Напряжение питания + 20В

ID источника измеряемого напряжения по отношению к земле: 3.15V


При нажатии на кнопку выключения привел власти в течение нескольких секунд и выходит вскоре после

Не наблюдалось никаких компонентов с тепловым

Даже с учетом аккумулятора, индикатор батареи не горит

In "ingleze"version,please,dear eletmoraes...

Working only with the motherboard + CPU + memory + keyboard, AC adapter and battery. The Notebook by pressing the power button (which is on the keyboard itself) provides no image on the LCD screen and not the external monitor and also the LED that indicates that the battery is connected is off.
The source AC adapter is plugged in motherboard and when I press the power button, the LED lights up only the power for a few seconds and turns off soon after.

There are no signs of overheating components.

v + supply voltage is 20VDC
Voltage ID (control) of the source is of 3.15VDC measured with respect to ground

No picture on the LCD screen and the external display also



Checked voltage at pin 27 (LX3) of the MAX8734 is 3V15

Checked voltage at pin 15 (LX5) of the MAX8734 is 5V

voltage (+15 V_SUSP) was checked and confers
