      5VAO is an always on voltage. Remove all power and post resistance to ground measurements for PSL8101 .Do you have a boardview, and do you have a DC lab power supply

                              Asus VivoBook F510UA-AH51 won't run on battery after motherboard replacement
                              by dhenion
                              I'm working on my sister's laptop: Asus VivoBook F510UA-AH51 - The motherboard died so I replaced it.

                              The original board was:
                              ASUS X510UNR REV 3.0 A

                              The replacement board is:
                              ASUS X510UNR REV 3.0 B (identical except B vs A - I couldn't find an A board anywhere. Visually they are identical.)

                              It boots right up on the replaced motherboard and everything works fine on the new motherboard - but it won't run off battery. When I disconnect the charger it immediately dies. When I plug it back in and reboot the system - it still shows the battery at...

                              ASUS P5GC-MX motherboard recap
                              by momaka
                              Here’s another motherboard that needed a full recap: an ASUS P5GC-MX.
                              This one was gifted to me some years ago by user Pentium 4, along with a few other goodies. It actually came in working order with no bulging or leaking caps. However, I noted there were United Chemicon KZG caps everywhere on the motherboard. The CPU VRM output (CPU V_core) was the only exception: it had only 2x KZG. The rest was 6x UCC TMV 4V 680 uF caps… which aren’t any good news either.

                              So here is what the motherboard looked like with its original caps:


                              CPU VRM area up close…...

                              Dead ASUS ROG STRIX X299-E Gaming Motherboard
                              by SavaBogdan
                              Hello. I am having some trouble with a X299 motherboard. I did some searches and I found very little info about these X299 chipset motherboards. It's a bit strange because they are known to be unreliable and I expected to find lots of posts. So I decided to make a thread and ask the experts for help
                              Ok, here is the info I have.
                              The board is completely dead, nothing happens when I try to start it up.
                              I stripped it down and started measuring. I have 3.3v on the power on switch pin, so that is ok. I also found 1v on a coil near the sata ports and 3.3v on the coil next to the...

                              ASUS Zephyrus GA401I Severe Lag, Suspect Motherboard/Power Issue - Need Help Diagnosing
                              by MakNCheese
                              Hi everyone,

                              I'm having a serious issue with my ASUS Zephyrus GA401I (4 years old, worked perfectly until recently). The system is lagging heavily, even in the BIOS, and is charging extremely slowly (a few percent in hours), making it nearly unusable. I suspect a motherboard or power delivery issue.

                              Symptoms:
                              • Severe lag across the system, including BIOS navigation.
                              • Slow boot times and unresponsive performance in Windows.
                              • Battery charges very slowly (e.g., ~5% in 2–3 hours).
                              • No error messages or BSODs, just extreme sluggishness.

                              What I've Tried:
                              • Replaced
                              ...
