acer vn7-592g runs fine on wall charger. Windows shows battery charging. Purchased 2 new batteries and have same issue. If power cord is removed, system powers off... If trying to start system on battery only, system powers on, then off again in a few seconds. Then repeats until battery is fully...

One thing i know pretty well is Ohms law. And what I was explaining is that by setting my CV at 1.1v, the system wanted more current than I had my bench supply set to. So in order to get the voltage to stay at 1.1 i had to up the current. Basically, on this power supply, if i set the current...

Dead on the money. U34 gets warm / hot when I inject 1.1v @ 0.75 amps. Any less and the CC protection would kick on and drop the voltage causing the chip not to heat up. This would point to the SuperIO, but I wonder if that chip was bad all along, or I blew it when shorting the other...

I went ahead and cut the trace. I verified to continuity through the cut. On the trace side, its a dead short to ground. On the side of PU21 pin3 I don't get short to ground.

WOW!!! Thanks for all the extra info there. That really helped a lot. No resistor on PR324 so cutting the trace look like my option... Before I do that I just want to be very clear on evertything so i don't screw more up.. lol So I'm looking for a short to ground on +3v_ALW once PR324 is...

ok... I'm sorry for this, but we need to start over. I broke something else when troubleshooting and fixed that issue, and then created another. I replaced the part i thought was heating up, but apparently the part heating was on the opposite side of the board and i didn't think to flip it...

I've been looking. Can anyone recommend a good ultrasonic cleaning solution for PCB's? An Amazon link would be great if you have one handy, but I can look up whatever too.. Thanks

I follow what you're saying now, and I understand the confusion. I got a little ahead of myself when I was writing out the numbers on CN19. Let me do this again.. Pin 1 - Ground - 0.0v 2 - Pwr ON LED - Bounching 0-3.29v 3 - PWRBTN# - 3.29v 4- +5V_S5 - 0.0v So i have 3.3 on PWRBTN# at both...

I don't expect to find 5v at PWRBTN# However I would think I would find 5v on +5v_S5PWR correct? (IDK.. If I knew i wouldn't have paid for the help on this forum.. lol) I don't think running a wire will help because the path from SW1 to CN19 is fine. Correct me if i'm wrong, but on SW1 i...

I've got the new chip soldered in, and I'm back to testing. On the board view, Looking at SW1 It has 4 pads. 2 are ground and 2 are PWRBTN#... Both PWRBTN# pads have 3.29v on them.. The actual connector with the ribbon cable for the power button is CN19 and has 4pins.. Pin1 = Ground, Pin2=...

Well I just did it. In poking around i slipped and shorted 2pins on an 8pin chip (PU11), Which I think is a voltage converter, and let the smoke out of it. I just ordered another, so hopefully i can get it swapped and keep testing. I guess I'll be back in a few days... lol

I will check if I have 3v at power button, but Please answer me this? When i look at the schematic / boardview at the power button connector, they only show 5v_S5 PWR.. I don't see any of the 4 pins labeled as 3v.. So should i be looking for 5v or 3v? (Im not trying to be a wiseass, I'm just...

I get 3/5 ALW...

I'[m working on an HP AIO. board number DAON83MB6G0 rev3. I have the baordview and schematics. The board won't turn on. At the power button, i don't have 5v. The schematics shows bot S0-S5 states and A G3 State.. The only power rails i have with the power adapter hooked up, are those listed...

I have some 32 and 40ga jumper wire i use on phones. I use that.
