Your data is stored on the hard drive, and that's just the motherboard battery.
The motherboard battery is responsible for memorizing the CMOS settings and the power of the clock function**, when the battery is dead, the CMOS settings and system time will repeatedly return to the factory preset because there is no memory effect. At this time, you only need to replace the battery on the motherboard, and when you accidentally change the password of the CMOS (BIOS) and cannot enter the settings, you can unplug the battery and wait for more than ten seconds to release the remaining power of the motherboard before putting it in.

Summary. Hello dear. 1. The output voltage is too low The input voltage of the circuit is too low, which will make the circuit abnormal, such as in the microcontroller system, the load suddenly increases, which will pull down the power supply voltage of the microcontroller and cause reset.
When the power supply works at a low input voltage for a long time, the life of the circuit will also be greatly affected. What are the common causes of low output voltage? l The input voltage is low or the power is insufficient; l The output line is too long or too thin, resulting in excessive line loss; lThe voltage drop of the anti-reverse diode at the input end is too large; l The input filter inductance is too large.
Dear, <>
The above is the answer I summarized for you, I am very happy to serve you, please give me a thumbs up, thank you very much for <>
I hope mine is helpful to you, and then I hope you are happy every day and have a good life<>
Good luck always comes with you, oh <>

Solution: 1) Turn up the voltage or switch to a higher power input power supply; 2) Adjust the wiring, increase the lack of large wire cross-section oak plum base product or shorten the length of the wire, and reduce the internal resistance; 3) Replace with a diode with a small on-voltage drop; 4) Reduce the filter inductance value or reduce the internal resistance of the inductor. Second, the input voltage is too high The input voltage is too high, it is very easy to burn the circuit, which brings greater harm, what are the common reasons that are easy to cause the voltage to be high?
l The output terminal is suspended or no load; l The load at the output end is too light, lighter than 10% of the rated load; l The input voltage is too high or the interference voltage is interfered with.
The reason why the accessories are called accessories is mainly because it has to be combined with other accessories to be able to play its due effect, the power module is the same, we have to install it after we buy it, so what problems do we need to pay attention to when installing the power module? Let's take a look! >>>More

In many cases, the automatic transmission is not damaged by the internal valve body, but by stubborn dirt and impurities inside, especially in the internal valve body, the dirty impurities accumulate to form a blockage, resulting in the inability to effectively adjust the oil pressure, resulting in the occurrence of the problem of stagnation, impact and slippage. At the same time, the problem of high temperature of the gearbox cannot be ignored. According to the Automatic Transmission Repair Association, it is called >>>More
