    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.

    Texas Instruments TPS51427ARHBT TPS51427ARHBR Dual D-CAP Synchronous Step-Down Controller for Laptop Computers
    by Document Archive
    The TPS51427A TPS51427ARHBT TPS51427ARHBR are dual synchronous step-down controllers designed for laptop and mobile communications applications. This device is part of a low-cost suite of notebook power bus regulators that enables system designs with low external component counts.

    The TPS51427A includes two pulse-width-modulation (PWM) controllers, SMPS1 and SMPS2. The output of SMPS1 can be adjusted from 0.7V to 5.9V, while the output of SMPS2 can be adjusted from 0.5V to 2.5V. This device also features a low-dropout (LDO) regulator that provides a 5-V/3.3-V output, or adjustable...

    MT3608 Step-Up Converter IC Datasheet
    by Document Archive
    The MT3608 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low power applications. The MT3608 switches at 1.2MHz and allows the use of tiny, low cost capacitors and inductors 2mm or less in height.

    Internal soft-start results in small inrush current and extends battery life.

    The MT3608 features automatic shifting to pulse frequency modulation mode at light loads. The MT3608 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The MT3608 is available...

    Recommended replacement cap & voltage
    by aurgathor
    I have an older SFF Dell (GX620) that I want to turn into a router, but it has a few *really bad* looking electrolytic caps (4x 2200uF 6.3V & 1x 1800uF 6.3V) that need to be replaced first.

    Questions:
    1. What are some the recommended caps for these values? (I will probably order from digikey)
    2. Looks to me there is enough space for slightly bigger caps -- would I gain anything with respect to longevity by using 10V caps instead of 6.3V caps? (I guess I probably need to look at the current voltage with a scope since I do not know the nominal voltage of that r...
