How do I tell that my raspberry pi 400 is switched on?

Hi all,

Is there a way for me to tell that my raspberry pi 400 is switched on?

I connect my pi to a LAN port and monitor my router logs for an IP address to be obtained. I plan to use this pi as a talking computer. I can do the same when I am at home but what about when I am traveling and in a first use scenario?

I am blind so cannot see any lights.

Hi and welcome to the list.

I too am fully blind, a mac user (professional / developer) and recently using the pi.

The Pi 400 like the pi boards themselves, is not easy to know if powered on or not until it boots to the chosen desktop OS and ORCA starts up. It's not like a PC where older systems the fans would ramp or there would be a system beep, or the mac, to this day, where it chimes.

Personally I believe that the pi should make use of a starting beep or some kind of chime from the specified output it finds on active boot.

Anything you try to do in that way won't start until the same point in booting as Orca starting. There is BIOS, there is no on-board beeper.

in that case, BIOS should give system beep as an option on power up. go back to the days of older intel systems, servers, etc where bios would use a system speaker to beep, this is part of POST.

There is no BIOS, there isn't a POST process. The Raspberry Pi does NOT boot that way.

For the sighted folks; all we see is the green LED winking and the scrolling kernel text if a TV is connected. You wouldn't be able to replace that LED with a beeper because it continues to wink after the system is fully booted.

It’s always a matter of footprint and cost with built in devices.
However the GPIO is available and addressable from both the boot firmware and the OS.
