First thing I would normally recommend is to download the latest System 
Setup/BIOS, but if this is a power system issue, it may not be doable. 
Check to see if you can boot to the BIOS/Setup with the AC adapter and 
a charged battery installed. If this works, I would try to set the  
BIOS to the DEFAULTS and then update with the latest version.

My suspicion is this is the DC Converter, the actual power supply and 
power converter for the laptop, that has failed or is failing. It could 
even be a simple "bum" connector. But I suspect this is the problem and 
that should have been replaced.

Are these still under warranty?

If you have another working battery and AC adapter, test the faulty 
setup with these. If you are using anything other than the IBM supplied 
adapter for that unit, please cease and desist! No kidding here. Even 
mixing IBM AC adapters will lead to problems if they are not the 
correct model for the system in question. Throw them away if you have 
any laying about.

If the above works, great! But I have my doubts, this is just 
troubleshooting.

OK, very much doubt this is a HDD issue, all symptoms point to a power 
system problem.
