Hi everyone,

 

I tried to start ma laptop but the screen stay black and the front leds are blinking on this sequence:

 

- Wi-Fi, drive and power (in the same time) blink in white (1 time)

- Charging blink in orange (1 time)

- Charging blink in white (1 time)

- Charging blink in orange (1 time)

- Charging blink in white (1 time)

 

I tried to find which error code is it and how to solve the problem but I didn't find nothing.

 

Is someone know how to solve this issue?

 

Thanks.
