Help with identifying problem.

Acer travelmate model# A4DBH doesnt turn on. There is a solid yellow light on the front left side. The first light from the front left(there are 3, but only the one i mentioned is lit up). Not sure what it means.

When i press the power button nothing happen. If i remove the charger and all other connections stays on.

Tried holing down the power button for 30 seconds then reconnecting charger and turning on. Nothing changes.

The solid yellow light remains on.
