Question about IBM ThinkPad 570 Notebook
If you have forgotten your BIOS or system password, there are no software tricks or magical gimmicks that will get the password cleared. Laptops are different in that they are designed to not work with “backdoors” etc. for security reasons. There is one true way that works most of the time and that is hardware.
The Cmos (RTC) battery that is mounted on the motherboard in most cases holds the key, if your motherboard has the battery that is connected to the motherboard by using a two wire socket that plugs into the MOBO, then here is the procedure.
On the motherboard where the battery plugs into, you will see two pins sticking straight up, these engage the plug on the battery side. These two pins have to be “shorted” and then the motherboard powered up for approx. 30 seconds, then power down the system and replace the Cmos battery and reboot. Your password problem should be cleared up. The best way to “short” the pins is get another cmos battery and cut the wires from the battery part, bare the ends and twist together, this will short the pins. Make sure you tape the connection good on the jumper you just made….don’t want to touch anything else with powered up bare wires. Good luck.

For that you need to reset factory defaults settings for bios.
For reset bios u have to open back side of your laptop then u find motherbord circuit there.
pull cmos cell on motherbord for 15 minute then it reset to defaults.
Also u can reset with jumper settigns read carefully on mother bord there is 1 jumper near cmos cell u read there " bios reset or clear"
It is on 1-2 position right now set it in 2-3 position then power up then all bios settings are reset.
then again set it in 1-2 its original position.

none of that basic stuff work on late thinkpad. solution.
flash/replace bios chip
build dongle to read bios chip using xternal monitor
all require an expert or parts and soldering skill
u can get the replacement on ebay about USD14-15 and i show you how but you must be able to solder
could also send you one but would take a little while i'm in jamaica

You'll probably need to take it to a reputable repair person or check my website www.micromend.com. The reason is that a program such as ERD Commander needs to be used to eliminate the password and then to restore the laptop is a 10 cd set with Windows and all the drivers. Good luck
