    Acer H213H power issue

    Very strange problem: monitor works for some days perfectly, then some days it won't power on at all. ( Completely no power).
    I checked the cable, AC 240 input socket. All good. Capacitors look okay. I don't know what could cause this strange problem? thanks for suggestions or places to check...

    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

    Acer Sf314-41 power issue
    by claws77
    my laptop has a weird power-on issue.
    Once the laptop has been powered on, it can restart/ wake just fine on battery power or Adapter, ONLY If i have not closed the LCD.
    If i am running on battery and have closed the LCD (even momentarily). it will not power-on/ wake-up on battery power no matter the battery percentage.

    but once i open the LCD and connect it to the adapter (even momentarily) it will wake up gain and I wont experience any issues till i close the LCD.

    i do not know where to look for repair.
    thank you all for any advice.​

    lenovo flex 5 14itl05 power sequence issue
    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 ....

    Laptop Power Issue – Works on Battery, Fails on Adapter Load
    by yaya3gmax
    Dell laptop (E7440, uses the notorious CD3301B power controller + MEC5075 EC + BQ24715 charger IC)
    Symptoms:
    • Laptop works normally on a pre-charged battery.
    • Battery does not charge when adapter is connected.
    • Without battery:
      • Laptop powers on from DC adapter, passes CPU/RAM init checks, then cuts DC power abruptly.(seems to shutdown one of the mosfets in the charger path). Then the loop continues indefinitely
      • Speakers “pop” when power cut occurs indicating harsh sutdown.
      • If RAM is removed, the system shows RAM missing blink error code indefinitely without cutting DC power
