標(biāo)簽應(yīng)包含指導(dǎo)用戶正確安裝和使用的重要信息。正確貼標(biāo)產(chǎn)品是確保用戶個(gè)人和財(cái)產(chǎn)安全的基本措施之一。標(biāo)記需要耐用性和引人注目。正常使用后，標(biāo)記不應(yīng)脫落，內(nèi)容應(yīng)清潔和區(qū)分。這方面常見問題是沒有中文標(biāo)識(shí)，沒有工廠名稱或商標(biāo)，沒有型號(hào)代碼或型號(hào)規(guī)格等。則可能是假冒偽劣產(chǎn)品。 </p> <p> 2、正常工作條件下的加熱不符合要求。 </p> <p> 電源適配器的功能是改變電壓。在電壓轉(zhuǎn)換過程中，由于損耗，需要消耗一部分電能。在電能轉(zhuǎn)換成熱能后，部分熱能通過輻射，對(duì)流和傳導(dǎo)傳遞到周圍環(huán)境。熱能的另一部分自身被吸收，使電源適配器的溫度變暖。所以當(dāng)周邊的環(huán)境溫度過高時(shí)，我們應(yīng)該停止電源適配器的使用。 </p> <p> 3、短路和過載，存在隱患安全隱患。 </p> <p> 在輸出短路，電容器或二極管短路的情況下，電源適配器的內(nèi)部損耗急劇增加，導(dǎo)致每個(gè)部件的溫升。電子電路的設(shè)計(jì)和應(yīng)用應(yīng)確保在異常工作和故障條件下，產(chǎn)品各部分的溫升不能超過規(guī)定的要求，否則短路的后果不堪設(shè)想。甚至?xí)砘馂?zāi)。 </p> <p> <br /> </p> <p> <br /> </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="海南線性電源適配器" src="http://tyunfile.71360.com/UploadFile/szxskj/637142795371904297/5792425.jpg"></div><p> 筆記本電腦是一種高度集成化的用電設(shè)備，其對(duì)電壓和電流的要求很高。同時(shí)其內(nèi)部電子元器件也相對(duì)脆弱，如果輸入的電流或電壓不在相關(guān)電路的設(shè)計(jì)范圍內(nèi)，就可能造成燒毀芯片或其他電子元器件的嚴(yán)重后果，所以筆記本電腦供電設(shè)備的電源適配器和電池的穩(wěn)定性就變得十分重要。 </p> <p> 與筆記本電腦供電相關(guān)的故障很多，一方面是由于筆記本電腦主機(jī)內(nèi)保護(hù)隔離電路和充電控制電路等相關(guān)電路出現(xiàn)問題造成的，另一方面則是由于電源適配器和電池本身出現(xiàn)問題造成的。 </p> <p> 電源適配器常見故障主要包括無電壓輸出或輸出電壓不穩(wěn)等。筆記本電腦電源適配器的輸入電壓通常為交流電100V～240V，如果電源適配器的接入電壓不在這個(gè)區(qū)間內(nèi)，那么就很有可能造成電源適配器燒毀的故障。電源適配器自身的發(fā)熱量很大，如果在使用過程中散熱條件不好就可能導(dǎo)致內(nèi)部電路無法正常工作，從而造成無電壓輸出或電壓輸出不穩(wěn)的故障。 </p> <p> 由于筆記本電腦電池自身問題造成的故障主要包括電池?zé)o電壓輸出、無法充電等。筆記本電腦電池的電芯充電和放電都具有一定的限度，如果超過其限度就可能造成損壞。電池內(nèi)的電路板對(duì)充放電有一定的保護(hù)作用，但是其本身也有可能產(chǎn)生故障，從而造成電池出現(xiàn)無電壓輸出或無法充電的故障。 </p><div
