Boards may also include date codes (e.g., "0716" for 16th week of 2007, or "0926" for 26th week of 2009) printed on the board.

Remove the shorted component (use tweezers while hot air is applied at 380°C). Recheck resistance – it should now be in kilo-ohms. Replace the 0-ohm jumper. The board is now SAFE to plug into a real 19V adapter.

Laptops with HannStar J MV-4 boards often face standard aging issues:

Large capacitors near the CPU/GPU, which can short. How to Fix the Overheating Component

This is the name of HannStar Display Corporation , a massive Taiwanese contract manufacturer. While famous for LCD panels, they also operate a massive Printed Circuit Board (PCB) fabrication division. They manufacture the raw, bare fiberglass circuit boards for third-party design firms.

Technicians seeking this boardview are often dealing with several "hot" or frequent failure points associated with these boards:
