The power block's connector to the motherboard is difficult to disconnect by hand initially. While unnecessary, we highly recommend removing the motherboard from the silver casing first to access the power block's connector.

    • Flip the Xbox One S so that the bottom of the case is facing upward.

    • Begin by working at the case on the rear where the warranty sticker is located. Insert the plastic opening tool into the gap between the bottom of the case and the grated top side. Then find the clips in between that hold the case in place. Use the opening tool to pop the clips out. The best method is to pry the black case away from the bottom.

    • Use the opening tool to pop the clips out. The best method is to pry the black case away from the bottom.

    • You will hear clicking sounds when you are prying the case open. It may be fairly difficult to remove the bottom.

    • It's possible that the clips may break when you remove the bottom from the case.

    • We recommend starting at the back where the warranty sticker is located. Pry along the rear edge until all clips are free. From there do each side. When three sides are free start at the end of the front opposite the sync button. Be cautious and take your time and all should separate without any damage.

    • Grab the clamp with the tweezers. Pull the clamp upward, away from the silver casing. Jiggle it back and forth like a tooth if necessary.

    • It's okay to apply a little bit of force here to get the clamp off the silver casing. The metal is bendable and can be bent/clamped back on.

    • you need to unscrew the small circuit board next to the fan before removing the motherboard. I think it is for the Wifi antenna.

    • Remove Mediatek small circuit board labeled D1, D2, and D3

  13. Xbox One S Power Block Replacement: step 15, image 1 of 1
    • Now that the clamp is removed, gently lift the motherboard from its edges out from the metal casing. The motherboard should come out with ease.

So my Xbox One S isn’t turning on at all. No light, nothing. I went to take it apart and I plugged it in just to see if it would boot out of the blue. I turned it on and nothing happened but I can hear a faint clicking sound from the power supply. Does that mean, the power supply has gone bad, and I’ll need to replace it?

Cyology.IO - crwdns2853112:0crwdne2853112:0

yes because this xbox one s internal power supply is a fail.. look at there newer model the “xbox one x “ the internal powersupply of it has air ventilation coming from the upgraded version of the fan.

meaning the xbox one s power supply has no proper ventilation no air that blow the exhaust the heat will stuck up inside .. thats why it will not last longer .

the worst is that its design it self .. imagine when you accidentaly pour a water into the fan .. the water will go directly to the cpu and mobo.

that is why they upgrade the “xbox one x“ they copied the design from the ps4 that the air ventilation is on the side panels..

My xbox one s stopped working after a power surge from a string of storms. It wont respond, make any noise at all. I figured i would replace the power supply and see if that’s the fix. While i’m waiting for the part to arrive, i’m wondering if there is any other damage that could’ve been done by the surge. Or does the power supply prevent that?
