Ultra-Thin

After going through the Troubleshooting process on my Acer Aspire M5-581T, it came back with three errors, see the image below.  What should I do to resolve the issue?

Hello cjb2145,

1-Check in Device manager like this:

- Click on Start

- Type the command mmc devmgmt.msc in the Search box

- Check the device(s) which have a "!". Expand, double click and note the name and version of the bluetooth driver (Atheros or Broadcom) 

2-Download this driver on the Acer support website

3-Uninstall the driver in Device manager (see #1)

4-Install the driver downloaded

Indicate me if you have Win7,8 64 bits.

I have Win 8.1 64 bit.

Hello,

In the Device Manager, you'll find the Bluetooth device. Expand it and follow the instructions I gave you on the reply.

If in origin, you have Win 8.1-64 bits on your ultra-thin then it's this driver:

Bluetooth

Broadcom

Bluetooth Driver (WLAN+Bluetooth driver)

12.0.0.7800

184.3 MB

Download

You'll find the bluetooth user's guide on the Broadcom website.

Thank you for the guidance so far. Although my driver was not broadcom, it was atheros, I followed the same directions and now have the following text when I click in the device status:

Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)

There is still an issue there, just a different one.

Hello,

The problem is than the function "Last Known Good Configuration" is disabled in Windows 8.

So, it's necessary to recover your system. Perhaps it exists a solution with "regedit" or "Microsoft fix it" but I don't kown it.

Problem solved.  It just took a few hours to "marinate" in the sytem, your directions in your first reply fixed the problem.  Thanks for your help.
