Not sure if the Chinese have figured out a way for the newer ARM-based ones yet (I realise it's already been several years since the M1 was released...) but I believe most of the older x86 ones have been cracked.
I've unlocked some old Thinkpads that were similarly left locked with a BIOS password by departed employees, officially not possible, but actually possible if you reflash the BIOS and EC ROMs.
Thanks, that gives me hope - my SO bricked their Thinkpad by forcibly powering it off in the midst of the firmware upgrade of all things. Don't ask.
I was looking for the flashing hardware around here, but i should probably peek on AliExpress :)
A CH341A-based programmer with the accessories ("chip clip" cables and adapters) is available on AE for cheap (~$10) and will work to read/write the main BIOS.
If you need to recover the EC, then I believe anything that can work as a generic JTAG device, like an FX2LP dongle (~$5 or less, and useful for other things like a logic analyser) will also be needed.
Thank you!
