LG R470 Board restarts when I touch some CPU Regulator traces ungrounded

12-24-2014, 04:51 PM

Laptop model I'm working on is an: LG R470

Motherboard model is: DA0QL2MB8F0

Original problem was: laptop shutting down when Windows was starting, it had a NEC TOKIN 0D108 capacitor, I replaced it with 4 330uf SMD capactitors.

Current situation: Same symptoms as before, but I noticed when I touched for example the IREF trace of the CPU Regulator with one lead of my multimeter, the board would restart.

Try to add 1 more 330uf and don't forget to remove the rtc batt.

Asus B85M-GAMER no hdmi output and random restarts

by Prosatanosz

Hi!

Asus B85M-GAMER absolute no hdmi output (not at start, not at Windows), and random restarts. Everything work, except hdmi and random restarts after 0.1-3 min. Restarts even in bios. On VGA Windows boots up fast, games and apps starts ok. Mem, psu, cpu changed, no luck. I need shematic, because i think the restarts caused by the hdmi failure.

by bilux

Hello everyone,
I want to find a replacement for uP0109 8pins, and i found this parts:

uP0109 is "2A Ultra Low Dropout Linear Regulator"
RT9199 is "Cost-Effective, 2A Peak Sink/Source Bus Termination Regulator"
FP6137C is "2A BUS TERMINATION REGULATOR"

can replace uP0109 by RT9199 or FP6137C ?

Help identifying AMCH073 regulator or finding a compatible replacement

by taurtnt

Hi everyone,
I’m trying to identify a step-down regulator marked AMCH073. It’s used on the PEX power rail of a graphics card. I can’t find any datasheet or info online.
Here’s what I’ve observed:
• It has a QFN-16 footprint, similar to NB670.
• Pins 1, 2, 15, 16 are connected together and go to the inductor, so likely SW (switch node).
• Pin 9 is connected to GND, which doesn’t match NB670 (where pin 9 is SW).
• Pin 8 also seems to be tied to the same GND plane.
• The chip only says AMCH073, no manufacturer logo or other markings....
