Use Advanced Power Management (APM). Each operating system comes with its own power management. Stop the supply of power to the internal serial devices, including the modem, the serial port, and the infrared port, if they are not in use. Remove the battery pack and keep it in a cool place if you will not be using the computer for a long period. Ruggedized Mobile Computers Some professionals work in environments that may require special ruggedized features to protect their computers from extreme temperature, humidity, and physical punishment. Construction, public service, distribution, repair service, and utilities are some of the environmentally demanding professions that may require rugged mobile computers that can withstand stresses. For these applications, IBM offers such computers (not ThinkPad systems), especially designed for mobile professionals who need a system for managing and communicating information from the field. For more information on these computers, consult your IBM Business Partner. Ergonomics Information This is important information you should read before using your computer in your "virtual office." Working in the virtual office might mean adapting to frequent changes in your environment. Following some simple "rules of the road" will make things easier and bring you the maximum benefits of your computer. Keeping in mind such basics as good lighting and proper seating, for example, can go a long way in helping you enhance your performance and achieve greater comfort wherever you are. Appendix B.
