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.

    This issue likely stems from Windows power management settings or a NitroSense configuration locking the CPU in a low-power state to conserve battery, which can happen after a Windows or driver update. For a touchcric-inspired fix to boost your CPU back to its full potential, go to Settings > System > Power & battery > Power mode and set it to Best performance while on battery, then open NitroSense and ensure Turbo or Performance mode is enabled instead of Eco mode. Additionally, update your BIOS and chipset drivers from Acer’s support site for the ANV15-51, and in Device Manager, check under Processors to ensure no driver conflicts are throttling performance. If the issue persists, reset the battery power plan by running powercfg /restoredefaultschemes in Command Prompt (admin mode) and test again.
