Napa notebook USB power problem

Before we had invoked TGDaily reported Napa laptops Laptop Battery to access the USB2.0 device a lot of power sources, in a test in which they found in Intel's latest mobile platform, to insert some USB2.0 devices will lead to the battery usage time reduced by 40% or more, so They think this is a Core Duo-Bug. But now AnandTech conduct a more detailed report, and revealed a number of other facts.

Through 5 of the notebook computers from different vendors test, AnandTech found that the so-called Core Duo bug is not an independent phenomenon, in fact, have appeared in all the tested platforms, including the Sonoma platform, or those using single-core CPU notebooks . The site also reported that Microsoft has been quick fix for this USB charge power problem, but only Inspiron 510m a temporary solution.

AnandTech's article this way:

"Napa notebook bug due to the loss of 17% of battery time, but while using Sonoma, W5A lost 25.5%. Therefore, it is said that this is just Core Duo, the problem is wrong. Sonoma platform and the Core Duo platform to be deeply in the question of harm. through the analysis we have come to believe that Microsoft's inference: The problem exists in all entered into the C3 Deep Sleep in systems such as power-saving mode. "

, "XO" computer OLPC Foundation, recently said that, in order to enhance battery Inspiron 500m life, the next generation of products XO-2 is likely to switch to ARM processor.

OLPC chairman Nicholas Negroponte (NicholasNegroponte), the next generation of XO XO-2 is basically using ARM processors have been identified. At present, the generation of XO XO-1 uses a Geode processor, AMD earlier.

This, OLPC chief technology officer Ed McNealy (EdMcNierney), said: "XO-1's power consumption is only 5W, a lot of people think that this is already very low, but we believe that there is still high."

McNealy also said, ARM processor can not only meet the basic needs of users, but also reduce power consumption. After the switch to ARM processors, the 312-0305 biggest problem is that operating system.

OLPC said that, when the willingness to provide Linux and Windows dual-boot option. In addition, OLPC has already made contact with Microsoft, hoping to be launched for the ARM processor, a Windows system.

McNealy also said that second-generation 312-0306 products XO-2 will be available within the next 18 months, which will be equipped with dual touch-screen.
