I have a new A700 and unfortunately didn't pay attention to some of the reviews I read about problems with Bluetooth mouse lag and keyboard responsiveness. The mouse lag is severe and seems to be tied to some kind of workload on the system, perhaps network. I had to connect a USB wireless mouse to use the system. The keyboard goes to sleep and you end up typing 3 or 4 characters before it wakes up. This is annoying, but I am working with it. The wireless Bluetooth keyboard and mouse were a major differentiating factor when I bought the system. Is anyone else experiencing these issues, and if so have you found a fix?
Solved! Go to Solution.

I have a friend who is currently experiencing the same issue. Check the keyboard and power options setting for bluetooth. You should be able to turn off the sleep mode if it is indeed related to that.

Just got an A700 and have this problem as well with BT mouse. The keyboard works ok but I need to have the mouse next to the screen (left side idealy) to have it work. Still looking for a workaround or will be calling support.

I have noticed the same thing wiht mouse lag, and I am using Linux on my A700, sounds like Lenovo needs to release a new Bios for this system.

Update: I ended up calling support. They mentioned some issues with driver on windows 7 64bit and updated the BT driver. This did not resolve the problem and decided to send a new BT card + KB/Mouse. A service guy came today and replaced the BT card which seem to solve my issue. They also replace KB/Mouse (but don't think it was necessary). I don't have to be close to the screen for the mouse to work now.

Everyone with bluetooth issue, download the driver for Lenovo A320

Few days ago, I've just bought my first-ever Non-DELL, the A700 having compared with so many DELLS and thought it's a good machine.
But this BT lag has really put me down. I use my PC for almost everything from browsing to hosting DBs, so precision is a paramount for me. Very disappointed with this BT issue both on the Mouse and Keyboard.
Has anyone downloaded the latest broadcom BT drivers and solved the issue? I will try tonight and let you all know if that works.
Also has anyone from the UK had their BT card replaced and got the Mouse/KB working fine?
Failing with driver update, shall contact Support.
Any advise welcome.
