Abstract: This invention relates to a personal computer with a folding keyboard and, more particularly, to a personal computer contained within a compact enclosure when stored in a non-use position. The personal computer has a clamshell enclosure having first and second housings joined for pivotal movement one relative to the other about an elongate housing axis and between a folded position and a use position. Computer operating components are mounted in the enclosure. A keyboard assembly is operatively associated with the enclosure and the computer operating components and has first and second keyboard portions each bearing manually engageable elements for entering characters and commands. The portions are coupled together for pivotal movement one relative to the other about a keyboard axis perperdicular to the housing axis and coupled with the enclosure for sliding movement relative between a folded, stored position interposed between the housings and an opened, use position partially displaced from and overlying a side edge of the enclosure The keyboard assembly has, when folded about the keyboard axis, dimensions received wholly within the outline configuration of the enclosure.

Abstract: A computer has two processors. A main processor operates under the control of an operating system and provides overall control of the computer for executing application programs. The main processor also assists in power management by executing certain interrupts and controlling a power control register to turn power on and off to various devices. A power management processor monitors ambient temperature and humidity, and battery conditions, and generates interrupts as a result of predetermined changes. Such processor also controls charging of the battery. Logic means are responsive to predetermined conditions to also generate interrupts.

Abstract: A battery operated portable personal computer includes ambient temperature and humidity sensors, as well as two LCD's to provide visual indication that the ambient temperature or humidity is out of range. If the ambient temperature drops below 3 degrees C, or if it rises above 52 degrees C, the computer enters a low power suspend mode wherein the computer is inoperable, but, upon switching from the suspend mode to the resume (operating) mode, the application program that was running at the time of the suspension is resumed at the same point that the suspension occurred. The LCD temperature indicator is activated when the ambient temperature drops below 3 degrees C, or rises above 46 degrees C. Thus, for high temperatures, the temperature indicator is activated 6 degrees before the computer is placed in the suspend mode. The ambient temperature is periodically monitored while in the suspend mode and, if the temperature rises above 6 degrees C, or drops below 44 degrees C, the computer switches from suspend to resume. Thus, hysteresis is provided to prevent the computer from oscillating between suspend and resume modes. If the humidity rises above 96% relative humidity, the computer enters the suspend mode and the LCD humidity indicator is activated. The ambient humidity is periodically monitored in the suspend mode and, if it drops below 87% relative humidity, the computer switches from suspend to resume mode.
