[Blank Screen] LCD Problem or Another Hardware Failure?
テキスト:
Hello!
I've Lenovo ThinkPad T470 with blank screen LCD.
When I short press Power button, the step is like this:
* Fan is running
* Green LED on Power Button is Light Up
* Keyboard Backlight is Dimmed
* Red LED ThinkPad on LCD cover is Light Up
*
* After a few second:
* Fan is stop
* Green LED on Power Button is still Light Up
* Keyboard Backlight is off
* Red LED ThinkPad on LCD cover is Light Up
* LCD black screen
* No beep sound
