FRED HEALTH CHECK : battery

“Day 0 health check” (battery = green, temp = 24 °C)

• Vantage = battery care (Conservation Mode, Rapid Charge).

• Windows Settings → Power & battery = the real deal for screen/sleep timers.

How to use

• Run it once a week as Fred (admin PowerShell).
• It drops:
  • C:\FredChecks\fred-YYYYMMDD-HHMM.txt (all the summaries)
  • C:\FredChecks\battery-YYYYMMDD-HHMM.html (full battery report)

Notes

• Temps/fan: Windows doesn’t always expose fan RPM. If the temps line shows nothing or looks odd, that’s normal; you can spot-check with Open Hardware Monitor/HWMonitor when needed.
• SSD wear: Get-StorageReliabilityCounter only returns data if the drive/driver supports it. If empty, no problem.
• Disk timeouts: keep “Turn off hard disk (plugged in) = 0 (Never)”.
