Abyres IT support diagnostic scripts. All scripts are read-only and make no changes to the device.

laptop-check.ps1

This script checks a Windows laptop for performance, battery and throttling problems. It takes about 1 minute and includes a 30-second CPU load test.

How to run

1. Press Win + X, choose Terminal (Admin), then click Yes.
2. Paste and press Enter:

   [Net.ServicePointManager]::SecurityProtocol='Tls12'; irm https://git.abyres.net/kasyfur/it-support-scripts/raw/branch/main/laptop-check.ps1 | iex
   

3. Run it twice: once plugged in and once on battery. Close other apps first.
4. Email the laptop-check-<PC>-<time>.txt files from the Desktop to support@abyres.net.

The script also saves battery-report-<PC>-<time>.html to the Desktop.

What it checks

• Power source, charging status, power mode and CPU cap
• Battery health (current capacity vs design) and cycle count
• CPU load, top processes, and interrupt/DPC time
• 30-second full CPU load test, measuring clock speed under load
• Firmware throttling events, unexpected shutdowns with cause, and hardware errors (last 14 days)
• RAM, disk space and disk health

Reading the result

Lines marked [FLAG] are issues, and they are listed again in the SUMMARY at the end.

Finding	Likely cause
Load test under ~1,000 MHz	Battery/charger forcing throttling, or overheating
Battery under 60% of design	Battery worn, replace it
Battery draining while plugged in	Charger too weak or faulty
Sudden power loss shutdowns	Battery or adapter
One process with high CPU%	Software issue, not hardware
Power mode = Best power efficiency	Settings → System → Power & battery → change Power mode

Reference (i3-1315U, TravelMate P214-55): about 2,400 MHz plugged in and about 1,600–1,900 MHz on battery under load is normal.
