    LA-H331P freezes with power, BSOD with batteryf

    Ok, this is a XPS 15 7590 that it just freezes in seconds when you plug in the power even at bios menu
    With battery only you can get it to work at bios but when you try to boot at OS or try to boot from windows usb boot you get errors like driver overrun, security check failure, page fault in nonpaged area and many others.
    So far ram swapping has been tested and bios update has been performed.
    Could it be an issue at a buck converter that fails with 19V and doesn't work properly with battery either?

    Thank you in advance

    Try changing caps connected with cpu core lines.

      Thank you fro the reply,
      the CPU has 2 main caps at the side at 470uf and one slim at the bottom at 200uf.
      I measured the first two at 500 & 480uf.
      Instead of replacing them as I only have 330uf I made a bridge and added one 330 at the side of each 470uf.
      The test have me the same results, no display with power, BSOD with battery.
      One more thing I forgot to mention is that heatsink becomes too hot to touch - it conducts heat properly and fan spin as they should.

        As you are aware, you cant replace cap with lower value-higher vale will do

          yes, I didn't replaced them but I added 2 more in parallel to maximize the capacitance

            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...

            Canon TS8350 Screen Freezes on Power On
            by joaquinmjuan
            Hello, I have a Canon TS8350 printer. The problem is that when I turn it on, "CANON" appears on the screen, but it never goes away. You can leave it on for a whole day, and it doesn't go away. Does anyone know how to fix this? I've tried unplugging it, but nothing. I've also tried holding down POWER, but nothing. In fact, once it turns on, it can't be turned off with the Power button. I've also held down Power and then plugged it into the Power supply, and the power light flashes once and doesn't turn on, but then when I press Power again, it turns on. Currently, it's a nearly new paperweight,...
