How to repair USB-port
Checking mechanical damages
Before proceeding to more complicated techniques, we recommend paying attention to the physical condition of the port. Plug in the USB cable and move it gently in the connector to see how loose it is. If you do not know the standard socket packing ratio, check first in the working socket.
A fairly high freedom of movement inside the port indicates that it is loose and needs to be replaced.
The main thing to remember, do not make any sudden and strong movements, because there is a great risk of damaging a healthy port, and not finding the real cause of failure.
Reboot your computer
In rare cases the operating system may simply not notice the new installed hardware. Therefore, to fix this error, restart your computer. Windows will rescan the list of plugged devices and display the flash drive or external hard drive you need.
This section applies specifically to the hardware and its software. Very often the devices are not able to function properly because there is a driver failure or the controller has stopped working correctly. We have prepared for you two methods inside the utility Device Manager, which will help you to quickly restore the USB port to a working state.
Open the Device Manager. To do this, do the following: Right-click on the My Computer icon Computer Management Device Manager.
An alternative way, and maybe for some more convenient, is to open the Run Utility, and in the dialog box that comes up, type devmgmt.Click msc and press Enter.
Open the USB Controllers section. There should be two controllers named Intel(R) 7 Series/C216 Chipset Family USB Enhanced Host Controller. Depending on the manufacturer the names may be different, but the USB Host Controller part must be identical.
Now click on the Update Hardware Configuration icon.
Restart your computer.
An alternative way is to remove these two controllers before the next restart. This will allow the Windows operating system to make the necessary adjustments on its own before launching.
USB Suspend setting
The option to temporarily disable the USB port is a Windows tool that allows the computer to increase battery life. This is especially important for laptops. This is how the operating system temporarily shuts down power to a USB port that has been idle for some time. To restore stable port operation, follow one of the following two instructions:
Method 1. Power Options.
Open Windows Settings with a Win I key combination.
Go to System.
Navigate to Power and Sleep.
Scroll down to the bottom of the page and under Related Options open Advanced Power Options.
Choose the power profile you desire and go to Power Profile Preferences.
Go to Change Advanced Power Options.
Look in the USB Options section and expand it.
Now open the subsection USB Port Temporary Disable Parameter.
Change the values in Off Battery and On Line to Disable.
Click Apply and OK to confirm your changes.
Method two. Registry Editor.
When working with the registry, it is important to remember that the health of your operating system depends on its health. You should never, under any circumstances, make unreasonable changes to it. Therefore it is strongly recommended to make a backup copy of the registry before trying this method.
Open the Run Utility by pressing Win R.
Type regedit in the following dialog box and press Enter.
Go to the following path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USB\DisableSelectiveSuspend. If you do not have one, you will have to create it manually.
Create a new DWORD Parameter (32 bits).
Give the parameter the name DisableSelectiveSuspend.
Right-click on the key and click Change.
Set the Value to 1 and press OK.
Done. Check if your USB port is working.
To replace damaged hardware
If none of the above methods can help you, the chances are that your USB port is damaged beyond repair. The only thing that can change the position of the connector in the nearest service center.
We hope you found this article useful and that it helps to bring your USB port back into working order.
Installing the new USB port
Before you replace the port, it is worth finding out its type 1.0, 2.0. The equipment you will need is a soldering iron. The board is fused by the rosin.
Once the laptop is disassembled, it is worth locating the port. It is on the board and must protrude. It’s hard to mix it up with other connectors. In a pinch you can attach the USB cable. It is not always possible to just pull out the motherboard.
Since this is a laptop, you will see that all the modules are closely spaced. The board can be jammed with a hard drive. To solve the problem disconnect the drive and then the chipset. The hard disc in most models is fixed with four screws. Very rarely there are exceptions when protective plates are used. Hidden screws make the job more difficult. Behind the sticker there may be an extra catch, without which it is not possible to disconnect the element. The secret is to get to the board.
The list of surprises does not end here. When unfolding the port you should pay attention to its shrinkage. If thermostable solder is used, you can not do anything with a standard soldering iron.
SEE FOR MORE INFORMATION! When the surface is heated, the contacts remain in place.
During the selection of equipment is worth paying attention to its power. The more expensive laptops exactly use the heat-resistant solder. Such connections are considered to be long-lasting.
The second step is to select the USB port. If you go to a radio store, there are several options:
The difference lies in the quality of the contacts. Additionally different side brackets are used, pay attention to their shape. Even if you have purchased port 2.0 as installed on the native notebook, in place it turns out that the landing slot is somewhat wider or narrower.
When the workpiece is wider, you have to rework the laptop socket. With the help of a file is possible to expand the output. The second option is to move the tendrils on the module. Requires jewelry accuracy, so it is better to take a magnifying glass and tweezers.
During installation, it is worth adhering to the rules:
When novices are engaged in soldering, the USB module is shifted to the side or protrudes backwards. Either way, it is difficult to install the notebook lid. The vertebra tester can be used as an ordinary tester. If the contact is not broken, the circuit will show “closed”.
When the port does not fit into the laptop body, you have to modify it. Specialists recommend using wire cutters for this purpose. A file option will also do the trick. Everything depends on the shape of the cover and its height.
In many cases the USB port does not need to be completely replaced. When a person unscrews the case, they see that one of the pins has come loose. So it makes sense to solder it to make the system work. Professionals always find that the universal serial bus does not work correctly. It happens for several reasons:
To fix the case, a tool is prepared:
If a contact has come loose, it is much easier to work from the edge. When this happens in the middle it is impossible to get to the right place. You have to completely replace the part or solder the adjacent contact. The electronic circuitry looks extremely simple, since there are only four leads. The service center will definitely not save the old module, and there are good reasons for this:
If there is no desire to save the old port, even if the contact has come off the edge, you can prepare a new USB module.
