All numeric keys not working


Check the settings in the BIOS to see if they are disabled. If the are not, use a portable keyboard to see if the number keys work. If they do, check the device manager to see what the keyboard is listed as. You can delete it from the list and have it redetected. IF that does not work, OEM says that you restore the computer to factory settings. If that fails then you replace the keyboard.

sorry but even a small amount of liquid can work its way under the keys. you could try getting a can of compressed air to dissipate the liquid that has seeped under the keys, if not then you will need a new keyboard or take the keyboard apart

Keyboard won't stop repeating the hyphen/underscore key.


Hey,

You have few solutions to this

  1. disconnect the keyboard flex cable from the motherboard so the keyboard is not connected at all.
  2. replace the keyboard
On option 1 you would need to take the laptop apart from the top so that you can take the keyboard out so that you can disconnect the cable, then place it back in.


On option 2 you would also need to take the laptop apart / open it from the top to get the keyboard out and disconnect the cable. and replace it with a new keyboard.

Look around ebay for the correct keyboard for your model, here is a ebay listing for acer laptop keyboards

Thanks and good luck.

Keyboard problem


You just need a new keyboard - those are easy to come by check ebay.com and search for C640 keyboard. New ones should only be about $30-$40.

To remove the keyboard you just remove all the screws on the bottom of the laptop that are marked with the letter "K" then carefully pop the keyboard up.

This is a rather old question, but the solution might still be helpful to other readers.

I suggest you call Tech Support at Dell...

Several years ago, I worked on many Dell CPx 500 models in my work place. There was an issue that always involved a series of 4 or 5 keys (they were always the same keys) that would quit working and we had attempted to purchase new keyboards to fix the issue. It turned out, the real solution was to replace the 'motherboard' of the Latitude notebook!

Dell had knowledge about the keyboard/motherboard issue that we didn't know.
