For HP 15-ec00 DA0G3HMB8D0 REV:D Quanta G3HA

[rs2pac]

Need help finding schematic / boardview

Notebook: HP Pavilion Gaming 15-ec0063
Motherboard info: DA0G3HMB8D0 rev
Platform: QUANTA G3HA
Motherboard Part Number: L71929-601
Notebook Part Number: 9MT23PA

The device works fine, but the USB 2.0 and HDMI output does not work. The power button&USB board is damaged. The USB charging port power switch controller is completely dead.

Thanks.

USB load switches get damaged all the time. They are electronic fuses and should turn off the Vbus rail with an excessive current as the trigger.

However, some of the load switches are crapware designs and they just die.

Post pics of the USB connector that does not work and nearby, there should be the USB load switch. They are very common to source from real branded companies.

Datasheets are often with the same pinout so you can confirm if this is the fault or not very quickly.

Ok. Please help identifying the chip. I would be very grateful

Very difficult to read the top line - can you post a pic of the bottom side of the IC ?

Looks like that the IC has been removed off the board ? So also post a pic of the SMD pads on the logic board so we can understand the SMD package of this component.

Looks like a QFN-16 package.

Re: For HP 15-ec00 DA0G3HMB8D0 REV Quanta G3HA

yep. its QFN-16
IC still on board. The laptop continues to be used for work.

There have already been hints that this is an analogue of the TPS2540 and perhaps the SLGC55544CVTR or SN1702001RTER will do.
That's why I was looking for a schematic / boardview to make sure. HDMI worries me. Will it work after changing the IC.

I was going to make a separate topic in the repair thread. With a full description of what happened and put these photos there. Also complete the following solution. An additional problem with HDMI.
Leave this schema request here. The platform is widespread and this motherboard was installed on 25 different laptop models from HP. There is also a list with all numbers. I hope the diagram and information will be useful to someone.

The IC is linked to the FPC connector on the right side of the daughter board.

What is this FPC connector used for ? Even with the top side being damaged, the FPC connector is working with the connected circuit ?

Re: For HP 15-ec00 DA0G3HMB8D0 REV Quanta G3HA

The train (FPC) goes to the motherboard from below. This power button board itself and also USB 2.0 on it with power support.

P.S. on the picture, the battery connector is disconnected before the first visual inspection.

Re: For HP 15-ec00 DA0G3HMB8D0 REV Quanta G3HA

Case history: The laptop is turned on, and the FeiyuTech-G3Ultra gimbal (3-axis stabilizer) was safely charged in the USB 2.0 port, in the OFF state. After turning on the power, this connected stabilizer, the laptop turned off (it went out completely), but did not die. In the future, it was launched, loaded and still works. However, part of the hardware does not work. That USB 2.0 died, HDMI stopped working (although the second monitor reacts that something is connected, sorts through the inputs, but does not show). USB 3.0 works ok.
Later it turned out that the FeiyuTech stabilizer should be connected to the PC ONLY via an adapter (USB TTL), but the pinout is not pure TTL, but a proprietary modification (there are only three wires), rather signal ones.
Something like this.

Where to source these ? Really impossible to get them here in India. ANy alternative solution for this chip ? Water damaged and this IC is burnt. Laptop is turning on with no display.
