Symptom or Problem Encountered
Machine powers down unexpectedly and/or is generally unstable. Out of spec values for voltage rails are shown In the PC Health Status screen of the BIOS.
- Failing capacitors on the power supply board and/or a failing power brick
- Replace capacitors on the power supply board. May also need to replace the power brick.
This device came with a 19 V 4.74 A power brick. Barrel plug is 5.5 mm OD x 2.1 mm ID, and is center (tip) positive.
Power Supply Board
Power supply board is labeled "Migrus C5" and is located in the front left corner of the case.

Any 5.5/2.1mm center (tip) positive power brick rated at 19 V and at least 4.74 A should work. The author of this page is using this Nobsound power adapter and it is working well.
Power Supply Board
There is a fair bit of wiggle room on and above the board, so you can fudge a little on the cap dimensions. In particular, the cap they used for EC12 was a very short "low profile" one which is hard to find, and was easily replaced with another (more "normal" sized) capacitor of the same values.
