6.5 Pounds

As far as I can tell, this unit is fully functional and runs great. It has Windows XP Home, Office 2007 Professional, and Adobe Acrobat 9 Standard. Includes original Dell power adapter. Battery does work, you can see it booted up on battery in the images. I have not tested the runtime other than the level did not seem to drop from turning it on, taking some pictures, and turning it back off. Since the battery is used there is no warranty of any kind on how long it will run/last.
