	* Q: ~~what will~~ your UPS ~~do when the~~ power ~~will restored~~?		* Q1: How to do when your UPS cut off power suddently?
	A: ~~It will do nothing when~~ the power ~~is restored~~.		A:
	* Q: ~~How can I restart my Raspberry automatically? (without press~~ the power~~-on button)~~		1. Make sure you have connected the fixing borad into the circuit?
	A: ~~Sorry for that~~, it ~~has no~~ function ~~like that~~, ~~you need to press~~ the power~~-on button~~ to ~~start it~~.		2. Change the power supply and try again.
	* Q: ~~Your~~ UPS will ~~restart~~ the Raspberry ~~automatically?~~		3. Try to change the Batteries
	A: No, ~~It will~~ not ~~restart~~ the Raspberry ~~automatically unless you press~~ the ~~power-on button~~.
			* Q2: After more than ten hours or a few days of use, the UPS is powered off. When the charging cable is plugged in and unplugged, the battery level is only one bar. Or the battery level indicator keeps showing 4 bars, but the UPS is out of power.

			A: Because the original battery detection mechanism will sample the maximum capacity of the battery as a reference, in fact, most of the battery capacity is not up to the standard, so the IC is considered full when it is not fully charged. This is an inherent defect of the IC, and after the actual available capacity of the battery decreases. , The battery voltage did not drop, UPS could not perceive, so this problem occurred.

			Solution: Connect the mini fix board.The main function of this board is to force the charging IC to check the battery every 10 minutes and adjust the input voltage to be greater than or equal to 5V to ensure the reliability of the input power supply.

			* Q3: The repair board is connected or the power is off, and after the power is off, it is plugged in again to display 1 grid.

			A: This battery is too inferior. When the external power supply is connected to the UPS, there will be one path to power the Raspberry Pi and another path to charge the battery, and the path to charge the battery has not been fully charged. So this problem occurs

			Solution: Replacing the battery, especially those with obviously exaggerated capacity, must be fake. If you need to verify your battery capacity, you can use a simple method. First, do not connect the Raspberry Pi to charge the battery, and then connect the mobile phone or other mobile device through the USB port to charging the external device and observe that the charging capacity is roughly equal to your battery capacity.
