Many users who are using Laptops from different manufacturers are facing issues of either laptop won’t go to sleep, if it does then Power still remain ON and even they’ll find that CPU and fan are working as well. But there won’t be anything on the screen and you’ll not be able to wake it back from sleep. Not just laptops, even hybrid of Laptop and Tablet i.e. Surface Pro users are also facing similar issues, that only screen turn off, but board light, fan etch would be still working and also Surface Pro getting hot sometimes during sleep mode. These situation, users never faced before in “Windows 8.1”. Show Users who’re facing this issue have laptops of:
Usual issues are:
With this list, it is clear that if somewhere drivers from manufacturers could be faulty, majority of users are facing this issue because of upgrade to Windows 10. Solution 1
If this doesn’t fix the issue, then here’s another solution: Solution 2 Rather than just updating the driver from windows update, let’s update the driver and force it to use driver files from previous windows installation where you didn’t had the issues i stated above.
This should fix the wake up from sleep issue. However please note that this solution shall work only if you have upgraded to “Windows 10” and you’ve not deleted previous Windows installation folder i.e. “windows.old” folder, because computer shall gonna search for driver in this folder too for display driver. Solution 3 If above solution proves to be temporary solution, then assuming you’ve already did steps of Solution 2. Then:
Although doing this solution doesn’t make any sense really, but many users have been able to get the issue fixed this way. So it’s worth a try. Solution 4 For fixing wake up issue, you need to follow these steps and try to run the Power troubleshooter:
Also try to run the “System maintenance troubleshooter” from “Troubleshooting” lists after running “Power Troubleshooter“. Also turn off “Fast Restart” in the power settings. Although this solution has less chances for fixing wake up issues, still you can give it a try.
When my monitor began refusing to wake up from sleep mode, I started researching the issue and quickly discovered that I’m not alone in my troubles. In fact, by my completely unscientific estimates, it seems that everyone has suffered from this at one point or another. Unfortunately, there is no universal cause for this, so there’s no universal solution. However, seeing as there are several possible ways to resolve this, I’m going to run through some of the most popular causes and solutions to this age-old issue. Disable Deep Sleep (Dell Monitors)Dell monitors (and maybe others) have a special feature called Deep Sleep, which lowers the power usage of your monitor even more than going into regular standby mode. It’s somewhere between outright unplugging in your monitor and just having it in standby. In most cases, it’s not a very useful feature and can mean that if your monitor goes to sleep with your PC, then your monitor won’t automatically turn on again when your PC comes out of sleep. This means you have to manually turn on your monitor when Deep Sleep is enabled. You can do that or just disable Deep Sleep on the monitor. To do this, turn on the On-Screen Display on your monitor, select “Others -> Monitor Deep Sleep,” then disable it there. Note that other monitor brands might also have this feature, so take a look in your monitor settings to see if you have it, then disable it if you like. Disable PLL Overvoltage (ASUS Motherboards)Asus deals with a lot of motherboards, and for the most part, they deal with them quite well, but there are a couple of quirks on them that can cause things to go a little bit wrong. For example, most modern-ish Asus boards have a feature called “PLL Overvoltage” enabled by default. This helps overclock your CPU that little bit more, so if you’re worried about eking out those extra few-hundred MHz out of your rig, you may want to leave it on. But if getting your PC some sleep is a priority, then you may need to turn this feature off, and to do that, you need to go into the dreaded BIOS. Reboot your PC, then as it’s booting, press the Delete key until the BIOS screen appears. Things may vary a bit here from one motherboard to another, but to find the option, go into the “Advanced Mode” (the F7 key on my Asus Z97 MOBO). Next, select “AI Tweaker” from the options at the top of the screen, then click the drop-down next to “Internal PLL Overvoltage” and change it to OFF. Save the settings and exit the BIOS. Disable Link State Power ManagementSometimes those seemingly helpful power options in Windows can prove to be a liability, accidentally keeping certain things in a dormant state, even when they’re definitely meant to be on. Here’s how to make sure power management doesn’t interfere with your monitor. Go to “Control Panel -> Power Options,” then select “Change plan settings,” for the power plan you’re currently using, and “Change advanced power settings.” Next, scroll down to “PCI Express,” click the “+” icon next to it, and under “Link State Power Management,” change the setting to “Off” and click “Save changes.” Disable Auto-Detect in Monitor SettingsA seemingly simple option but a good one. When your monitor goes to sleep, the connection between it and the cable connecting it is severed. For some silly reason, however, when the connection gets re-established (when you bring your monitor out of Sleep mode), sometimes the monitor doesn’t re-establish that connection, even though the cable is still plugged in. A possible solution to this is to use the buttons on your monitor to switch off the “auto-detect” option. One of these solutions should solve your woes with reawakening your monitor.
