Hey everyone!

The suspend feature has never worked on my system, so I always turned it off in the settings. But now, with the electricity prices going up in my country (we have the most expensive electricity in Europe, lol), I figured it’s a good time to tackle this.

When the system tries to go into sleep mode, it just wakes up right away, and the monitors don’t show anything (no signal). I’ve got a backlit keyboard and an RGB mouse, but they don’t light up during this, and the caps lock key doesn’t respond when I press it.

I’m on kernel 6.12.7 and I updated the BIOS a few days ago, but the problem is still there.

My hardware:

• CPU: Ryzen 5 5600
• MOBO: GIGABYTE B550 GAMING X V2 (rev. 1.3)
• GPU: RX 6700 XT
• PSU: SilentiumPC Supremo M2 (600W I guess?)
• CASE: be quiet! Pure Base DX500

If anyone has any ideas on how to fix this, I would really appreciate your help!
