hp probook windows 10 password reset tool

I noticed once idle in the bios, the machine is not reading or writing to the chip. Presumably what happened was the laptop loaded whatever settings it wanted from the clean image, and stored them in RAM.

After making a selection, we're now back in the BIOS, with no password, and we've got all of the original IDs! From here I'd suggest doing a security and settings reset, and then updating the bios to the latest version. Now that we've got the original bios back onto the chip, but have gotten past the password prompt by using the other bios, all we need to do now is save and exit After rebooting, we're greeted with this confirmation. And open the original bios image we grabbed from it at the start, and flash it back onto the running machine, where it will auto verify. And now we close the machine, still running, and put the clip back on. Now that we have a clean image, (with the wrong ids and stuff) we can disconnect our clip and boot up the machine into the BIOS settings.

Its not hard to find if you understand how to use google. And then we flash a dump from an unlocked laptop of the same model, I found my image online. And saving the image as the last four characters of the serial (helps me keep track) Once we have a good dump of the machine's bios, we can erase the chip. Hitting autodetect to make sure I've got a good connection Reading the contents of the chip Verifying that what I grabbed matches the chip. So I unplugged power, and set it down, connected my programmer, and opened up the software. The first step was to dump the bios from the machine. We'll also need a dremmel or sidecutters to nip out some plastic on this particular model to gain access to the bios chip. About to give up, I tried something crazy, and it ended up actually working! What we'll need is a CH341A programmer and a clip that allows me to clip onto the chip without desoldering, this setup is popular with Coreboot users. I couldn't just dump the image from a clean unlocked machine on here, because then the UUID and serial would all be changed to the clean one's image. I was unable to unlock them with any tools, and dumping the bios was a lost cause, since the machine scrambles the bios contents on every power cycle. I figured the forums would be interested in such an odd technique- So my job has like 100 HP Probook 6570B's in storage, but they were all bios locked.
