Laptop owners often encounter malfunctioning keys. Computer repair experts confirm that quite a few customers complain that the keyboard on the laptop does not work. What to do, why it broke and can it be handled independently?
There may be several reasons for this, from factory defects to improper use. In some cases, you can do it yourself, and in others you can’t avoid going to a service center or repair shop.
Manufacturing defect
It is possible that I blame everything on poor-quality parts or factory defects if the keyboard on the laptop does not work . What to do? In this situation, you should not try to do anything yourself, you just need to take the device to a service center. Without any consequences, the defect will be removed under warranty.
Wear during operation and carelessness in use
The laptop keyboard is subjected to heavy loads from numerous and sometimes sharp clicks, as well as the result of heavy objects falling on it. Thus, it can be damaged mechanically: the keys come off, sink, crack. In some cases, you can replace individual buttons if you can find exactly the same keyboard. If the mounting is broken, this cannot be done, and then you will have to change everything or buy a separate one and connect it via the USB port.
Often liquids are spilled on the keys: tea, juice, coffee, wine, beer, soda, and then the keyboard on the laptop does not work. What to do? The most favorable option if it was clear water or unsweetened tea. You need to quickly turn off the device, unplug the cord from the outlet and remove the battery. Turn the laptop over and put the open house in place so that the liquid is glass. Let it dry for a day.
If other drinks, especially sweet ones, were spilled, you will have to disassemble the laptop. Remove the keyboard, rinse with clean water and dry thoroughly. Check for liquid on the motherboard, pat it dry with a dry cloth. Some will be able to do it themselves, while others will have no choice but to call a professional for help. In the case of sugar-containing drinks, the keyboard is often not saved, and then its replacement is needed.
Sometimes the keyboard on the laptop is buggy, that is, only part of the keys do not work, or when you press one, two or more are triggered. This usually occurs when dust or other debris enters. After removing the dirt, the problem disappears. First use the blowdown method. If it does not help, you will have to disassemble the laptop and clean it. Such problems may be due to rupture of the conductive paths, which are oxidized by moisture. In this situation, experts recommend buying conductive paint or glue and drawing damaged tracks.
If the keyboard on the laptop suddenly crashes and completely does not work, what should I do? This happens when the motherboard malfunctions. Most likely, the south bridge burned down , which is responsible for the operation of the keyboard, touchpad, and USB ports. In this case, it is necessary to repair the system board in a workshop or service center.
It happens that the touchpad and ports are normal, but the buttons do not work. Most likely, the keyboard cable is damaged or disconnected from the motherboard. To repair or replace it, it is most advisable to contact the after-sales service.
When attempting to troubleshoot on your own, it is important to know that laptops of different brands can be disassembled differently.
Software issues
If I blame everything for the software, say, a crash in the operating system, it doesn’t matter if the keyboard on the Asus laptop or on any other brand of device does not work. Checking the cause is very easy: download the laptop from the LiveCD. If the buttons work, reinstalling the OS is required.
