    Macbook 1268 No HDD Power

    I Have an early 2011 MB 1268 (820-2915) with a fried SATA cable. Changed he cable and still no response from HDD. Boots with HDD connected to USB without a problem. I am still a bit new to diagnosing logic boards but this is what I have done so far.

    L4500 has 5v.

    J4501
    p1 & 2 = 5 v
    pins 9, 10, 11 & 12 have all close to 5v. the rest fluctuate.

    Also found that It wont turn on with magsafe. Only battery. Once its in MacOS it does indicate that it is charging. Thank you for any help.

      Page 41, some chokes to the sata chip could of bit the dust perhaps.

          I have schematic and boardview. I am new to motherboard repair. I will go over what you suggested. Thanks for the reply, I appreciate it.

              It ended up being a half dead inductor in the SATA circuit. Thank you for your response.

                  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...
                  ORIGINAL POWER SUPPLY BOARD

                  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...

                  Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
                  by sam_sam_sam
                  I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

                  One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...
