laptop not recognizing device when plugged into laptop how to fix


The computer is not recognizing the device because the appropriate software or driver is not installed on the device.

Most of the time when you connect a smartphone into a compatible laptop the device drivers or software automatically install, so the laptop may recognize the smartphone.

Here are some possibilities as to why the device is not recognized.

1) The USB port is bad.
2) The USB port is not activated
3) One of the devices does not support the other

Here are a few possible troubleshooting solutions:

1) Go to the smartphone manufactures website and download and install the updated device driver and software then plug in the device to see if it is recognized.
2) (if Windows OS) Go to the Device Manager to see if the device is showing up when it's plugged in. If you see the device in device manager right click the device and choose to update the driver.
3) (if Windows OS) Additionally, in device manager you can check your device's USB ports to see if there is an issue with the ports that may be resulting in the smartphone not being recognized. You can choose to re-enable the USB ports or update the software for the USB ports.

Hopes that helps resolve your issues.

Restart your computer. After your computer is rebooted, connect your camera to your computer using the USB cable provided. Note: Connect your camera to an alternate USB port, preferably on the back of your computer. Select MTP instead of default PC from the USB select screen appears on the LCD screen after connect the Camera to the Computer. If the issue persists, please check the Device Manager driver conflicts by following the steps: Connect the camera to the computer with the USB cable. Turn on the camera. Open the Device Manager of the operating system.

I hope following the above troubleshooting steps should definitely resolve the issue. If you require any further assistance, please get back to me with the exact Operating System, I can definitely help you with this.
