<p><b>New page</b></p><div>Hello, I am facing the same issue. Note that the undervoltage i am getting happens for 2 seconds and normalizes after/ is it similar at your end? <br />
Can you please share the code used for Input Voltage? <br />
<br />
<br />
<br />
From my end, I had configured a service to run and log the output of "top" command when undervoltage happens (I am monitoring dmesg). The Undervoltage happens when CPU total is above 100%, this is typically when RPi5 is launching an app or similar intense punctual calculation. Throteling the frequency to 1800 MHz (instead of 2400 MHz) in /boot/firmware/config.txt did not really help yet it made the reoccurrences of the issue become less. <br />
<br />
I got PSU_MAX_Current=5000 <br />
Attached Peripherals are: 1 wireless dongle for keyboard and mouse (issue used to happen also when I had cabled mouse and keyboard). Then screen through HDMI and a LAN cable. <br />
<br />
