MS-14C4 unusual chip

[kalemaroni]

This laptop was brought in with no power and had been worked on in another country and they hadn't been successful. The battery and CMOS chip was disconnected.

I plugged it in and checked the thermal camera and one chip (TPS62134CRGTR) was glowing near the battery connector. I removed the chip only to find that it looked like it never belonged there in the first place. Is there something I'm missing here or has the previous shop replaced a completely different chip?

looks like they replace it with a different chip.... maybe it's a 3v-5V buck converter like TPS1225 or equivalent

Thank you both, I'll give that a go.

Before soldering a new tps1285, measure resistance to GND on 3V LDO and 5V LDO pin so as not to fry the new chip.
