# it-support-scripts
|
||
|
||
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**, choose **PowerShell**, then click **Run as Administrator**.
|
||
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.
|
||
|
||
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. |
