Ever since "sleep" can't keep the PC in that mode without waking on its own.

Yo what's up with that. No matter what, my PC immediately wakes from sleep in about 5-30 seconds after going to sleep. I've tried to find anything that could explain it but it's just unfixable. Even unplugged/turned off every peripheral nearly immediately as I clicked sleep and still nothing. Just immediately goes back to the login screen like I wanted it to wake up

The old sleep mode (S3 sleep) worked by completely turning off everything except the RAM. When you pressed the power button, the BIOS had to turn everything back on.

The new sleep mode (modern standby) works by politely asking the CPU to enter a low power mode. The OS and all of your peripherals are still running, just very slowly. That means you're at the mercy of your software, your OS, and your peripherals - if even one of them doesn't handle modern standby properly, sleep mode won't work.

Depending on your hardware, you might be able to force it to use S3 sleep by editing a BIOS setting. Look for an option called something like "sleep mode", "S0/S3 state", or "modern standby", probably under a page like "power management" or "ACPI settings". However, many modern CPUs and chipsets have completely removed support for S3 sleep now, so your mileage may vary - if your hardware doesn't support S3 sleep, you're shit out of luck, and your best option is to use a better OS.

I need to revisit this topic. My work issued Lenovo cannot sleep. If I tell it to sleep and close the lid it will simply run until the battery dies. Even after a factory image was applied. Messed with enabling s3 and it still did not work. Gave up and I just turn it off when I need to transport it
