Awake from sleep, bluetooth disappear, cd not reading, any link?

Hi there,

I have a MacBook CD 1,83 with some strange symptoms.

1/Bluetooth is, most of the time, not showing in the pref pan. It appears "when it wants" and disappears.

2/When bluetooth does not show, the MacBook do not want to go sleeping (when closing the Screen). Well it goes but awake after few minutes (the optical drive is working like when starting). And same if I leave it and wait it goes sleeping. If bluetooth appear, no problem.

3/ optical drive is not reading anymore. I can insert cd, take it out, no problem. It "tries" to work but nothing comes on the screen and the MacBook eject the cd. When I check on pref pan, it appears an it makes noise when I click on its icone. Model is MATSHITA CD-RW CW-8221. Also appears in disk utility.

I have asked for repair (an apple retailer) and they said the problem was the logic board and the bluetooth. They both need to be replaced. But it's strange I do not have any other problem if this a logic board failure and what is the link with bluetooth???

So could it be the bluetooth that causes all this mess??? Is there any problem if I take it out?? (I do not need it). It worth a try, I guess.

Has someone any clue? If there is no more bluetooth board is there any problem??

Thank you
