Bluetooth mouse lag
Could someone else confirm if they are having this issue as I am beginning to wonder if this is a design issue.
I have had problems with my Latitude E6520 which is paired with a Dell Bluetooth Black Travel Mouse - the lag on it at times is absolutely criminal - it can be 1 whole second behind, by which time you end up clicking the wrong item/link, etc. It is driving me nuts!
Dell haven't been able to discover any issues, so sent an engineer to replace the Dell 375 Bluetooth Card. The replacement card did not work at all so another engineer was sent to replace both the motherboard and bluetooth car. This didn't work either, and it was left to me to work out that the bluetooth software needed to be completely uninstalled then reinstalled for the new bluetooth card to work. I am now experiencing the same issue with the new mobo and bluetooth card, so the issue persists.
Perhaps it is a software issue? This is why I would like to know if anyone else has experienced lag with their mouse on the E6520.
Thanks for any replies.

Which network card does your 6430 have? Mine is an Ultimate 6300 N. That card apparently has three internal antennas (other available cards have two or one) and I'm speculating that the card could be a source of the issue.
I found an interesting thing - when the unit is in my docking station, lid closed, and wireless off, the BT mouse works correctly.
I opened a ticket with Dell and will come back here and post if any resolution is found.

Ellswrth - any word back from Dell on this? I'm experiencing the same issue with a E6430 (had the issue on a E6420 as well) - pretty frustrating when you spend the $$ on the BT Module/mouse and it turns out to be completely unusable. Wired mouse and touchpad are OK, on the latest BIOS revision, etc. Just lags so far behind that it is impossible to use. I've got the Intel Centrino Advanced-N 6205 wireless card so I don't think it's card specific....I think the BT module, it's firmware or drivers just don't work right.
HEY DELL - Anyone out there listening?

UPDATE/RESOLUTION: So today, I decided to check and see if there might be an update to the Bluetooth driver. I didn't find any updates, but decided to re-download the Wireless Bluetooth 380 Module driver (Network_Application_X7R76_WN_6.5_A01.exe) and reinstall it.
When I reinstalled, bluetooth was DISABLED in the bios. So after the driver installed, I shutdown and enabled Bluetooth in the bios. Powered the laptop on. I then deleted any/all bluetooth mouse devices. Configured the bluetooth mouse to be discoverable and paired it with the laptop.
...and BOOM!! The mouse was working...but there was NO LAG!!!
That was about 4 hours ago and it is still working very nicely!!
Not sure what changed or what I did different since my previous post on 7/21, but it's all working now...

Wish I knew what magic trick you pulled to get it to work. I tried the exact same thing with 3 different drivers (one from Dell, 2 from Microsoft Update) and not a single one did anything to improve the responsiveness of the Dell Travel Mouse with my new E6430, and I've tried two Travel mice already.
Come to think of it, I saw a bit of responsiveness decrease when I got the E6420 too, but I didn't make much of it because the mouse was still perfectly usable. Am I the only one noticing that the Travel Mouse problem seems to be increasing with the Bluetooth version? On the E6410s, they worked great. On the E6420s, they worked good. On the E6430s, they are mediocre at best.
On the other hand, I do have a Microsoft 5000 BT mouse that is very responsive paired to the E6430. But I really like my Dell Travel mouse's functionality and comfort.

I've purchased a USB bluetooth adapter and all my devices work perfectly now.
I'd like Dell to acknowledge the issue, but I'm sure they will not. They'd rather have us pay to fix it.

Hi everyone,
I came across this posting while having issues with the 375 bluetooth card in my e6420. Mine weren't with a lagging mouse, but with my bluetooth keyboard--I thought it wouldn't hurt to post this here in case it helps you guys as well.
Long story short, after spending hours trying to figure out why there was lag going on after keyboard inactivity of only a few seconds (as opposed to 10 minutes when I use a dongle), purchasing a bluetooth dongle, and installing a bunch of different drivers, it all came down to a simple click of a button:
Under driver properties in device manager, click on the power management tab and de-select the option for the computer to turn the bluetooth card off to save power. This solved all of my issues with the lagging keyboard, and I'm hoping it might help you guys out as well.
Cheers!

Just found this thread, I have a 2012 Dell 6320 and a brand new Dell Black travel mouse. It works prett unreliably as others have described above. Some times I can remove it and reconnect to it and it works, now I can't reconnect it even after rebooting the 6320, putting new batteries into the mouse and trying again. Seems I will have to stop using the BT mouse and go with a USB port wireless mouse, USB cabled mouse works fine.

Yep, just did, it seemed to install ok, but then the BT mouse won't work and then it disappears from the divices list, while I typing this to you, it discovered it and is trying to reinstalli it, disappeared again....

OK, seemed to find a solution. On the Dell Touchpad page, Control Panel/Harware and Sound/Dell Touchpad, click on the Mouse, upper right, and in the bottom pane, there is an option to Disable Touchpad and Pointing stick when USB mouse is present, unclicking this option enabled the BT Travel Mouse to be installed and so far it seems to be operating just fine, the problem is, now the touch pad is live and you have to keep your fingers and thumbs away from it or it will move the cursor and change your location... so, not sure if there is another solution, but this one seems to works so far...

THANKS! This seems to have greatly improved the BT mouse performance with an E6430 notebook (Win 7 64bit Enterprise) I'm using. It's still a little laggy if I'm over a foot away from the notebook, but that's not my typical use so I'm good with it now. I also turned off the "power saving" feature on the BT card in Device Manager so that it doesn't have any lag time when it hasn't been used for a few minutes.
