Thanks, but i thought about instruction how to recover bios in inspiron n5110 after bad bios update. Maybe there is special key combination or something else? I asume that have to plug in usb with bios recovery files and then boot my dell, but should I press any key to start bios recovery mode?
Bios recovered: 1: Create bootable usb flash 2: remove battery and power cord 3: plug the USB in 4: Hold-down "END" key about 3 second, then plug powder cord in and release "END" key. 5: If power LED lights read and Fan full speed, it seem good. Then, the power LED and USB LED indicator start flashing mean the recover process are working. The laptop will restart itself. "
