How can you adjust the sensitivity of the keys on a laptop keyboard? Or you're really frustrated by your new laptop like an old typewriter. Is there any way to adjust keyboard sensitivity, or what? Don't worry, this guide will help you on the go.
Windows controls how long you must hold down a key before it repeats, along with the key repeat speed. If characters repeat too quickly or slowly when you hold down a key, open the Control Panel and then open the Keyboard entry. Choose the Speed tab and move the sliders for Repeat Delay and Repeat Rate until you've adjusted them to your style. The Repeat Delay slider determines how long you must hold down a key before it begins repeating, and the Repeat Rate determines how quickly repeated characters appear on-screen. Click Apply when you're finished.
Besides, the design of some notebooks allows your hand to graze over the touchpad for the mouse, causing it to pick up the mouse movement and sometimes sacrifice the key stroke.
The other possibility is that either something is under the keys, causing them to not to make the proper contact when pressed. Get a can of compressed air (Wal-mart sells these in the computer section) and blow it in short bursts along each row of keys.
Then, there could be something corrupted in the keyboard driver. This part assumes you are using Windows XP. Click on Start and then right-click on My Computer. Select properties. Then select the Hardware tab and select Device Manager. Once in Device Manager, click on the + next to keyboards. Likely there will be only one option, but if there is more than one, select the one for you keyboard and right-click on it. Click on Uninstall. Then reboot your computer. As the computer restarts, it will recognize the keyboard and reinstall the driver, but hopefully this time it won't be corrupted.
Finally, sometimes your laptop keyboard could be more sensitive. Most keyboards these days, especially on laptops use flexible membranes as their contacts. There are two primary methods of manufacture, one utilizes a standard PC board and a rubber mat with carbon pads in the rubber. The other utilizes a flexible plastic (like DuPonts Kapton) with a layer of contacts, a spacer, and another layer of contacts. Both then put the plastic frame for the keys on top. The keys have small springs which just keep the key up, not affecting sensitivity and a shaft down the middle. The shaft then presses on the rubber pad or flexible film beneath. The actual sensitivity is based on the durometer (hardness) of the rubber or the thickness of the Kapton.
The only practical solutions would be:
1. Replace the keyboard. A new keyboard is usualy less sensitive though.
2. Tighten the fasteners inside. If the laptop is an older one you may try opening the unit up and tightening the screws that hold the keyboard up to the key frame.
Other than that you are looking at a custom designed short run membrane. It is cheaper to get a new laptop keyboard in that case. Papatek.com compatible laptop keyboard is your good choice.
