前天晚上同事去維修設備，需要修改一下觸摸屏程序；用miniUSB線(xiàn)與觸摸屏連接，惠普筆記本直接黑屏，不能開(kāi)啟；給我電話(huà)，也沒(méi)說(shuō)清，就說(shuō)他電腦黑屏了，讓我第二天早上去客戶(hù)那處理一下，結果我把數據線(xiàn)連上，沒(méi)多久筆記本（ThinkPad）USB口發(fā)出焦味現在公司兩臺筆記本都掛了，坐等新電腦到來(lái)……
這已經(jīng)是第三次與該品牌觸摸屏通訊時(shí)燒電腦USB口了！
各位大神，難道是我哪里操作失誤？煩請指點(diǎn)�。�！

怎么知道觸摸屏接地良好的？用萬(wàn)用表測了嗎？

我就見(jiàn)過(guò)客戶(hù)設備接了地線(xiàn)，可是設備外殼還是帶著(zhù)110V的電，那個(gè)地線(xiàn)接地端斷了。
