Before retiring I worked in a large enterprise cubicle farm. Most users were givenDell Latitudes running Enterprise Windows, but there were some users who needed desktops with multiple large screens. The building was designed with power and thermal management to support 300 watts per cubicle. Circuit breakers were in a locked closet. People would add cooling fans, chargers for personal devices, and extra laptops (for visitors, field work or sanitized systems used for international travel) and trip a breaker, which cut power to a random collection of cubicles across 2 big rooms. We were told to log out but leave systems turned on so IT could install updates at night. In the morning they would be hibernating. -- George N. White III
