Hello,
A complete beginner here so I am sorry if I say or ask something stupid.
Recently I wanted to upgrade to Windows 10 on my Lenovo ThinkPad T450s 20BW. When I tried to access the BIOS settings I realized I need a supervisor password to access BIOS. I don't have the papers that came with the laptop and I don't remember the password. If I just press Enter I can access the BIOS settings but many options there I can't modify. I read somewhere I can try to unplug the CMOS battery and regular battery. After trying that I am in even more trouble because now I have Error 0271 - Check Date and Time Settings on the screen when I turn on the laptop. I spoke to Lenovo support since my laptop is still under warranty but they want to replace the motherboard which is insanely expensive. I was told my laptop is a newer generation of Lenovo laptops that store the supervisor password differently comparing to older models and resetting the EEPROM chip using jumper method will not work. I was also told the supervisor password can be recovered or reset with the help from the people here if I have the dump from the BIOS chip.
Anybody here can help? Willing to donate if my laptop is fixed.
Thanks in advance.
