Question about IBM ThinkPad R52: R52 P M 760(2.0GHz), 512MB RAM, 80GB 4200rpm HDD, 15in 1400x1050 LCD, 64MB ATI Rad... (THINKPADR52R52PM76) PC Notebook
Hi, would you know how to remove the power on password as well as the bios password as have a R52 lappy and it wont boot as its needing the power on password and i have forgotten what it is.. any help would be appreciated. thankyou. email: firstname.lastname@example.org
IBM uses a security chip on the motherboard that burns the password into it when a bios password is enabled. The only solution to getting around a bios password on an IBM is to replace the bios security chip or the motherboard. I've wrestled with this before, and believe me when I say it's a whole lot easier to replace the board. Do your best to remember!!!!!!!!

When you boot up to the log in screen type in administrator as user to log in if you cant log in
during the boot up process you will see on the screen for a short amount of time press a certain key to enter set up press and hold that key during the boot up process to enter BIOS scroll down to set user password or supervisor password you can change or remove your password from there also
The most common way that most of us know on how to reset or clear the BIOS password is to physically remove the power from the computer by disconnecting the power plug and then removing a battery for 30 minutes from the motherboard. Another way is to reset the clear CMOS jumper on the motherboard itself. Both of the 2 methods mentioned works because most motherboards use a battery to sustain the BIOS/CMOS settings for the motherboards PROM chip. So by cutting off cmos the battery power, the BIOS/CMOS settings will be erased. Hope this helps
