Hi,
Don't think it's a battery problem yet.

'Non System Disk' error says the floppy is not bootable.
Thos older Compaqs were 'very' proprietary!

Check your CMOS/BIOS to see if your hard drive is set up there.

Boot with a boot disk from any OS and from the A:\ type: dir/ and see what's on the hard drive.

Let us know, if we find out what OS is on there, we may get it booted for you.
