I was searching a solution for this with Google, but either I didn't find anything, or I've found what I already knew, tried or was looking for, but either didn't worked, or didn't found any. Or it was a complete failure. Either way I suspect, that it has not yet been asked, so I'll ask it.
I've recently bought a HP ProBook 470 notebook, with FreeDOS preinstalled on it (or with no OS as it was advertised on the site), and installed Windows 7 and Ubuntu, dualboot. My issue is with Windows.
Off-topic: I also disregarded the accompanied notice, that I should not remove the pre-installed system, as it comes with an optimised video driver; as there is no ATI driver for FreeDOS (if I'm not mistaken) but I couldn't have use any advantage of it anyways. I just thought I'll mention it. :P
One of the thing I wanted to test with this laptop, is to use it as a headset for my phone (that I did before on my previous laptop with success, but it wasn't HP's) but it didn't worked on my new laptop, there is simply no option for it.
Removing the connection then reconnecting it I checked what drivers are installed, and it seems that the following drivers are installed (removed 'Bluetooth' prefix):
A2DP Source
AV Remote Control Target
OPP
Phone Book Access
Handsfree Audio Gateway
NAP service
I now know, that what should interest me are the "Hands-free Audio Gateway" and the "A2DP Source" drivers. Checking the phone action/control panel/window thingy more thoroughly (that is different from what I had on my previous laptop, so I guess it is a Bluetooth driver software, and not a Windows utility), I see that I can start a phone call from it, but that is not what I'm looking for; to the phone, it is paired, but not connected to the laptop, and that is inconvenient for me.
When I've installed Windows 7, I've used the HP SoftPaq Download Manager to download drivers on my laptop (after I started to download few of them by hand). I just run it again today, before reconnecting my phone, nothing changed.
I don't know what now. I know that my phone is capable to use this functionality, and also this laptop is capable to recognize it, and I suspect that it would be capapble to use it, but there is no interface on the system. Any suggestion?
