Percussive maintenance refers the use of physical concussion, a knock or a tap, in an attempt to make a malfunctioning device work instead of asking for professional help.
“敲打式維護”指設備有故障的時候,不找專門的維護人員,而是用敲打的方式讓其恢復運轉。
Percussive maintenance happens when your piece of electronic device — television, computer, etc — won't work, you give it a sharp unscientific whack to revive it. And it often works.
電視或電腦等電子設備出故障的時候,你有時會通過敲打的方式讓其恢復運轉。而且這種方式通常都會管用。
For example:
My computer keyboard didn't work yesterday, I couldn't type even a single letter. After a percussive maintenance, it worked like a newly-bought.
昨天我的電腦鍵盤壞了,連一個字母都打不出來。我給敲打了一下,然后就跟新買的一樣好用了。
