Uso del computer (cont.)

3Rimuovere la batteria principale dal relativo alloggiamento e, se presente, la batteria aggiuntiva dall’alloggiamento dei moduli.

4Scaricare a terra l’elettricità statica del corpo toccando qualsiasi superficie metallica non verniciata sul retro del computer.

Durante l’intervento toccare periodicamente la superficie metallica non verniciata per scaricare l’elettricità statica eventualmente accumulata che potrebbe danneggiare i componenti interni.

Protezione dalle scariche elettrostatiche

L’elettricità statica può danneggiare i componenti elettronici del computer. Per evitare possibili danni, scaricare l’elettricità statica dal corpo prima di toccare un componente elettronico del computer, ad esempio un modulo di memoria. A tale scopo è sufficiente toccare una superficie metallica non verniciata sul retro del computer.

Mentre si lavora sui componenti interni del computer, toccare periodicamente una superficie metallica non verniciata sul retro del computer per scaricare l’eventuale carica elettrostatica accumulata dal proprio corpo.

Per evitare danni causati dalle scariche elettrostatiche è inoltre possibile adottare le seguenti precauzioni:

•Quando si estrae dalla confezione un componente sensibile alle cariche elettrostatiche, non rimuoverlo dall’involucro antistatico fino al momento dell’installazione. Prima di aprire l’involucro antistatico, accertarsi di avere scaricato l’elettricità statica dal corpo.

•Prima di trasportare un componente sensibile alle cariche elettrostatiche, riporlo in un contenitore o involucro antistatico.

•Maneggiare tutti i componenti sensibili in un’area priva di energia elettrostatica. Se possibile, usare tappeti antistatici per il pavimento e il banco di lavoro.
