Raspberry Pi Lightning Bolt – What Does it Mean? | How to Disable it?

Today, I will explain about the lightning bolt on Raspberry Pi. What this term means and how it can affect the performance of the Pi. How you can disable Raspbian lightning bolt. We will see all these here.

What is the Raspberry Pi Lightning Bolt?

The Raspberry Pi lightning bolt is an error that causes in the Raspberry Pi PC. It appears at the top right corner of the Raspberry Pi display. It looks like small red or yellow squares in the past. In modern Raspberry Pi systems (News: Raspberry Pi 3 Model B+ is on Sale Now!), this symbol has changed to make the user aware more precisely about the situation.

When the Raspberry Pi Lightning Bolt error appears, that means your system is either facing the under-voltage or over-temperature issue.

How to solve Raspberry Pi Lightning Bolt Error?

So, we know now that the lightning bolt on Raspberry Pi is an under voltage warning that appears on the Pi monitor. Let’s have a look to solve this issue on Raspberry Pi 3 (I just love this SBC).

Solution-1: Disable Raspberry Pi 3 Lightning Bolt

Though this method is not recommended to do, follow the steps below if you want to ignore the warning.

1. Open the command line editor in your Raspbian Stretch OS

2. Enter the command below to open the configuration file

   sudo nano /boot/config.txt

3. Write the below text line in the configuration file


4. Save the file

5. Reboot Raspberry Pi device

After doing this, you will not see the under-voltage warning on your Raspberry Pi screen. If you want to make it be displayed again, remove the above text line, save the configuration file and reboot the Pi.

Solution-2: Make changes with the Power Supply

As you know, the Raspberry Pi 3 is the fastest Pi board, and also it takes more power than any other Pi member. The newly introduced Raspberry Pi 3 Model B+ consumes even a little bit more power than that. So, another good option to fix the under-voltage or overheating error on PI is to use a proper power supply.

Get a sufficient 5V 2A charger for your Raspberry Pi (the Pi 3 Model B+ needs a 2.5A power supply). You can also try to change the power cable if it’s not appropriate or if it is older. Sometimes, changing the power cord also do the work of providing sufficient input to your Pi setup.
