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... -
Hello everyone,
I have this VGA from a customer. He said that the card worked for ~3 months, it was brand new at that time. In one day were some current intreruption from main powerline and the gpu stopped to work. He put the video card back in box but never send'it to warranty. And after 3 years here it is.
After some measurements - see photo - and both bios reflashed, the video card still not working. The GPU is getting hot very quickly, all voltages are normal, except one coil - L4L5 - which has 0V and strange 10M ohms. Also no visual damages or liquids present. One...07-10-2023, 07:34 AM -
Hello!
This laptop has had a rough time by it's owner (my cousin
), I was told that it was spilled with coke several times, but how it continued to work is a mystery. Last year I was told that the laptop turned off under load and I confirmed the same thing. I had stuff to do and I left it in a corner. Months later I tried turning it on, but nothing was powering on. I took out my multi meter and I found out that the dedicated Nvidia GPU has a short to ground by putting positive multi meter probe on the GPU power coils and negative probe on the ground screw. I removed the GPU power coils,...

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...
