Yes, that's right. Only way how to easily clear the password here is to rewrite bios chip.

In these models is a 8 pin serial flash.

You can download a bios update on HP pages. Start a setup on any laptop and althrough it would tell you that it's not the right computer where to flash it, in /SWsetup/... directory will be a full bios .BIN file which has 1024KB.

You should have some programmer to flash it in the chip. It's without a security zone so after flashing it the serial number, service tag and all things like that will be clear.

enjoy it, I had it finished in 20 minutes.

It's a flash ROM. I can't tell you exactly what chip was used, there are many equivlent chips and even in the same model you may find different chips.
If I could see a plain picture with mainboard I or a forum member could could point you in the right direction.

You know how to do it with this chip?

victor · S.F. Boss Joined: 07 Mar 2004 Posts: 2581 Location: Staff

You have to reflash that. with a fresh BIOS code. that's what you have to do.

Do not short onboard chips, even if they a classic i2c eeproms like in Dell's, never do that! That is a dumb idea came from someone that supposelly has never seen nor operate an eeprom programmer in his life..

Hi,

About nc6320 power-on password :
i reprogram a chip(mx25l8005) that I bought on ebay and i've soldered on(the original chip when i try to remove it from notebook motherboard : i broke a leg) and it's working well.
