pcoghlan+cctech at vms.eurokom.ie (ORCPT pcoghlan+2Bcctech at vms.eurokom.ie); Thu, Reply-to: "General Discussion: On-Topic Posts Only" <cctech at classiccmp.org> My AlphaServer 1000A 5/333 and 5/400 both beep during or after the POST. I also have a number of DEC machines that failed after sitting for a few months. I posted about them around the time of the "Leaving computers on..." thread about a month ago but I never saw my mail make it to the list for some reason. The CPU module is removable and I have had trouble with one of my machines fixed by reseating it. However, the symptoms were different - there was activity on the display and there were beeps giving error codes. I have also had a problem with a failed Bcache on the CPU module (it seems this can be a weak point on the AS1000A) and I had memory failures. However, neither stopped the POST displaying on the LCD nor the graphics console from working. I would suggest reseating the CPU module and removing any PCI cards present. (I have an Alphaserver 800 which became a complete brick while a combination of PCI cards were present that it didn't like.) If there are any EISA cards present, I would leave them in place because there may be issues with the config utility that has to be run when the EISA bus configuration is modified. Other than that, I suggest trying the system with just the bare essentials present and seeing what happens. It would be useful to know if the fans start. Fan problems on some alphas cause the whole thing to shut down. Also, there is an interlock microswitch to prevent power up when the cover is open. This is probably not the problem here though as the symptoms are as if the front panel power switch is off. Regards, Peter Coghlan.
