I'm using the Acer Nitro V 15 ANV15-51. My computer was working as it should a week or so ago, but for the past week, my processor has been running at a constant 0.40 GHz while on battery. Knowing my computer's specifications, I know it should perform better, but I can't use it.

    Hi Ibo_Can,

    What you're seeing is expected behavior for the Nitro V 15 ANV15-51. The CPU base speed of 2.4 GHz is normal, and the drop to ~0.39 GHz on battery is part of Acer’s aggressive power-saving strategy. This helps extend battery life but severely limits performance — especially on gaming laptops like this one.

    💡 Important Tip: For optimal performance, especially during gaming or heavy workloads, always keep the power adapter connected and ensure the battery is fully charged to 100%. Running solely on battery will throttle the CPU and GPU, making the system feel sluggish.

    This behavior is consistent across Nitro models and is not a defect — it’s by design to preserve battery health and reduce heat.

    Let us know if you’re seeing performance drops even while plugged in — that could point to a different issue like thermal throttling or power delivery limits.

    Hi,

    the problem isn't that it's 0.38 GHz, but that it stays constant at that speed. For example, when I open a browser, I can't navigate pages at normal speed, or programs open five times slower. As you can see, I'd expect a performance improvement based on usage, but it doesn't.
