Hi,
I got a very pretty PB Duo 270c today.
Everything works fine and so I started to check and format its hard disk using a SCSI-connection with my PowerBook 540c.
Hard disk seemed ok and so I started copying install files and more from 540c to Duo 270c.
Suddly I noticed brown smoke from the Duo power supply and so I immediately plugged it out and the smoke stopped.
After that I used a known good universal power supply and I could continue to copy files.
Everything seemed ok again but now there is something wrong with the backlight of the PowerBook Duo:
When it starts I have to make it's display lighter each time, as I know this with passive matrix displays, when the PRAM battery is dead. Didn't know this with active matrix displays.
And then, when the PowerBook Duo is ready with booting, the backlight gets black in several steps (!) after a few seconds.
This is repeating after every booting up.
I can see the desktop with a pocket lamp.
So the backlight seems to be partly dead.
Could a (now) dead PRAM battery also be the reason of this?
Please tell me your thoughts about this.
Thanks.
