    Hp 255 g5 - dbl51 la-d711p rev 1.0 - does not turn on

    Hello,
    Model: HP 255 G5
    MB: DBL51 LA-D711P REV 1.0
    CPU: AMD 7110
    BIOS: 25Q64FVSIQ

    After connecting the laptop to the charger, the diode at the power socket flashes. 3.3 V available on the power socket.
    The current consumption with the connected power supply between: 0.019-0.022 A. When the button is pressed, the current consumption does not increase.
    I also received information that someone had disassembled the laptop earlier because it had a problem with charging and someone connected other way the main battery to the removed motherboard; /

    Coil voltage:
    PL1 - 19 V
    PL2 - 19 V
    PL3 - 18,68 V
    PL5 - 18,68 V
    PL16 - 18.86 V
    PL803 - 0V
    PL804 - 0V
    PL11 - 0 V
    PL12 - 1.79 V
    PL602 - 0.95V
    PLM2 - 0V
    PL8 - 5.07 V
    PL7 - 3.37V

    Coil resistance:

    PL1 - 492 kOhm
    PL2 - 492 kOhm
    PL3 - 11 Mohm
    PL5 - 11 Mohm
    PL16 - 7,5 Mohm
    PL803 - 204 Ohm
    PL804 - 30 Ohm
    PL11 - 40 kOhm
    PL12 - 5.7 kOhm
    PL602 - 227 Ohm
    PLM2 - 565 Ohm
    PL8 - 18 kOhm
    PL7 - 5.83 kOhm


    Can you still save?Please help!

    by xRaPiDxX
    Hello, the laptop doesn't start, the 2N converter (RT8249CGQW) heats up, it still warms up after the replacement. After flooding, the laptop was cleaned in another service and worked well for six months.Current consumption: 0.170A before pressing the switch, after pressing it without changes. Pins resistance:
    1- 21 kohm
    2- 4,4 kohm
    3- 0,2 mohm - only here 0,8V appears
    4- 8,5kohm
    5- 29,6 kohm
    6- 100 kohm
    7- 66 kohm
    8- 12,7 kohm
    9- 8,8 mohm
    10- 24kohm
    11- 4,6 mohm
    12- 1,7 mohm
    13- 0,5 mohm

    A2289 MacBook Pro - No power - Need help!
    by Dallas90
    Hi everyone,

    I need your help with repairing this Macbook Pro. The fault is that the laptop does not power on. there are different current draw from the various USB ports.
    It is worth mentioning that there is no liquid on the board after a visual inspection. below you can see all readings and info after some diagnostic.

    There are also some thermal images uploaded in the thread.

    What should I do next? any suggestions?

    Thanks in advance.


    Current draw:
    USB port 1: 4.9V - 0.356A
    USB port 2: 4.9V - 0.056-0.60A...

    Dell Inspiron P66F, board LA-D801P, not powering on
    by bub0r
    Hi,

    I have Dell Inspiron P66F with i7 and Radeon graphics with no power issue but with green light on power adapter. I bought it just for repair learning purposes some time ago knowing it is faulty and no more details.
    When I press power button, fan runs for a moment (1 second?) and stops. Similarly LED on button lights up only when button is pressed.

    These are my measurements on board (LA-D801P rev 1.0) with every cable detached...

    Asus Rog G513qr Freezing
    by martin83
    Hello everyone.

    I am here to ask for help identifying a problem with an Asus Rog G513qr, Ryzen 9 5900x and RTX 3070.

    The laptop turns on but turns off or freezes when connecting a USB flash drive (even during the ROG logo). Even without using the USB ports, the laptop is unstable and when the charger is disconnected, it freezes.

    A few months ago, the laptop started freezing when powered only by the battery and in power saving mode.

    After replacing the NVME disk and replacing the liquid metal, thermal grease and thermal putty, it got worse and...
