Question about IBM ThinkPad T40 2373 Notebook
As many as three passwords may be needed for any ThinkPad computer: the power-on password (POP), the hard-disk password (HDP), and the supervisor password (SVP). If any of these passwords has been set, a prompt for it appears on the screen whenever the computer is turned on. The computer does not start until the password is entered. To remove a Power On Password that you have forgotten, do the following: 1. Turn off the computer. 2. Remove the battery pack. 3. Remove the backup battery. 4. Turn on the computer and wait until the POST ends. After the POST ends, the password prompt does not appear. The POP has been removed. 5. Reinstall the backup battery and the battery pack. Now the bad news, if the supervisor password has been set then this procedure will not work and if this password is unknown the the whole system board must be replaced! Secondly the main battery removal is easy as you just need to unlock it with the slider you see on the base of the unit and slide it out, BUT the backup battery is inside the laptop and to get to it you need to remove the hard disk drive, the keyboard & the palm rest. If you haven't taken a laptop apart before this is quite a daunting task. However, there is a very good hardware manual with clear diagrams available on the link below so take a look on page 29. ftp://ftp.software.ibm.com/pc/pccbbs/mobiles_pdf/39t6192_01.pdf If you don't feel confident then maybe find a techy friend or local shop to help. Please update the question & let us know if the information given was useful to you - Good Luck!
