I presume you must have a laptop as a replacement desktop keyboard is really inexpensive. So each key on most laptop keyboards have a silicone or rubber cap under each key cap with a conductive pad inside that bridges and connects some contact points on the keyboard circuit board, when you press a key. So anywhere on the keyboard circuit board residue from say a beverage spill can conduct at various points and cause all sorts of strange keyboard behavior. So you could start by popping the non functioning key cap off of the keyboard and cleaning that key with a cloth and some isopropyl alcohol and maybe get a tiny bit of alcohol into the rubber key cap. You could remove all the keys and keep them in the precise order and try cleaning all the keys. By the way if your computers is very old, popping off the key cap can sometimes break the plastic parts from the plastic being brittle so be real gingerly and try not to break or even remove the underlying plastic hinged parts under the key cap Also understand assembling keyboard plastic parts and latching them back if they come loose can be quite tedious. If nothing works you can simply order a replacement keyboard from eBay by using your make and model of computer and changing keyboards is usually an easy job with a few screws underneath that hold the keyboard and you could watch a tutorial on YouTube on how to change the keyboard or find a friend or family member who is handy or just get a shop to do it and it probably would not cost a whole lot.
I would try cleaning your keyboard. If you are gentle you can remove the F10 key and check that they is no dirt underneath. Check other keys near the F10 key in case others have the same problem. I know that a sugary Cola spillage on a keyboard really sticks things up. In that case it was easiest to get a new keyboard.
Restore a Laptop Keyboard b> 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.
Click start control panel keyboard hardware make sure you have the right keyboard selected or you might have uninstall the keyboard then restart your computer then reinstall it and its drivers Click start control panel administrative tools computer management device manager scroll to keyboard you might see a yellow question /exclamation mark ? ! or a red X right click update driver if your computer came with a motherboard disk the drivers could be on it. If its still not working Tap the "Alt" and "Shift" keys simultaneously if you are pressing one keyboard key and getting a different symbol or letter. This will reset the keyboard defaults on some laptops. Press the "Ctrl" key and tap the "Shift" key simultaneously if the procedure in Step 1 did not work. Press the "Fn" and one of the "F" keys to disable the "Num Lock." Different laptops use different "F" keys to disable the "Num Lock." Toggle each "F" key and press the "Fn" key at the same time to find the right key combination. Check your laptop manual to find the right key combination. Press the "Fn" key and the blue "NumLock" key simultaneously if the keyboard is typing numbers instead of letters or wrong letter keys and the above steps did not solve the problem. b> Keyboard Maintenance b> Blow compressed air in the cracks and crevices of the laptop keyboard. Sometimes dust and debris can cause keys to lock, making such keys non-functional. Disconnect the laptop from the power outlet and remove the battery. Make the tip of a cotton swab as thin as possible by rolling it between your finger tips. Dip the thinned cotton swab in rubbing alcohol and clean the crevices of the keyboard with the cotton swab. Continue cleaning between each key of the keyboard with the alcohol-dipped cotton swab. Use a new cotton swab whenever necessary. Slightly tip up one side of the laptop so dust will move from under the keys to the crevices so you can clean. Blow compressed air into the keyboard again as you did in Step 1 of Section 2. Reconnect the computer to the power and check to see if the issue is resolved. Insert the flat edge of a flat-blade precision screwdriver under a keyboard key and gently pry it up and off. Remember where the keys go, so you can easily replace them. Remove three keys at a time and clean with a cotton swab dipped in alcohol. Replace the keys and remove the next three. Do this until the entire keyboard has been cleaned. Disconnect the laptop from the power outlet and remove the battery again. Turn the computer so the rear is facing you. Remove the screws that hold the plastic hinges in place. Insert a small flat-blade precision screwdriver in the plastic hinge seam and pry the hinges up. Turn the computer back face forward and open the screen as far back as it will go. Continue lifting the plastic hinge and power plate until it comes off. Remove the screws you see holding the keyboard with a precision Phillips screwdriver. Blow compressed air under the keyboard. Lift the cable connector levers slightly and remove the data cable. Clean the cable pins with an alcohol-dipped cotton swab. Replace everything, power on the computer and try the keyboard again to see if the issue is resolved. b> Keyboard Replacement b> Connect an external keyboard to the USB port on the laptop and verify its working condition. Disconnect the external keyboard and verify that the keys on the laptop are still inoperable. Disconnect the laptop from the power outlet and remove the battery. Remove the laptop keyboard as you did in Step 3 of Section 2 by removing the plastic hinge and power button plate, the keyboard screws and disconnecting the data cable from the motherboard connector. Replace the keyboard with a new laptop keyboard for your laptop make and model.
the keyboard is shorting. sounds to me like someone spilt something on the keyboard...
replacing the keyboard is the only thing that will fix this once this happens. Laptop kepboards are designed to be throw outs.
if this was a desktop i woudl say you coudl try cleaning the plastic boards but since it is a laptop you can get a replacement form ebay and usually decent priced.
OK try this. Get a can of air and spray down the keyboard real good and wait about 5 min. Then plug it back in and let me know how that goes. i done that to mine and it work on mine. because it's usually gets dirty and nobody thinks about cleaning it. Thank you for writing to fix ya.
Faulty keys on keyboards are very difficult to fix, usually you need to replace the keyboard.
You can try removing the key and if you can get to the rubber membrane switch you may be able to use a cotton bud with electronic cleaning fluid cleaner on the contacts. Replacing the key could be difficult with the small plastic hinge components.
If you are lucky place the key over the plastic hinge and pressing down till it clicks into place.
If it works you are in luck, if you are unlucky it may not work at all, then you need to buy a replacement keyboard or use a USB keyboard with your laptop.
