Look at the second photo.It has all the specs for the computer in it. After booting it up and taking these photos, I removed the hard disk drive so when you boot it up, it will not go to windows unless you install a new drive. Unit isn't overall very good condition. The unit does not include a power supply, a 65 watt one is recommended.

I have not tested the battery for longevity, It may need replacement, I don't know...
