Question about Acer Aspire 4720 Notebook
The most common reasons for power issues are the battery, power adapter/cord and power jack.
If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.
The power jack is inside the laptop and either needs soldering or replacement.
If no change, the power adapter is probably faulty and needs replacement.
Also, power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.
For laptops, remove the heatsink and apply new thermal paste or the motherboard may need replacing.
Leave the power jack fix and heatsink application to an expert.
Hope this helps.
