Hi there,
My three year old PowerBook has just been returned to me from having a new CD-DVD drive and a new 1Ghz logic board fitted under warranty.
The new CD-DVD drive was fitted because the original had died 'of natural causes!' The new one works perfectly.
The new logic board was fitted because of a problem with the cooling fans being on all the time. In October I upgraded the HD from 60Gb to a Seagate 120Gb, but the fan problem was apparent whilst the original 60Gb HD was in place and continued after the 120 Gb HD was installed. The 60 gb was full and I chose the Seagate 120Gb because of it's 'silent running' properties.

Sadly the fan problem still persists - even after logic board replacement!
Both replacement parts I might add, came from Apple and are brand new. My questions are: Have I got another 'dud' logic board? Or is there something I can do myself to rid my PB of the excessive fan noise? Would resetting the PRAM help?
The machine works perfectly well, but I cannot listen to any music or spoken word recordings because of the noisy fans and working with the PB longer the 15 mins at a time becomes tiresome!
Also the techie in fixing my PB, created another account called 'Other' which shows up in the login window - I have tried deleating it but I cannot find any reference to this 'Other' account in 'Accounts' ...!
Any help or advice is, as usual, gratefully received!
