Q<div class="toccolours mw-collapsible mw-collapsed"><div style="font-weight:bold;line-height:1.0;">Q1: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">[[X728]]/[[X729]] UPS shield can provide '''enough 5A''' power supply capacity;
A:You can follow the steps to test if the X728 issuePlease set as follows:
a'''Step 1''':Take the X728 off from (Required)Open the Teminal window based on '''Raspberry Pi, remove all the batteries, power supply, OS''' and all jumper caps. Then connect execute the battery or power supply, press the blue power button on X728, the blue LED should be on, and then press and hold following command: sudo rpi-eeprom-config -eAdd <code>PSU_MAX_CURRENT=5000</code> at the power button for more than 8 seconds, end of the blue LED should be off.(These steps indicate file that the X728 has no issue.)reads like this:
b[[File:Please check and confirm if other device occupy the GPIO with X728X1012-setting.png|700px]]
c:Still not find out Press '''Ctrl-O''', then enter, to write the issue, please attach a video change to contact us show more detailsthe file.
Press '''Ctrl-X''' to exit nano (the editor).
Q'''Step 2''': Why the X728 V1.3 remove the ASD function?(Optional, if you use USB peripherals and require higher current)
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 downSet <code>usb_max_current_enable=1</code> in '''/boot/firmware/config.txt'''
'''Reboot''' your Raspberry Pi 5 to make the change take effect.
Q1'''Note: Why X728 V1''' If you are using other OS like Ubuntu, please flash '''Raspberry Pi OS''' first, and then re-flash other OS such as Ubuntu etc after completing the above settings.2 automatically shuts down?</div></div>
<div class="toccolours mw-collapsible mw-collapsed"><div style="font-weight:bold;line-height:1.0;">Q: Why Raspberry Pi is randomly rebooting all the time?</div><div class="mw-collapsible-content">A: You can follow the steps to test if the X728 issue: 1. #Take the X728 V1off from the Raspberry Pi, remove all the batteries, power supply, and all jumper caps.2 will automatic safe shutdown when Then connect the battery voltage is low 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 38 seconds, the blue LED should be off.0V(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 charge in time;attach a video to contact us show more details.</div></div>
2<div class="toccolours mw-collapsible mw-collapsed"><div style="font-weight:bold;line-height:1. Please try 0;">Q: Why the following operation by step:# Remove all jumper cap, # Remove all 18650 battery # Place 18650 battery again and wait a few seconds before testing X728 V1.3. What battery is recommended for X728remove the ASD function?</div><div class="mw-collapsible-content">A:Because there are the ASD jumper will generate some issues, so many kind of batterieswe remove the ASD jumper, but now you can achieve ASD function by software. Read the voltage through I2C, and the quality is also various. So we suggest then decide whether to use the NCR18650B from Panasonic. Also '''do not use''' 18650 battery with built-in protection circuit for X728shut down. </div></prediv>  Q3: How to restart the pi board when AC Power supply is connected?

<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>
<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 BOOK OK.  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>
<div class="toccolours mw-collapsible mw-collapsed">
<div style="font-weight:bold;line-height:1.0;">
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.
