Known Issues

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.

Causes

• Failing capacitors on the power supply board and/or a failing power brick

Solutions

• Replace capacitors on the power supply board. May also need to replace the power brick.

Original Parts

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

Closeup view of the PSU board

Power supply board is labeled "Migrus C5" and is located in the front left corner of the case.

Replacement Parts

Power brick

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 I was unable to find; however I was able to fit a "normal" sized 100 µF cap from my parts bin with no trouble.
