Hi Futoji,
I got some time to check this again.
Bluetooth and Wi-Fi are disabled in Device manager.
When I reboot and enable "Virtualization" in BIOS, the hangup is still seen.
I tried to to a hard reset by removing the battery and then rebooting. it did not help
Is there a way to disable BT completely? I dont need it.
I am disappointed with the pain that HP is causing due to usage of unstable H/W (Ralink) and buggy device drivers
Thanks
Dixit
