RCUnlocker can delete computrace lock? Sorry, this is my first time encountering this. The laptop was blocked for organization; the laptop was scrapped. I was able to fix it, it did not turn on, but I see a blockage when installing windows.

Many thanks to you. With the help of your dumps and BIOS Configuration Utility (SP100599), I won the battle with Windows Autopilot Lock. Everything works fine!

the product number is extracted from your bin. upload the EC 16mb or use RC unlocker D.I.Y .
did you verify this main bios bin after reading?
ec is found at the back of the board you need to disassemble.

Please help me to remove BIOS password from attached dump (32MB). Patching this dump - as rex98 did in 274 - would be the best.
