==Overview==
'''[NOTE]''':  X728 supports also Raspberry Pi 5 hardware, the installation script is updated. Refer to [[X728-script]], If you have any problems with RPi5, please refer to [[#FAQ]]: Q1

QQ1: Why Raspberry Pi does the message "This power supply is randomly rebooting all the timenot capable of supplying 5A" appear on '''RPi 5'''??
</div>
<div class="mw-collapsible-content">
A: You [[X728]]/[[X729]] UPS shield can follow the steps to test if the X728 issue:provide '''enough 5A''' power supply capacity;
#Take the X728 off from the Raspberry Pi, remove all the batteries, power supply, and all jumper caps. Then connect the battery or power supply, press the blue power button on X728, the blue LED should be on, and then press and hold the power button for more than 8 seconds, the blue LED should be off.(These steps indicate that the X728 has no issue.)#Please check and confirm if other device occupy the GPIO with X728.#Still not find out the issue, please attach a video to contact us show more details.</div></div>set as follows:
Q'''Step 1''': Why (Required)Open the X728 V1.3 remove Teminal window based on '''Raspberry Pi OS''' and execute the ASD function?following command: sudo rpi-eeprom-config -eAdd <code>PSU_MAX_CURRENT=5000</code> at the end of the file that reads like this:
A[[File: Because the ASD jumper will generate some issues, so we remove the ASD jumper, but now you can achieve ASD function by software. Read the voltage through I2C, and then decide whether to shut downX1012-setting.png|700px]]
Press '''Ctrl-O''', then enter, to write the change to the file.
Q1: Why X728 V1Press '''Ctrl-X''' to exit nano (the editor).2 automatically shuts down?
A'''Step 2''': 1. X728 V1.2 will automatic safe shutdown when battery voltage is low than 3.0V(Optional, please charge in time;if you use USB peripherals and require higher current)
2Set <code>usb_max_current_enable=1</code> in '''/boot/firmware/config. Please try the following operation by step:# Remove all jumper cap, # Remove all 18650 battery # Place 18650 battery again and wait a few seconds before testingtxt'''
3'''Reboot''' your Raspberry Pi 5 to make the change take effect. What battery is recommended for X728?
A'''Note:Because there ''' If you are so many kind of batteriesusing other OS like Ubuntu, and the quality is also various. So we suggest to use the NCR18650B from Panasonic. Also please flash '''do not useRaspberry Pi OS''' 18650 battery with builtfirst, and then re-in protection circuit for X728flash other OS such as Ubuntu etc after completing the above settings.</div></div>

Q: Why the X728 V1.3 remove the ASD function?
</div>
<div class="mw-collapsible-content">
A: Because the ASD jumper will generate some issues, so we remove the ASD jumper, but now you can achieve ASD function by software. Read the voltage through I2C, and then decide whether to shut down.

Q3<div class="toccolours mw-collapsible mw-collapsed"><div style="font-weight:bold;line-height:1.0;">Q: How to restart the pi board when AC Power supply is connected?</div><div class="mw-collapsible-content">
A: Please enable 'AUTO POWER ON' or 'AUTO ON' function if you want restart when the AC Power supply is reapplied.
</div>
</div>
<div class="toccolours mw-collapsible mw-collapsed">Q4: About auto shutdown, found your board auto shutdown. A: Please check if enable the ASD function (shorted the ASD header), if you enable the ASD function, please make sure your operation is right: first, place the battery into the battery holder, insert the jumper to ASD header <span div style="colorfont-weight:redbold;line-height:1.0;">after 3 seconds</span>,this is very important!!  Q5:Is the recharge threshold and terminal battery voltage adjustable? I want to keep the batteries between 80% and 20% A: Sorry, this is not support.   Q6Q: Which GPIO is used to power the X728-A1 cooling fan?</div><div class="mw-collapsible-content">
A: The X728-A1 does not occupy the GPIO, it use the PIN 2,4 to provide the power.
</div>

<div class="toccolours mw-collapsible mw-collapsed">
<div style="font-weight:bold;line-height:1.0;">
Q: Are the batteries on X728 hot-swappable? In other words, can I connect an external power supply and swap the batteries out while that is on?
</div>
<div class="mw-collapsible-content">
A: Sorry, the batteries on X728 is not support hot-swappable. Please cut off the power to swap the batteries.
</div>
</div>
Q7<div class="toccolours mw-collapsible mw-collapsed"><div style="font-weight: How can I remove all software created by the setup and start over? Abold;line-height:1) sudo /etc/rc.local , delete x728pwr.sh 2) sudo rm /etc/x728pwr.sh 3) sudo rm /usr/local/bin/x728softsd.sh  Q8: What are GPIO5 and GPIO12 used for X728 V1.3/V2.0? A: GPIO5 control shutdown, GPIO12 boot.  Q9: Are the batteries on X728 hot-swappable? In other words, can I connect an external power supply and swap the batteries out while that is on? A:Sorry, the batteries on X728 is not support hot-swappable. Please cut off the power to swap the batteries.;">  Q10Q: Does the rtc have a separate battery? or does it run on the 18650 batteries? what happens if you remove them? will it "lose" time?</div><div class="mw-collapsible-content">A:No, the RTC function runs on the 18650 batteries. It will "lose" time if you remove the batteries.  <span style="color:red;font-weight:bold"/div>Q11: What will lead to the X728 board be burnt out?</spandiv>

Q: What will lead to the X728 board be burnt out?
</div>
<div class="mw-collapsible-content">
A: Please make sure the polarity of battery is "+" to "+" and "-" to "-" and match with the "+" "-" mark on battery holder. The battery protection chip IC will be over-current, heat and then burnt if one or two of the batteries are connected reversely. PS: the X728 board will not be burnt immediately if one or two of the batteries are connected reversely.
