Hi everyone,
I've got ThinkPad T450 with the following symptoms:

After pressing power button:[LIST][*]The power button lights up and stays lit for ~20 seconds[*]Fan spins up immediately and spins for ~7 seconds[*]Keyboard Lock buttons flash and then go dark[*]Display goes from transparent to black within 3 seconds of pressing the power button and then goes to transparent again after the power LED turns off (panel shows no image, backlight is off)[*]With VGA monitor I get no output either[/LIST]I tried:[LIST][*]Removing RAM from socket - this gives me 1-3-3-1 beep code as it...

Hi, I'm Andrew from Czechia. I study IT and I like to repair my own stuff
