T500 Keyboard types garbage characters

2010-03-11, 21:54 PM

I've seen this problem occasionally both on Vista and now on Windows 7 (64-bit) - now and then when I type on the keyboard I get garbage characters on the screen.  The characters seem to appear in ASCII-code order, for example if I type 'http' I might see '1234'  or some other 4-character sequence, in order.  This has happened in Thunderbird, and goes away after a while.  It isn't specific to Thunderbird, if I'm in the 'garbage character' mode and open a Notepad window, for example, it will also display incorrect characters.  After closing a few things and re-opening, it eventually clears up (I'm not sure about the exact sequence that corrects it).

 

I've searched this forum and other places but not seen any references to a similar problem.   Any ideas would be welcome!

Do you have other language installed on your OS?

 

Control panel -> region and language -> keyboards and languages -> General.

Yes - I have the Spanish keyboard installed, but I saw this on W7 before I installed it.   After I re-installed the spanish keyboard I thought that swiching between them would solve this issue, but it didn't - it remained in this state after toggling to spanish and back to english....

Check that NumLock isn't on (If it is, turn it off with Fn+ScrLk).

Nope, not that - the garbage characters can be anything, the '1234' was just an example.  It might be ()_+ or kl;' or .... well, any ASCII characters.

This problem is still happening, occasionally and randomly.  For example, just before typing this post (which is working normally, it seems), I was using another app and had the problem.  I opened Notepad, and typed "jjjjjjjjj", repeatedly, and this is what appeared on the screen:

 


qwertyuiop[]asdfghjkl;'`\zxcvbnm,./-+\1234567890-=

 

and would repeat if I continued to type any letters at all (didn't matter if it was "j" or any other letter, the same sequence appeared).  Then, I switched to the Spanish keyboard, and tried the same thing and saw:

 

qwertyuiop´+asdfghjklñ{|}zxcvbnm,.--+<1234567890'¿

 

Again, it would repeat endlessly as long as I kept typing something.

 

The shift key would produce the corresponding capital or shifted characters (i.e. "%" instead of "5").

 

It clears up spontaneously, but is rather annoying when it happens.

 

It is not caps-lock or num-lock related, nor apparently multiple-language-keyboard related.

 

Any clues???

 

Thanks!

do you have an external usb keyboard? try to use an external keyboard and test this problem.

 

Also, go into your rescue and recovery console by pressing the blue thinkvantage button during the startup, now select hardware diagnose, in that do the keyboard test.
