Thank you all for looking at this. This laptop was a bit of a learning experience. As I am sure some of you know, laptop makers give bios codes on the keyboard lock keys. This HP is flashing its Caps and NumLock 2x, according to this (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01443366&lc=en&cc=us&destPage=document&dlc=en&lang=en&product=3816592&rule=26781) means corrupted BIOS. Now the laptop is a DV5Z-1000. I then found http://forum.notebookreview.com/hp-compaq/304332-c700-cq40-cq45-dv4-dv5-dv6-hdx18t-insyde-bios-recovery-using-usb-thumbdrive.html that tells how to flash the bios on a non posting sytem. (essentially take the bios file, strip off the rev., name it a bin, put it on a flash, hold win B, plug in and power up w. no battery.) , here is where I think the problem is, I don't think I am getting the right BIOS. By putting in DV5Z-1000 I get a CTO laptop. If I take that BIOS, and rename it to 30F2.bin or 3622.BIN the laptop will BEEP, access the flash drive, BEEP some more, then 'restart' with more numlock capslock flashing...

Again I think i have the wrong BIOS or wrong name for the BIOS in the flash drive. Has anyone flashed a BIOS to an HP in a situation like this?

Thanks in advance!

Not done an HP lately but I have done an ACER and had to call it BIOS.FD?

Try that extension rather than .bin

Have you tried following the Acer method?

I have tried it with a .fd extension. I will try calling it bios.fd tomorrow.

Thanks!
