Q: My Windows 10 PC has been failing to wake up after entering "sleep mode." The only way I can bring the PC back to life is to unplug the power cord, then plug it back in to restart the PC. As a temporary solution, I set the PC to never enter sleep mode. Is there a better solution?

A: Some PCs have this problem after being updated to a newer version of Windows 10.
Sleep mode is a reduced power consumption state that automatically begins shortly after a Windows 10 PC is left idle. Normally, a PC awakens because someone pushed the power button, moved the mouse or touched the keyboard, but Windows 10 updates can prevent that.
Fortunately, there are several potential fixes that are relatively easy. They involve using the diagnostic feature "Windows Power Troubleshooter," adjusting the power settings or turning off a deeper PC sleep called "hibernate" (see tinyurl.com/ycnhsgjk).
The same site explains another potential fix: Making sure that your PC's software drivers (which enable PC components to talk to each other) are compatible with your version of Windows 10.
If you think that's more work than it's worth, you can leave PC sleep mode disabled (other readers can see how it's done at tinyurl.com/ybu5cjh9). You will just lose some power savings.
Q: While using the Internet Explorer 11 browser, I continually get a pop-up message urging me to update something called "Silverlight." Because I don't know what Silverlight is, I have been wary of updating it. Do I need the update? How can I stop the pop-up?
