Laptop not charging (Acer Aspite 5810TZ)

My laptop is not charging when plugged in. With the battery powered it works just fine. I purchased a new adapter - the laptop charged as normal but only over night. The next day it stopped charging again.

What could be the problem here? I tested the adapter on another laptop and it works.

A quick search on the Internet will turn up a lot of Acer Aspire One (AOA) owners reporting similar problems. Quite often people update the Bios to fix this problem. However there is similar solution.
The Problem

The Amber (Orange) battery light blinks constantly and netbook works only on AC power.
The Solution

Follow the steps given below. (Please be careful when handling computer electrical components like batteries and AC Adapters)

Remove the battery and hold down the power button for few seconds (to drain all remaining power)
Power up the computer without the battery with the A/C adapter plugged in.
Wait for few seconds and plug the battery back in

After a few tries the computer should start charging normally. The amber battery stops blinking and turn green when fully charge

Thanks for your suggestion. Unfortunately this did not work.

I am not much of an electrician - what could be the cause if there appears to be an electric current running throught the system but the laptop is not charging? I felt a slight charge when I had the system plugged in and my hand touched one of the USB ports.

I've looked at some troubleshooting maps and they are leading me to a possible issue with the motherboard. In my mind that says "must purchase new laptop".

I am open to suggestions.

It is possible the battery itself is malfunctioning,
and in need of replacing. I've replaced the AC adapter and a battery on my
Acer Aspire One ZG5 netbook, but the old battery is still OK and charges,
the adapter had gone bad. Turns out it is a loose connection inside the jack
that plugs into the netbook, so now I have 2. Anyway, I used BatteryEdge,
they have merged with another company, now called Supplies Outlet.

Converter/inverter circuits
Laptops mostly use a small inverter/converter board with required charging voltages or replacement voltage to run the unit when the battery is removed. The little board has the adapter jack soldered to it, sometimes the hack is part of the main/motherboard. Jamming the adapter connector into the jack can break the connector loose creating intermittent operation. With the battery removed, the unit should run on the adapter, if not, the connector is the fault and the most common fault of all laptops.
