Usb Ports Do Not Work On Laptop Hp

The reasons why USB ports do not work on a laptop can be in the software or in the hardware. Sometimes all ports do not function at once, and sometimes only one or two. Below, we will consider why such malfunctions appear, and also we will tell you what to do to fix them yourself if you do not need to repair the connector itself.

BIOS configuration check

If such a problem occurs, the first thing to check is whether the USB controllers on the system board have disconnected. They may well turn off independently, and repair of the connector is not required. When the controller suddenly stopped working, you can activate it in the BIOS:

  1. Immediately after starting the download, often press Del, F2 or another function key provided for entering the BIOS on your device.
  2. Find Integrated Peripherals or Advanced (depending on BIOS version).
  3. Select USB Configuration. Here, opposite the lines of the USB Controller, the Enabled parameter should be set. If it is not there, set the desired value yourself and save the current configuration.

The problem can also sometimes occur due to any USB device that needs repair. To determine it, disconnect all devices that use this port. a mouse, a USB keyboard, etc. Try to connect a working flash drive. If problems cease to appear, look for an inoperative peripheral device.

We work with the device manager

Through the “Start” or in another way, go to the device manager. Perhaps one of the group of USB controllers here is marked with a yellow exclamation mark, which is why the device does not work.

You can try to correct the situation in the following way:

  1. Remove the yellow marked controller from the controller;
  2. Reboot the laptop.

At the next start, the system will reinstall all the necessary software, after which the controllers that fail can work again. Sometimes it helps to roll back the OS to the previous state when all the equipment was functioning normally.

USB may be disconnected due to system settings

The laptop’s power management can be configured so that the system itself disconnects the USB connector after a period of inactivity to save battery power. No repairs are required here. In order for the laptop to stop disconnecting the USB input, it’s enough not to allow Windows to change the power settings of the controller, for which:

  1. In the manager, open the serial bus controllers branch, highlight the line of the root USB hub.
  2. Double-click to open the device, select power management.
  3. Clear the check box next to the line that allows the system to disconnect the connector to save power.

Repeat the described steps for each of the USB hubs registered in the device manager.

Problems with the driver on the system board

Sometimes problems with a broken USB connector can be caused by an outdated motherboard chipset driver. The problem is solved by downloading it from a reliable source and subsequent installation. For this:

  1. Find out the model of your motherboard and chipset. If the laptop documentation is not saved, install a diagnostic utility, for example, AIDA64. When you have a chipset from Intel (in most cases this is the case), you can get all the necessary information at by downloading Intel’s proprietary utility for identifying equipment there.
  2. The necessary driver can also be found on the website of the motherboard manufacturer. However, even here it may not be the freshest. Guaranteed the latest version can only be found on the manufacturer’s website of the chipset itself.
  3. Then the driver will have to be unzipped, for example, with 7-Zip utility and installed as a regular application.

If you do not want to bother looking for the latest version of the driver you need, you can simply use the DriverPack Solution application, which automatically recognizes devices with outdated drivers and updates them.

When Windows is to Blame

Sometimes OS crashes are the cause of non-functioning controllers, so Windows itself requires repair. In this case, you need to reinstall. But to be sure of the cause of the malfunction and not to do unnecessary work, check the operability of the USB ports without loading Windows.

To do this, you can, for example, boot the system from any Live CD. If the ports worked as expected in this disk OS, then the problem is definitely in Windows. you can safely reinstall it. If the devices didn’t work when booting from the Live CD, then the problem should be looked for in the hardware already; it may need to be repaired.

So, most often software malfunctions with non-working USB controllers are solved by updating the driver on the chipset or the motherboard itself (which is essentially the same after the north and south bridges on the motherboard were replaced with one chip). Also, the problem often goes away after reinstalling the OS. Otherwise, the controllers, plug-in USB devices may be malfunctioning, or repairs may need to be done on the system board itself.
