    ACER E5-411 Power Issue

    Hello!, Anyone could please help me fix the issue of Acer E5-411

    I have an issue with an Acer E5-411.
    It´s not powering. I have 3v on power switch, but the power is not going to the RAM slot. Voltage on Bios is OK.

    I traced a little and I found that if I inject 1v on PR63 the consumption goes off the roof and it cuts the power supply. And Nothing gets hot...

    I'm really new to this, and I appreciatte any ideas.

    Have a nice day!

      This is PR63, and everything on 1v does the same.
      Maybe the Processor is the issue?

          If inject 1V on the Magenta marked side, eveything is OK
          But if I inject 1V on the Red marked ones the consumption goes up

              Why you are playing with voltage injection without proper diagnosis?? You may simply kill the soc. Since you dont have voltage on ram, why not probe the ram ic first. Just do basic things to start with.
              01.Check resistance on all big grey coils
              02.Check resistance on bios pin8
              03.Check ram ic pins for voltage.

                  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.​

                  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 ....

                  Hi all

                  There's two other threads about this monitor with seemingly the same problem. The problem was resolved in one case by replacing the entire PSU board and in the second one by replacing an unknown IC.

                  The first one has pictures of the pcbs and I noticed that there's one IC and assorted caps not populated on mine (but the PCB itself looks identical) so I thought that'd warrant a new thread.

                  It's my dad's old monitor. He...
