typical keyboard.

Kates Playground Come Play
The keyboard is not just a Computer components suffering more breakdowns, although if it is one of the most exposed.
Let's take a look at the damage that may have, and some of the fault, are not really failures, if we can leave this disabled.
There are three types of keyboard, based on the type of connection you have:
Keyboard PS / 2:
PS / 2. See the purple connector.
is the most common type of keyboard, and as the name suggests is connected to the PS / 2 keyboard specific. This port is the one closest to the outside base plate, usually indicated in purple.
Faults often have few, almost all caused by misuse.
The most common is that by putting the forces and twisting of the connector pin PS / 2, which is obviously useless. Given this failure
we attempt to straighten the pin that has been twisted and reconnect it correctly.
can also be the case that by forcing us to break the PS / 2 motherboard, although this is now rare.
The solution is often more difficult, since in that case it is necessary to unsolder and re-solder the connector, and this is a rather delicate task.
View of the PS / 2 connectors. Violet is the keyboard and mouse green. On your right you can see the USB connectors.
A third possibility is to break the controller PS / 2 motherboard.
This fault if we can not fix. Before
three faults have the option of replacing the keyboard with a USB-connected keyboard.
USB Keyboard:
USB Keyboard. In this case it is a reduced keyboard (88 keys), which is the type often used by laptops.
This type of keyboard does not usually cause many problems, except those inherent faults USB port (already discussed in the tutorial on
Malfunctions USB ports.
The main concern is that there are many motherboards that do not enable the USB keyboard to the Post, so no we can use it until you're in Windows. However there are many boards that if they can enable the USB keyboard directly into the boot, usually by an option in the setup (which is usually an option with a text similar to Enable
USB Keyboard ).
wireless keyboards:
wireless keyboard. You usually sold as Desktop , ie keyboard and mouse set. To the right of the picture we see the receiver.
is a type of keyboard, as its name indicates, is not connected to the PC via cable, but work normally by radio frequency.
depend on a receiver if it is connected to the PC via cable, and can be connected either PS / 2 or USB either, so it is likely to have the same damage with a keyboard connected by cable to the PC, to which we must add a few.
First and foremost (although not really a fault) is that we run out of batteries. This type of keyboard is not exactly cheap to maintain and the batteries do not last too long, To this must be added that have a nasty habit of not warning that they are running out of batteries, leaving in most cases abruptly.
The solution is simple. Replace the batteries and go, but if so we often find the second most common problem that usually give.
And this second problem is the frequency or lost sync with the receiver.
As we have said, normally this type of keyboard works by radio, through a receiver. Well, so they can communicate both must be tuned to the same frequency.
often work with a number of fixed frequencies and limited, so that system syncing is usually quite easy:
Both the receiver and the keyboard are a little button to change the frequency. This is press the button on the receiver and then press the keyboard until we match the frequencies.
Here if we can find a real fault, and this is has been damaged or the receiver or the sender of the keyboard, in which case there is usually no redress, much less at a cost that justifies the director.
In this category we can include wireless keyboards also new bluetooth keyboard.
These keyboards use this medium of communication with the PC, and have the same advantages keyboards via radio, most of it can be used in any device using a Bluetooth connection (and you have drivers for the keyboard), such as PDAs, some mobile phones, Tablet PC ... but also all its disadvantages, which must be added that in this case if you only work once the OS is loaded, and this in turn loaded the bluetooth drivers.
Well, so far we have seen different types of keyboards in order for your type of connection to the PC and the problems they can give. Now let's look at the generic problems that can occur in any type of keyboard, without having regard to the type of connection they use.
software problems:
The keyboard is a part not need driver, as it is supported by the device drivers the operating system.
While many multimedia keyboards have a CD or floppy disk with drivers, they are to activate some of the multimedia functions (not all, as many of them the supports Windows directory) and configure its use, not for the keyboard itself.
is not normal for this driver is damaged, but it is not impossible. In this case we will notify the operating system itself, and the solution is to recover this driver installation of the system. Usually recover deleted and letting the system re-detect the keyboard.
A common problem is that unconfigure. The solution to this problem is reconfigured as reloading the language and keyboard settings we use. This can be done from the Control Panel
and within this from Locale . Also
Control Panel, but in paragraph keyboard can set some options, such as the type of keyboard you use, repeat delay, repeat rate and cursor blink rate.
Windows keyboard settings.
Hardware Issues:
Well, the hardware problems that are motivated features a keyboard in the vast majority of cases for two reasons:
- Dirt that accumulates on it until it ends make it stop functioning properly and that is solved by cleaning, preferably with air.
- Misuse of the keyboard, due to shock and bludgeoning''.'' Although usually quite resistant keyboards are not unbreakable, so they end up giving up. In this case there is little basis except buy a new keyboard.
- Faulty keypad board, which is usually manifested by the malfunctioning of some keys. The arrangement is the same as in the case above, ie changing keyboard.
Ah, I forgot. There are three things in particular that they do not feel anything right on keyboards (and that is the cause of many faults:
Namely,
Coke and the like, coffee and beer .
On keyboards if there much difference in quality (and prices), and of course not the same brand keyboard (here we must make special mention of the brand
Cherry , although little known to many is the largest manufacturer of keyboards and one of the higher quality) and a certain price for a keyboard these economic (which is just over keyboards from 2.50 euros).
Among the top brands of keyboards can cite the aforementioned Cherry
, Logitech, NGS , Labtec , Genius and Benq , among others, to which we must add the keyboards houses of computers, which are usually of high quality, though sometimes hard to find, as is the case with HP , Acer, Packard Bell, Dell or Microsoft own.
Regarding quality, the palm is still carrying the Mechanics
keyboards, but have the disadvantage of not being very quiet. Keyboards Membrane have a quality getting better, are much quieter and significantly cheaper. That if good mechanical keyboard or hybrid (mechanical / diaphragm) is usually around 50 euros (not to be multimedia or anything).
Before closing I would like to clarify one thing. In many cases of failure, saying the solution is for a new one is on the ground that there is no market for keyboards parts and besides, unless we are''hands''and dare to try We repair, the cost of the repair work will in any case well above the cost of a new keyboard.
