Take a small screwdriver and pry the chip out. It is a small chip about 1/4″ x 3/8″ with 24C16 embossed on it. On the top right-hand side, locate the programmable chip. Rotate the top using the location of the touchpad as the pivot point - that way you will disturb the touchpad cables at little as possible.

Lift the top half of the keyboard just enough to free it from the bottom half, then rotate the top clockwise about 4 or 5 inches, just enough to expose the programmable chip. Those are the cables that you don’t want to disturb. You can see the GlidePoint cables running from the touchpad in the top of the keyboard to the motherboard in the bottom of the keyboard. In the slideshow, you can see the top of the keyboard sitting on a little green box that lifts it about 2.75 inches (7 cm). Turn the keyboard over, so that it is face up and you are looking at the keys. Take the six screws (the ones holding the upper and lower parts of the keyboard together) out of the keyboard.

There are short cables that go from the GlidePoint touchpad in the upper part of the keyboard to the “motherboard” in the bottom part of the keyboard.īasically, the GlidePoint cables act as a sort of tether between the upper and lower halves of the keyboard. Working with Evolution keyboards is tricky because the Evolutions have the little GlidePoint touchpad in the middle of the top of the keyboard. (If it doesn’t, then the problem was something other than the programmable chip.) This should make the keyboard work normally.

You can just reboot the keyboard without removing the chip, of course, and that will fix the immediate problem. First you “reboot” the keyboard into non-progamming mode, then you remove the chip. (Bob noted that he removes the chip from any keyboards that he sells.)įixing the problem is a two-step process. If you are using a Northgate keyboard with any other system, the programmable chip is basically a bad chip and should be removed.

Unfortunately the programmable chip had software that worked only with Windows 98 and earlier. pressing the left shift key four times) puts the keyboard (that is, the programmable chip) into programming mode. They were designed so that certain key combinations (e.g. The Northgates are programmable keyboards - they contain a programmable chip. I talked with Bob Tibbetts of Northgate Keyboard repair ( ) and he explained the situation. The left shift key didn’t work and several pairs of keys seemed to have exchanged places. A number of the keys seemed to have gone haywire. Choose from a wide selection of HID® access control readers utilizing proximity reader technology.A while ago, one of my Northgate keyboards seemed spontaneously to sustain some kind of brain injury.
