    HP 14-ac103nt power on problem

    HI all,
    I have this laptop without original charger. It has small connector with middle pin - charger detect pin. I try this laptop with laboratory power supply, led on power connector is ON but laptop won't start. When I plug the battery charge led is red but power consumption is low - no charge the battery. I mean my problem is I don't have connected middle pin. Before I buy original charger I want to try if laptop is working or not. Is the way to connecto some resistor from middle pin to +? which value? can someone help me with this? thanks.

          because I don't have charger for this model. I want to try it first if it is possible, before I buy charger.

              430k will be good

                  Middle pin - 19v 430k and still same. Maybe laptop have some other issues.

                  0.575v on middle pin

                  mobo is 6050a2730801-mb-a01

                  have someone schematic, boardview for this motherboard?

                              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)...

                              Hi,

                              Try to repair a Thinkpad P72 EP720 NM-B723 MB with I7-8850H processor and N18E-Q1-KB-A1 (P3200) GPU with 6GB memory. Unfortunately there is noinfo what happened to the laptop. I got it disassembled with parts missing, like keyboard, battery.

                              Unfortunately I have no schematic available for me (requested in the sub porum) but got the boardview file.

                              Symptom: after connecting to the charger the power led light up for one-two second and switch off. After a couple secons the power led light up for half a second and switch off. No battery, no IO board, no...

                              Hello, trying to fix C9 55 inch. I have pulled the back and all looks completely normal with nothing burnt so far. This is first time attempting to fix a tv so any help is appreciated.

                              Problem. I hit power button, red light on TV turns off and tries to turn on, no picture shows up and then shuts off. This occurred after house power turned on and off, not from a storm.

                              I have tested the power going from power supply to main board, all 12v and 20 volt readings are proper when I hit power button.

                              The power supply to t con is different story.
                              This...

                              by Dr.d
                              I have a lenovo ideapad 5 14itl05, board LA-K321P, That will only power up on Battery only, or with battery disconnected and power adapter only. If battery is connected and usb-c power plug connected. It only works on battery and will not charge. I can however force it to charge by connecting the battery from a disconnected state while the power USB c plug is powering the laptop.

                              Additionally....to add to this strange situation. The usb-c power plug ONLY works to power the laptop on one side when inserted into the boards power usb c plug. If you rotate it 180 degrees, the board gets...

                              Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
                              by sam_sam_sam
                              I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

                              One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...
