    Dear Expert, I would like to know how to unlock BIOS password for IBM/Lenovo laptop - my laptop was little issue in its fan (Fan error) thus replaced it and once try to Switch on the laptop - it is asking BIOS password to go for set up screen or OS. The reason showing in the Laptop is "Error code - system tampered with"

    How to solve the issue since it is not accepting even old password of BIOS? Do I need to change mother board or dispose it though I tried via CMOS set up?

  • Thanks Muntasir for Reply, I tried this way prior to posting question here but it is not working as such, thus asking for any other option from expert or do I need to replace the mother board or just scrap the laptop? If we go to its customer service they asks money more than few thousands to do so.
