HP Notebook PCs Notebook Keyboard Troubleshooting Windows 7

You must increase the leadtime before Windows considers your keeping a key pressed down means you want to repeat it.
Open Keyboard Properties by clicking the Start button , and then clicking Control Panel. In the search box, type keyboard, and then click Keyboard.
Under Character repeat, move the Repeat delay slider to the right to increase how long you must hold down a key before the keyboard character repeats, and then click OK.

Step 1:
Locate the Fn (Function) key on your keyboard. It may be on the bottom left side with dark blue letters. Locate the two "brightness" keys near the top of the keyboard. These will be in the "F" keys, possibly if F6 and F7. They should have little sun pictures or something similar to indicate brightness. Hold down the Fn key while pressing F7, or whichever "F" key your laptop uses to increase brightness. Tap F7 repeatedly until you reach the desired brightness. Fn must be held down as you continue to tap.

If you mean the laptop keyboard and Touchpad are not working ?
the problem might be caused by the same issue for both.

Laptop keyboard and keypad not working

Laptop keyboards are a little more delicate than keyboards used in desktop computers. Hence they face more problems.

Normally, they are replaced when they render defective. However, most of these keyboard issues can be taken care of or even prevented by regular cleaning.

Common issues like, keys not working on your keyboard, having to press keys firmly to get the output or any keyboard typing issues, can easily be handled at home.


Sometimes you may find certain keys of your laptop's keyboard to not be working properly. You type those keys but there is no output on the screen or you need to press these keys firmly to get a result.

You face this problem if you accidentally spill any liquid substance on your keyboard, or due to dust accumulating on the inside of the keys, pressing certain keys really hard while playing games or even due to absence of lubrication.

Therefore you are supposed to maintain your laptop's keyboard by cleaning and lubricating it regularly.

Troubleshooting Steps

Locate the "Fn" key in the lower right or left corner of the laptop keyboard.

The "Fn" key typically has different colored text on it or the key itself is a different color.

Locate the function (F1 through F12) key at the top of the keyboard that disables or enables the touchpad on the laptop.

To start with, take out each key. Use a small screwdriver to carefully pry each key by making it loose.

As they become loose, keys will simply pop off.

Also, take out the rubber piece present under every key. Keep the keys and rubber pieces in different containers.

Once you have removed all keys from the keyboard, you will have to clean the keyboard from the inside. Use cotton swabs or ear bubs and slightly dip them in water.

Avoid getting them too moist, as excess water can damage the keyboard. Meticulously clean the whole keyboard using moist cotton swabs, laying extra emphasis on key spaces.

Now, start cleaning keys you had earlier removed and kept in the container. Use foam rubber and lighter fluid to clean each key alone.

This will help in removing any sticky substance present on keys. Apply any household cleaner on these keys and let them stay for about 15 minutes. After this, wash all the keys properly using hot water and let the keys dry completely.

The small rubber pieces which you took out earlier and kept in the container have to be thoroughly rinsed in warm water, after you have sprayed a household cleaner on them. Soak these rubber pieces up in paper napkins so that they dry quickly.

To lubricate the keys, place all keys (facing top-down) on a flat surface. Apply mild lubricant from all sides, on all keys and leave them to dry. Avoid applying too much lubricant instead go for a light coat.

Similar to the manner in which you lubricated the keys, apply mild lubricant on the keyboard surface and let it dry.

Once you have cleaned and lubricated all the parts, carefully reassemble the keyboard. Begin with placing all rubber components on the keyboard.

Next, fix all keys in their respective positions cautiously securing the wire in these keys. Use your finger and press down all keys, one at a time, firmly so that they fit properly in the slots. That is it.

The complete process will take you a maximum of 2 hours. Cleaning and lubricating the keyboard in the above prescribed manner once a year, can prevent many such situations.

Pressing the 'Function' key along with the 'Num lock' key (Fn + Numlock) or press the 'Function' Key along with the 'Shift' and 'Num Lock' key (Fn +Shift + NumLock). This will disable the lock and consequently solve your problem.

This was all about solving your laptop keyboard problems that you can try out yourself. After trying all the above given options, if you still find the keyboard still not working, you will have to take your laptop to a service center to get it repaired

Touchpad Not Working in Laptop

Most modern laptops come with a touchpad mouse built into the computer.

If you've tried to use the touchpad and the mouse pointer on screen is unresponsive, chances are that you or someone else has accidentally disabled the touchpad using one of the Function keys on the computer.

To fix an unresponsive touchpad on your laptop, reactivate it using the Function key on the keyboard.

This process is different for each computer manufacturer.

Locate the "Fn" key in the lower right or left corner of the laptop keyboard.

The "Fn" key typically has different colored text on it or the key itself is a different color.

Locate the function (F1 through F12) key at the top of the keyboard that disables or enables the touchpad on the laptop.

The key typically has an icon that resembles a touchpad with a finger touching it or a touchpad with a diagonal line through it.

Press both the "Fn" and touchpad Function key simultaneously to reactive the touchpad on your laptop.

Move your finger along the touchpad to verify that it works.

Press the combination at any time to disable the touchpad again.

Hope this helps

Physically sticky keys because you spilled something on them or sticky keys keyboard shortcuts?
The first you don't really unless you want to dismantle the keyboard and clean the entire thing (do-able but it would take you a long time and you risk breaking the pieces under each key) I would just buy a new keyboard on ebay for $15-30 and have someone replace it.
Second, keyboard short cuts you can disable under Control Panel > Ease of Use > "Make the keyboard easier to use" and uncheck sticky keys.

Comment if you need more assistance and please rate the solution if you found it useful.
Thanks,
Justin

You have 2 Shift keys on the keyboard. If the other shift key is working then the shift key that is not working is defective. You should consider replacing the keyboard on your laptop. There is no setting on Windows that can disable the shift key.

**Note : If both Shift keys are not working, Try to check if sticky keys feature on windows is on. Sticky keys should be disabled. To disable sticky keys, Click on start and Go into control panel > Accessibility Options, and under keyboard there is sticky keys. Remove the tick and click apply and OK.



**If "Use Sticky Keys" is unchecked, that means sticky keys is disabled.

Hi,

I think filter or sticky keys enabled.
Go to Accessibility options in control panel and disable it.

Hope this helps.

Go to Control Panel >
Accessibility Options and turn off the Filter Keys option. Also click the
Settings button for it and disable the shortcut (by default, holding down
the right Shift key for 8 seconds turns it on). You should probably disable
the other two accessibility options, too, to avoid unpleasant surprises.

try to press the key using screw driver or any pin that you can press into the keyboard..but remove first the top key..try pressing with some screw if its typing,if not its mean the logic board is damage and you need toreplace a new one...if working with the screw pressing..repalace with a key button only with the same lock.

Disable scroll lock, caps lock in bios, this enable lower case keys on the keyboard, thus not right key asigns. Or if drink is spilled on keyboard....replace keyboard JJ
