How does HP Laptop Keyboard 441541-001 work

Keyboard is the most widely used computer input devices, which consist of keys, conductive plastics, as well as the encoder interface circuits so on.

On the keyboard usually has hundreds of buttons, each button is responsible for a function, when the user presses one, the keyboard encoder can quickly this button corresponding to the code transmitted to the computer through the interface circuit in the keyboard buffer by the CPU for recognition processing. In layman's terms that is, when the user presses a button, it will be the circuit board through the conductive plastic cable connected to this key generated signal, the signal generated by the keyboard interface, quickly sent to the CPU.

"Keyboard key failure" Trouble Shooting

"Keyboard key failure" This is what we often encounter problems. This phenomenon usually occurs because the circuit board or a conductive plastic on the dirt, making between the two can not be properly connected. Other factors may also be, for example: the keyboard plug is damaged, circuit problems, damage to the motherboard, CPU is not working properly and so on, but not the main reason. Therefore, we only need to carry out descaling their work.

Take HP Laptop Keyboard 441541-001 as an example, operation steps are as follows:
1. Disassemble the keyboard. Note that when you open the keyboard, be sure to button surface (that is, our operations side) down, circuit board up, otherwise, each key on the conductive plastic may have come off, giving you repair trouble.

2. Opening circuit boards, circuit boards are generally made of soft plastic film, the top row of buttons marked with lines, with the concentration of alcohol, preferably more than 97% of cotton (75% of medical alcohol can also be cotton, because I had used , but the best is to use high concentrations of alcohol, cotton) and gently scrub two times in the circuit board. Key part of the line for the failure to take care of several times more.

3. View key failure part of the conductive plastic, if the above accumulated a lot of dirt, the same use of alcohol scrub. Suppose conductive plastic is damaged, then I suggest that you can not key on the commonly used conductive plastic for the damaged part, although this initiative not allow the keyboard to play out all functions, but the most at least it can extend the life of commonly used keys.

4. Remove the keyboard in a corner in the dirt, tools can be a brush, small brush and so on, but note that some action should be gentle.

5. See the module whether the cold solder joint or Sealing-off welding can be carried out repair welding work (using tools such as conductive silver paint, concrete repairs please refer to the next section notebook keyboard repair examples).

6. Install a good keyboard. It should be noted here that we have to wait and then to clean the alcohol evaporates.

on my laptop my keyboard keeps skipping to the middle of another word how do i stop it or repair it? its so annoying i cant take it anymore!!!

please if anyone can help please do
hi everyone heres the thing it happens when i dont even touch the thouch pad lol im no where near it

for everyone's answers so far thanks!

I suspect your touchpad is so sensitive that it's picking up your hands as they move over it even without them touching it. Look around for a way to turn off or reduce the sensitivity of the touchpad.

I've been told, although I don't have a laptop to try it on, that you can do this:

In Windows XP:

1.Right-click My Computer and select Properties.
2.Click the Hardware tab.
3.Click the Device Manager button.
4.Find Touchpad in the list. (May be inside Mice and other pointing devices.)
5.Expand it, right-click on it and Disable it (Don't Uninstall it!)

In Windows Vista (possible Windows 7 too)

1.Right-click Computer and select Properties.
2.Click the Hardware tab.
3.Click the Device Manager link on the left.
4.Continue as in Step 4, above.

Hope that helps.
