關於XP對於使用Yonah的Intel Core Duo處理器的Napa筆電搭配ICH7M會出現神秘的USB瘋狂消耗電池的問題那個網頁是我一月多在Tom's Hardware Guide英文站看到的Daily 網址是http://0rz.net/9710L 印象中好像是Toms的工程師發現了這個問題，然後微軟跟intel工程師就去想辦法然後上個月他們又發新聞說Microsoft to release patch for power drain bug 就是我給的網址，網址是http://0rz.net/7e170 嗯嗯我當初也只看標題跟大綱就想說買napa應該已經沒問題了XD 不過剛剛稍微看一下內容才知道微軟對這個問題還是保密中也不授權給任何網站發布他的技術文章微軟的技術文章有提供一個registry的解決辦法他們官方並不希望我們用這個方法，intel實驗室還在研究從BIOS的根本解決方法所以希望使用者等到他們發表，然後筆電廠商再發布新BIOS 而這個文章要有Microsoft Premier 限才可以看不過我還是貼了在下面XD 可以用它的方法作暫時的patch 據說可以增長電池續航力至少一小時 = =? 另外在一些外國的硬體討論區也有很熱烈的討論可以去參考一下 http://it.slashdot.org/article.pl?sid=06/01/28/1414209 其實我也很想買NAPA的機子不然我也不會那麼熱心..哈哈不知道那台5562用起來如何? 可不可以在發表一些感想呀XD 它可能會成為我的第1台筆電喔~ 如果現在還沒有說很成熟的話...那就還要等Merom核心的是也不過我比較希望現在就買~ 因為49900這價錢還蠻OK的這一台是極品呀XD 下面是Microsoft Knowledge Base KB899179的內容 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.
