Well, with all the problems I had, and being a bit tired at the end of a day like today, this had to happen. While trying to setup an internal CD-ROM drive in a hard disk enclosure, I did accidentally create a shock. My Duo 280c wasn't turned on, and the CD-ROM wasn't connected to the SCSI chain. However, the shock was bad enough that everything on the same powerbar seem to have badly suffer from it. First, the CD-ROM drive itself wouldn't power up, even if there was still power from the enclosure (measured with multimeter). Upon opening the drive, I immediately noticed an IC that was half melted. That was starting to look bad. Then, continuing my inspection of the damages, I noticed that there were no power light on the EN/SC, even if the adapter was delivering its 12V. Cranked open the case, and there, also, was a melted IC, with some tiny parts falling from it. I immediately went to the Duo, but all my attempts to start it failed. I've then inspected the power adapter. No power was coming from the plug that goes in the Duo. I also opened the case, but a visual inspection didn't reveal anything wrong, but there might be damages that are not visible. The fuse was still intact, but no power. I then tried to startup the Duo from my 2 batteries, but it wouldn't. With the battery that was charging at the time of the accident, I think I could hear the hard disk spinning, but no chime upon power on, nothing on the screen. After reading a message from another poster to this list suggesting that the power manager has killed himself, so I went open the Duo, disconnected the battery and the backup battery and I let the unit completely powerless for 10 minutes, as suggested in the Service Manual. I put back everything together. But I still can't start it from any battery. The sleep light does lit when I press the power switch on the back, but that's all it does. I did carefully inspect the ICs on the motherboard (at least those visible when the keyboard is removed, and didn't find anything suspicious. I took the reading of the battery power. The one that was recharging was reading 13V, the other one 12.20V. My question is, is my Duo dead? Can you start it from a battery after a power manager reset? Any suggestion? If something is fried, what could it be? Is there a power supply on a Duo? Should I try to replace this? Or get a new power adapter to see if it helps? Folks, I need some positive thoughts, or it's going to be the worst day I had in a very long time... Sniff Sniff... Thanks. -Laurent. P.S.: Mark, I think you got a bunch of Duo the other day. Anything useful to me that you would be willing to part with? ============================================================ Laurent Daudelin <http://home.cox.rr.com/nemesys> Logiciels Nemesys Software mailto:[EMAIL PROTECTED] ---------- Duo/2400 List, The friendliest place on the Net!
