Manual. I suspect that the information you have been given regarding battery removal and passwords refers to removing the cmos battery as in a PC in the hope that it will clear Bios activated passwords.
It sounds like it could be either the battery is going bad and not holding a charge or the adapter is. I have had really good luck with similar problems going to places like Batteries +, and large electronic retailers, and my favorite the small local mom and pop computer store; where I end up asking them If I could try one of the adapters from the floor model to eliminate if is a faulty adapter.

The Acer Aspire is a high-performance laptop that includes a fast processor, widescreen display and an internal wireless card. In addition to these premium features, certain models also include one-touch Bluetooth access. If you have an Acer, enabling the Bluetooth is very easy and will only take a few seconds.
1.Turn on your computer and wait for Windows to fully boot. Then log in as an administrator. You will not be able to use Bluetooth under a non-administrator account.
2.Press the button with the Bluetooth symbol on the left side of the computer. This will launch the Bluetooth utility. From here you can sync and manage Bluetooth peripherals.
3.Press the Bluetooth button again to disable Bluetooth. This will disable all connections, but the utility will save your settings so the same devices will sync with the computer again when Bluetooth is re-enabled.
According to the manual, "Located beside the keyboard are application buttons. These buttons are called easy-launch buttons. They are: WLAN, Internet, email, Bluetooth, Arcade and Acer Empowering Technology." Pressing the Bluetooth button should toggle Bluetooth on or off, assuming the correct drivers are installed.

For Acep Aspire 504x model systems that have Bluetooth built in, there is an on/off switch located in the front of the system.
For systems with bluetooth built in there will be two buttons next to each other just left of the mic and headphone ports.
The left of the 2 buttons is the bluetooth switch and the right of the 2 buttons is for 802.11 wireless.
If you only have 1 button then you do not have bluetooth built-in. You can also check to see if bluetooth is included by looking at the bottom, if Bluetooth is installed there will be a white FCC lebel with the name Bluetooth written on it.
