Lenovo E540 usb mouse randomly disconnects reconnects

2015-04-18, 17:34 PM

Hello , 


I bought Lenovo e540 1 month ago now i installed windows 7 os which i was using on my previous laptop , 


problem is i have usb mouse that i am using for almost year and half . i plug my mouse in and after some time it disconnects and reconnects randomly . i did the following : 

  • Reinstalled all drivers 
  • all drivers are up to date (lenovo and mouse (HID) driver) 
  • I changed power settings on laptop not to shutdown usb ports for power save
  • I changed power managment option on Device  Mangaer
  • I even changed settings in bios so my usbs can act like 2.0 

But nothing helped , so far nothing helped what seems to be problem ? this didnt happen on my old laptop so its not mouse problem

Hi Dali360,


Welcome to the Forums   


As per the query we understood that you are facing issue with mouse randomly disconnects in your Lenovo E540 laptop.


Check the mouse by connecting to different USB ports and also boot the system into safe mode and check if the mouse disconnects in safe mode as well.


Hope this helps. Do post back if the issue persists!                                                   


Best regards,
