Touchscreen is Unresponsive to Touch

Your touchscreen on your notebook is not responding to your touch commands.

Touchscreen Functions Changed After Upgrading to Windows 10

If you recently updated your operating system to Windows 10 you could be encountering touchscreen issues since the touchscreen functionality has changed. Neither the edge swipe nor the four finger swipe gestures work when running on Windows 10.

Touchscreen Driver is Disabled/Uninstalled

A driver is a piece of software that tells hardware how to run on a certain operating system. If the touchscreen driver is disabled, you essentially have the touchscreen mode off. In order to ensure that the driver is enabled, you must search in your Device Manager for your touchscreen driver and click enable. If the driver is uninstalled, then find the HP recommended driver and install it.

Drivers and Software Need to be Updated (Operating System: Windows 10)

If your driver is out of date, you could be experiencing trouble with your touchscreen. The driver can be easily updated by searching for updates in your search bar in the start menu. If you aren't prompted with updates, then select an option to Check for Updates.

Faulty Screen

Your screen could be faulty and therefore not be responding due to its condition. However, before you go and replace your screen, perform a hard restart of your computer. This could be your answer as sometimes the connections between the BIOS and hardware need to be reestablished.

Computer Does Not Charge

The computer is plugged into the wall but does not display that it is charging

Faulty Outlet

Make sure that the power outlet you are plugging into is working. Try plugging in an appliance, like a light, that you know works.

Line Noise Issues

Unplug the power adapter from the wall, let it sit for 60 seconds, then plug the adapter back in. If the adapter works after this 60-second "rest", you most likely have a line noise issue with your power source. You should reset the adapter periodically by repeating this moment of rest. This issue occurs when the AC adapter's "over voltage protection" feature senses ground noise and then turns off the adapter.

Damaged Power Cable

The power cable itself may be damaged. Check if the cable has any tears in it, particularly by the ends where the cable plugs into the computer, adapter box, or wall plug. If this is the case, replace the adapter entirely.

Damaged Power Port on Computer

It is possible that the pin inside of the circular plug-in portion is bent out of place. Unplug the power cable from the computer and use a flashlight to look inside the computer port to check for this. If this is the case, use a paperclip or other thin device to maneuver it back in place.

Faulty Battery

It may be the case that the battery is faulty. One possible sign of this is that the battery has a bulge. If this is the case, then get a replacement battery and follow our battery replacement guide to install it.

Computer Is Overheating

The computer feels hot to the touch and may have shut off randomly during use.

Dust in Vents or Fans

Computers can overheat due to excessive dust and other materials stuck in the vents or fan. To fix this, use a compressed air duster to carefully blow the dust off the vents and fan.

Worn Out Fans

Over time, some cooling fans might slow down and wear out as the laptop is gets hot, depending on the usage of the laptop. Obtain compatible replacements and swap out the old ones.

Incompatible Component

A new component, such as a hard drive, is added. The extra component causes the power supply to work harder and generate more heat. Extra heat can also radiate off the new component and add to the temperature inside the case.

WiFi is Dropping Signal or Not Connecting

The computer connected before but no longer does. The WiFi connection keeps dropping. The computer was never able to connect to internet.

Home/Office Wireless Network is Off

Confirm that your home/office network is on and broadcasting. To reset your network simply unplug the power directly from modem without turning it off first, wait 10 seconds, then plug it back in and allow it to load. Contact your service provider if network is still not broadcasting.

WiFi is Turned Off on Computer or in Airplane Mode

Click on the WiFi icon in the task bar at the bottom right hand corner of your screen. To confirm that your wireless network card is on, the WiFi button located at the bottom left of the pop up menu should be highlighted.

Home/Office Network May Need to be Setup

If a network has not been set up previously, you may need to do that first to be able to access the internet. Set up a new network, connecting to the WiFi

Drivers May Need to be Updated/Reinstalled

Check to ensure your driver is up to date . Go to start menu and in the search bar, type Device Manager, then select it when it shows up in the search results. Next, select Network Adapters. Under Network Adapters you will see an option for your wireless card which may be labeled as a LAN card or have “wireless" in the name. After selecting this, a box will pop up. At the top of pop up box select the tab labeled Driver. From this tab you can update driver, roll back to a previous version or uninstall and reinstall the driver package. Try updating first and follow the prompts.

Incompatible Software

Electronics and software are finicky. Settings or compatibility can suddenly change. You can attempt to reset the system by doing a system restore. This restores your operating system to an earlier time before the problem presented itself. IMPORTANT: Before attempting this, first backup all your files (pictures, videos, documents, etc.) to a separate external hard drive. Then perform the system restore by typing “reset” into the menu search bar on bottom left of your task bar. Select Reset this PC then follow prompts. This can also be accessed by going to Settings menu, select Update & Security, then select Recovery. Here you will see Reset this PC, after selecting this option you will then follow prompts.

Faulty WiFi Adapter

If all else fails, your problem could be hardware. You may need to replace the wireless card adapter.

Touchpad Not Working Properly

Touchpad has no response to touch commands or is acting erratically.

Grazing the Touchpad

Make sure you are not putting anything on your touchpad or touching your external mouse (if applicable). Be aware that no clothing, jewelry, or accessories are grazing the touchpad when you are working. Always use your finger to control it directly.

Faulty Setting

Go to settings >> device >> mouse or settings >> device >> device manager, check your mouse and touchpad settings, make sure the touchpad is enabled and is set up correctly.

If the setting does not help, you can reboot your computer and launch the Start-up Menu and then select f10 to enter the bios menu. Press f9 to load the defaults (sometimes can be f5, but the menu at the bottom will show the correct key ), and reset the settings to the factory default.

Faulty Driver

Check your drivers to see if they are installed properly for your touchpad. If your drivers are too old or do not fit your model, go visit the HP website to download the latest drivers.

Broken Touchpad

If all else fails, your problem may be hardware related. Consider replacing your touchpad unit.
