Re: HP BIOS unlock tool

Only battery. Cmos battery is not related.

Verify means that chip is read twice and content is compared. If they match, it passed. Usually software has verify built in but you may need to do it...

Re: HP BIOS unlock tool

Andrews, could you post your files? I found one low end model which had totally different bios and it might be the one you have. My unlocker won't work on that. I could check that if you upload...

Re: HP BIOS unlock tool

Method depends on what you use for programming. With some programmers it works differently. I am not sure there is a reliable method for Ch341A.

But on most of my programmers I do this.

Re: HP BIOS unlock tool

wThere should be only 3.3V and 1.8V versions so you must be confusing something.

You get 5V from USB but there is a 3.3V regulator on board thus your chip gets 3.3V. To use a 1.8V chip with that...

Re: HP BIOS unlock tool

I always use clip because I know how to do it with no issues. But unsoldering has less issues if you don't know everything yet.

To get to the chip you just need to remove bottom cover, fan and...

Re: Panasonic touchbook cf-53 mk2/mk4

You can dump part of the bios like that but it is useless on this model. Password is both obfuscated and encrypted. You can't write back modified file using software tools because bios region is...

Re: HP SpareKey issue with my HP Spectre x360

I don't think HP sets any passwords. Only on demand by whoever orders these laptops. I just read it from your bios dump.

Re: Medion Akoya MD 60450 E6432 bios password

No. Why should it? Upload your own bios dump and we can read the password from there.

Re: Panasonic touchbook cf-53 mk2/mk4

You mean from pressing power button to displaying a logo takes time? Cleaning ME region should fix that.

Re: Panasonic touchbook cf-53 mk2/mk4

Re: HP BIOS unlock tool

Mazzif did not list 2570p as supported. He even said that xx70p is not supported.

So you have to read, modify and flash. This tool works on this model.

Re: HP BIOS unlock tool

On newer models, it seems you need to remove it in EC aswell. I still haven't seen any newest models so I have not tested it myself.

But otherwise, the method seems to be same.

Lenovo Yoga X1 Gen 1 bios black

Has anybody experienced this issue?


It boots fine, there is image. But as soon as I enter bios (F1), it just stays at black screen. Same issue with about 10 machines.
