Just got this baby this morning 
Very cute and in good shape. German Keyboard.
It started on the first try, VERY noisy Hd, and a rectangle of dead pixels on the bottom left of the screen ( which is more convenient than the usual PB150 screens upper right dead pixels rectangle
… Otherwise Ok.
Then after two boots , stopped booting again and after the chime i get a 4 tones "Dah dee Da da" …?!
Looked around a bit and it seems it's = " 4 beeps = Bad checksum for the remainder of the boot ROM" .
is it fixable ?
Happy anyway, first time i see a Duo, pretty machine
