PC struggles to start from sleep and occasionally powers on by itself
You're experiencing an issue where your 64-bit Windows 10 desktop starts normally but displays a black screen after waking from sleep. The disk activity indicator appears briefly, then the screen remains dark, and sometimes the PC wakes itself on its own without a proper boot. You've already tried shutting it down frequently, which is frustrating since it disrupts your workflow and harms system stability.
Review your BIOS configuration to ensure the 'wake on' feature is correct or if a fast boot option is enabled, which could lead to issues. In Windows, examine your power preferences. Beyond that, what makes sense for you is staying awake all the time; it uses minimal power when idle. An SSD would address both the 'on/off' problem and improve speed.
If power consumption matters, power it down and then turn it back on. Opting for an SSD can significantly reduce the time needed, as it speeds up the operation considerably. This approach won’t damage the system more than regular use or keeping it idle; they’re designed to be switched on and off frequently. The most likely issue is a faulty power switch or button. If that’s the case, you can keep it running continuously 24/7 without problems, particularly if it’s in an idle mode. Even older components can operate 24/7 with extended idle periods for years, usually due to software or OS problems. This is quite typical in offices and other business environments.
Your machine is built to shut down automatically. Time isn’t a factor. Verify that Wake on LAN and Wake on Magic Packet are turned off in the UEFI/BIOS settings, and check the network options within Device Manager for your adapter (wired or wireless). Occasionally, the mouse might trigger wake-up due to vibrations or physical contact with the device—especially if it’s wired. It’s best to disable this function and ensure the system only responds to keyboard presses or power button activation. To prevent mouse activation, navigate to Device Manager > Mice and other pointing devices > double-click your mouse, then under "Power Management" adjust settings. Confirm all drivers are installed and up to date (including graphics card, audio, printer, motherboard chipset, SATA controller, etc.). If the PC still fails to awaken after a long sleep period, it may not support Windows’ hybrid sleep mode. This feature partially powers up the system during extended inactivity before entering hibernation and shutting down completely—ideal for laptops, but less efficient for desktops. For desktops, standard sleep is preferable and restarts work faster. To disable hybrid sleep: Open Power Options (Start menu), select Additional Power Options, change the plan settings to Balance (default), then modify advanced power settings. Expand "Sleep," select "Hibernate after," set it to "Never," and click OK. If issues continue, run Command Prompt or PowerShell as administrator, type `cd cd:\` and press Enter, then `powercfg /energy` to inspect sleep-related settings. This will help identify the root cause.
Omitte la mention dans les paramètres avancés des options d'alimentation : j'ai indiqué de configurer « Hiberner après » sur Non, et j'ai oublié de préciser que je devais aussi désactiver « Autoriser le sommeil hybride ».
