|
|
We often came across this case: the keyboard is out of control. It’s not serious to many people because it can be repaired by hand. Some laptop users are quite good at handling it. Thus, for some one, they have no idea of how to fix it. This phenomenon is due to the circuit board has loose connection with the conductive plastic. Or, the keyboard plug is damaged. The CPU is not working properly. These are not the main reasons. As this Compaq NX6115 Keyboard, I will show you how to fix the keyboard through this case. When you encounter this problem, the first thing you will do is to open the keyboard to check the under part. This step should be really careful as there are plastic circuits under the key caps. Otherwise, you will have you keyboard in trouble. It’s half done when you open the keyboard properly. Then you can figure out the reason of the situation. Like dell D520 OPF236 Keyboard, dell 9300 US Keyboard, and Toshiba 6037B0001401 Keyboard, the circuit boards are usually made of soft plastics film, engraved key cable. It’s preferred to use high concentration alcohol to gently scrub two times of the circuit board, especially those parts that work not so properly. This way the dust can be wiped off. So this only helps to clean the dust. If the circuit is broken, this will have no sense. We have to take it to the service center to change new circuit. At the mean while, we can have the inside part a thorough cleaning. As we seldom open the keyboard, it’s better to clean the inside. We should try this step in tender for it’s vulnerable components. This is the solution to have the key coming under your control. This is usually caused by the dust blocking or the broken circuit lines. So we can solve it by our hands. This HP 407857-001 Keyboard is not so easy to handle for it is caused by the CPU problem. Then I have to send it back to the company to repair it. _________________ My store: laptopskeyboard.com |
