Fixing Windows computers that won't wake from sleep
If your Windows computer won't wake from sleep, there are several fixes you can try. Firstly, check that your keyboard or mouse has not been prevented from waking the computer. This can be done by going to the Start Menu, clicking "Power Options", "Choose what the power buttons do", "Change settings that are currently unavailable", and ensuring that the "Turn on fast startup" checkbox is cleared. If this does not work, you can try updating all your drivers to the correct, latest version. This can be done through Driver Easy, which will automatically download and install the correct versions.
If the above methods do not work, you can try updating your BIOS and chipset driver. To do this, go to the Dell website and download the Dell OS Recovery Image. Before flashing the BIOS, ensure that BitLocker is suspended, or your computer will not recognize the BitLocker key upon reboot.
Another fix is to enable USB Wake Support. To do this, open Device Manager, locate and expand "Network adapters", right-click your network adapter, select "Properties", navigate to the "Power Management" tab, and check the box to "Enable USB Wake Support".
If your laptop is completely unresponsive, you may need to force a hard shutdown by holding down the power button for 10-15 seconds. This will cause any unsaved work or data to be lost. Once the computer restarts, check for any error messages or unusual behaviour.
