    HP / Asus ptgd1-la bad caps, wont boot with replacements

    I had a typical motherboard issue with an HP yesterday where a few of the filter caps were blown. The PC still booted fine but was obviously very unstable. I have removed the three blown caps and replaced them with the same values. Problem is, with the new caps in, the PC will refuse to power on. The CPU fan moves for a second then the power supply shuts off. Something is going on with that 12v rail. I can remove the caps, and the machine powers on fine again. Plug just 'one' of the three caps in (doesnt matter which) and it refuses to power again. I've attached a pic of what I'm talking about. I've done this literally 100's of times and this is the 1st one I've had do this.

      remember that asus and asrock have the positive side marked on the board, unlike all the other manufacturers which do it the standard way (negative side marked)..

          OMG. I can't believe I didn't think of that. You can even look at the other caps and see that. Thank you! That did it.

              Asus laptop won't boot (no power) - possible bad caps?
              by jrodefeld
              I would like to see if anyone could help me salvage a very expensive laptop that is no longer working.






              The model:               Asus Zenbook Pro Duo UX582L

              I have used this laptop lightly since I purchased it new in 2022. I have always taken precautions to take care of it the best I could, and have never done anything that would risk causing damage to it or shorten it's life.

              However, around six months ago, the laptop stopped working on battery power. It continued to work fine when plugged in, but as soon as power was disconnected,...

              Asus ROG Ally X -RC72LA - changed hidden bios settings with 'Smokeless-UMAF', won't get past boot logo
              by throwaway327
              ASUS ROG Ally X - (Handheld Gaming PC)
              Model No: RC72LA
              Serial No: SBNVKD001014459

              Hi all, I've spent the past week digging through the forums and guides to try correct my foolish mistake of changing hidden settings while tinkering around, and to be honest my heads overloaded so I'm hoping you'll be able to help.

              I used a tool called 'Smokeless-UMAF' to access usually hidden settings in the bios. I tweaked one or two 'safe' things but made the mistake of tweaking a lot of settings under 'USB/Thunderbolt Configurations' when I didn't know what they did. For...

              Asus GL731GT Boot loop
              by trbovan
              Laptop is a GL731GT with the I7-9750h and GTX1650.

              Full model number is gl731gt-rb71-cb
              Serial: (placeholder for when I get home)
              Board model: G531GT REV. 1.5

              Issue: Laptop was password protected with admin password. I extracted the Bios with the CH341A and ASprogrammer. I Initially saved the backup. I then scoured the internet for a rom to flash to the chip. I found a file and flashed it. I then read it back to verify and mistakenly over wrote my backup of the original Bios.

              I assembled and tested anyway. The bios worked, I was able...
