanguru Solutions can burn custom labels onto LightScribe compatible CDs or DVDs. LightScribe labels are not stuck to the surface of the media, but are an integral part of the disc's surface.
