The option description:
By means of the given information option you can learn pressure of the battery feeding non-volatile memory (a CMOS-memory microcircuit) and the timer of real time. Rating value — 3 Century
This battery provides a course of hours and allows to keep options BIOS, the information on a hardware configuration even then when the computer is physically disconnected from an electric network. If pressure of a battery falls below threshold level (usually it occurs in 3—5 years of operation), it is necessary to replace it on new, differently after each deenergizing of the computer options BIOS will vanish and to get off system time.
At some realisations BIOS there is a colour allocation of the deduced information. If pressure within norm, you see dark blue figures if it left for admissible limits, colour of figures will be replaced with the red. It is quite often possible to refuse control of the given pressure in general. For this purpose it is enough to choose for an option value [Disabled] or [Ignore] (truth, the special sense in it is not present).
Be not surprised to constant "jumps" of displayed value — accuracy of schemes of measurement of the motherboard far from an ideal affects. To be convinced of it it is possible, having connected any normal measuring device (the voltmeter or an oscillograph).
