My new Lenovo M6811  has been encountering problems with my laptop. I hear a disconnecting noise while using the mouse and the cursor freezes but the LED remains on. After 10-15 seconds the connecting noise is heard and it starts working. This is happening too often and the same thing happens with the other USB 2.0 port as well as USB 3.0 port. Please help!
If it's new, better have it SOLVED under warranty.Hi

You need to check the power options version and update with the latest version from here.

There is instructions to check what version you have and how to install the latest drivers.

this should have been repaired using the THINK vantage update tool.  In most places electronic devices come with a warranty. The USER should not have to repair anything. Has the OP contacted the store?Geek

Lenovo's are supplied with Think vantage update software  for this situation . If a customer decides to take a unit back under  warranty when the fault could be fixed by running  the tools supplied the warranty agent WOULD  charge. This is because the agent is only paid for HARDWARE service not software problems .  Plus I would feel pretty stupid if it was me.
Software updates are for fixing rare or mild issues. The mouse behavior sounds more like a typical hardware issue. Either a bad bad mouse or a bad chips set or maybe a poor connection. Software updates do not repair really bad hardware.
Ask the vendor if this is a known issue that will be fixed with software. I  don't think so.


Hi

Does the same disconnect / reconnect happen with other USB devices like pen drives? If you do use a harddrive or pendrive to test make sure it doesn't have any important data on it.  Do you have another mouse to try ?
What model of mouse are you using ?.

Thankyou
