Logitech MX 5500 Revolution keyboard has no numlock

Considering how many times/posts I mentioned that keyboard
combination without knowing the keyboard limitation, I should
be clear about this.
There is no numlock Key on the Logitech MX 5500 Revolution
keyboard and mouse combo. At $80 total, I do not feel cheated, but
it's weird. The keyboard has some other innovations. The Insert
key is removed to a different location, a positive development IMO
since I never use it and since I rarely (but sometimes) hit it by
accident. Also, the LCD display is dim, with no backlighting. Plus
the unmovable palm rest, the keyboard is very deep.
Apparently the numeric keypad keys send a prefix numlock off code
with each sent key code, so the missing numlock problem cannot be
solved by assigning another key as that function.

keypad number key, a prefix (numlock-off code) is sent with the
key code.
You might be able to work around it with a key hook macro that
checks numlock status and replaces keypad number keys with the
proper key code (with no prefix, of course). Logitech could do
that in their Setpoint software, if they were interested.
Another problem is that the "ClearCalc" key appears to send the
exact same key code (with no extended key flag) that the backspace
key sends. Yes, it appears to be simply a duplicate of the
backspace key.

There is no such key on the real thing.

In the quick start manual, it shows the shift lock indicator on
the left of the LCD screen, in fact it's on the right.
Logitech is screwing up royally. Getting rid of the MicroGear
SmartShift when they trashed the other MX Revolution stuff was
like throwing the baby out with the bathwater.

The mouse looks better made than my original. The keyboard looks
immaculate. Every modern picture of the MX5500 Revolution keyboard
shows an LCD display, unlike the link provided by the prior
poster. Also, if it were a counterfeit item, they wouldn't have
blacked out the PID numbers.
Now my prior assessment has some evidence (the numlock fiasco) to
go with it. These kits are probably straight from Logitech, not
"manufacturer refurbished" because Logitech didn't want to support
them anymore. The whole MX 5500 Revolution keyboard and mouse
combo thing looks like innovation gone wild. The secondary
pseudo-mouse wheel was another silly idea, especially given its
stiffness. Too bad they threw out the brilliant SmartShift with
the rest of it, though.

The black box that contains the inner plastic tray with the
magnetic anti-theft strip stuck to it is shown there inside the
retail outer covering. The only difference (besides the missing
batteries) is that the FleaBay version comes in a clean looking
perfectly sized cardboard box.
If they were counterfeit, they wouldn't be "seller refurbished".
It's very neat stuff (except for Logitech's design flaws), the
alleged counterfeiter could've easily made and outer cover for
it.

Just a WAG, but might there be a function key combo that would change
the prefix to "numlock on"?

// The MX5500 does not need a switchable NUMLOCK key because it does not
have other options on the number buttons.//
There are actually a number of topics on the issue in the forum.
Another one sez:
// So far as having it function as if it understood numlock was off,
hold the shift key then press tha appropriate key. I discovered this
quite by accident but it works well in the games I've tried it in. //
There's another topic in which a guy made a registry change so that the
condition of the numlock on keys was instead as if numlock were off; but
then there was a version change of logitch software and his workaround
didn't work anymore
http://forums.logitech.com/t5/Keyboards-and-Keyboard-Mice/MX5500-NumLock-Insert-keys/m-p/647078
This is a tiny excerpt from one of the posts which is typical of many
// I just want to add my disappointment and anger to the throng of
customers who find it outrageous that their new, very expensive,
keyboard doesn't have a switchable NumLock key. This was never revealed
in any advertising for it that I read. It is as if I bought a keyboard
and only discovered after the fact that it isn't qwerty! I've been
using the combo number/navigation keys for the latter purpose 98% of the
time since I bought my PC-XT 26 years ago. That's a very deep set of
habits to have to overcome that I would choose not to change in the
first place. I would not have purchased it if I knew ahead of time that
it had this deliberate flaw. //

statement is outrageous. Because your keypad keys have numbers
(without arrows) printed on them, they cannot be used for arrow
keys?! THAT IS A VERY SILLY IDEA.

