Hello Friends:
Just cleaning out storage and decided to sell my one-owner HP150B.
But first I need to make it work. It was working when I put it back in its boxes 20 +/-
years ago.
But, I can't get past the pre-boot error message, "Power-on test failed
0004" or sometimes "0000c".
Anybody know these error messages? Or better yet, where I can get a list of power-on error
messages?
