    [HELP] HP 255 G8 - "INCREDIBLE PROBLEM"

    hi to all, i have an hp 255 g8, motherboard HPL51 LA-L021P with a super strange problem. I HAVE ALREADY TRIED WITH ANOTHE POWER SUPPLY AND A BRAND NEW DC CONNECTOR

    WITHOUT BATTERY

    if i connect the power cable of original power supply or a power cable from my power bench i can have

    white led steady, and i can boot the system
    white led only for some second
    nothing

    WITH THE BATTERY

    i have ALWAYS RED LED (charging)

    some times it start to charge for like 2 minuts then it simply stop
    sometimes it doesn't charge at all (even with red light)

    the notebook can boot, but after some minutes power it off itself..

    i don't know where to start...

    no official schematics or board view

    but i have found this

    https://www.badcaps.net/forum/troubl...-and-boardview

    and the motherboard seems the same

      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...

      Asus Z97-a power cycle, no boot no cpu voltage
      by meraklinetx
      Hello, I have an asus Z97-A motherboard and it doesn't start which was working properly before, the problem isn't related by ram, ram slots or psu (I changed all and nothing work), the exact problem is when you switch it on , it starts and after 1 seconds (no boot or display picture) it's off and then on cycle continuously until you power it off from psu also it's responding to the power switch for turning it off if you keep pressing it 3 or 4 seconds (power button pin has 3.3v) , also when you start it with eatx 12v socket connected this is happening (power cycle also all voltages are resetting...

      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.

      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...

      Bang & Olufsen (HP) Omen Laptop power light flashes once but no boot
      by dicky96
      Hi guys
      I have a B&O Omen laptop here. It has very specific fault symptoms, hopefully someone can give me some guidance

      If I plug in a known good 180W third party charger the little LED next to the power jack on the laptop flashes red once, but the laptop will not start. It will not flash red again unless you unplug and reconnect the power.

      If I remove the main battery (I can't see a cmos battery) then the led by the jack does not flash when I plug in the adapter, but if I press the power on button with adapter attached it flashes once white every time...
