I browsed eBay and some other sites yesterday and I noticed that locked thinkpads are cheap as fuck and have i5 or i7 processors for just 150$.
Isn't it possible to temporary remove the CMOS battery and to reset the bios password?
Or did lenovo fuck up and did some shit to prevent this?

nope

Why not? Where is the problem?
removing the cmos battery doesn't wipe a bios password on a thinkpad. *some* models can have the password wiped of certain points of the mother board are shorted during startup. it can be pretty involved
As long, as you have hot air gun and stack of BIOS ICs - it probably worth it
Do you know which models?
So I have to remove the whole BIOS chip and replace it with a different one to remove the supervisor PW??
no, because i don't buy thinkpads with bios passwords. aint got time for that shit
You can save a lot of money.
Thinkpad with an i7 4xxx processor and 4 gigs of ram for just 130 bucks is a good deal
my [used business grade laptop] was $100 and didn't have a password, and i didn't have to buy equipment to safely remove the password, or spend the time doing it, or fuck up doing it and damage the board
lol and it had an i5-3320m which is 5-10% faster than a 4th gen ulv i7
Wrong, but practically right.
user, you need a specialised soldering tool unlock it. The bios password is saved to flash memory on the motherboard and is non-removable and has its own batter.
Thinkpads are business laptops, their bios passwords aren't easily reset like the majority of the trash out their to protect files on the HDD.
A mate stumbled upon one once which I gave a crack at but still couldn't manage.
>Isn't it possible to temporary remove the CMOS battery and to reset the bios password?
No, but you can collect the password with an arduino.
I'm listening...
>Wrong, but practically right.
so i can take the CMOS battery out and the password is cleared? or is your reading comprehension off.
Can't you short that chip?
How?
yes
it takes literally less than 10 seconds and can be done with a screwdriver titled at an angle
Can you somehow disable computrace though ? Because BIOS password never was a problem.
thats not even cheap. working ones cost about same unless overpriced
what if you flash coreboot to it? no soldering needed and original bios botnets should not work.
Don't you need access to BIOS to flash it..?
only to the chip. you need a hardware flasher to install it
What if I can boot with the locked BIOS in windows and upgrade the bios with the official BIOS flasher from lenovo? Will the pw be gone?
No this isn't something utilising the cmos battery you fucking clod
>reset the bios password?
In most cases, you can't.
No, at least not on a modern ThinkPad. The PW is stored on a separate non-volatile chip.

If it's a 40 series or newer you have to pay $60 to a romanian jew to unlock it.
So you want to tell me that a Thinkpad with a bios pw is just useless hardware and cannot be used?
no they are very useful once you remove the password. you can just search for it and find instructions for doing it.
bios-pw.org
They're all backdoored.
Have fun!
They aren't. Thinkpads for example don't give a code but a message like "wrong password"
Yeah and there lies the problem
