This is on one of our Dell Optiplex 780m mini tower machines.
We have several wireless Logitech MK270 keyboard/mouse combos.
For the last couple months, one of our keyboards has been giving problems; it started out with intermittent mild symptoms and has progressively gotten worse.
As best I can tell, the receiver is not a unifying receiver, although some of ours are.
It started out that, after a day or so of idleness, typing on the keyboard would not show up on the screen, or it would skip letters, or maybe it would ignore the first few letters before they would show up.
At first, the cure (at least for that session) was to unplug the little USB receiver and plug it back in, at which point everything would work good as new until after another period of idleness.
It has gotten progressively worse until now, after several various "repairs" and computer restarts, I can maybe name three folders and then it will maybe type the first few letters of the fourth one and then quit responding.
Sometimes, the letters are the only thing that will not respond, while other buttons will still work; sometimes, nothing whatsoever on the keyboard will work.
I downloaded a "re-connection" wizard from Logitech to no avail.
I have uninstalled the keyboard in device manager and restart, after which it may work for five minutes before quitting again.
The batteries test very good; not having any luck at anything else, I tried brand-new batteries anyway; new batteries did not help.
Throughout all this, the mouse has worked flawlessly.
I connected an old ancient ACER via USB cable; it was instantly recognized and hasn't missed a beat.
Of all of our wireless keyboards, this one that is giving problems is the most recently purchased and is less than a year old.
I can "uninstall" in device manager, but I cannot see any driver for the keyboard in programs, nor did my visit to the Logitech site turn up a downloadable driver.
Has this keyboard just malfunctioned and needs throwing away; or, is it a driver problem; or, is it a Windows 7 problem ?
Do I fix; or, do I just toss it and try another one ?
Thanks for reading.
