I accidentally found a button on the motherboard battery, I would like to ask, that battery can be used for how long?
If the motherboard battery is genuine goods but use less than a few months there is no electricity, that is, the voltage from 3.2V down to 2V or even 0V, then it is likely that the motherboard circuit leakage or diode breakdown short circuit caused by such failures.
Crystal to start the vibration and non-stop work must be power, or time to take the clock and the date will be inaccurate, we open the computer when the power supply to the crystal, when we shut down after the power from the battery to the crystal power supply.
Motherboard battery is to maintain the basic information on the board only the power supply, its role is to supply crystal, BIOS so that the data is not lost.
