The keys of the keyboard can be removed, and it may be useful to clean up the clutter inside.

Bad keyboards and other people's keyboards don't work.

The value of the general keyboard without repair, **cheap, buy a new one.

1. The numeric keypad on the keyboard fails: This is the lowest level mistake that many novice friends will often make, a fierce opening is like a desktop keyboard, resulting in the failure of the keyboard numeric keypad (0123456789) Most of the reasons are that we turn off the numeric keypad, you can see if the numlock key is on, corresponding to a numeric keypad light on it, press the numlock key on the light to turn on the numpad. There are also some notebook novice friends who often ask why the letter keys on the right part of my notebook keyboard are indeed numbers instead of letters, which is very tangled!

In fact, this is because the number keys of the notebook are combined with the letter keys, when the number keypad is turned on, part of the letter keys on the right are arranged into number keys, mainly because the notebook keyboard is relatively small, and the manufacturer has set up an intelligent switching function.

2. Part of the keyboard keys on the keyboard fails, which is a key failure without any regularity: causing the failure of some keyboard keys, most of this situation is the failure of the internal circuit board of the computer keyboard, this phenomenon is generally because there is dirt on the road board or conductive plastic, so that the two can not be connected normally. Other factors are also possible, such as:

The keyboard plug is damaged, the wiring is faulty, the motherboard is damaged, the CPU is not working properly, etc., but it is not the main cause.

First of all, it is unlikely that the laptop is a hardware conflict (not installing other hardware by itself).

And then there are several possibilities:

1. System problems. Most of the system files in pirated or goest systems are changed, as this may speed things up, but they can also break the stability of the system (both sides of the story).

2. Software conflicts, which are divided into two points:

1) The software comes with malicious ** (virus), which damages the system or driver (the latter is less likely);

2) There is an option in the software that disables the mouse and keyboard (only possible. I haven't met it though).

3. Hardware damage, although it sounds impossible, but sometimes it is like this, because we don't think about it.

Press the numlock key to lock it, you can connect the external keyboard and press the numlock key again, and it will return to normal.

A keyboard is a kind of instruction and data input device used to operate the equipment, and also refers to a set of function keys (such as typewriters, computer keyboards) that are arranged to operate a machine or equipment by the system. The keyboard is also part of the musical instruments that make up the keyboard, and it can also refer to the instrument that uses the keyboard, such as the piano, digital piano, or electronic keyboard, etc., and the keyboard helps to practice typing.

The keyboard is the most commonly used and most important input device, through which English letters, numbers, punctuation marks, etc. can be input into the computer, so as to issue commands and input data to the computer. There are also keyboards with various shortcut keys. Over time, there have been separate products on the market with various shortcut functions**, with dedicated driver and configuration software, which can also be used individually on compatible machines.

Shopping. 1.The tactile feel of the keyboard.

As the input device that is most touched on a daily basis, the feel is undoubtedly the most important. The feel is mainly determined by the strength of the keys and the degree of resistance. Judging the feel of a keyboard, it will be tested from the aspects of whether the key elasticity is moderate, whether the key force is uniform, whether the keycaps are loose or shaky, and whether the key travel is appropriate.

Although different users have different requirements for the elasticity and travel of the keys, a high-quality keyboard should be able to meet the usage habits of the vast majority of users in these aspects, and the uniform force of the keys and the firm keycaps must be ensured, otherwise it may lead to key jamming or fatigue the user.

2.The appearance of the keyboard.

The exterior includes the color and shape of the keyboard, a beautiful and stylish keyboard will add a lot of color to your desktop, and an old-fashioned keyboard will make your work more dull. So, for keyboards, as long as you think it's beautiful, like, and practical.

3.The workmanship of the keyboard.

The cost of a keyboard is lower, but that doesn't mean it's easy to handle. The surface and edges and corners of a good keyboard are delicate and delicate, the letters and symbols on the keycaps are usually laser engraved, and there is a concave and convex feeling when you touch it.

The corners of the keyboard should not be sharp. The regular keyboard has CapsLock (letter case locking), numlock (numeric keypad locking), and scrolllock three indicators to be on.

ASUS laptops can turn on the numeric keypad in the following ways:

1. A notebook with a 14-inch keyboard can open the numeric keypad through the FN+NUMLK shortcut key;

2. With a pen with a 15-inch keyboard and above, the slag notebook can be directly pressed the numlk key to open the numeric keypad;

3. If you don't have a notebook with numlk buttons, you can open the numeric keypad through the fn+home button.

Use the steps above to switch the number keys.
