    You mean 5V & 3V appear when you insert charger in dc jack but goes away after 5 seconds?? Right??

    If so, thats perfectly ok as allmost all newer mb has 3V/5V rail as "Suspend". 3V LDO should be present all the time and i think its present as dc jack light keeps glowing. So nothing wrong here.

            You can refer to HP Quanta Y11 diagram for IT8987E pinout. Have you flashed known good bios with clean me?? If not, request for same in "Bios Section" while posting your old dump.

            If it doesnt help, then we'll proceed to measurement on KBC8987E for its basic requirement. But first flash bios.

              Lenovo Thinkpad P72 EP720 NM-B723 MB - Power disabled within 2 seconds after plugging the charger
              by Mita99
              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...

              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...

              Lenovo 15iml05 Power led lights for 12 seconds then off 12 seconds
              by liquidzorch
              Hello. I bought a faulty Lenovo ideapad 3, but it turns out the 3Valw buck converter burnt a hole through the board. I was able to clean it up, and remove all the shorts. I now can power the 3.3v rails from a bench power suppy while connecting the laptop to its psu, and I get the additional 5valw, 1.8v, and 1.05v, form what I can tell in the schematics, those are the only 4 voltages I should see before turning on, and they are present. When I hit the power button, the power indicator on the left side turns on (not the one on the power button), stays on for about 12 seconds, then turns off for...

              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...
