The problem of with the service life.
The CR2032 button electricity that the battery that cmos data preserves all is a standard is controlled above X86 platform motherboards at present
Pond, in the case where mainboard powers off, hardware circuit automatically switches to button cell power supply, and button cell be not to keep CMOS numbers
In the case of according to power supply, and there is leakage loss, so battery life is tapered dosage, battery will be encountered in use
The process of replacement.Present battery altering is that all electricity are all broken, and then button cell is taken away, replaces a new electricity
Pond.The data being arranged under BIOS in this process will lose, and all settings all restore default setting, if user want it is extensive
Multiple legacy data then needs to reset data, very inconvenient for many clients to being changed under BIOS.And battery electricity
The unspecial voltage monitoring of amount just knows dead battery when only user has found the loss of data being arranged under BIOS.
Also have increase reserve battery, as replace button cell when, to mainboard temporary power use, but the program there are battery wave
Take, cost increase the drawbacks of because the service life of a button cell, about in 2 years, user replaces one-shot battery
Period is also very long, and it is more wasteful resource that individual one piece of battery, which uses when being replacement battery as reserve battery,.

When electric, super capacitor can prevent loss of data directly to PCA9555 chip power supplies；Super capacitor is connected by switch two and is indicated
Lamp, when detecting memory failure, closure switch two, when not detecting, switch two is in the open state, avoids wasting；
3., super capacitor to the PSOC chip power supplies on mainboard, PSOC chips are a digital oscilloscope work(on mainboard
Can chip, the height variation of the level of each sequential when can be with capture switch machine, PSOC chips can be capturing
Timing variations before time series data is write in RAM card, but PSOC chips cannot capture the electricity itself connected are electric with itself
Timing variations after falling, because also having sub-fraction sequential to exist before and after the electricity of PSOC chips normal work, in this way
It there is sequential and monitor incomplete disadvantage, the disadvantage can be made up to PSOC chips temporary power using super capacitor, moreover it is possible to
It is enough that PSOC temporary powers are given in the case of mainboard accident power-off, obtain the timing variations under fortuitous event；
（Three）, the utility model supplied by the interim substituting battery of large capacity super capacitor of a 3v to mainboard temporarily
Electricity realizes super multi-purpose content, while solving the problems, such as environmental pollution and the old and useless battery recycling of battery；
（Four）, super capacitor rear end connect diode, super capacitor temporary power is automatically switched to after battery is taken away,
Battery powered is switched to after on battery altering, super capacitor can ensure the normal work in the main board system short time；
（Five）, button cell positive output end connect A/D chip, the sense terminal of A/D chip connects BIOS, for detecting voltage
Data, BIOS is notified that user when battery capacity is too low, and user presses lower switch one, replaces battery, based on super capacitor
RTC power supplys on plate keep setting data under BIOS not lose.
