Solve power and sleep problems in Windows 10 after upgrading

Don't give up on Windows, try these power and sleep mode fixes

Windows 10 is hard to avoid as Microsoft continues to push the latest version of its operating system. It works fine for most people, but if you are having power problems and sleep mode issues, try these fixes.

Windows 10 was released last summer and there have been some big updates since. Some people have found that after upgrading from an older version of Windows to 10, or 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.)

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.

There are a number of troubleshooters in Windows and these can sometimes fix problems. Right click the Start button and select 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.

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.

Right click the battery or power icon at the right side of the taskbar 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.

Power and sleep problems can be caused by faulty or incompatible hardware drivers. Updating them might cure the issues you are having. Click in the search box and enter Device Manager. Click the one labelled Control Panel in the results and Device Manager opens.

Left click an entry, such as Batteries to reveal the contents. Right click an item and select Update Driver Software.

It would be tedious to check them 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.

Finally, reboot the computer. Hopefully the power issues will be cured.
