I been trying to trace this via for a few hours now, Could someone tell me what Chip gets Ground to power up the console? Or maybe about where it should go? This is from a EDM-033 but i would imagine most are the same.

I don't know that I follow very well, Are you saying you have a short between those two points are are they both shorted to ground?
What is the system doing when you press the power button? Do you get any beeps at all or is there nothing? Have you checked all the voltage rails for shorts and do you have the 5v/3.3v (can't remember which voltage it is off the top of my head) standby voltage on the power button?

Hope someone can give me some suggestions on this because i'm at my wits end with it...
I have an Envy 13-BA1565na here with an Intel Core i7 i7-1165G7 CPU (board is a LA-J475P Rev 1.0) which has an intermittent power button issue. The power button is integrated into the keyboard, and I have ruled out the keyboard, BIOS and battery as being the issue.
Basically, on mains power, the power button works fairly well. The first time you come to it after leving it sitting (either on charge or not on charge), it might take 2 or 3 presses of the button, but then the laptop boots...07-12-2024, 03:03 AM -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hello,
With the power button connected it either boot loops with the apple logo or no display but the charging meter shows it looping on charging every few seconds.
No corrosion any where!
Tried a replacement power button off ebay and the same.
Very occasionally it will work with the power button connected!
Same results with or without the battery.
Can it be a fault with the Audio board or the mainboard?
The touch Id assembly connects through the Audio board first then to the Mainboard.

Hello.
Yesterday my mother encountered a problem with her laptop, which led to it not turning on and expressing the behaviour mentioned in the title (you press the power button and then it turns off after a minute)
Here is what happened:
At one point i was fixing a setting on the laptop to make the laptop properly recognize the NVMe drive i put in months ago. All worked until all of a sudden the computer blue screened. The screen said it would reboot, but it never did. So she held down the power button, powering it off. Pressing it again, the screen briefly turned...10-08-2025, 07:33 AM -
I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...
