Keyboard Failure due to Moisture

I have a customer with a laptop keyboard that got wet.  Now the ~34QEDZC keys will not work, and the Z key is continually stuck.  I have tried the drying out in the sun method mentioned in this forum with no success.


What I need now:  How do I remove/replace this keyboard?  I am a network engineer and electronics tech, so I am no stranger to intricate repairs.  I just can't seem to figure out how this thing comes apart, and wanted to get a step by step how to for this model.


I have already found a replacement, but did not want to order it until I had the old one removed.  Thanks in advance for the help.

Re: Keyboard Failure due to Moisture

There are four screws that need to be removed, two under the battery (not the one closest to the edge of the Notebook), and two at the rear end at the hinges. The two at the hinges have a small cover over them held in place by adhesive, just lift them off with a sharp object. Removal of these screws now enables you to remove the cover between the keyboard and screen, also covering the hinges. Once this has been removed, there are two slides on the keyboard, one between the 'esc' and 'F1' keys, and one between the 'Ins' and 'Del' keys. Simply use a small flat blade screwdriver to slide each block towards the '1' and 'Backspace' keys respectively. The keyboard can now be lifted (carefully) and pulled away. To unclip the ribbon cable, carefully lift the clip over the ribbon cable - it is hinged. Replace the keyboard and reverse the procedure to fix it in place.

Re: Keyboard Failure due to Moisture

As you have done, and I would suggest to anyone with the same problem, just replace the keyboard. You can get them quite cheap and in used working condition from some of the online auction sites.


Most of the Acers laptops will have a couple of screws on the bottom that hold the keyboard in, possibly. Will also need to remove the hinge/power button cover between the keyboard and the lcd. Might have some screws holding it in from the bottom, might not, also check under the battery at the back for any hidden screws. It may simply pop off and on... then you'll possibly find two screws under that holding the keyboard in. Once the screws are out, simply lift it slightly to find where the ribbon cable plugs in. And gently lift the locking latch on the keyboard plug. The ribbon will then easily slide out. And simply do the reverse to install the new one, making sure to push that plug lock back down.


This is just a generic assumption, as I am not real real familiar with the 5570, but they are all alot alike. Also note, when removing the power button cover, just in case there may be a ribbon cable under it attatching it to the mainboard, if you pop it off, look under it before pulling it too far. Wouldn't want to rip a cable if there is one there.

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

Keyboard got wet several keys won't work....what can i try?

Find a container large enough for the device and remove its battery. Place the device in the container and cover it with dry rice overnight. The rice will absorb the moisture. You may need to use compressed air to get any grains of rice out of keyboard and other crevices.

Spilled water on keyboard. a few keys don't work

If this problem occurred recently you might still be able to save the keyboard. However, it is a painstaking method of popping out each of the keys that are not working and cleaning them off (preferably with some contact cleaner) and making sure that there is no corrosion trying to form due to the moisture. Be careful when prying up some keys as some keyboards (especially laptop keyboards) are hard to put back if you don't have the right tools or the know how. I suggest looking up keyboard removal techniques based on the brand of your keyboard/laptop.
Good luck...

My keyboard is glitchy.

If you don't want to buy a new keyboard, you can open your keyboard and leave it to dry for a couple of days. There's still some moisture in the keyboard that's why this is happening. As soon as all moisture has been removed from the keyboard, it should work fine. But there's no guarantee since the board might have short circuited already.

Water spill on keyboard

normally what I recommend to do first is open up and take Motherboard out and blow it with hair dryer and expose it to sun for 6 hours(wholeday) to let it dry properly ...coz with every of my customer who don't do but claim that computer work fine will soon have problem in future due to oxide (coz under some IC or chips its still wet and it takes time to become oxide and when it does that mean short circuit).So
Incase anymore question you can post here.

Half of keyboard does not work

did you by chance have a drop of liquid drop ontot he keyboard...such localized keyboard failure usually indicated moisture has gotten tot he dielectric material...I would suggest to place your computer screen up, keyboard in direct sunlight for about an hour a towel over the screen as not to damage it...and let the sun's radiant energy promote the moisture fromthe keyboard ,,,also do not turn machine on again until removed from sunlight, and allowed to cool for about 90 minutes...
