Problems with Logitech keyboard/mouse wireless MK345 Model AND MK270. Both the keyboard and mouse are erratic. Batteries fine, plugged and unplugged toggle, then works for a short while. Any suggestions. Logitech help is pathetic.

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

There's got to be an alternative to this. If there is no other option, then why have a wireless keyboard in the first place? As I stated, this keyboard worked fine, no lag, prior to 2004. It started when I updated. Coincidence? I think not.

 

MK270 Logitech Keyboard giving wrong keys

I have recently installed windows 10 and had some issues with an old Logitech Keyboard so I upgraded that to a MK270 compatible with Windows 10 but still having the issue of cap2 = " instead of @ and cap3 = £ instead of 'hash', can't work out where this
has gone to. Have language set to English US International, have also tried uninstalling & reinstalling keyboard and various other languages.

Can anyone offer any other suggestions. Not all that computer literate so step by step please.

 

Logitech wireless keyboard / mouse hangs

Problems

• Intermittent nature
  
• The mouse will often hang (won't move)
  
• The keyboard will often not type
  
• Sometimes, the keys get saved up and come out later all at once, and sometimes they never come out
  
• The mouse seems to have difficulty traveling to the top left of the screen.
  

Equipment

• Dell Precision M3800 Laptop
  
• Windows 10 Professional operating system
  
• Logitech wireless keyboard (K270)
  
• Logitech wireless mouse (M185). They came in the same box / use the same dongle.
  
• "Plugable USB 3.0" docking station that runs the DisplayLink software. It has two monitors attached to it, one by DVI and the other by HDMI. It's plugged into the laptop by USB.
  

Troubleshooting Steps Taken

• Wired keyboard and wired mouse work great.
  
• When wireless was plugged in, it was in a USB port on the laptop itself, not the docking station
  
• I rerouted the monitors to plug directly into the laptop (take this docking station out of the equation). So far the wireless keyboard/mouse are not malfunctioning. This seems to indicate that the docking station is a necessary component to reproduce the problem). But I have to give it 1-2 days to make sure because the problem is intermittent.
  

Question

What would be a good first choice for a fix I can try that won't hurt anything (update a driver...where?)?
