MW-520 Random Shutdowns

After about 5 months of not using my MW-520, I had to fire it up again to reprogram a radio. I get about 5 minutes into work and the MW-520 randomly shuts down. Any ideas as to what's up? It's a Win98/DOS dual boot machine and I'm going only into DOS, I haven't tried going into Win98 yet in about 5 months now either.

EDIT: Same thing happens in Win98 as well...

My bet is your loosing power to the processor.

Have you checked the power feed for the correct voltage?

Have seen some computers where the internal backup power battery was about stone dead. When you power up the box, it lasts for a short while and the power supply system crashes and can't sustain the operation. The hard drive pulls too much power trying to do it's thing and the whole computer just shuts off.

I would start with the battery and see what condition it's it.

Is it heating up? Possibly not after 5 minutes, but you never know. If the machine is full of dust or anything else that makes for a nice cozy blanket for the proc and other components to get nice and hot and shut down from the thermal overload.

Jim,

Power is correct at/around 14 volts, it's only drawing about 2A when powering on though. The dust isn't an issue either. I'll have to order new backup batteries as they aren't readily available at the local "shack".
