Power Management
Because the GSA Unit is a sophisticated system with multiple potential power sources and several
When external power, either A/C or D/C, is available, that should be the preferred operating mode since it will generally provide the longest uninterrupted operation. One of the best techniques when external power is not available is to take advantage of the power management features of the laptop computer. Place the CPU switch in the off position. This cuts off case battery power to the laptop forcing it to run on its own battery, while still providing power to the peripheral components. When the batteries in the computer become low with use, the CPU switch can be placed back in the on position until the computer batteries have been restored.
After a couple of hours on case battery power, the GSA Unit internal batteries are no longer able to fully charge the computer batteries and/or provide power to the peripherals. At this point, the GSA Unit should be connected to external power or data should be saved to disk and preparations made to power down the system.
The GSA Unit peripherals can consume quite a bit of power, even when just idling. Therefore, if you anticipate operating for an extended period on the batteries, turn off any peripherals you are not using.
