      Check RTC circuit completely.

          thank you for your response.
          i checked it i didnt find any problem.
          ichecked the charging circuit
          internal battery rating is 14.8v and when i connect the battery it has around 16.5v and when i connect the charger i have around 17v on battery pin
          last night i charged the battery fully and left it for the night today i came back it wouldnt turn on with battery only. when i connect the charger device turned on.

              Remove the battery.

              Does the unit turn on every time with only the original power adapter ?

                  no i test that too, at some point it wouldnt turn on at all with or without battery
                  i reprogrammed the bios then it turned on after awhile same thing happend but with changing bios ic and program didnt power on anymore.
                  i think the pch maybe be the problem

                      Hi everyone,

                      I'm working on an Acer Nitro 5 unit with the following specs:
                      • Motherboard: LA-J871P Rev: 1B
                      • Model: Acer AN515-55-59MT
                      • S/N: NHQ7JAL00403906A973400
                      • SNID: 03902728734
                      Initial Issue


                      The laptop initially presented graphic issues and driver failure (Code 43) for the GPU.

                      After preventive maintenance (cleaning, thermal paste, etc.), it powered on normally. We disassembled it again to inspect the GPU, reassembled...

                      Problem with LG Plasma 60PM6700 - Random power downs
                      by theone111
                      I have an LG Plasma TV 60PM6700 for the past ~12 years.

                      In the last ~3-4 months I have been having some issues.
                      1. Problem: It started with random picture disappearing (sound still worked).
                        Frequency: Happened about once a week.
                        Solution: Had to turn off TV wait a few seconds before turning it on again.
                      2. Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
                        Frequency: Happened about once a week.
                        Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve.
                      3. Problem: TV shuts down

                      by Duranitron
                      When I reflash again the bios of hoaca388 the unit powers on and the unit lives!!! Hooray!! All voltage in the coil 3.3v, 5v and 6.7v indicate charging are all present. including the cpu voltage , EEPROM and GPU voltage the unit is now alive, normal screen booting to windows and log in screen until I power it off. Then the unit never goes on even when pressing the power button in the keyboard.. Voltage reading 19v main , 3.3v VCC in IT8225E-128 and EEPROM VCC 0 volt and the charging voltage 0 volt.

                      Try to trace the power switch button goin to the power switch IC PU8803 (APL3533AQBI-TRG)...

                      ACER ASPIRE A515-52G CAN ON BUT NO DISPLAY, NO POWER AT VCC_GT
                      by Bonaventure Vigil
                      Dear All,
                      Please really2 need Help on this Acer A515-52G Motherboard Compal EH5AW LA-G521P Rev: 1A.
                      At first this laptop can on, keyboard light on but no display. Open the motherboard, found out the PQZ3 Mosfet and PUZ3 ic near it burn. Refer picture below. Then I replaced both. All the power rail 3.3,5,1.2, 1.35, 0.8V have power back after i turn on the laptop except for the VCC_GT rail. Voltage at Power Supply showing 0.000A before turn on, after turn on it became 0.5 0.6A. Seem cannot boot and still no display. Then I replaced the PUG1 and mosfet, but the VCC_GT still no power....

                      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
                      ...
