Routine preventive maintenance at professional service centre, when there is no physical problem or symptom noticed, gives better life and mobility to the Laptop. Because of preventive maintenance dust accumulation does not happen in electronic part and hence chance of absorbing moisture is minimized to great extent, resulting no erosion, ensuring zero rust in electronics circuit/chips. Due to cleaning and greasing of hinges, stiffness effect gets zeroed and hence it remains smooth. Otherwise, when hinges gets stiff, it results pulling out the cabinet from front and bottom side, making greater and costlier damage to laptop.
Also, it is must to have antivirus software installed to avoid damage to OS, Application software and data file.
It is advisable to have patience while working on laptop and allowing sufficient time to open or close the applications & data files are wise steps to follow. Never get desperate to open number of applications, at a time, before previous application opened by you is stabilized. Do not forcibly close the applications already opened. Try to close one by one application allowing time to settle down. Try to open one by one application too, once you find previous application is fully opened and stabilized. Do proper shutdown before closing the Laptop screen. As far as possible, do work in cool environment.
