Samsung Galaxy Book S

[reformatt]

Model number is SM-W767. This unit is dead. Posting this here as a footnote for future ref.

Charging is via USB-C. Supplied adaptor says its either 5V or 11V via PD. When connected, it draws 5V @0.52A. This doesn't change regardless of whether the battery is connected or not. There are two USB C ports, both exhibit the same regardless of plug orientation. Thermal camera shows something getting hot in the middle of the board (appears to be on keyboard facing side), which I suspect is the PMIC. No fan, all cooling done with a large copper heatsink.

Might just be a shorted cap. But I didn't go any further with this, as the unit is still under warranty (in Australia we get 2 years under Australian Consumer Law). This unit cost $1800 and just seems like a giant phone. No parts, no service manuals, no support. This one will go back, get a motherboard replacement, and he'll lose all his data.

Can't say I'm a fan of anything Samsung make. And this just reinforces it.

Stuff fails regardless of the the age and name, it's a reinforcement of always backing up what is important.

Re: Samsung Galaxy Book S

Well it turns out the customer was BS'ing and the unit is over 2 years old and out of warranty. So I was asked to take the board out and see if I could see anything obvious.

The board is single sided. It appears that Samsung do not intend this board to be repaired, as the bulk of the components are all hidden under soldered metal shields. Area of interest was under shield marked 587, which I presume to be where the PMIC is located. With what was accessible, it seems there was a short somewhere around the diode on the extreme RHS near the connector for the SIM/SD card slot.

No schematic so it didn't seem a profitable job to take off the shields one by one to track it down. I don't know if you can buy boards for these from Samsung directly.
