Troubleshooting unplanned Windows automatic wake-ups

Whenever I finish working with my computer, I never power it off. Instead I send the computer into sleep or hibernate mode.

They tried to gather events using Windows PowerShell and export them to CSV format (to view events in Excel), but finally they gave… Read More »

Troubleshooting knowledge base

Some of us have dealt with the frustration of dealing with a problem we know we’ve experienced before, but didn’t register it properly. The outcome?
