I’m using an ASUS PU500CA with Windows 8.1. My laptop was working perfectly but suddenly these annoying errors appear:
+ Windows cannot connect to my Sculpt Touch Mouse. I still see the mouse in the “Devices and Printers” but its status is not connected. I have tried to remove the mouse from the “Devices and Printer” but no use, the mouse is not removed, just the status change to removing device and then nothing happens. Occasionally, this method is useful, the mouse is remove and when I reconnect the mouse, it work perfectly , but if I restart the laptop, all go wrong again.
+ Windows cannot detect any USB device or SD card plugged in. The most weird thing is this happens together with the Bluetooth problem, if I solve the Bluetooth problems by the method above, it can detect the USB devices normally. This happens only with the USB ports and SD card slot, the audio port still works well.
+ The Control panel is often freeze, especially the “Device manager” and the “Devices and Printer”. When I tried to reinstall the bluetooth drivers from the “Device manager” or remove the device from “Devices and Printers”, it often freezes, I can neither cancel the process I have opened nor close the control panel unless I use the Task manager or restart the system. It seems like the system is preventing me from solving the problems. The same thing happens when I use the Troubleshooting Hardwares and Devices, sometime it returns No problems, sometime it runs forever and sometime I can open it.
+ The last problem is I cannot turn off the laptop. When I hit “Shut down” or “Restart”, the shut down screen appears and the dots in the centers circle. After a few minute, the BSOD appears with “Power state failure”. Most time, I have to press the power button some seconds to completely turn the system off.
I have tried everything I found on the Internet but all are useless. I have even reset Windows 8.1 but these errors appear after a few days. I guess it may be because of some recently update or conflict of drivers but I can’t tell exactly which one causes this.
Modern laptops and tablets get smaller and smaller. As a result they provide fewer USB ports for connecting other devices and they rely more on Bluetooth. That’s why Bluetooth mice and keyboards are becoming more popular. But how do you connect them with your Windows 8.1 device? The procedure is not that long but you do need to pay attention so that you perform each step in the correct sequence. Here’s how it works:
Things to Keep in Mind Before Going Ahead
To demonstrate the whole process we have used the the Surface Pro 2 and a Bluetooth mouse from Microsoft that’s named Sculpt Comfort. You can find its review here. TheSurface Pro 2 is reviewed here.
Before you start the whole process, it is best that you start and log in to your Windows 8.1 tablet or laptop and that you have your mouse close, together with its batteries and manual. Also, if you are about to pair your mouse for the very first time with your Windows 8.1 device, you should be connected to a network with Internet access, so that Windows 8.1 can download the appropriate drivers, if needed.
Insert the Batteries, Turn On the Mouse & Make it Discoverable
Any Bluetooth mouse will need batteries before you can use it. Insert them and then look on the back of the mouse. This is where you will generally find the buttons for interacting with the mouse. On the back of the Microsoft Sculpt Comfort mouse we used as an example, there is a switch for turning on the mouse. Press it and the mouse will turn on. Other mice may have a different system for turning them on. Please read their manual to learn how to turn them on.
Turning on the mouse is not enough though. You need to make it discoverable. On some mice, like the one we are using, this means pressing and holding a different button for 3 to 5 seconds. This button has the Bluetooth icon on Microsoft mice. If you are using a mouse from Logitech, the button will be named Connect and it is not a button but a switch that you should turn on.
Some mice have just one button for turning on and making it discoverable through Bluetooth. If that is the case, press and hold the same button so that the mouse becomes discoverable for the next couple of minutes.
On the Microsoft Sculpt Comfort mouse, when the mouse is discoverable, the blue light on its back flashes. Also, if you turn over the mouse, a light blinks green and red for 6 minutes to indicate that the mouse is discoverable.
Your mouse may have a similar system for highlighting that the mouse is discoverable.
