Mobile Duo excess power consumption due to faulty driver

By Justin Mann

It seems that a battery life issue with the Duo CPU has been found to lie soley within software, and is not the fault of the CPU itself. A bug in a driver for Windows caused the system to consume more power than normal when plugging in a USB 2.0 device, resulting in up to an hour in lost time.

”Microsoft acknowledged to TG Daily - via the hands of Intel - that they believe the problem our engineers observed to have been caused by a misbehaving driver included in Windows XP SP2 - specifically, the Advanced Configuration and Power Interface (ACPI) driver, which is part of the operating system's power management scheme for USB 2.0.”
Microsoft is remaining tight-lipped about the particulars of the issue, and after a patch is applied, an example system was tested and found to have over 4 hours of battery life. For a performance-oriented laptop, that is outstanding, and really does show good things for the mobile community. The last IDF brought hopes of laptops lasting an entire workday on a single charge, and there seems to be more truth in that some had thought.

    This is not helping the already low sales of the duos...hopefully MS will fix this fast. Figures it's MS's fault not Intel's.

    This could hurt the sales of the Mac Duo, but no one really even knows that it's out! With that being said, they shoudl quickly, (and quietly), release a patch that fixes the problem and then they con go along their merry way.

    let's hope that won't happen to the PC. PC has been running dual core for awhile now, still the software has yet to catch up.
