hello friends,
a fews back I bought a brand new dell inspiron 1545, with core2duo t6500,3 gig ram, windows vista home basic. The built in bluetooth device was working perfectly utill now.. but today i noticed that the bluetooth icon is missing from the task bar system tray.so, i am unable to turn on the bluetooth adapter..! i checked the startup programs from windows defender and broadcom bluetooth is permitted. Infact when i checked with taskmanager bttray.exe is running..! its just that i cant find it..! moreover i searched for bluetooth in the search box, found the icon, suprisingly it is not opening..! the cursor comes live for a fews secs yet it doesnt open..! nothing is happening..! barring this problem my laptop is working perfectly.! i dont want to reinstall the bluetooth drives or other softwares.. what might be wrong? mark my words, i didnt play around with any bluetooth settings! what might have caused this bizzare problem? how can i turn on the adapter and connect my mobile phone to it? help me.. help me..!
