Re: HP probook 640 g2 - does it self destruct with bios chip removal?
I know its a couple years later, but I have a possible theory. The HP laptops that have socketed BIOS chips are internal engineering samples. I've gotten my hands on them twice on the used market. They have Rev. B bios instead of the standard Rev. F bios most of them have. That would account for why the 1st laptop didn't work, but not the second. So I'm not sure about that. But I can confirm that the internal prototypes they use in testing do in fact come with removal bios chips. The first one I found was a 8540W with a dreamcolor screen. It had no stickers, nothing on anything, the CPU was written on with a marker. Even the case seemed hand made. I scored it off eBay years ago. I just recently scored a 810 G2 it has some stickers, it's funny the warranty says 0 years and the serial number starts with ABC and is not in their system.
