Problem with keyboard? - or something else?

**Misty** · 25-08-2020, 11:47 AM

I have a very fast Windows 10 desktop, gaming standard, because I have found I need it for photo-editing. A short while ago I bought a new wireless Logitech keyboard and mouse. Quite often when I start typing I find that the letters just do not appear. This happened when I first started typing this post, however, now that I am steadily typing all is well, which is standard. On occasion when this happens the letters I have typed start to appear quite a few seconds after, so there is some time-lag happening. However, sometimes the letters do not appear when I first start and I have to be very patient.

One thing I have tried is changing the batteries from the GP Alkaline that came with the keyboard. Now have Energizers, but the problem persists!

Have not yet tried a different keyboard, but will borrow one if you think it would be useful.

Something else which happens is that I highlight a piece of text, then copy, then click outside of the highlighted area to un-highlight. However, nothing happens, I click again and again and the text remains highlighted. So, my recent thinking is that the essential problem is connected with the wireless keyboard and mouse combination. Have just had a thought, that I should put the dongle (or whatever it is called) in a different USB connection - fingers crossed!

What thoughts please?

1) test with a wired USB kb & mouse , to confirm its a wireless kb issue

try moving the kb dongle to a front USB port ( or back USB port)
try the wireless KB on another PC/laptop

how old is that wireless kb ?
any lag with the wireless mouse ? (seems yes from what you've said)
is win10 trying to download updates in the background , or any AV doing scans ?

perhaps USB ports are going into sleep mode too quickly : disable USB power save in device manger , USB .

I'd bet its a wireless KB/mouse issue .
There may even be something interfering with its wireless connection to the dongle . Or its faulty/bad design .

Many thanks for the suggestions 1101. At the moment it is working fine, so seems to be intermittent, so will try moving the dongle to the front next time.

Re one of your suggestions re going into Device Manager, have done so, found this out re the keyboard -
1. Allow the device to turn off the computer to save power - unticked
2. Allow the device to awake the computer - ticked
So, we can cross that one off. The plus is that I have learned something new.

The USB controllers and devices in the Device Manager do not have the option of saving power, which is not surprising because it seems to be the devices that have this option only.

Ah, problem solved folks! Unfortunately putting the dongle in the front USB did not help. However, my marvelous IT guy said it can happen because of the distance between the tower and keyboard. He suggested that I put an extension lead on my dongle and keep the dongle near to my keyboard. Works fine!!

Must be a useless KB / mouse or Dongle if the range is to short on a std desktop. My media Center in the lounge has a 10 Mtr range.

Never tested it that far but its rock solid from 3Mtrs away.

Interesting. I had the same and thought it was caused by interference from the house wifi.
I've been using the mouse wireless and reverted to wired keyboard.

I had a very similar problem and it took me several days to trouble-shoot the cause; and it was interference from the wifi Router sitting about 2 meters away!
