Problem with toshiba laptop keyboard pressing wrong extra keys

Need to take the laptop apart and clean or replace the keyboard

Conflicting Extensions

Add-ons, also called plug-ins or extensions, are mini-applications that attach themselves to independent software and add extra capabilities to the program.

Extensions can change a browser's interface, alter the behavior of existing operations, add new functions or install in-browser support for programs like Shockwave Flash or Adobe Reader.

Because these extensions make changes to the overall operation of a browser, they can also affect the shortcut keys.

Most browsers offer an option to run the application with add-ons disabled; if the shortcut keys work when extensions are turned off, one of the add-ons is at fault.

Key Reassignments

Programs like MapKeyboard, SharpKeys and KeyTweak can reassign the functions of each key on the laptop keyboard.

If the computer is running a non standard keyboard layout, certain keys might not behave or respond normally.

For example, if the "Ctrl" key has been disabled or is set to work like "Shift," shortcut keys won't work as expected because the keyboard is no longer using its default mapping.

If the keyboard layout has been changed in the Dell laptop, the registry will contain a Scancode Map entry in

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout or the language bar will show a keyboard language different from the default ("English (United States)," or "EN," for Dell laptops purchased in the U.S.).

Virus Infection

Malicious software can affect the function of peripheral components like the keyboard and mouse.

If the keyboard is exhibiting strange behavior for example, if certain keys do not respond or if keys output unexpected letters a virus is most likely the cause.

Running an anti malware software from within Safe Mode accessed by pressing "F8" on the Dell logo screen should remove any viruses interfering with keyboard response.

Browser Software

Upgrading or downgrading a browser on the PC can affect the Internet shortcut keys associated with that program, especially if the version removes a function that was once associated with a particular keyboard combination.

Alternatively, if you've switched to another browser, you might find that certain shortcuts that worked in the previous browser don't work in the new one.

For example, while "Shift-F10" opens a context menu in Internet Explorer, the same keyboard combination does nothing in Mozilla Firefox.

Hope this helps.

There are various ways of solving this issue. Some of them has these broad explanation.

Problem #1 - My Laptop Keyboard Keys Not Working

Sometimes you may find certain keys of your laptop keyboard not 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 suppose to maintain your laptop keyboard by cleaning and lubricating it regularly.

Troubleshooting Steps

1. To start with, take out each key out from the laptop keyboard. 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.
2. 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.
3. 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.
4. 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.
5. 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.
6. Similar to the manner in which you lubricated the keys, apply mild lubricant on the keyboard surface and let it dry.
7. Once you have cleaned and lubricated all the parts, carefully reassemble the laptop 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 laptop keyboard in the above prescribed manner once a year, can prevent many 'laptop keyboard not working' situations.

Problem#2 - My Laptop Keyboard Types Wrong Characters

When your laptop keyboard types wrong characters, it is because of a software problem and not a hardware one. If you accidentally press specific keys on your keyboard, it can activate a particular function responsible for the problem.

Troubleshooting Steps

1. Select the control panel option
Click on ? 'Regional and Language Services' ? 'Languages' ? 'Details' ? 'Key Settings'
2. Choose the option 'Switch Between Input Languages' and click on 'Change Key Sequence'
3. Make sure that all the check boxes in the window are unchecked and repeat the same for 'Switch to..... (Keyboard Type)'
4. Click ?'Ok' ? 'Ok' ? 'Apply' ? 'Ok'.

Problem#3 - My Laptop Keyboard Types Numbers Instead of Letters

This is another laptop keyboard problem due to some software issue. It is possible you may have enabled a digital lock unknowingly.

Troubleshooting Steps

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

Num lock is on in your keyboard, just turn off the Num Lock by pressing the NumLock key on your keyboard

Fosg2000 Rate me please

hold down alt,ctrl, or function, then press your key.

hi.. is that a bi-lingual keyboard that you purchased? If so, what model? If that's a toshiba laptop w/ a bi-lingual keyboard, press the left (shift+ctrl) buttons for 10-15secs then release it. You should be able to bring back the normal function of your keyboard. If your having problems pressing the "n" key and it replaces it with a number on the screen when you type it, it's most likely that you enabled the "num lock" function of your keyboard, on Toshiba press FN+F11, on Dell FN+F11 also i think, it may differ on other models, sometimes FN+ Print Screen or Pause (above F11).

Hope this helps.

dear bangaloreboy , this may be due to your shift key is having a problem. This is permanently pressed or the other key is having some problem . If you think shift key is not causing a problem please check the key board settings from contol pannel .

I donot think this is caused by changing the operating system.

You need to clean the keyboard. Blow it with air blower so that the paricles inside keyboard will be eliminated. If not work, then you disassemble the keyboard and clean the key one by one. afraid to do , then let the repairman do it for you or you can attach USB keyboard for the laptop.

has it ever worked?
it could be that your are pressing the wrong combination buttons or that if its a laptop with a spanish keyboard, the keyboard settings is kind of wrong..

to check if its the keyboard settings, go to control panel and look for something that has to do with lenguaje.. there you can set up the lenguaje you want..

hope that helped..
