I recently built a PC and I've run into a problem with the sleep function. When my computer goes to sleep, I can't wake it up using my keyboard or mouse; I always have to hit the power button. Is there any way to fix this?

Depending on your system, there might be an option in the BIOS that lets you select which USB devices can wake the computer. So if the settings in Device Manager don't resolve the issue, it might be worth checking your BIOS settings.
This is actually a feature that prevents your mouse from waking the PC accidentally if it detects tiny movements. You can adjust this in Device Manager by checking the properties of your input devices and allowing them to wake your computer.
Check in Device Manager for your keyboard and mouse. Right-click on each one, go to properties, then power management, and make sure to enable 'allow this device to wake the computer'. If that doesn't help, open CMD or PowerShell as an administrator and run 'powercfg -devicequery wake_armed' to see if your devices are recognized for waking. Then you can enable it with 'powercfg -deviceenablewake "Device Name Here".'
