SOLD! You hand over the money and race home to Google search for all of the updates to your currently outdated software.

THE «ANSWER TO YOUR PROBLEMS»
For the sake of the scenario, this tutorial will follow the steps needed to reset the BIOS Admin password on a HP Probook 430 G2, although this same method applies to ALL HP Probooks & Elitebooks. The only difference being you will need to find a clean bios.bin for YOUR OWN EXACT MODEL to be used. BIOS binary absolutely CANNOT be used for ANY other model besides the intended device. You may use this guide as an outline for what you will need to do, but if you don’t have specifically a HP Probook 430 G2 then you will have to provide your own BIOS dump. If you are unable to find one or would just rather not deal with the hassle then send me a PM or Email and for $10 I will find you what you need.
- Take off the back to plate your HP laptop and look for the 8-pin chip that you are going to clip in to. If you don’t know what you’re looking for then take a look at the pictures below for an example. Once you’ve found the chip write down the model number displayed on the top of the chip. With your model number in hand, do a Google search to find your EXACT chip’s datasheet.
- Skim through the datasheet for the specific voltage setting on VCC (Pin 8) of the chip. Newer HP models have the voltage set as 1.8 v-v 2.0. If your model requires 1.8-2.0 v then you absolutely will not be able to proceed until you are able to supply EXACTLY the required voltage. (If your HP requires
3.3 v-4.0 v then continue to Step 3) Conveniently enough the Raspberry Pi has a spot that supplies 1.8 v. Grab a soldering iron and some solder (and most likely a magnifying glass!) and solder a wire from to the spot on the Raspberry Pi that you can connect to your SOIC8 clip. Depending on which model of Raspberry Pi you have the spot will differ, so take a look at the pictures below to see where you’ll need to make the solder point.
FOR ORIGINAL RASPBERRY PI
FOR RASPBERRY PI 2 MODEL B
flashrom -r /path/for/your/bios.bin -VVV -p linux_spi:dev=/dev/spidev0.0
flashrom -E -VVV -p linux_spi:dev=/dev/spidev0.0
Write your test-bios.bin onto the chip.
flashrom -w /path/of/your/test-bios.bin -VVV -p linux_spi:dev=/dev/spidev0.0
Verify the image has been written correctly.
flashrom -v /path/of/your/test-bios.bin -VVV -p linux_spi:dev=/dev/spidev0.0
And reboot your HP!
