Core Duo Power Sapping Bug is Microsoft Issue

Posted by ryuzaki0 on from the explore-all-possibilities dept.

illusoryphoenix writes "A few weeks ago, Tom's Hardware noted a significant reduction in battery life of the Core Duo processors it tested when USB devices were inserted. Intel claimed that Microsoft had a bug in their USB drivers, while Tom's Hardware was unable to reproduce the same result for any of the other Pentium M microarchitecures. This issue has finally been publicly confirmed by Microsoft to be a USB driver problem which keeps the processor from entering advanced sleep states."

  1. Re:BIOS Fix? by gstoddart · · Score: 4, Insightful
    Microsoft outlined a fix that involved modifying the registry key for USB 2.0. However, since then the company has realized that this is an impractical fix for most users, and is working on a new fix that could involve a BIOS update patch

    What! Microsift to patch the BIOS
    Not on my notebook

    Indeed. Microsoft can easily patch their own friggin' registry monstrosity.

    Patching the BIOS of the machine is an outrageously bad suggestion, and a bad precedent.

    How long before MS patches everyone's BIOS into oblivion or DRM hell?
