Re: Another Dead hp DAR62cmb6a0
I have been doing several power jack replacements a week since 2009 on various models and brands. This includes surface mount and through-hole soldering. I doubt my "technique" is the issue, when the plastic insulator in the center of these jack fail it must be killing something on the board.Comment

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... -

I'm working on a Surface Book 2 performance base (M1032224-004 on white sticker) and would love for some help troubleshooting or where to look next.
The tablet when not connected to the base seems to work fine, but:- When tablet is off and connected to the base, it won't turn on.
- Connecting tablet that is already on to base there is a windows device detected tone (not sure what device), but tablet remains in tablet mode, keyboard/trackpad don't work, and windows continues to report only 1 battery.
- Charger white light turns on when connected to the base, but base battery and tablet

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... -
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)...
