TECRA M4 4-45
Operating Basics
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 as
handheld or in other unstable conditions, setting the detection level to 3
could result in frequent execution of HDD Protection, which will slow HDD
reading and writing. Set a lower detection level when the speed of HDD
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. Furthermore, the detection level can be individually set
also during use in Tablet mode (Battery).
