Have an R9 290 I'm looking at. Seems I don't have a PX_EN. What should the voltage level typically be for this signal? What is required for the GPU to give this signal? Thanks

Hey guys.
Need help with this one.
Fan not spinning due to missing PWN Fan signal.
Also 5 seconds from powering up it freezes, unless in BIOS.
But as soon as Windows starts to load, it will freeze.
CPU is COLD / Room temp when it freezes.
I've replaced the CPU, same problem.
Replaced SIO/KBC IT8987e and reprogrammed - same problem.
Replaced fan - same problem.
Replaced flex cable from board to daughterboard (which has fan connector on it) - same problem.
Checked the Thermal sensors around CPU and Board to the SIO/KBC and...08-19-2024, 05:22 PM -
I have MSI mpg b560m bazooka motherboard . this motherboard RSMRST# signal missing . i already reprogram bios but same condition
My Motherboard this power stages are ok ...but 3vsb voltage have 4.17v (image added)
VCCRTC ok
RTCRST# ok

PCH_VCCIN_AUX ok
RSMRST# No voltage
this all voltages are ok but RSMRST# voltage is missing i did try to re program bios and change io but same... -
Hi everyone, I hope you are having a good day.
I have a laptop sony Vaio, DA0HK1MB6E0, MBX-247. REV: E
The laptop suddenly shut down as the owner told me, so I did the normal check there is no short but the laptop it's not powering up and there is no light when I connect the adapter because there is no battery.
so I checked.

Vin: 19v
Ldo: 4.89v

Vcc: 4.89v
Vdd: 4.89v

10th generation hp laptop(LA-G07FP motherboard) missing ACIN signal.charger light not blow.when pressing power button, only 3 blinks display on dc adapter bulb(only once).but not turning on.original hp charger attached.charging port perfect.
19v (gate 25v) main power rail ok
RTC section ok.
3vldo ok
5vldo ok.
ECON missing.no 3v and 5v always voltage.
REGN,ACDET perfect.but ACIN missing.No short in ACIN path(good impedence)
Replaced the bq24725a charger ic.but no result.still ACIN not generating.
is this sort of error occurs from... -
Hey fellow Badcappers
I am troubleshooting Surface 7 board (rev 1.0) which was working great until it experienced a short circuit due to a bad screen.
Now it's missing SLP_S3 signal. Everything in the power on sequence works properly up until that signal.
- The resistance to ground on the SLP_S3 line is >50 kOhms.
- No shorts on any powerrails that I can find.
- I get a proper clock signal on the RTC crystal (XTAL_2P) once the Surface gets power.
- SLP_S4 is, suprisingly, present, but it looks very weird (jump up to 2 V for about...