Now we have:

it in the body as proper netiquette
- even worse, top posting untrimmed no-context conversational disorder
- more/persistent foolish header pasting
I can make your bad mannered posts disappear from my view permanently or

I don't feel threatened, just expressing my opinion that kill

My hook shows that the 5500 numlocked keypad input is precisely
the same as a normal keyboard's. With two keyboards connected, one
works with numlock enabled while the other works with numlock
disabled. That is, unless the normal keyboard is used immediately
after the 5500. As a user mentioned on the Logitech forum, the
5500 keeps numlock enabled for a few seconds after each numeric
keypad input, after it initially ignores the numlock-off setting.

So far, the MX5500 Revolution combo works great. If the mouse is
mechanically new as it looks, this is a steal for $80. The
keyboard is heavy and large/deep, but it's sturdy and the
keystroke action feels very smooth and solid. The missing numlock
is no big deal if my new flight simulator (X-Plane 10) allows
using the keypad for functions. Apparently the keyboard detects
whether numlock is disabled and only then sends the additional
numlock-off code. (In other words, the numeric keypad key codes
are the same as long as numlock is enabled. Otherwise, that might
have been a concern when using keypad keys for steering, since the
target program probably needs to know whether a key is being held
down. A professional programmer might be able to do that, but not
I.) The LCD display can be electronically switched so that the
background is white and the foreground is black, so it shows up a
little bit better with some lighting (not at all when dark, there
is no backlight). In office lighting, you might even be able to
see the small print. Haven't used the mouse yet, I'm confident
that works perfectly. It did charge properly.
And that will be it if no further questions or comments, and
unless anything is not exactly right (X-Plane should allow using
the keypad for steering, until I get a yoke).

That's not how PC keyboards work, at least not according to the
original IBM standard.
The keyboard sends a "scan code" that identifies the keypress.
See http://www.users.on.net/~fzabkar/MSKeyLog.TXT
When the NumLock key is pressed (make), the keyboard sends a "0x45"
code to the keyboard controller on the motherboard. When the NumLock
key is released (break), the keyboard sends "0xC5" (= 0x45 + 0x80).
The keyboard does not maintain a record of the numlock state. That is
the job of the OS. The OS responds to the NumLock keypress by toggling
its own NumLock status, and then sends a command to the keyboard to
either turn on or off the NumLock LED.
When you press a key, the keyboard sends the scan code for that key,
not its ASCII code. For example, let's say you have a keyboard with
100 keys. The "A" key on a US keyboard might be key #52, whereas the
same physical key position on a Japanese keyboard will be something
else entirely. However, if the keyboards are electronically identical,
then key #52 will have the same scan code for both keyboards. The OS
determines the ASCII code by looking up the scan code in the US or
Japanese key maps.
Similarly, let's say you have pressed the Home/7 key on the numeric
keypad. The keyboard transmits the same scan code for either Home or
Num 7, but the OS determines how to interpret the key by referring to
the OS NumLock flag.
To illustrate this behaviour, I have an AT style keyboard connected to
two PCs via a passive KVM box. If the second PC is powered off, then
switching the keyboard to PC #2 and back to PC #1 effectively power
cycles it. If the CapsLock and NumLock LEDs are both on at the start,
then they will be turned off after a power cycle. However, pressing
any alphabet key or numeric keypad key still produces uppercase and
numeric characters, so it is clear that the OS is remembering the
NumLock and CapsLock status, not the keyboard.
Having said the above, I have no idea whether the PC/AT specification
is valid for your keyboard.

With or without numlock... The numeric keypad is dysfunctional
without Logitech's Setpoint software. Keyboard hooks (KeyInfo,
CharProbe, and mine) see no key code, no scan code, nothing at
all. So, apparently the MX5500 Revolution keypad input is enabled
by Logitech's software.
Microsoft's low-level hook SetWindowsHookEx might see something,
but it's not worth the effort.

Note: to invert the keyboard backlight, press FN + Insert
FWIW. Apparently the left mouse button is malfunctioning. Maybe I will
take apart, someday "somewhere over the rainbow..." In the meantime...
I can work around it by voice commands, though.

Don't know if this helps, but I just pulled the batteries out and put them back in and let the keyboard go through it's initialisation. All numpad keys worked again. It's happened twice in 4 years so I can't complain :)
