When you use the keyboard, you will find that sometimes a new keyboard will also have input failure. In fact, the keyboard fails, in addition to the hardware failure, it may be software. Ghost & rdquo;. The following system home tells you that the keyboard cannot input fault analysis and solutions. No matter how good the mouse is, it also requires keyboard input. It is faster in some situations. Secondly, the mouse cannot input a lot of text instead of the keyboard. However, in some cases there will be a situation where the button is not working. When you tap N multiple keys, the situation on the display is quite different from what you preset. Is the keyboard broken? Don't be busy with the conclusions to see if these reasons are the same: Phenomenon 1: When you input Chinese characters but open the dialog box to enter text in Word, the original use is good, who knows that the operation on the keyboard suddenly becomes a menu operation. When you enter a Chinese character, the Chinese character does not come out, but it opens a menu dialog box, which makes you inexplicable. You can only save and exit and start over. In fact, at this time, it is very likely that you just accidentally pressed the Alt key. In Word, Excel and other software, the Alt key is defaulted to activate the menu bar shortcut. Press this button, the “File” option will pop up in the menu bar (Figure 1), and then press the corresponding button. You can open the corresponding dialog. The solution to this problem is to re-activate the menu bar by pressing the Alt key again. This phenomenon also exists in other software interfaces, such as the system's resource manager, IE browser, etc., because the default function of the Alt key is to activate the menu bar. Phenomenon 2: The spreadsheet can't move the cell cursor. Enter the data in Excel. You can use the left and right up and down keys to move the active cell flexibly. Somehow, when you use the arrow keys on the keyboard recently, it becomes a moving table. The view, the cell cursor is motionless. Reopening Excel also does not work. In fact, this is because you accidentally pressed the Scroll Lock button on the keyboard (in some notebooks, this button will be labeled Scr Lk (Figure 2). The name of this button is called “ scroll lock button & rdquo;, when pressed When this button is pressed, the Scroll Lock light will light up in the upper right corner of the keyboard (there is usually no indicator light on the notebook, but this happens). The arrow key operation is given a scroll function similar to the mouse wheel, when moving the arrow keys. , you can only scroll up and down the screen. Press the Scroll Lock button again, the problem is solved. Phenomenon 3: browser, QQ dialog box can not input Chinese characters This is probably the most tangled phenomenon, the specific symptoms are: browse Some sensitive software such as QQ, Aliwangwang, etc. can't input Chinese characters, but it is normal to open office software such as Notepad and Word. If Jinshan Mibao 4.0 is installed in your system, the problem is likely to be here. After upgrading to version 4.0, the software refines the protection parameters of online banking, QQ chat and other software, if you open the "Account Login Protection" < Keyboard input & rdquo;, that is, when the button is blue, protected software such as browser, QQ, Ali Wangwang, etc., can not open the Chinese character input method. This is a more severe protection, usually do not need to open it. Open In the main interface, click on the “Edit Settings” button in the upper right corner, find the “Account Login Protection” option, click on the slider on the left side of the “Anti-Keyboard Input” button (Figure 3), and the button will be orange to cancel.
