When I turn on my computer I see the initial thinkpad screen then I get two error messages that read:"Error0182: Bad CRC2. Enter BIOS Setup and load Setup defaults."and.."Error0191: System Security - Invalid remote change requested."I tried to reload the setup defaults; however, in the BIOS Setup Utility menu, I try to highlight this option and it doesnt allow me to select it. Any suggestions are greatly appreciated.By the way as a side note, I was given this computer by my school so Im suspecting this is why I cant reload the setup defaults, but im uncertain.
