Acer Aspire V17 on the Newgate_SLS MB N16E 448.06A26.0011

[magicpc]

Hello, I have an Acer Aspire V17 on the Newgate_SLS MB N16E 448.06A26.0011 board. The laptop after the turbulence related to the power supply works only on the power adapter and does not charge the battery.

The battery gives a current of about 14mA, on the battery connector I have:

1-3 - 0V
4 - 3.3V
5 - 3.3V
6 - 0.290V
7 - 12mV
8 - 10 - 141mV

Layout from photos:
Red - 141mV
Yellow - 19V
Pink - 15mV

The coil next to the battery socket is 1.7Mohm and 141mV

Where to look for the problem? Do I actually think the problem is in the layout in the picture?

Link or post the schematic but only in the schematic forum.

Share the top side markings of this mosfet.

Remove all power. Meter in resistance mode.

Measure the resistance across the mosfet pins.

Source (1-2-3) and drain (5-6-7-8)
Source (1-2-3) and gate (4)
Gate (4) and drain (5-6-7-8)

Post each measurement and the meter scale used for the testing.

I replaced the above chip and now on the battery slot I have:

1-3 - 0V
4 - 3,3V
5 - 3,3V
6 - 0,290V
7 - 10mV
8 - 10 - 18V

measurement:

Source - drain - 0.530Mohm
Source - gate - 1.3Mohm
Gate - drain - 1Mohm And rising.

Each pin had the same value, so I didn't specify it. Auto range on the multimeter.

Resistance on the old system:

Source - Drain - 0.400 Mohm
Source - Gate - 0.230 Mohm
Gate - drain - .0450 Mohm
