Interesting. I've always assumed that resetting BIOS settings, including the password, is as easy as removing the battery regardless of how modern the machine is.
- sneak 5y agoThis is not the case for Macs.
- tyingq 5y agoI believe it's still that way for low-end machines. For higher end ones, there's some range of security-by-obscurity to actually secure. And a bunch of tools to circumvent, ranging from open source (like the one I referenced), hardware assisted, to pay-per-unlock services. Some high end machines also have specific solder points you can ground out during boot, but it's not shorting a battery, it's setting a GPIO state.
