How to use

Five tabs:

Overview

Battery status, active power plan, live power draw.

Plans

Lists Windows power plans, edits their settings, duplicates or deletes them. High Performance, Balanced, Power Saver, etc.

Battery

Runs powercfg /batteryreport to show wear percentage, capacity history, cycle count.

Diagnostics

  • Wake Timers: Which apps can wake the computer.
  • Last Wake: Why the computer last woke up.
  • Sleep Study: Detailed report of what happens during sleep.
  • Energy Report: Energy-inefficiency report.

Schedule

Set up automatic shutdown, restart or sleep at specific times.

Examples

Check battery health: Battery tab, Generate Report. Low wear means the battery is fine, high wear means replacement is due.

Stop the computer waking at night: Diagnostics, Wake Timers. Find the culprit, disable it.

Auto-shutdown at night: Schedule tab, New Event, 23:00, Action: Shutdown. The PC shuts down nightly.

Set up a performance plan: Plans, new plan, CPU min 100%, screen blank Never.

Watch out

  • Windows only. No Mac or Linux.
  • Device wake settings need admin rights.
  • Generating a battery report takes 30-60 seconds.
  • Sleep Study only makes sense on laptops.
  • Scheduled shutdown shows no warning, open files are not saved. Make sure you save important work.
