                  Asus Probook P5440UF-XB74 power issue
                  by GLISIT
                  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!

                  A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

                  Acer Spin 1 SP111-33 Power-On Issue (Troubleshooting Assistance)
                  by justice171
                  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:
                  1. 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.
                  2. Checked the power button functionality:
                    • When pressed, the voltage drops to 0V, indicating the button is functional.
                  3. Inspected the flex cable connecting the USB, audio, and power button to JUB1:
                    • Confirmed connectivity is intact, ruling out issues
                  ...

                  by claws77
                  hi guys, my motherboard will not start no matter what
                  when connected to ac power, the battery does get charge, led indicator glows red when discharged and turns white as it is fully charged.
                  but rest nothing happens no sign of life.

                  this laptop has one preexisting usbc power issue - so i use DCIN jack for charging my laptop.
                  with this issue my laptop was unable to power ON only sometimes i just had to wait some time.
                  but now nothing happens no matter how much i wait/ charge/ press and hold power button.

                  i have no knowledge of motherboards ....

                  Dell G3 17 3779 Weird power cycling and shutdown/restart issue
                  by SuperJames
                  This one's a weird one, and still unsolved despite it having gone back to Dell once.

                  Specs

                  i7-8750H, GTX 1060 Max Q, 500GB SSD & Seagate 7mm 1TB HDD. 17.3 IPS screen. This has the fingerprint reader in the power button.

                  Backstory

                  I bought this from eBay, from a wallpapering shop. £650 in 2020 which was a good price considering it's a gaming laptop. Physically it's in perfect shape, apart from the hinge mounts on the palmrest failing in the time I've had it (I have a new palmrest for it). The usual thin plastic crap modern build quality!...

                  The power supply board reference is the following: DC41-00189a
