In the purchase of a second-hand laptop , the first thing to do is clean up the outside love machine chassis and internal display, keyboard, touch screen and so on. Attention to different things to different treatment! Keep in mind first off. For cases, have used alkaline cleaning liquid dip a soft cloth gently wipe and finally use a relatively soft, dry cloth to dry.



For frequently used components to focus on clean, mouse, laptop battery touch pad surface dirt can not be due to the correct response can be a soft slightly damp cloth gently wipe the surface and then wiped dry soft cloth. Cleaning the keyboard, the vacuum should be fitted with the smallest soft mouth and will bond with the bond between the net absorption of dust, and then use soft cloth cap.


Used as a general sales businesses are the acquisition of large quantities, they do not pay attention to the appearance of machine cleaning and maintenance, and thus a considerable portion of the appearance of second-hand laptop is not very new, and some cases there are many scratches, good In the vast majority of laptop chassis colors are deep, the question is not a lot of clean-up with velvet touch lightly on the line like the Shan. As for the more delicate fingers must not display or cloth, the application of the wool soft brush gently a Shan Shan.
If the screen is dirty, you can use a clean cotton cloth or a fine brush laptop LCD screen on the LCD screen clothcareful to clean, can not use any cleaning chemicals LCD. And the use of time to pay attention to the protection of the screen. To determine the hand did not sweat or moisture, caused by excessive humidity will lead to short-circuit indicator device. This is something we must pay attention to in order to maintain the surface of touch pad clean and dry.
In addition, attention to the use of touch pad when typing or not to hand or against the touch pad on the wrist. As the touch sensor to the finger board to any mobile, if the hand on the touch panel, the touchpad will lead to poor or slow response. For laptop, the light must light take place. Especially in the run-time machine, the best place not to move.
The second thing is to organize its internal applications. laptop as a result of second-hand source of uncertainty, it is impossible for each hard disk drive is very very clean. Therefore the system of second-hand laptops may have a lot of garbage, including the long-running rubbish generated files and you do not need some other software, which not only takes up valuable hard disk space, but also reduces the operating speed of the machine.
If you do not use your battery when a long time, you must remove the battery from the machine and kept in dry, cool environment. We are all no objection to this point, but why here to make up for discussion? Because, here, to another build question: For the Ni-MH battery, the battery should be fully discharged and then save, save, or live? This is two kinds of different views of what it should be used? Many people think that we should adopt the former, but I thought that to save the battery charged is reasonable. Because: According to tests, Ni-MH acer btp-60a1 battery to save the best conditions to save about 80% charged. This is because the nickel-metal hydride batteries self-discharge high (10-15% a month or so), if the battery is fully discharged and then save, for a long time not to use, the battery self-discharge phenomenon will result in excessive battery discharge, will be damage the battery. Do not believe it? Then you think about buying a new nickel-metal hydride rechargeable batteries is not all there is electricity, which is the reason. Recommendation: more compared to correct the wrong point of view, from the maintenance of the battery to start in the right direction, otherwise it will backfire.
