    Non functioning? If it's an older laptop, there may be a lot of grime and **** underneath the keyboard which may be stopping it recieving the key in which you press. Possible solution, either you or if you don't feel comfortable in doing so, to lift the keyboard out. Usually around the top, there are 2 areas where you lift it up and out. I suggest you Google your Laptop model, and read the users manual of how to do that safely. Now, if it is not an actual Hard Ware issue, it will be relating to a function set, or a lock of some sort which has been activated. If you would like more assistance, please provide more to detail as to what keys, at what time they stopped working, and anything you've done recently that you think possibly might have affected the keys. Help I may have been helpful in some way!

SOURCE: non-functioning keys toshiba equium keyboard m40x 149

Have you tried connecting a regular desktop keyboard to your laptop? If so, does the same thing happen?

Keyboards do develop problems, and can usually be fixed by replacing the keyboard. It's not necessarily a virus (actually highly unlikely).

SOURCE: keyboard keys non functional

I spilled a little water on my keyboard as well.Just a few drops not much but the keyboard stopped working , some of the keys at least.I bought a new keyboard from the Internet and it works like a charm now.
They have pretty good install pictures on this site.I watched the pictures and replaced the keyboard myself.It took me no more than 20 min.I payed something like 20-30 bucks for the keyboard.

PS
I called a shop here in Vegas and they were asking 75 just to "diagnose the problem".

Scan for Viruses

Sudden, unexplained computer issues are commonly caused by a virus infestation. These sneaky programs secretly install themselves on your system and alter the way the machine functions and responds to commands. Eliminate any hidden malicious programs by running a deep scan to find and destroy unwanted programs. You may need to perform a restore or recovery action on your system afterward to replace corrupted files with the correct versions.
Troubleshooting

To determine whether your non-functioning F5 key is due to a software issue or faulty hardware, connect a separate keyboard to your Pavilion. If the F5 key works on the external keyboard, the problem with your Pavilion's F5 key could be physical, such as a dirty key or spilled liquid. If the F5 key does not work on the external keyboard either, the problem likely lies in the software. Make sure that your operating system files are up-to-date to encourage proper communication between the keyboard and motherboard.

Thorough Cleaning

A keyboard key can become non-functional if it cannot make contact with the proper sensor beneath it, such as from accumulated debris or a spilled liquid. Dust, hair and lint can collect beneath and between your Pavilion's keys, which can interfere with proper contact when the layer becomes too thick. Sticky residue left behind by sugary liquids, such as soda or juice, can cause the key to stick, preventing the computer from registering the press. Thoroughly clean the area beneath the F5 key by gently prying the key off and using a cotton swab and rubbing alcohol to remove any dirt or residue.
Safe Mode

When you start your Pavilion, numerous other programs automatically start with it. Any of these programs could cause the F5 key to become non-responsive. Starting the Pavilion in Safe Mode will load only the essential operating system files and drivers, and if the F5 key works while in this mode, your problem most likely lies with an installed program or hardware device. To enter Safe Mode, restart your laptop and press the F8 key immediately. You'll enter the "Advanced Boot Options" menu, where you can use your arrow keys to select "Safe Mode" and press "Enter." If your F5 key still does not work, you may have a problem with your operating system files.

My keyboard works except some keys are not working?


Your question is not specific about specifically which keys work and which keys do not work and exactly what you mean by the keys not working, whether you mean there is no reaction at all when the relevant keys are pressed or whether it is just that incorrect characters result from pressing these keys.

If incorrect characters result from pressing certain keys towards the right of the keyboard, use the Fn key, bottom left, pressed simultaneously with the Num Lock key, top right, to toggle 'on' or toggle 'off' the Alternative Symbol function of some of the multi-function keys.

If there is no reaction at all when you press a significant number of keys, then there may have been liquid spillage damage to the NetBook. Liquid spillage damage can sometimes be resolved by partial disassembly of a NetBook/Notebook and wiping congealed liquids off with mild solvent or allowing internalized water to evaporate. This type of repair is best done by an experienced NetBook/Notebook repair center or technician.

If only one or two or a small number of keys do not work, then it might be that particles of some or other substance, trapped underneath the keys might be interfering with the function of the non-functioning keys. This can sometimes be resolved simply by inverting and gently shaking the NetBookso that any trapped particles come loose and fall out. Occasionally, individual key caps have to be removed and replaced after the obstructing particle has been removed.

If several keys are defective but the fault was not caused by liquid spillage or trapped particles, then the keyboard unit itself might be faulty and need to have its internal ribbon cable and cable connectors tested for cable damage or connector damage (typically either from liquid spillage, shock caused by dropping the computer or by previous unprofessional internal repairs). If no fault is found with the cable or the cable connectors, then the entire keyboard unit may have to be replaced.

Function keys don't work as assignment on each key


Please mention whether you are using Notebook or a Desktop Computer. If it is Notebook please let me know the make of the Notebook as there will be a driver for the Function Keys to work. If it is desktop computer try using another keyboard to confirm if the issue is related to hardware of the Keyboard. For both the Wireless Keyboard of the Desktop and Notebook Keyboard it is required to press the Fn Key and the Function Keys (F1 to F12) together in order work.

Some keyboard button not workin on dell laptop


Did you spill any liquids into the keyboard? If you did you may have damage the keyboard PCB and it will need to be replaced. One thing you can try to do is to first take a picture of the keyboard so you know where the keys go back to that you removed. Then use a small screwdriver to remove the non-functioning keys. Be very careful and do not use too much force or you may damage the key. Inspect the inner buttons and see if they are sticking. You can use a cotton swab or q-tip and rubbing alchohol to try and clean the inner part of the keyboard. Sticky liquids can cause the inner keyboard buttons to stick and mal-function. If the keyboard PCB is damaged you can either replace the keyboard or buy a usb keyboard to use on the laptop. The OS should recognize the keyboard after you plug it in.

My son's toshiba Satellite L305-S5933 keyboard has just developed some non-functioning keys. Several just don't work any longer. No spillage.


No spillage, has the computer been dropped? the saudering under the key itself may have separated from the button itself. Try a can of 'air' and clean out any loose matter that may be between the keys in the keyboard first. Then if it's still not functioning, try lifting off the key button (one at a time) to see if you can see the direct connection and verify if its still connected. Try the air first. hope this helps.

F keys suddenly not working


The "F mode" button toggles on and off the F keys. If you press it (accidentally) as I did, the keys will no longer function.

Simply press the "F mode" key again (it is directly above the "End->" key between F12 and Insert on this model keyboard) and functionality will be restored.
