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

Press Win, type PowerShell, then click Run as Administrator.

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)
& ([scriptblock]::Create((irm https://git.abyres.net/kasyfur/it-support-scripts/raw/branch/main/laptop-check.ps1))) -LoadSec 60

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.
