Acer & Bluetooth Generally / How does it work

I have an Acer Aspire 9520 but I am proposing that the exact model does not matter. Just Acer notebooks in general with bluetooth and the little button with a blue LED on the left.

I would like to know how internal bluetooth is set up by ACER?

I understand these bluetooth devices are connected to an internal USB port.

For me installing the drivers (XP, Vista, Ubunutu) is not the only thing you have to do.

At this stage your notebook will show that a device is connected to the USB port but that it is not turned on.

This is the bit that I am really wanting to be confirmed. You need to (with software) give the Bluetooth power. (in fact turn the blue LED on )

For XP/Vista you can install the power management software from Acer which turns bluetooth on. Here as soons as this software loads the blue LED turns on.

For Ubuntu you need to also do a similar thing.

So is this right? Comments?

 

Soooooo as I am a beginner I will attempt to turn that first part into technical speak. And assume that if 45 more people look at it and do not comment that at least i have not written something wrong.

The epower management program is generally called a NHC or Notebook Hardware Controller.

Further making this even a little technicer this is called an ACPI - Advanced Configuration and Power Interface.

Not sure if NHC and ACPI are the same or ACPI is a lower lever more powerful thing????

So in many ACER laptops they require an ACPI command to turn on Bluetooth LED light in oder for the internal USB bus port to recgonise that a device is present and attached to this port. (going back to my speak this would be like turning the electricity switch on, on my 3.5 External hard drive.

 

Hello dardid

Welcome to the Acer Forums. Hope I can help here....

1. Firstly, epower management has nothing to do with Notebook Hardware Control NHC

2. ePower management comes standard on most Acer lappies. Whereas NHC is installed by the owner/user of the lappie.

3. Please uninstall Notebook Hardware Control. I suggest using the lappie for a while first with the Acer software( like I did) so you can understand how everything works.

ePower Management allows you to set things like:

Screen Brightness
Processor speed

etc....

NHC,however, will overide the settings chosen with the ePower Management. There is always a conflict there. Depending on if you understand how all can work together brilliantly.

For the record, I have kept Acer ePower Management on my lappie since day 1 and use NHC in conjunction with it and all runs flawlessly.

Never a Standby situation that does not work(XP)
Never a Hibernate situation that does not work(XP)
Never an issue whatsoever.

My lappie is still very fast.

Kind regards,
Theo

 

Thanks for your reply.

So Epower management does the same thing as NHC. I do not have NHC. My purpose here is to understand how my ACER works with respect to Bluetooth. (which it has )

As far as I can work out to turn bluetooth on this is how it looks.

Battery -->Epower(soft switch) -->Blue LED --> Bluetooth Device --> Internal USB (WOW recognises it has a device attached to it)

Would that be a fair way of looking at it?

If yes what does Epower signal (i assume a controller) that then lets the power flow?

surely somebody knows how acer implemented the turning on of these internal devices. As far as I know the did it on many acers for wireless and bluetooth. I would very much like to know what they signal via their soft switch that turns on bluetooth / wireless.
