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!
