AS A FINAL UPDATE:

I talked to HP Total Care and was directed to one of the highest available HP Corporate positions. I talked to a lady (who I was lead to believe was up with the CEO) and she told me that the motherboard would be replaced free-of-charge. I received the laptop and after 2 years the power input began shorting. As a last resort I purchased a power input module to replace it - which required removing the old power input and soldering the new one on - (without solving the issue) so its in the trash now. Parts have been sold and I just purchased a Dell Entertainment Inspiron E1705 Notebook.

YOU ARE A HERO!!!!!!!! Everywhere I looked and HP said you had to replace the motherboard, BULLSHIT!!!! You are exactly correct, it's under the wireless access panel on the bottom and is in a socket!!!!! I had version KD.M1.80 and tried to update using ROMPac to version KE.M1.43 and it corrupted the BIOS, machine now dead. I'm an electrical engineer with access to a prom programmer. I took the M145.ROM binary file off the floppy created for BIOS version KE.M1.45 (the latest according to HP's support web-site and just burned it in. The programmer confirmed proper data burn in, but the notebook still will power on only and do nothing eles!!! I also am looking for the older version (original), now that I have the capability to burn the flash. DOES ANYONE HAVE KD.M1.80????

Thanks
John

P.S. If I ever get this working I can reflash your chips if you have a sst39sf040 or thereabouts. You provide the binary file you want burned and pay postage both ways and no problem, no warranty or promises.

OOPS, sorry, new to daniweb, I didn't read the whole thread. I am now going to try the KD.M1.82. I'll let you know.

p.s. this ze5155 was refurbished, when running the dos version of e-diagtools, upon boot, it said "platform name: HP Pavilion ze4000"

IT WORKS!!!! IT WORKS!!!!!

THANK YOU EVERYONE!!!

KD.M1.82 WORKS ON MY refurbished ze5155 !!!!!!
got the binary file to burn using the links suggested above to get the ROMPac installer. It puts the file on the floppy as M182.ROM. I have that binary file if anyone needs it.

yes i need it 2. Will it work on HP pavilion a740.be MADE IN 2004. Could you send the download on my email or a link?

Hello,
I have same problem with ze5155 bios update.HP sent to me wrong bios version and after updating the bios my computer is booting no more.The guys in croatian service told me that they need original version of bios which is KD.M1.60 from Phoneix Technologies to reflash it.
Please if anybody have original bios,could you save it and sent to me via mail?I tryed to contact HP so many times but they are useless.
Thank you in advance.
