No smoke. The machine remained in the docking station for two days straight without being moved; one day it worked well, the next it was crashing on bootup. Still works fine as long as I only have one stick of DRAM in it. Worked fine since about April of last year. I haven't had any issues with the power connector thusfar. Yeah, it's really weird. Several other people have had the problem, though, so it's not just me. But that said there's no guarantee that you'll run into it -- with any luck you never will, but I've reported what I found in case you do. One additional piece of info -- setting the BIOS startup to "diagnostic" in my case bombs when it gets to about 824M and generates a succession of short beeps in the pattern 3-3-1-2. I don't find that particular combination listed, but 3-3-1 is listed as either for an issue related to DRAM or the System Board. And where the same behavior results from swapping the DRAM sticks around, that leaves only one choice. Apparently there's also a site that explains how to find a single bad RAM chip on a stick of RAM to allow replacing the bad chip, however that doesn't seem to be the problem in this case, and even if it were the chips are a BGA package (Ball Grid Array) and thus there's no access to the solder leads because they're under the chip itself. -- Chris -- Chris Knadle [email protected] _______________________________________________ Mid-Hudson Valley Linux Users Group http://mhvlug.org http://mhvlug.org/cgi-bin/mailman/listinfo/mhvlug Upcoming Meetings (6pm - 8pm) MHVLS Auditorium Jan 7 - Ruby on Rails Feb 4 - TBD
