Windows 10: Keyboard input lag (Logitech K270 wireless keyboard, Windows 10 20H2)

Hi there. I've got yet another Windows 10 problem. lol

This time it's my keyboard. I'm using a Logitech K270 wireless keyboard, on Windows 10 Pro 20H2. I have been experiencing keyboard input lag off and on for a couple months now, and I've searched for possible solutions, but none so far have worked. I was hoping you guys could suggest some fixes.

Here's what I've tried, based on the suggestions I've found on the web:

• Updating the keyboard/dongle's drivers (there are no drivers on Logitechs's site, oddly) and firmware. Nope.
• Swapping USB ports. Nada.
• Unplugging any extraneous USB devices. Zilch.
• Checking the batteries. No joy.

As I was typing this it was lagging here and there. It's a bit disconcerting. Anyway... I don't think I missed anything, but if you need more information or diagnostics, lemme know and I'll upload 'em.

:)

Can't get Logitech K270 keyboard to work

Did the mouse and keyboard come as a set? If not the unifying dongle may be wrong for the keyboard which would explain why only the mouse works. The mention of "found" suggests the set may have gotten separated from each other as some point.

Can't get Logitech K270 keyboard to work

I have a Logitech K270 wireless keyboard that I found along with a Logitech wireless mouse. The mouse has a unifying receiver. I plugged the receiver into a desktop computer and ran the Logitech firmware update, but only the mouse works. I made sure I had both devices turned on when doing the update, but to no avail.

I also tried this using my laptop. Still no luck.

Should I just throw away the keyboard?
