I purchased the CANAKIT Raspberry pi with the Canakit power supply. I purchased the pre-loaded microsd card. On first power up I got the rainbow and the lightning bolt (no menu) I've tried 3 alternate power supplies and plugging the usb cable into my computer USB port. No change!

- sounds like a bad power supply .... your computer's usb port has its output current limited to 500mA by design, therefore it does not have the capacity to power an RPijsotola– jsotola2018-05-20 03:52:53 +00:00Commented May 20, 2018 at 3:52
- If you have a multimeter handy, try checking the voltage across the Pi to see if the power supply is within range. Also, perhaps edit your question to include what version of Pi you have, and what rating your power supply has (it will probably have voltage/current ratings on the plug itself).Aurora0001– Aurora00012018-05-20 09:20:45 +00:00Commented May 20, 2018 at 9:20
- Does this answer your question? What does the lightning bolt mean?null_override– null_override2020-09-20 10:45:30 +00:00Commented Sep 20, 2020 at 10:45
