Windows 10: Why does my win 11 pc monitor says no signal while the keyboard doesn't light up either?

Hi all, I'm operating on Win 11. Lately my monitor says no signal when I started up. I also noticed my keyboard doesnt light up as well. Therefore no input or notification is available. The battery indicator externally next to the power button indicator is absent as well. The led fans color is dulling or fading too.Do I take that as a need for a change of battery?My monitor is hdmi connected to both my ps3 + ps4. They both connect well with the monitor and work.Lately sometimes, my keyboard would not light up and I would have to reconnect the cable to have it work. There was a display on the m

PC boots up but monitor shows 'no signal' and keyboard not working.

My W10 PC boots up, fan spins, HDD spins but there is no output to monitor, which shows 'no signal' and the keyboard does not light up. I have tried all the suggested diagnostics such as unplug power, take out the CMOS battery, re-seat the RAM, clean RAM etc but nothing. It did come back on a few weeks ago for a few days then reverted to display showing 'no signal'. Any suggestions how to get this PC to display and work again are welcome.

Many posts i have read suggest entering BIOS etc or settings - i cannot do this as no display!

Please suggest fixes for my situation as above.

Thanks

 

Night Light Setting and Third Monitor.

Hi Reagan,

We would like to ask you some questions in order assist you properly:

• Did Night light work previously on all three monitors?
• Have you made any recent changes to your PC?
• Are you getting an error message on the third monitor regarding Night light?
• Is the third monitor being detected by your PC?
• What troubleshooting steps have you performed so far?

While waiting for your response, we suggest that you try to connect your third monitor to what you are using on the 2 working monitors to see if it is only a loose connection issue.

Regards.
