HP Pavilion Laptop with 15.4 inch display, 160 GB drive, 3 GB RAM
It's worth noting that people have had problems with HP laptop computers. We've had 2 out of 3 of these die with bad motherboards. HP replaced them quickly and free of charge but we've also had problems with intermittent connectors on replacement power supplies (recommended by HP). On the plus side, HP does provide the Maintenance and Service Guide on line free of charge.

This is one place where the Apple MagSafe connectors beat traditional power connectors hands down. It can still be damaged but not as easy as the old barrel connectors which can easily be hit which damages the connection of the connector to the circuit board.
