Try this unauthorised repair, pop the key top off make a small spitball and push it down the little hole in the hole and replace the the ket top. It should work. The proper repair is to replace the contact sheet. You need a tech for that.

How do I unlock the keyboard of IBM Selectric III???


The Selectric typewriter has several "interlocks" that can cause the keyboard to be locked. When you turn the machine off there is a mechanism that locks the keyboard. When you turn it on the part should move and unlock the keyboard. Sometimes this part sticks and the keyboard will remain locked. When you type any character the keyboard is locked to prevent two keys trying to type at the same time. The machine locks and unlocks very fast. One keys is locked in and prevents others from working. try turning on the machine and hitting every key just a little bit harder and see if it then types. When you shift, as the ball is turning the keyboard is locked temporarily so it won't attempt to type as the ball is turning as that would damage the machine. Sometimes the shift mechanism can cause the keyboard to remain licked as the shift may not have finished it's complete cycle. Also, the return mechanism locks the keyboard temporarily when the carrier is returning to prevent you from typing when the carrier is moving backwards. Only a qualified technician can resolve those issues.

My inspiron mini 1018 notebook's keyboard is not working properly. The left shift key appears to be stuck and I really having a hard time using the whole keyboard. I remember having spilled a few drops...


When water spills into a notebook, you should fully disassemble the notebook & thoroughly inspect its inside. Look for any traces of liquid on the circuit boards & on other components. On circuit boards, liquid damage appears in the form of whitish traces. These needs to be wiped off. This can be done using a tooth brush moistened with few drops of hand sanitizer liquid.
Check all internal connectors & make sure that no liquid seeped into them. Dry them if needed.
When you are done, re-assemble back the notebook.
If the liquid fell on the keyboard & you found out that the keyboard is no longer working, then you might have to replace the keyboard.

My nb100 laptop. keyboard some keys not working.


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
  2. Click on ? 'Regional and Language Services' ? 'Languages' ? 'Details' ? 'Key Settings'
  3. Choose the option 'Switch Between Input Languages' and click on 'Change Key Sequence'
  4. Make sure that all the check boxes in the window are unchecked and repeat the same for 'Switch to..... (Keyboard Type)'
  5. 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

Both of my shift keys stick in the "up" position,


Hi Brown551967,

Its the dust & dirt in the keyboard problem. If you have a powerful vacuum cleaner, try cleaning your keyboard with that. But before that use a long bristled brush between the keys to loosen out any stubborn dust particles. Concentrate more on the affected keys. If this helps the fine else you might need to disassemble the keyboard and do a thorough cleaning. Please DON'T try it if you're not confident of doing it. Just cleaning it thoroughly will do the job.

Hope this solves your problem.

Got liquid spill on lap top keyboard, lap top works fine,but some keys do not work, any suggestions!!!


Hi there,

Almost every laptop keyboard ever produced (or so it would seem) is available new as a part on eBay. It's where I buy all mine. SInce you don't mention the model of laptop here, just got to ebay's main page and in the search box type your laptop model followed by the word "keyboard". Most of them there are around $10 while others range up to $25.

Keyboards are usually just about the quickest and easiest part to replace on a laptop.

Best Regards,

Marcus

BTC MDL# 6300CL Illuminated, (NOT wireless), keyboard. "S" key no longer seems to be making contact. Mechanically keystroke still feels same as all the rest. I really love this kybd & would hate to...


Carefully stick a butter knife tip from the bottom side of the key.
e.g. Above the Z and X key.

Turn very carefully either clockwise or counter clockwise (it doesn't matter) either way do it carefully until you hear a little click, the key will pop out and you can clean it.

To reinstall just center it, and "carefully" press down till you hear it snap back in place.

There's little ***** plastic tips which snap together, if you snap one off your toast.

I learned this because I have TWO BTC 6300CL's and I used the keys from one on the other, and have since removed every key "carefully" and cleaned it and re-assembled it and it works a treat!

Good luck, these are really hard to find now.

KEY BOARD DOSNT WORK PROPERLY


Take the back panel off by undoing the screws ,then un-clip the keyboard & under it you will see a ribbon cable going to the main board theirs two little clips on both sides where it joins, lift them up with your finger nails then push the ribbon in untill it's straight & all the pins are back in then clip it back down.test it before you put it back together.
other than that clean under the buttons with some contact cleaner & a cotton bud..
GOOD LUCK........
