Hi to all,
First to introduce you my problem, I've bought two month ago HP ProBook 4540s and I had several BSOD, then I returned it to service and they changed motherboard. After that I've installed Windows 7 and I've noticed that now it is HP 4440s but I don't care. After that I've noticed BSOD while surfing and using wireless HP x4000b mouse by bluetooth so I've figured out that problem is with using parallel WiFi and bluetooth cause probably they are on the same card. So the point is are there any drivers that can support using it the same time or they aren't.
P.S. Service in Republic of Croatia is shameful as it is the HP support, lame, slow and no real help, but that's life.
