                      General question about MacBook power rails for repair.
                      by SarcasticOP
                      I am looking at an A2337 and found this for the order of power rails and what they do. Can this be confirmed before I dive into hunting down power rails that do not exist or are not neccisary?
                      • PPBUS_G3H (12.6V-12.8V)
                        • This is the main power rail that supplies power to the entire system. Check this rail first, as it must be present for other power rails to work.
                      • PP3V42_G3H (3.42V)
                        • This power rail is derived from PPBUS_G3H and is used to power the SMC (System Management Controller) and other essential circuits. It should be present if PPBUS_G3H is working correctly.
                      • PPVRTC_G3H (3.3V)
                        • This

                      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...

                      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.

                      Asus Probook P5440UF-XB74 power issue
                      by GLISIT
                      Hi all,

                      TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


                      I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

                      A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...