When disassembling the laptop may turn out to be defective not only on the USB, but also on the motherboard.
These are the parts of the motherboard otherwise known as the controllers. The north bridge is responsible for the connection to the processor. The USB port can fail because of the South Bridge. In addition to connectors, it is responsible for communication with the audio board, bus, keyboard, mouse.
If you look at a motherboard diagram, the coveted south bridge is located near the processor. It looks like a black tablet with a small inscription. Check the controller is easy even without special equipment.
DESCRIPTION! If the connection is broken, the element heats up to the limit.
If the laptop is on, it is worth touching the place with your finger and understand its condition. When the bridge is hot and strong, it means that it is definitely living its last days. Have the controller replaced by a service center.
What to do if the USB on the front of the PC does not work
Another common situation. all the connectors work properly, but the connection to the USB on the front of the computer does not lead to anything. Almost always the reason is that these connectors are not wired to the “inner” USB connector (pictured below) on your motherboard.
About this in detail and with photos in the second part of the instruction How to connect the computer front panel connectors to the motherboard.
USB ports in your computer or laptop do not work
USB ports are the most popular ports. If HDMI, Ethernet, 3.5 mm, DVI, VGA and other cables are rarely taken out of their respective ports, many users poke various cables and devices into USB ports several times a day. Although the port is made with durability in mind, there comes a time when users are faced with the harsh reality of a broken USB. If a USB port in your computer isn’t working, the cause isn’t necessarily hiding in a hardwire failure. Fortunately, this problem can often be fixed software, which means you do not have to carry your computer to the service center. In this article, we’ve put together some tips that you can use to try to resuscitate a suddenly failed USB port.
FYI: We do not guarantee that these methods will help you. Some part of this instruction will help, and some will not. If the USB port is physically broken, no amount of software tweaks or reinstallations will bring it back to life. In that case you need to go to a service center and change the broken port.
When the USB ports fail, your connected peripherals may stop working. Your mouse or keyboard, for example. In that case, you may need a manual that tells you how to control the mouse with the keyboard.
USB ports don’t work, what to do?
One of the rather popular problems on PCs and laptops is the sudden disconnection of USB ports (t.е. It seems like a couple of days ago everything was OK. and now the computer just does not see the connected device).
By the way, in addition to the simple invisibility, errors like: “USB device not recognized”, “Unknown device connected to USB”, etc.д.
And without USB (not for me to tell you). neither here, nor there, because this interface is one of the most popular today, almost all the peripheral equipment (keyboard, scanner, printer, etc.д.) is connected to it.
In this post I have given you several recommendations which in most cases will help you to solve this problem (of course in those cases when the hardware of the device is in order). If the controller fails or there is a mech. damage. then here except a workshop (with a soldering iron) and replacement of the damaged part no one will help you.
The first steps in troubleshooting
If you see a message on the screen that the USB ports stop working or the laptop does not react to the installed in the corresponding slot, this may indicate a problem with the drivers.
Sometimes you can solve them by simply rebooting. there is a small chance that the fix will happen automatically.
The chance of solving the problem in this uncomplicated way increases even more if the laptop is connected to the Internet.
Increase the likelihood of a positive effect of rebooting, which, indeed, sometimes helps, can be done in a not quite normal way:
1Remove the laptop from the mains (if it was for example on the charger);
How to Fix USB Ports Not Working in Windows 10/11
2Remove the battery and leave the laptop in this state for about 5 minutes;
3Insert the battery back and turn the device on.
If there are no messages on the screen about the ports not working, but the flash drive is still not readable or there is no connection of a peripheral device to the laptop, it is possible that the problem is in this equipment.
Check your assumption by connecting the gadgets to other ports on your laptop. or to another computer.
Checking the status of the ports
If you insert a USB flash drive and receive a denial of access, you can blame both the mobile drive and the means of communication. So the first thing to do is to check if the port is not clogged. This is considered the most common cause of failure, because the design of the slot is open, which contributes to its rapid clogging. If the front panel is sometimes protected by a flip-open cover, the back or laptop ports are not protected in any way.
So if the USB ports stop working and you suspect that it is because they are clogged, take a moderately soft brush with long bristles and perform the hygienic procedure. If after that the USB ports on your PC / laptop does not work, it is likely that the reason lies in their physical damage. If a USB stick doesn’t stick or doesn’t stick all the way into the port. most likely the port is broken. Only replacing it will help.
Probably the reason of non-operability of the device, connected to the PC, is a damaged cable. try to replace it and try to connect it again. After all, the device itself may be not working, and this is also easy to check by connecting it to a known faulty port or to another computer.
What to do if the USB connectors on the front panel of the PC don’t work
Another common situation is that all the connectors work properly, but connecting to the USB on the front of the computer does not lead to anything. Almost always the reason is that these connectors are not connected by cable to the “internal” USB connector (shown below) on the motherboard.
Read more about it with pictures in the second part of the instruction How to connect the computer front panel connectors to the motherboard.
Checking the BIOS configuration
The USB ports are controlled by controllers, which can be enabled or disabled through the BIOS. Accordingly, if the connectors do not work, you must check their status in the basic I/O system.
- Reboot the laptop and go into BIOS.
- Open Advanced or Integrated Peripherals. There can be other names, it all depends on the BIOS version.
- In the USB Configuration menu, check the status of your USB Controller (there can be several with different names).
Controllers should be enabled in the BIOS
If the controllers are set to Enabled, they should work. If it has “Disabled” status, you need to change it. To do this, highlight the item with the controller, press Enter and select Enabled in the drop-down list.
