It's a relief to know that I'm not the only one having this problem. I
am using Vista Ultimate 32bit version. Prior to purchasing my new DELL
XPS m1210 notebook I had been using the MS Desktop Elite for Bluetooth
with my Dimension Desktop with no problems. I then let my wife use the
set with her Inspiron 600m (using the built-in Bluetooth receiver) and
it works like a charm. These scenarios of course are all involving
computers running Windows XP Pro sp2 and not Vista. With Vista, I am
experiencing the same problems with the disconnecting as you guys seem
to be.
The annoying thing is that both the mouse and keyboard work most of the
time. They also work when I first boot the system and login without a
proble. In fact, if I use the mouse for an extended period of time and
don't use the keyboard, the mouse never seems to lose connectivity. It
is only AFTER I have used the mouse for a long period of time WITHOUT
using the keyboard that the keyboard seems to disconnect. The
super-annoying thing is that as soon as I hit a key on the keyboard and
realize that the keyboard is not responding, it causes the mouse to stop
responding too. Now I don't mean "Not Responding" in the sense of a
system or application hand, rather it's like the keyboard just realized
that nap time was over and wanted to tell it's buddy the mouse to wake
up too! Only the mouse never went to sleep to begin with. So what seems
to happen at that point is that the mouse just seems to assume that the
keyboard must know what it's talking about and it too decides to
disconnect. It is at that point where neither of the peripherals work
but then about 10-15 seconds later they come to life. This happens like
all the time.
I am pretty positive that this is like a bluetooth stack issue that
Microsoft needs to fix. It isn't a power saving issue b/c I have taken
every precaution to ensure that I have everything running at full power
and that none of my hardware should go into any sort of
"sleep/hibernation/suspend" mode. There is even an option in the device
manager where the bluetooth adapter is listed where if you right-click
on the DELL Truemobile 355 Bluetooth + EDR device and select
properties->power management that you can tell Windows NOT to allow the
OS to turn off the device to save power.
Anyhow, I await a patch from Microsoft. Here's hoping.
