- Preconditions: |
- 1) Device under test (DUT) is connected to the LAN via an |
- Ethernet-to-USB adapter plugged into one of its USB ports. |
- 2) AC power cable is connected to the DUT, and plugged into |
- the IP controlled Power Switch, outlet #4, located in the lab. |
- 3) Battery is installed in the DUT, and battery is not fully |
- discharged. |
- 4) Tester should have physical access to the power switch. |
- |
- Note about time calculation: |
- When AC power is turned off or on, the battery will take from 2 |
- to 60 seconds to calculate the time remaining to empty or full. |
- While calculating, the keys 'battery_time_to_full' and |
- 'battery_time_to_empty' are absent. |
