Keyboard no longer responsive

Hi.

Try holding down the rightmost white key while powering up the keyboard. This is a minor system restoration, which may solve your problem.

Below is a way to run diagnostics as well >>>>

DIAGNOSTIC TEST:
if you think there might be something wrong with your board, you can have it perform several tests to see if all works well.
1. Power off
2. press C2# - F2 - G2# (all three together) and while keeping them depressed,
3. switch the power on.
You'll see the word "TEST" on the display
With Tempo - / + you can go to the test you want to perform. Start/Stop will start the test. Wait till a test is done!

Good luck and regards.

There are two samples for each note in the "Piano" sound samples. This allows you to play "soft = p" or "Loud = f" based on how hard you hit the keys.
The default setting of 2 suit most people. You can change the touch response to 3 (more hard) or 1 (less hard). With tough response set to 3 - you play mostly the soft samples until you bang the key much harder.
This is a keyboard that tries to give a bit of effect that an acoustic piano hammer mechanism would give.

Push the power button and wait for 10 seconds.

Computer specialists, learning over years have concluded there are thousands of different kinds of dirt, dust and grime (grease) that affect keyboards.

If you can clean the keyboard. I take no responsibility for how you might do it, but a vaccum can be of help if you ensure you do not suck up the key caps. If you place a coarse mesh atop the keys, you can keep the keys in place and then be safe.

Of course, if you are careful and handy you may be able to remove the top and clean most effectively.

IF my help works for you, you may indicate that.
G'luck.

Hi Marion

There is a limit to how many keystrokes a computer can retain ahead of what it is doing in real time. When the number of keystrokes entered reaches that limit, no further keystrokes can be entered and the warning tones indicate this fact to the user.

Try reestarting the computer to clear the error.

If the error persists after restarting, then probably the spring loaded mechanism under the key in question has become stuck in the depressed position. If so, try to gently lever the key up with the flat blade of a table knife, avoiding, if possible, unclipping the key itself.

If this is not possible, you might have to deliberately unclip the key to see if the mechanism under it is damaged. If it is not or it can be unstuck, then carefully re-clip the key.

If none of the above are possible, it may be necessary to replace the keyboard.

I hope this helps.

Hi gbadeboo,

To be frank with you , these are the signs that indicate that the keyboard is about to be damaged,

In the beginning you will have some keys that are malfunctioning then you will find some other keys with the same problem and this problem will affect the other keys as the circuit increases in damage.


I would recommend you to get a new keyboard as a backup and use the keyboard that you are using now , as much as you like.

Also if the keyboard is under warranty period , I would recommend to get a replacement before the warranty period expires.

Hope this helps. Thanks for asking the question on Fixya.

if it was just water ...shut it down and blow with cool air from a hair dryer until it will work ...not with hot air cause it has some plastic sheets inside..just let it dry ...and will work ,,if it was something else ..with sugar ..like beer..juice or so...it will need opening and clean well and dry and after that will work ..if it has permanent damages needs a keyboard replacing ...
meanwhile if it loosing its functions...just connect a usb based kayboard and use it instead..until replacement ..if the functions will not came after drying ..but if it was just water will get back after it will dry completeli and no longer make false contacts/..

Possibly a failed keyboard (was there a liquid spill?), loose keyboard cable or failed system board. Call Dell support, if your warranty is expired keyboard should be about $40-75, system board can be $200-600 depending on model and availiability of the part.

Replace the keyboard. Nobody fixes keyboard, because it is cheaper to replace it, and responsibly recycle the "dead" keyboard.

Try to plug it in different usb port, could be that port is bad. or it seems there is no good contacts between the keyboard and the port.
