Bluetooth problem win7 professional

Hello,

i'm using w7 professional on my 1555 dell studio laptop. even though i have the most update drivers for my bluetooth device, if i click turn off the bluetooth adapter when i turn on wireless to reduce power consumption, i can't see the bluetooth icon next to system clock for next system start!. there is not even a tray of bluetooth device on control pannel or on start menu?

do you have any idea about this problem?

i will be glad if you can help. because my solution is setting up the drivers of bluetooth again

check bios for "enable bluetooth on startup"
Then check Dell for the bluetooth software control package

hi,
thanks for the idea, bios setings were as enable on start up.
but i have realized that the bluetooth software somehow turned off from msconfig start-up settings. as i turned back on the problem disappered...

thanks for interest!
