Resolve sleep problems

Whether your computer won’t stay asleep or won’t wake up, these simple steps can help

Does your PC have trouble sleeping? The sleep mode in Windows 8 is handy, as it enables you to effectively 'pause' your computer, rather than shutting it down (your computer springs back to action at the click of a mouse or tap of the keyboard, with your programs open just as you left them). However, it's a feature that's not immune to the odd glitch.

If you're having trouble with the sleep mode on your Windows 8 PC, you'll most likely find your computer either keeps waking up from sleep or can’t be roused at all. Here, we'll take a look at the common fixes that should solve sleep issues.

1. My mouse or keyboard won't wake up my PC

If your sleeping PC won't respond to mouse clicks or the rattling of keys, you need to make sure those peripherals are enabled to wake it up. To do this, open Device Manager. Press the [Win] + [X] keys to open the Quick Access menu, and select Device Manager from the list.


2. Change the settings

In Device Manager, click the > button next to Keyboards or Mouse and other pointing devices to expand it. Now right-click your keyboard or mouse and choose Properties. Switch to the Power Management tab and make sure the box next to ‘Allow this device to wake the computer' is ticked. If you don't see the Power Management tab, click the Change Settings button. The same Properties box will open with the Power Management tab visible.


3. My PC wakes too easily

You may be having the opposite problem and finding that a USB device is waking up your PC when you don't want it to. If that's the case, follow steps one and two, then untick the 'Allow this device to wake the computer' box.

If that doesn’t resolve the problem, it’s more likely to be another hardware device that’s responsible: re-tick the box(es) and expand Network Adapters in Device Manager instead. Right-click whichever network adapter you use to connect to your network and internet (either Wireless or Ethernet Controller) and choose Properties. If there’s a Power Management tab, select it and untick 'Allow this device to wake the computer' – if it’s not greyed out – then click OK to prevent it from waking your PC.


4. Unplug everything

If the above steps don't help your sleep -deprived PC, a simple way to isolate the problem is to unplug all non-essential USB devices from your computer. Once all the peripherals are unplugged, check to ensure your computer will now stay in sleep mode. Now plug in those items one by one, checking each time to see if your PC stays in sleep mode, until you find the one that's causing the issue. Check its Device Manager settings to see if there’s a Power Management tab where you can prevent it from waking your PC.


5. Are you using a screensaver?

Lots of people still use screensavers on their computer but these sometimes cause problems when waking up your PC. Try disabling yours to see whether that helps. To do this, right click on the desktop then choose Personalize. Now click on the Screen Saver option and, in the box that opens, choose None from the dropdown menu.


6. My PC goes to sleep by itself

If your PC goes to sleep unexpectedly, check the power options first. Press [Win] + [X] and select Power Options. Choose a plan setting or click Change when the computer sleeps to make sure Windows is set to sleep at a time that suits you, not the other way around.
