All have been turned on and go as far as the second listing photo above which. I believe since there is no hard drive that it will not go past that. All come with power adapter that we used to start the monitor up.
All are in similar condition if not better. We are not responsible for incompatibility issues. We truly value the opportunity to work with you and provide service and support.
We do guarantee this to be in working condition. We do not guarantee batteries. We guarantee 30-DAY NO DOA!
