iRobot Roomba副廠電池

為了省錢買了一個副廠電池，結果用不到一年就掛點了，嚴格說起來只有十個月不到。到最後一出動就停了。

而原廠電池使用二年，每周一、三、五掃地（約15坪），周末可能會有1~2次掃房間（約4坪），到最後只剩不到10分鐘。

副廠的一顆17XX用10個月，原廠的24XX用24個月，這樣算一算買原廠是比較划算！所以敗了原廠電池，在這裡先做個記錄，之後再來分享用多久。

筆電DELL E4300開啟AHCI在安裝完WIN7之後

Dell E4300的筆電，SATA若從IRRT轉成AHCI，無法照一般方式完成操作，需多一個更改機碼的動作（步驟3）

1.安裝Intel Rapid Storage Technology(IRST可在Intel的網站下載)，舊名為Intel Matrix Storage Manager.
2.修改機碼HKEY_LOCAL_MACHINE\SYSTEM\ CurrentControlSet\services\msahci\Start，機碼值由3改成0．（如文章最後附的機碼win7ahci.reg內容）或是使用微軟所提供的技術支援（http://support.microsoft.com/kb/922976）．

3.修改機碼，如文章末附的機碼Intel GM45 AHCI.reg內容所示．

4.重新啟動筆電，進入BIOS將SATA由IRRT改成AHCI，按下apply，接著離開BIOS．
5.此時筆電重開機，進入WINDOWS隨即自動安裝AHCI driver，安裝完成再度重開機．
6.安裝driver，重開機二次後，即大功告成．
