    No power compaq parsario cp62 intel

    i am new to electronics this is my first experience fixing dead laptop
    i am dealing with compaq parsari cq62 dead motherboard with power issue.
    My motherboard is daoax3mb6c2 rev:c I have attached the schematic I am using

    this board is completely dead I mean no light no fan running and
    adapter indicator also won’t turn on when I plug the ac adaptor but when I check
    connector(cn16) pin no 7 and 8 both pin have 5volts on page no 25.
    And I get 19volt on pin no 2 and 3 of upper mosfet PQ47 and 27.4 volt on pin no 1(page no 25)
    0 volt on pin no 1 and 2 of lower mosfet PQ51 and 27.4 volt on pin no 3(page no 25)
    But my always on 5volt and 3 volts are there on pl8 and pl4 (page no 26)
    I have checked my power button connector also all pins give the same voltage shown in schematics but
    When I press power button nothing happens I tried shorting the short pad (page no 23) but nothing happens. I don’t know where to check else please someone show me the guide line where to check.

      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...

      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
      by Tynan Dill
      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

      Upon bringing it home and plugging it up, it showed a standby light.

      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

      The screen seems to blackout and stay black, but with a flashlight I can see the display.

      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

      Assuming...

      Microsoft Surface Pro (5th gen) model 1796 - no power
      by PantherDave
      Hi all!

      I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

      I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

      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...

      Power supply Manson NTP-5561 (5661) LCD controller dead - PIC18F87K90 HEX dump required
      by Andreas_de
      Hello!

      i got a damaged Manson NTP-5561 (60V, 1,6A DC output) and and the main issue is that the controler IC for the LCD display has a short. The controler IC PIC18F87K90 is mounted on the back of the back of the LCD. Vss-Vdd = 3 Ohm. The 5V and 3,3V power line was killed as well, but that is not a problem. A new LDO 3,3V and 5V 7805 is already ordered.
      Replacing the PIC18F87K90 is necessary but that makes no sense without having the HEX dump of the new controler.

      Does anybody have such a power supply and could do a HEX dump of the Flash and EEPROM memory?
