Unablet to boot: white led and poer button blinking alternatevely

[Ciro_28]

I tried to boot the computer this morning but it won't turn on. When i press the power button it starts blinking together with a period of about 5 seconds with the wifi and the mute lights. Immideatly after the power button turns of the led light near the charger ports turns on and stays on light for 2 seconds. If i plug in the charger the white light near the charger port blinks indipendently stying on for 5 seconds, turns off and immideatly on again.

I looked for similar problems in the comunity and tried to emulate their solution:

• I unplugged the battery and the charger, pressed the power button for 20 seconds and then plugged the charger only. When pressing the power button but all the situation descried repeats itself. 
• I tried to unplug and plug again pressed win+B for 4 seconds and while that pressed the power button, but the results were the blinking lights described.

Please someone help me with this.
