Removed from a laptop with cosmetic damage and deemed uneconomic to repair Board powers up and boots into windows perfectly fine and has no bios passwords This is the i5-7300U board ALL DELL BOARDS NEED BOOTING SEVERAL TIMES TO BOOT UP CORRECTLY AS THE BIOS GOES THROUGH SEVERAL CHECKS FIRST AFTER BEING CONNECTED WHEN NO BIOS BATTERY OR BATTERY IS CONNECTED, SO PLEASE DO THIS BEFORE THINKING IT DOES NOT WORK!
