Unfixed USB Bugs Will Drain Your Laptop Battery
Windows XP Profesional Service Pack 2
Again unfixed Windows XP Service Pack 2 confirmed by Microsoft. This time will drain your laptop battery when you plug a peripheral on USB slot. In a statement through its public relation firm, Waggener Edstrom Inc., Microsoft also admitted that the flaw, which lies in the ACPI (Advanced Configuration and Power Interface) driver of Windows XP SP 2, will remain without an easy-to-apply fix indefinitely. The ACPI is latest standard for USB peripheral ports on Laptop and part of the operating system's power management scheme for USB 2.0.

The bug will affect Intel-based Laptop. And the fix will still wait to be released to public since it required deep understanding of Operating System and there are also risk involved when apply the fix. Microsoft claim the fix is not for ordinary users because of the reason above.

"While there is a noticeable impact on battery life when USB 2.0 devices are plugged into some specific models of laptop computers, these systems are still fully functional and newer systems have significantly longer battery life than their predecessors, whether a USB 2.0 device is plugged in or not," Microsoft said in its statement.
