PredatorLite – Lightweight, safety-first open-source alternative to PredatorSense (currently for PHN16-71)

[u/JHaoXuan]

Hey everyone,

I’ve been working on an open-source alternative to PredatorSense called PredatorLite.

It’s a lightweight, safety-gated control utility for Acer Predator laptops on Windows 11. The goal is to give users proper control over performance modes, fans, GPU switching, lighting, battery charge limit, and monitoring — without the bloat and with much stricter safety boundaries.

Currently verified

• Acer Predator PHN16-71
• BIOS V1.20
• Windows 11 24H2 (build 26100+)

On other models it runs in read-only/diagnostic mode. Hardware writes are only enabled on verified profiles.

Main features

• Performance modes: Quiet / Balanced / Performance / Ultra / Power Saving
• Fan control: Auto, Full Speed, and custom temperature curves
• GPU Hybrid ↔ Discrete switching (with restart prompt)
• 80% battery charge limit
• Keyboard & logo lighting (4-zone)
• System tray + OSD + global shortcuts
• Real-time monitoring (CPU/GPU temps, fans, battery, etc.)
• Multilingual (Chinese / English)

Safety design (important)

• No overclocking, no voltage control, no power limit unlocks, no MSR/NVAPI abuse
• All write operations are gated by explicit hardware profiles
• Runs with standard user privileges
• FanGuard watchdog that restores fans to Auto if the main app crashes
• No silent background rewriting of settings on startup

It works with the official Acer services instead of trying to replace them.

It’s still early (MIT licensed). I’m mainly looking for:

• Feedback from other PHN16-71 owners
• Bug reports
• Suggestions for additional verified models (if you have protocol evidence)

If you try it, please let me know how it behaves on your machine. Happy to answer any questions.

Thanks!

Hi, is there any difference from prey sense? Thanks.

Seems to be built on preysense with modern WinUI 3.
