I have seen this same problem with an HP 6200 Pro SFF PC running Win7 SP1 64 bit.

After researching the problem I came across this keyscan testing software.


We have not resolved the issue but we believe it to be an HP issue or a toggle in the BIOS for the keyboard.



Here's the email thread on this issue.

We are having an issue with our software working with an HP 6200 Pro SFF PC under Win7 SP1 64bit.

The Shift-Esc sequence doesn't work. We believe it to be a scan code issue.

We found your software to test scan codes.

Running a test on a working machine we get:

OnKeyPress <-

OnKeyup, Key code=27, Control Keys=Shift, Key name ESC OnKeyup, Key code=16, Control Keys=, Key name SHIFT

Running a test on a NON-working machine we get:

OnKeyup, Key code=27, Control Keys=Shift, Key name ESC OnKeyup, Key code=16, Control Keys=, Key name SHIFT

The difference is that on NON-working machine the first line does not display.

Any idea what that first line is doing?


PS: Note my substitution of <- for a character that I would call a small left arrow but which I can't find in an ASCII chart.

We upgraded several developers today to new HP PCs, going from XP to Win
7. Now the System Request key (Shift+Esc) does not work on Client
Access. I went to Win 7 a couple of months ago and I do not have the
problem. We tried my keyboard map on a new machine and it also failed.
We can map System Request to another key and it works as expected.

We’re at version 7 of client access with service pack SI44594, which is
recent. Personal Communications is version 6.0 and the build (?) is
20111019 S.

This IBM page indicates it might be a hardware issue:

Personal Communication 6.0.4 is a fix:

But I’ve just found another page that says it was fixed in 5.9.8:

Anyone else run into this problem and found a fix?
Thanks, Sam,
