Fix: Currently, This Hardware Device is not Connected to the Computer (Code 45)

Described below is the error message a computer running on the Windows Operating System spits out when it fails to recognize a hardware device connected to it. In most cases, this error message is seen when a hardware device that was previously connected to a Windows computer is disconnected and then connected to it again, at which point the system, for some reason, does not recognize the device anymore. This error can also be seen in the General tab of the Properties of the affected hardware device’s listing in Device Manager.

Currently, this hardware device is not connected to the computer (Code 45)

If this error message shows up for a hardware device, that specific hardware device doesn’t work even if it is connected to the affected computer. This can certainly be quite the annoyance. Thankfully, though, the following are some of the most effective solutions that users affected by this problem can use to try and resolve it:

Solution 1: Make sure the physical connection between the device and computer is secure

First and foremost, you need to make sure the physical connection between the affected hardware device and the affected computer is completely secure. The connection needs to be secure and properly seated on both ends, and if ensuring that’s the case is not enough to get rid of this problem, you should move on to trying and fixing it on the software side of things.

Solution 2: Run an SFC scan

The System File Checker utility is a built-in Windows utility designed to scan computers running on the Windows Operating System for corrupted or otherwise damaged system files.

CHKDSK is a Windows utility capable of checking for and repairing hard disk corruption. If damage inflicted on your computer’s hard drive is what is causing this problem for you, running CHKDSK on your hard drive might just be enough to get the job done. To run CHKDSK on your hard drive, you need to:

  1. Open the Start Menu.

  4. Type the following into the elevated Command Prompt and press Enter:

  1. The elevated Command Prompt might inform you that CHKDSK can only be ran upon a reboot and ask you if you’d like to do that. If it does so, simply type y into the elevated Command Prompt and press Enter to confirm the action, close the elevated Command Prompt and restart the computer.

Solution 7: Check to see if the hardware device is faulty or dead

If absolutely none of the wide array of solutions listed and described above have managed to get rid of this error message for you, the problem might just lie with the affected hardware device itself. If the hardware device in question has become faulty or has died altogether, Windows won’t be able to interface with it, and will instead spit out an error message such as this one. In addition, if the hardware device itself is no longer of any use, noting you do on the software side of things will provide any relief. The recommended course of action in this case is to get the hardware device in question checked to see if it really is faulty or dead, and if it turns out that it is, get a replacement for it. Getting a replacement for the affected hardware device should absolutely resolve this problem for you.
