Windows 10: Keyboard lag

Whenever i press certain keys my keyboard starts to lag, as if i'm constantly pressing tab. In command prompt the lag is different, it spams "^z" constantly. Any idea on how to solve the issue?Lag does not happen in games.

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.

 

keyboard lag

I have four Packard Bell laptops that I keep running for members of the family. They are old models, but adequate for everyday browsing and emails. The models are all GN45 easynote skype. One by one all exhibited irritating keyboard lag using the onboard keyboard. They didn't do it in safe mode, nor with an external usb keyboard. I tried all the usual things, updating drivers, checking the ram sticks, running sfc and DISM, restoring from an acronis image etc. By chance I read one answer on this forum from someone in Poland who suggested checking the CMOS battery. So obvious when you think about it, but surprising that only a few people out of many thousands ever suggest this as an answer to keyboard lag. I checked the batteries, which on the GN45, unlike more modern laptops, are easily accessible under the wifi card, under a panel that exposes the wifi card and ram sticks. The batteries were dated July 2006 and were down to negligible voltage. Replacing them restored keyboard function and also noticeably speeded up usb file transfer etc. What was weird was that there was just enough voltage to keep the date and time, which is the usual way you know to change the CMOS battery.
