Windows 10 updates are hard to avoid as Microsoft continues to push the latest version of its OS. It works fine for most people, but if you are having power problems and sleep mode issues afterwards, try these fixes.
Windows 10 updates have been coming at a rate of two a year, one around April and one around October. Some people have found that after installing one of 10’s big updates, there are power issues, such as the computer not entering sleep mode or problems after waking from sleep mode. What can you do?
(Note: All the advice here applies to Windows 7 and 8 too. The menus might be different, but the solution is basically the same.)
Check for updates
Firstly, press Windows +I to open Settings and click Update & security. Click Check for updates. Windows should check automatically, but it is worth forcing a check. The next update might contain a fix for the power issues you are having.
Run a troubleshooter
There are a number of troubleshooters in Windows and these can sometimes fix problems. Microsoft is slowly moving Control Panel items to the Settings app and troubleshooters can be accessed from Settings > Update & Security > Troubleshoot. However, they are still in the Control Panel too.
Click the Start button, expand Windows System on the menu and click Control Panel in the menu that is displayed. Set View by to Small icons and then click Troubleshooting.
A few troubleshooters are listed, but there are many more that are not immediately visible. Click the View all link on the left.
Find the Power troubleshooter in the list and click it to run it.
When the Power troubleshooter runs there isn’t much to do except click the Next button. It might take a minute or two to finish. Just follow any instructions that are displayed.
Check the power plan
There are different power plans for Windows and this allows you to optimise it for different usage scenarios. For example, you might want to run a laptop at full power when it is plugged into the main supply, but to reduce the power usage when running on batteries to enable it to last longer.
Left click the battery or power icon at the right side of the taskbar and there is a Power Mode slider. Try different positions, such as the far left or right and see if it makes a difference.
Right click the battery/power icon and select Power options in the menu that is displayed.
The Control Panel opens and shows the power plans. Whichever power plan is selected, click Change plan settings.
On the next screen down near the bottom on the left is Restore default settings for this plan. Click it.
Windows updates can delete power plans from Power Options the Control Panel, but they can be brought back. Click the Create a power plan link on the left.
Update the drivers
Power and sleep problems can be caused by faulty or incompatible hardware drivers. Updating them might cure the issues you are having. Right click the Start button and select Device Manager in the menu.
Left click a category and then right click an item and select Update Driver Software.
It would be tedious to check all items in all categories all for updates, so you can try going straight to the most likely causes of the problem. Right click each of the Batteries entries and select Update Driver Software. The Display adapters entry is another likely cause, so expand that section, right click the items and update them.
Sometimes it can help to uninstall an entry and remove the driver. Don’t worry, the item will not stop working. Restart Windows and the device is detected as if it were new and a driver is installed for it.
