Re: Problem with thinkpad x250

Problem with x250. On the original bios, the laptop flashes the LED 3 times when the power supply is plugged in. After pressing the switch, the laptop turns on for one second. On other bios the laptop starts up with no picture and gives 4 short beeps from the speakers, the keyboard lights up and when you press the spacebar the brightness of its backlight changes. Please help

Many thanks hoaca388 BIOS works great. All the rest of the strange behavior of the laptop is a broken keyboard and unplugged connector from the screen.
