After a start-up failure ON MY CQ41-207TX, I ran diagnostics and it said START-UP TEST FAILED. failure id: M4M423-00071D-WD7U21-C0DG03 PRIMARY BATTERY. I ran start up diagnostics without the battery and it passed. With the battery still out and I tried to start on power cord, but no success. I put in my spare battery, but it also failed the battery test. I went to BIOS and chose reset to defaulds, but no success. I don't have the Windows-7 installation disc and the Compaq recovery discs don't help.
