sleep troubleshooting

Sleep troubleshooting on Windows 10 and 11 involves diagnosing why a PC won't stay asleep, wakes immediately, or wakes randomly. Common causes include wake timers from scheduled tasks or updates, and devices like network adapters or mice that are allowed to wake the system. Windows includes built-in tools to identify the last wake event, list devices that can wake the PC, and check for active wake timers. This tag covers step-by-step methods to pinpoint and resolve sleep problems without third-party software, focusing on command-line and system settings. Topics include using powercfg to query wake sources, disabling wake timers, and adjusting device power management settings.
