关於XP对於使用Yonah的Intel Core Duo处理器的Napa笔电 搭配ICH7M会出现神秘的USB疯狂消耗电池的问题 那个网页是我一月多在Tom's Hardware Guide英文站看到的Daily 网址是http://0rz.net/9710L 印象中好像是Toms的工程师发现了这个问题，然後微软跟intel工程师就去想办法 然後上个月他们又发新闻说Microsoft to release patch for power drain bug 就是我给的网址，网址是http://0rz.net/7e170 嗯嗯 我当初也只看标题跟大纲 就想说买napa应该已经没问题了XD 不过刚刚稍微看一下内容才知道 微软对这个问题还是保密中 也不授权给任何网站发布他的技术文章 微软的技术文章有提供一个registry的解决办法 他们官方并不希望我们用这个方法，intel实验室还在研究从BIOS的根本解决方法 所以希望使用者等到他们发表，然後笔电厂商再发布新BIOS 而这个文章要有Microsoft Premier 限才可以看 不过我还是贴了 在下面XD 可以用它的方法作暂时的patch 据说可以增长电池续航力至少一小时 = =? 另外在一些外国的硬体讨论区也有很热烈的讨论 可以去参考一下 http://it.slashdot.org/article.pl?sid=06/01/28/1414209 其实我也很想买NAPA的机子 不然我也不会那麽热心..哈哈 不知道那台5562用起来如何? 可不可以在发表一些感想呀XD 它可能会成为我的第1台笔电喔~ 如果现在还没有说很成熟的话...那就还要等Merom核心的是也 不过我比较希望现在就买~ 因为49900这价钱还蛮OK的 这一台是极品呀XD 下面是Microsoft Knowledge Base KB899179的内容 A Windows XP SP2-based portable computer uses its battery power more quickly than you expect when a USB 2.0 device is connected View products that this article applies to. Partner Only Article Article ID : 899179 Last Review : July 12, 2005 Revision : 1.0 Important This article contains information about how to modify the registry. Make sure to back up the registry before you modify it. Make sure that you know how to restore the registry if a problem occurs. For more information about how to back up, restore, and modify the registry, click the following article number to view the article in the Microsoft Knowledge Base: 256986 (https://premier.microsoft.com/kb/256986/ [microsoft.com]) Description of the Microsoft Windows registry SYMPTOMS Consider the following scenario. You install Microsoft Windows XP Service Pack 2 (SP2) on a portable computer. Then, you connect a USB 2.0 device to the computer. In this scenario, the computer uses its battery power more quickly than you expect. CAUSE Windows XP SP2 installs a USB 2.0 driver that initializes any connected USB device. However, the USB 2.0 driver leaves the asynchronous scheduler component continuously running. This problem causes continuous instances of memory access that prevent the computer from entering the deeper Advanced Configuration and Power Interface (ACPI) processor idle sleep states. These processor idle sleep states are also known as C states. For example, these include the C3 and C4 states. These sleep states are designed, in part, to save battery power. If an otherwise idle portable computer cannot enter or maintain the processor idle sleep states, the computer uses its battery power more quickly than you expect. RESOLUTION Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall your operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk. To resolve this problem, add the EnIdleEndpointSupport entry to the USB registry key. To do this, follow these steps:1. Click Start, click Run, type regedit, and then click OK. 2. Locate, and then click the following registry subkey: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\USB Note If the USB subkey does not exist, create it. To do this, follow these steps:a. Select the Services key. On the Edit menu, point to New, and then click Key. b. Type USB in the New Key #1 box to name the new key "USB." 3. Right-click USB, point to New, and then click DWORD Value. 4. In the New Value #1 box that appears, type EnIdleEndpointSupport, and then press ENTER. 5. Right-click EnIdleEndpointSupport, and then click Modify. 6. In the Value data box, type 1, leave the Hexadecimal option selected, and then click OK. 7. Quit Registry Editor. STATUS Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
