Re: HP probook 640 g2 - does it self destruct with bios chip removal?
Almost a year later, I tried my hand at salvaging it again once more.
Although flashrom reads and writes to the bios chip just fine, the laptop won't boot. In fact, it acts precisely the same way it does without a bios chip in it at all (when plugged in, the charge icon flashes, and it will not turn on).
I followed this gentleman's steps to a tee, by the way: [url]https://www.youtube.com/watch?v=vgbWtxv_hqM[/url]
I also used a .bin I got from badcaps, which I attach...

Bios chip isn't soldered on this motherboard ; there are doors one closes to lock it in place. I could take a picture of it or you.
Can you forgive a neophyte for being at wit's end? Anti theft panic feature was all I could think of.

HP probook 640 g2 - does it self destruct with bios chip removal?
Hi!
I have multiple hp probook 640 g2s that are bios locked.
I removed one, flashed a clear bios from here. Plugging it back into the laptop, it wont boot, and charging led flashes orange.
I remove the 2nd one's bios chip, which is still locked. Now they both won't boot and do the flashing orange, regardless of which chip is in which laptop.
Even the 2nd won't boot with the 2nd's bios chip, despite being untinkered with.
Could I be missing something? Is it possible these laptops are set not to boot ever again...
