The computer is safeguarded is to raise the computer to use efficiency and the important measure that prolong computer service life. The computer safeguards main body to show in two respects: It is the maintenance of hardware; The 2 maintenance that are software. The maintenance of computer hardware basically has the following: (1) the join that any moment should assure power supply cord and line is firm and reliable; (2) the magnetic head that cleans floppy disk driver regularly (wait like 3 months, half an year) ; (3) the computer often should be in athletic condition, avoid long-term and unused need not; (4) report should be appended to peripheral equipment first when switching on the mobile phone, report is appended to lead plane after; Close machine Shi Yingxian to shut main engine, each peripheral equipment involves after, after switching on the mobile phone, cannot close instantly machine, close machine hind to also cannot switch on the mobile phone instantly, interval answers among 10 seconds above; (5) floppy disk driver is being read when writing, cannot take out floppy disk forcibly, do not feel dish of bare side at ordinary times; (6) when undertaking clavier is operated, key stroke has not exerted oneself to do sth. fierce, can affect the life of clavier otherwise; (7) the ribbon of printer should be changed in time, when ribbon color very shallow already, when discovering ribbon has damaged especially, answer to change instantly, lest the pinhead of printer of foreign matter flyblow, the influence prints the flexibility of needle movement; (8) often notice to clear the dirt inside the machine and brush try clavier and box surface, the computer need not when want a lid to go up dustproof cover; (9) fall in the circumstance that append report, do not move lead plane and other peripheral equipment at will.
