Hi
With adapter plugged in to you have your voltages: like alwon 3/5V after power button press core voltage there. If you plug a external keyboard or mouse in does it light up or if press cap lock does it light up . If not you are missing secondary voltage start with flashing bios.

Hi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!
I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

Hi all,
My Samsung TV display recently stopped working while I was playing PS4 (no storm or anything to indicate a power surge). I could still hear audio through the PS4 but no display. The TV kept trying to turn on but would turn off after a second or two.
I tried the obvious troubleshooting steps like unplugging, replugging, trying different outlets and power cords with no luck. Someone on another forum suggested that it may be a power supply issue so I purchased a replacement power supply board but that did not help. I then disconnected the main board from the...08-31-2021, 09:32 AM -
I have a vintage 2008 Samsung 50” Plasma TV, Model code PN50A550S1FXZA with a power supply part number BN44-00222A. I repaired the power supply board several years ago finding a couple of cold solder joints on the back side of the board and it's worked great up until now. Recently a fried sound occurred with the smell of burnt electronics and the TV shut down. Trying to turn it back on yielded the typical relay clicking with no TV boot up.

I am seeking guidance on an Acer Spin 1 SP111-33 that does not turn on when pressing the power button.
Below are the observations and troubleshooting steps I have taken so far: Observations and Tests:- Verified that all critical voltages are present:
- 3.3V and 5V are always present if DC is plugged.
- 1.8V on the BIOS chip is present.
- Checked the power button functionality:
- When pressed, the voltage drops to 0V, indicating the button is functional.
- Inspected the flex cable connecting the USB, audio, and power button to JUB1:
- Confirmed connectivity is intact, ruling out issues
