Looking at all the parts of the books, the most easily into the gray areas than the keyboard. I have many friends around like the keyboard thoroughly cleaned, but suffer from removing the keyboard don't know where to start. Of course, as long as we buy is licensed, in the first year the firm can provide free maintenance service, if it is used for second-hand books or books has been the warranty, it can only own to carry forward the spirit of DIY. In fact, remove the keyboard is not complicated, as long as to find a breakthrough, you will find that the original is so simple! Now I take my IBM ThinkPad 390 as an example, Shoubashoujiao you remove the keyboard. Before work must first prepare a Phillips screwdriver, a pair of tweezers and a blade. The first step, to find a breakthrough. Any screws are not exposed at first glance the keyboard keys, only to see the rest of the indicator panel except. But as you can see from Figure 1, in the plate below panel hides two screws to fix the keyboard. The best use of the hard thin blade like demolition, insert the gap slowly the tailgate lift lever down. The second step, find organs. When the two screws screwed down, try to lift the keyboard, but it was also what fixed to live, then down the keyboard around looking for, and in the hidden on the upper right corner found the "authority", as long as the baffle plate force to push, keyboard immediately turns up. The third step, lift the keyboard. Now only few bayonet fixed below the keyboard to keyboard, the keyboard up and then to the opposite against the direction of travel, as shown in Figure 3, but pulled out the keyboard at the same time we must be careful, do not force a jerk off the connecting line keyboard back. The fourth step, the keyboard. Connected with the data line how can the keyboard cleaning? In fact, the three beam data line is inserted into the vertical connector on the motherboard in books, as shown in Figure 4, when both sides use tweezers grip evenly pull up and pull connector, you can loose the data line, the remaining two according to this method removed. After these four steps, the keyboard was successfully removed, dirt when not only can thoroughly clean the keyboard, also the way to clean the dust inside the books: for example, CPU fan dust, let oneself beloved books hull. Cleaning after on the keyboard mounted back, installation time must pay attention to the first plurality of bayonets on a hard to succeed. Of course, the market this brand different, different models, so the internal structure of manufacturing is not the same, but as long as the continuous exploration and many mental and physical work, infer other things from one fact, believe that you can make this one's face glowing with health.HDkservice manual download site
