Windows Update Fixes Laptop Battery Drain
14 Jan
Summary
- Windows update KB5074109 addresses NPU idling power drain.
- NPUs may have unnecessarily consumed battery power on idle laptops.
- The update includes bug fixes and driver updates for NPUs.
Microsoft has released Windows update KB5074109, targeting a notable battery drain issue affecting laptops with Neural Processing Units (NPUs). For many users, NPUs have remained idle and active even when the laptop is not in use, leading to reduced battery life. This update, available as of yesterday, aims to rectify this power consumption problem.
The update specifically addresses an "issue" where NPUs continued to draw power while laptops were idling, a situation that could be particularly frustrating for users seeking better battery performance. This fix is now rolling out to users via Windows Update, addressing a common complaint about the underutilized NPU hardware.
Beyond the NPU power fix, KB5074109 also includes a suite of general bug fixes and updated drivers. It also introduces new Secure Boot certificates and an updated version of the WinSqlite3.dll file, contributing to overall system stability and security.
