一、鍵盤打不出字怎么回事

我(wo)們在使用(yong)電(dian)腦(nao)的時(shi)候(hou)，有時(shi)候(hou)發現鍵(jian)(jian)盤(pan)不靈了，打不出(chu)字了，這(zhe)可(ke)能(neng)是鍵(jian)(jian)盤(pan)與電(dian)腦(nao)連接出(chu)現故障或者鍵(jian)(jian)盤(pan)驅(qu)動出(chu)現問題導(dao)致(zhi)的，具體的原因有：1、供電(dian)問題，可(ke)能(neng)是USB接口沒有數據傳輸(shu)，換用(yong)其他USB接口試試。2、驅(qu)動問題，重新安(an)裝驅(qu)動或者更新驅(qu)動即(ji)可(ke)。3、電(dian)腦(nao)鍵(jian)(jian)盤(pan)損(sun)壞，需要(yao)更換鍵(jian)(jian)盤(pan)。

四、鍵盤選購指南

1、看手感：選擇一款鍵盤時，首先大家用雙手在鍵盤上輕敲幾下，試試手感。如在網絡選購可多看評論，咨詢下客服，查詢軟、硬度和彈性等，更可以到實體店親手體驗。2、看鍵帽：看鍵帽主要是為了看清上面的字跡。激光蝕刻，字跡平整，但無凹凸感，手指感官差。油墨印刷，鍵帽上有凹凸質感，手感舒適，但價格貴，長時間使用易脫落。3、看按鍵數目：鍵盤發展至今出現過83鍵、93鍵、102鍵、104鍵、107鍵等按鍵數目，目前市面上主流的是108鍵。4、看鍵程：很多人喜歡鍵程長一點的，按鍵時很容易摸索到。也有人喜歡鍵程短一點的，認為這樣打字時會快一些。一般建議鍵盤不算熟悉的用戶選鍵程長一點的鍵盤；對鍵盤比較熟悉的用戶，可選鍵程短一點的鍵盤。5、看鍵盤接口：目前大多數鍵盤使用的PS2接口，不過現在市場開始出現USB接口的鍵盤。USB接口鍵盤最大的特點就是可以支持即插即用，但是價格上要高于PS2接口的鍵盤，至于筆記本要用外置鍵盤則非USB不可。6、看噪音：相信所有用戶都很討厭敲擊鍵盤所產生的噪音，尤其是那些深夜還在工作、游戲、上網的用戶，因此，一款好的鍵盤必須保證在高速敲擊時也只產生較小的噪音，不影響到別人休息。7、看品牌和價格：最后一點就是看鍵盤品牌和價格了，同(tong)等(deng)質量，同(tong)等(deng)價格下當然挑選名(ming)牌大廠的鍵(jian)盤(pan)了，大廠品牌能給人一定的信(xin)譽度和安全感。
