Prime 2 Backup UPS

Hi everyone! I wanted to ask if anyone uses a UPS with their Prime 2 for backup purposes? I realize a benefit of the laptop is the internal battery takes over during the loss of AC preventing corrupt data and files from improper shut down. It would be very beneficial for the Prime 2 to have a built in UPS for situations when the power is accidentally lost. The user could then have time to properly shut down the unit and prevent damage, corrupt files ect. Any stand alone unit that could potentially be harmed by improper shut down should have this feature with a user replaceable lithium ion battery. I will be ordering an APC UPS for such situations that may occur. What are your thoughts?
