Will the data be lost if I replace the power module?

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.

Hello. eeeccc0606

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.

How to deal with damaged power modules.

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.
