Microsoft says it will soon release a patch for an issue with Windows that dramatically decreased battery life on Intel's Core Duo platform, and other platforms too, when a USB device is connected to the computer.
"The TG Daily article brought to our attention that our existing workaround is difficult to implement," said Michael Burk, PR manager for Microsoft's client team. "We also learned that we will need to issue a BIOS update in addition to a Registry modification, to make sure that the fix will be stable." While the existing workaround, which we reported on earlier, is somewhat efficient in regaining substantial battery time for notebooks connected to USB 2.0 devices, Burk told us this new patch will go even further to address these new issues.
