A: This is a more common fault. The CMOS circuit on the motherboard holds the relevant information of the BIOS setting, this circuit needs to have the weak current power supply to save the information, if the power supply is insufficient, will cause the information to lose, thus appears presses the F1 prompt when the power-on. First you check the motherboard for CMOS-powered button battery whether there is electricity, the battery for the ordinary CR2032 battery, the normal voltage of 3V, if less than 2.8V should be replaced. Replace the new battery after the problem is still, or soon appear prompt, then the motherboard on the relevant circuit problems (such as leakage), you can only replace the motherboard or repair. However, this fault usually does not have a large impact on the normal use of the machine, but also can not be ignored.
