Question about IBM ThinkPad T20 2647 Notebook
How to unlock screen a lock is on it and I do not remember password it gives me 3 tries
Posted by Anonymous on
Screen password...... There are 3types of passwords that can be set on a thinkpad.
- Hard drive password
- Power on password
- BIOS/ CMOS password
Of these 3 only the third is recoverable or changeable without a lot of tinkering and disassembly. By removing the battery, power adaptor and the cr2032 battery inside the laptop for 1 hour then replace and the password should have cleared.
password 1. You will need access to the HPA area of the hard drive and a few lifetimes of manuals and knowledge to get the password backif it's recoverable or even accessible.
password option 2. You will need to find the "Atmel 24rf08c" EEPROM on the laptop motherboard and then EEPROM dump it's contents then scroll down many lines of code until the password appears on the right hand side.

The IBM Thinkpad has a very strong security system.
If you are seeing a lock symbol when booting then somebody has set the supervisor password. If you can't remember it or guess it (try "password", "admin", "pass", etc) then you need to find the person that set the supervisor password.
Once the supervisor password is set the T41 is very well protected and it can't be reset by removing the laptop battery or CMOS battery.
There is a way to read the password from the protection chip but this is very complicated and requires taking the laptop apart and building your own chip reader.
The instructions for doing this are are:
Hope this helps,
