Keyboard not working...

When a keyboard stops working, has odd key letters, stuck keys and non-functioning keys for no reason at all, the laptop may have an easy fix solution. However, if liquid spilled on the laptop or the laptop was dropped and as, a consequence, the keyboard doesn't work, or the keyboard device has simply failed, fixing the problem may require a more involved laptop keyboard replacement.

Although having a laptop is certainly convenient, the all-in-one peripheral scheme (mouse, keyboard and speakers) can make individual repairs difficult, and a non-working keyboard can ruin the value of the entire package. However, there are some practical steps you can take to fix a laptop keyboard.

1.Diagnose the problem. When you press a key on your laptop keyboard, does it get stuck? Does the computer respond to your inputs? In almost all of these cases, the solution will lie in opening up your notebook's keyboard. However, to prevent extra work, press every key (do this in a word-processing program) and see which keys are affected. If every single key on a keyboard does not respond, you might have a software issue, which may require specialized help.
2.Clean the area around the keys that are not working. A damp lint-free cloth should be used to clean the surface of the affected keys. If you have stuck keys, use a Q-tip to clean under them, but take care not to pry the keys up, as this could result in further damage to your keyboard.
3.Remove the keys that are not working. Do this by grabbing some fingernail clippers and pulling out the hook-like fingernail cleaner extension. Use the small hook to gently pull the key up , which will expose a collapsible plastic hinge (commonly known as a key retainer) as well as a small rubber circular piece. Gently lift both of these pieces out of the keyboard.
4.Wipe the keyboard sensors clean with a dry cloth. The sensors are the little silver foil-like strips you see after your key components have been removed. Be very careful wiping these down--if they are damaged, they are very expensive to replace. Just gently dab it with a dry lint-free cloth to remove any dust/crumbs/particles that are interfering with your keyboard's functionality. Do not moisten the cloth with water or cleaning solution, as this heightens the risk for damage.
5.Reassemble and replace the keys. Simply fit the key retainer as well the little rubber piece together in the way you found them and then firmly press the key cap back in place.
6.Test your keyboard. Open a word-processing program and then press the replaced keys. If they still don't work, try restarting your computer, or activating a system restore point (to ensure that the problem is not software-related). If the keyboard is still not working, then you may want to think about taking the computer to a repair shop or replacing it altogether. (Keyboard repairs are very expensive.)

I hope you find it very helpful. Thanks.

Hi,

First try changing the batteries, reconnect the dongle or the connection device of your wireless keyboard and mouse, then restart your computer. If the step wont work reinstall the Bluetooth/Infrared software driver the wireless keyboard and mouse then restart the computer. If this fails still look under Ad/Remove programs if you have a Setpoint installed then remove it and restart computer, both or at least one of the devices should work. If one or both wont work then you need to contact the manufacturer and have the defective device/s be replaced. Just a heads up, they may ask you to reinstall your operating system / do a reformat of your computer so you need to back up your data ahead of time using a wired keyboard and mouse. Have a nice day ahead!

Hi. Please do troubleshooting steps below:

1. Check to be sure your "Number Lock" or "Function Lock" keys aren't lit. These can lock out certain parts of your keyboard. If either of these is lit, press them to unlock the locked portion of your keyboard. These can be found at the top right on a laptop and between the number pad and main keys on a desktop keyboard.

2. Save all open programs using your mouse. Use your mouse to restart your computer. This will only work if your computer isn't frozen. If your mouse doesn't move, press the power button on your Dell until the computer turns off. Press it again to restart. If the issue was lack of memory or a locked program, this will unlock your keyboard. Continue to Step 3 if the keyboard is still locked.

3. Shut down your computer using your mouse or power button. Don't restart. Unplug your Dell.

4. Remove the battery if you're using a laptop by turning the laptop over and sliding the battery release latch. Slide the battery out and replace after one minute.

Have a good one!

Step 2 Save all open programs using your mouse. Use your mouse to restart your computer. This will only work if your computer isn't frozen. If your mouse doesn't move, press the power button on your Dell until the computer turns off. Press it again to restart. If the issue was lack of memory or a locked program, this will unlock your keyboard. Continue to Step 3 if the keyboard is still locked.

Step 3 Shut down your computer using your mouse or power button. Don't restart. Unplug your Dell.

Step 4 Remove the battery if you're using a laptop by turning the laptop over and sliding the battery release latch. Slide the battery out and replace after one minute.

Hi,
Your problem may be due to the sleep button in your keyboard may got struct into when you cleaned your keyboard.
Try to resolve the struct in the keys, if any.
Restart your system and if still your problem persists, then remove your keyboard and restart your computer and try with some other keyboard if possible. Once if you find out that the problem is with your keyboard, then replace the keyboard / service the existing one.'

I hope this is helpful to you. Please provide your ratings.
Thanks

Did you spill something on it or is food lodged in unit if so take apart clean.
Fresh batteries would be good start.

Solution. My wireles keyboard stopped working except for the F-Lock key, the Media key and the sleep key. It wasn't batteries, even though I tried, communication was there because the above keys were working. Remove the batteries from your keyboard and let it sit for about 10 minutes. Press the red connect button a few times and other various keys every few minutes during that time. This may be the whole "capacitor discharge" trick, but I tired that with someone elses instructions and my keyboard did not work after 2 minutes of key pressing. I think it just needed more time to clear out the secure settings. Good luck, I was about to trash this keyboard until I tried again

You need to reset the keyboard by turning it over and pressing on the reset button. If it still doesn't work, press on the receiver button then press the button on the back of the keyboard. It resets and connects the keyboard to the system. Hope that will fix it. Bud
