voltage on the on-off touch switch with 0.5V . Processor with cold temperature . So far I could not find the notebook's electrical scheme which would be of great help if I could find . So far I have not found any warming in component .
voltage at the DC input with 19V .
It would be of great help if I could find the schematic diagram of the notebook

Describe in more detail what measurements were made and where?


Check the voltage on the power coils, check the power EC-controller (kb9010).

Reprogram the EC-controller kb9010 (BIOS) or replace.


Replace processor.

1 - Charging coil.

2 3.3 V and 5 V coils along with your Mosfts and PWM.

3 coils vgfxcore and vcore.

4 1.35 V coil that feeds memories.

5 charger and its mosque.

6 I believe that they are the source of PWM and the source of MOHETA.

7 I believe that this is PWM and scammers from the vgfxcore source.

8 MOSFET with 1.35V memory.









1 - charger coil. Voltage: 2.60 V

2 coils 3.3v and 5v along with their mosfts and pwm. Voltage: 5.08 and 3.34 V

3 vgfxcore and vcore coils. Voltage: 1.091 and 1.69 V

4 1.35 V coil that feeds memories. Voltage: 1.36 V

5 charger and its mosfeta.

6 I believe that they are the PWM and MOHETA source vcore.

7 I believe that this is PWM and mosfets from the source vgfxcore.

8 Mosfet of memory 1.35v power.

I managed to find the defect and the problem friends. I just replaced the power cord that came with the DC connector on the 19V power supply. According to the attached image.
