I acquired a Packard Bell Legend 103 Elite system a few months ago. Since obtaining it it has been consistently throwing an invalid CMOS error each time the system starts. First thing to check was the barrel battery and replace it. There was some minor leakage but nothing that appeared to cause any operational damage. Upon replacing the CMOS now retains the system configuration however the error remains. I've restored the default settings and then reconfigured the system for the components installed. While I haven't done any in depth troubleshooting I have done the basics and I am now looking for ideas of how to track down the source of this error.
The configuration is: 80384SX-25MHz, 12MB of RAM, 131MB HD, 1.2MB (drive A) and 1.44MB (drive B) floppy drives. I have removed the HD and replaced it with an XT-IDE CF adapter which is working fine (the error message appeared before I did this). I have since installed a different 131MB HD (I wanted to preserve the contents of the original and I need a real HD for the things I need to do). No matter the configuration this error persists.
All the jumpers are set as they originally were (I temporarily installed an 80486DX-33MHz processor as that's where I ultimately want to go). I noted the jumper settings before doing this and have restored them to those settings after returning the 80486SX part. I suppose maybe one of the jumper settings was incorrectly set before I obtained the system but I have reviewed the settings and don't see anything that would look like the source of this error. Thankfully Packard Bell was wise enough to put the jumper settings on the top case where it is easily accessible and readable.
Aside from this error the system appears to be fully functioning. The only issue I've observed is I cannot have the date set beyond 1999 (I currently have it set to the current date for 1995) but that is likely because the BIOS is not Y2K compliant. Does anyone have any ideas why this error will not go away?
