I received this HP NC6400 laptop off-lease from one of the Saskatchewan Crown corporations several years ago. The hard drive was removed so I installed a 320GB hard drive that I bought new in 2010. I have used it for some light testing and technical research but it is mostly in the same condition as when I received it. I have upgraded to something a bit newer which is why I'm selling. Specs/Features include: 2.5GB RAM Intel Core Duo T2400 / 1.83 GHz Wifi optical (DVD) writable drive 3 USB ports 1 ethernet port 1 serial port SD card reader The keyboard and touchpad are functional and in good shape. The power adapter is included and you'll need it; the battery doesn't hold much of a charge but replacement batteries are still available on the market if you're interested in using this as a mobile device. I installed CloudReady from Neverware on it. It is ChromeOS and it has basically turned the laptop into a Chromebook. This laptop is fine for casual web browsing, a user new to computers, or a hobbyist who likes to tinker and squeeze life out of older hardware. If you don't like this operating system, you can wipe it and install something else.
