Detection Level This function can be set to four levels. The sensitivity levels in which vibrations, impacts and their similar signs are detected can be set to OFF, 1, 2 and 3 in ascending order. Level 3 is recommended for better protection of the computer. However, when the computer is used in a mobile environment or in other unstable conditions, setting the detection level to 3 could result in frequent execution of HDD Protection, which will slow hard drive reading and writing. Set a lower detection level when the speed of hard drive reading and writing is a priority. Different detection levels can be set depending on whether the computer is used as handheld or mobile usages, or whether it is used in a stable environment such as on a table in the workplace or at home. By setting different detection levels for the computer depending on whether it runs with the AC power (desktop) or with batteries (handheld or mobile usage), the detection level automatically switches according to the power connection mode. User's Manual 4-52 Operating Basics Details To open the Details window, click the Setup Detail button in the TOSHIBA HDD Protection Properties window. Details Detection Level Amplification When the AC adaptor is disconnected or the lid is closed, HDD Detection assumes that the computer will be carried and sets the detection level to the maximum for 10 seconds. HDD Protection Message Specify whether to display a message when HDD Protection is active. This function does not work when the computer is starting, in standby, in hibernation, in transition to hibernation, recovering from hibernation, or powered off. Be sure to not subject the computer to vibration or impact while the function is disabled. This function only operates with Windows® XP. Heat dispersal To protect from overheating, the CPU has an internal temperature sensor. If the computer's internal temperature rises to a certain level, the cooling fan is turned on or the processing speed is lowered. You can select whether to control the CPU temperature by turning on the fan first, then if necessary, lowering the CPU speed. Or, by lowering the CPU speed first, then if necessary, turning on the fan. Use the Cooling Method item of the Basic Setup tab in TOSHIBA Power Saver. When the CPU temperature falls to a normal range, the fan is turned off and the CPU operation returns to standard speed. If the CPU temperature reaches an unacceptably high level with either setting, the system automatically shuts down to prevent damage. Data in memory will be lost.
