Laptop Keyboard/Media Button Issue

January 2, 2012 at 13:06:57
Specs: Windows 7 Home, 8GB
I originally posted here my two issues over a few days in two separate posts. It was suggested that I try posting in the Dell forums. I combined my posts and posted there and as I expected not even one reply in over a months time. I am re-posting it here in its combined form to get one last chance on figuring this out before shelling out money on parts.

Dell Inspiron 1720
Upgraded to Windows 7 64 Bit (long time ago not recently)

4GB of RAM

All drivers/windows updates current

Issue #1

Out of no where last night my keyboard on my laptop went mad. When I push letters or numbers it will input the incorrect letter or number or even multiple letters/numbers. Not only that but other strange things. For instance, the backslash key single push types out the current date and time.

I ran Anti-virus and spyware/malware and nothing found. Using a USB keyboard works fine. Uninstalled and reinstalled keyboard drivers with no change. Same issue happens in safe mode and in all applications. Numlock is on. On or off the keyboard reacts the same. I ran Linux Live from a CD and in that text editor I had pretty much the same results with an addition issue. When I push one of the keys below the key would run on until another key or the same key was pushed, as if I held the key down. Other then the following keys, the rest of the keys work fine. Also, with numpad off the numpad keys work normaly.

1 (on the Num pad) = 17 (when initialy pressed after another key has been pressed and then works normaly)

7 (on the Num pad) = 17

9 (on the Num pad) = 0 sometimes 9

0 (on the Num pad) = 9 sometimes 0

a = inputs a single "a" and stops working until another key has been pressed.

s = \s

f = gf initialy and then just g

h = hj (when initialy pressed after another key has been pressed and then works normaly)

j = h

k = inputs a single "k" and stops working until another key has been pressed.

; = '

backslash key = 5:38 PM 9/21/2011\

Issue #2

The volume up button on the front of the laptop, the first time I push it the volume goes up slightly and then it mimicks the pause/play button until another button/key has been pressed. Then, it repeats the slight increase and goes back to mimicking the pause/play button.

Info/Questions

My Laptop has never seen moisture or liquid I can say without hesitation. I run up to date Anti-virus software and keep my PC clean constantly. I know a lot about PCs but not a lot about Laptop quirks. I havent done anything to it recently as far as new hardware/software. The laptop ran with no issues, this has happened out of no where. So my questions are; Is this a faulty keyboard? but what about the front media button would a faulty keyboard cause this also? Is this possibly a more serious issue or an additional issue?

If you tried a live version of Linux and you got the same results then you have a hardware issue.

Possible you just have a stuck key or two somewhere. If an external keyboard works OK then it is probably the integrated keyboard itself and not the keyboard controller. Solution appears to be to remove the integrated KB and see if you can clean it. If not, replace it.

What about the front media button would a faulty keyboard cause this also? This is where I get skeptical with ordering a new keyboard.

Just a heads up to help others with similar Issues, a new (used but not broken) keyboard fixed both issues. Hooray!!
