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
- Press Win + X, choose Terminal (Admin), then click Yes.
- Paste and press Enter:
[Net.ServicePointManager]::SecurityProtocol='Tls12'; irm https://git.abyres.net/kasyfur/it-support-scripts/raw/branch/main/laptop-check.ps1 | iex - Run it twice: once plugged in and once on battery. Close other apps first.
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 |
Requirements
- Windows 10 or 11, run as Administrator
- Office network or VPN (to reach git.abyres.net)
Options (for IT)
# Skip the load test
& ([scriptblock]::Create((irm https://git.abyres.net/kasyfur/it-support-scripts/raw/branch/main/laptop-check.ps1))) -NoLoad
# Longer load test (60 s)

Troubleshooting
| Problem | Fix |
|---|---|
irm cannot connect |
Connect to the office network or VPN |
| "Not run as Administrator" flag | Reopen with Win + X → Terminal (Admin) |
| Temperature not changing | The built-in sensor isn't live; use HWiNFO or Acer Care Center |
Changelog
- v2 (27 Oct 2026): Battery health from battery report, CPU load test, shutdown cause, interrupt/DPC time, power mode via Windows API
- v1 (27 Oct 2026): Initial release
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.
