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
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.
