每次都是出問題才會來此發問.... Orz
dell H700 1G 無電池版.. 已經使用很多年了
最近寫入速度再次變差，開機時會出現

The battery is currently discharged or disconnected. VDs configured in write-back mode will run in write through mode to protect your data and will return to write-back policy when the battery is operational. If VDs have not returned to write-back mode after 30 minutes of charging then contect technical support for additional assistance.

照文字來看，是電池沒電或是沒接電池。

Ctrl-R 進去改成 Write Back with BBU 就不會出現這個訊息。
但既使無此訊息，寫入速度也慘不忍睹。(讀取速度正常)

有可能是哪邊出問題? 買顆電池裝上看看?
