This past year I’ve been checking local listings for used cheap laptops because it’d be neat to have a small portable Linux machine.
It’s just surprisingly difficult to confirm what specs a given model has or to find reviews for it. The sellers don’t always do the best job listing the components and googling the model numbers may not give you too many results either. Some manufacturers keep reusing the same model name year after year so you have similarly named computers with wildly different guts, or often a specific model number will only give you very local and very limited results which makes me think some SKUs are only sold in a few countries for a short period of time
Buying phones is much more simple in this regard
The manufacturer says that if a bios is locked by a password, you’re supposed to replace the motherboard.
One time I bought a Thinkpad laptop with a locked bios for very cheap. The bios password was stored on a rom chip on the motherboard. When the computer booted, I pressed a screwdriver to the pins on the password rom chip to make it unreadable. Then I went to the “set password” screen on the bios, removed the screwdriver, and set a new password.
The bios couldn’t read the bios chip because the screwdriver interfered with the chip and the bios thinks no password is set. When I told it to write a new password, I removed the interference so that it could write to the chip.
After I had set a password, the bios allowed me to remove the password by typing the password that I had set.

Might not work on newer laptops.
Wow! I had never heard of this. Bookmarked for when I’m feeling up for pulling apart a laptop again. Thank you so much!
