    Gateway MT6451 dead

    Have this laptop, is totally dead, no light nothing, don't have much knowledge on these, I have found a shorted capacitor: PL18 traces over to PQ28 and PQ26, wondering if the cap is bad or the PQ28 is making it show short, not sure how to test PQ28. Will try to find info on testing PQ28, thanks for any thoughts.

      C712 is not beeping on one side/no continuity like most of the caps, testing in diode mode with negative lead to ground.

        PL18 is an inductor.
        Post high resolution pictures of both sides of the board.

          Sorry can't only have a lousy phone camera at the moment, resolution is crap.

            Going to try replacing C712 and see if I get continuity per the cap test, it isn't reading short when I put a probe on each side but the continuity on one side when using ground reference is not there meaning no beep/buzz on either side.

              How can I be sure that my EC chip is dead?
              by double_DD
              Hi all,

              As the title suggests, how can I be sure that my EC chip is really dead?

              I've recently gotten into this hobby of laptop repairs, and have successfully brought back to life a couple with some easy fixes, mostly shorted caps.

              Now I'm working on HP Probook 455 G8, that had some "devil" run around on 3V line, burning a bunch of stuff. Luckily I have a dead 455G7 (for spare parts) so I managed to fix it (swapped burned parts) to a point that it will charge (both on barrel jack and usb-c), but it doesn't want to turn on. There is a 3V3 on a keyboard...

              ps5 edm-033 dead after hdmi/usb ports destroyed
              by disorder
              hello guys,

              i need help to repair a edm-033 ps2
              history : as always hdmi port and usb ports destroyed after unplugged
              after change them, ps5 dead too : 1 beep, no blue light. after inspection 1.8v power was shorted, and because of dead panasonic chip. after remove it : no short anymore
              so i changed it
              now i have got 5v stby,, 3.3v stby, 3.3v power, 1.8v power and no short on them
              but the ps5 is dead again : 1 beep, near 10 seconds with power lines and then off, no blue light ...

              i don't see any projection of liquid metal on pcb.
              ...

              Finding a dead short component
              by Beton
              Hi guys!
              I searched for the term "dead short" in the forum but no specific thread came up however if I'm just blind and couldn't see the thread talking about this please forward me to that direction.
              So my problem is I don't know how to find the source of a dead shorted voltage rail. Dead short = ~0 ohm resistance.
              I have two VGAs (HD 4850 and HD 4870), both dead shorted to ground on the memory rail. I have the boardview file for the 4870 and the memory rail consists around ~7892346 capacitors...
              I have a bench PSU and if I try to inject voltage the voltage...

              Chieftec GPS-450-AA with dead 20N60C3
              by zunasthegreat
              Hello everyone hope all doing well!
              I have this PSU (GPS450-AA delta oem) around for like 4-5 years and I had it recapped early 2020 or 2021 with mostly UCC KY and Nichicon PW's. The bulk was and still is fine, the original Ltec's were bloated and empty. The previous issue was some major coil whine noise and at times random shutdowns when going idle. Today it started tripping the mains breaker and I think I have dead APFC mosfets (20N60C3). Right now upon checking I have the Q1 and Q3 FETs dead so far and I guess those are responsible for the PFC circuit. The only thing I care is If there...

              MSI Raider GE75 - Not posting, probable dead CPU
              by FiguringITout
              Hello, today I'm working on this lovely MSI Raider GE75 gaming laptop which I bought to flip. Unfortunately, I believe the CPU is toast but I wanted a second opinion before I chucked it into my spare parts bin. I will not have most tools with me today as I'm away from my workbench but I have the basics (a good multimeter, a horrible iron, a solid screwdriver, and my trusty thermal cam). I do not have the original 230w charger, but I have a Dell 180w which was sold with the device and reportedly "worked fine for them".

              Specs: I7-10750H, RTX 2060, 32GB RAM (unknown manufacturer)...
