Keyboard Not Working
Keyboard keys are sticking, typing extra letters, or none at all when pressed. Keyboard is typing letters way later than when key is pressed, or the keyboard is not responding at all.
Dirty Keyboard
The keys may be sticking because of dirt and debris in the physical keyboard. Simply cleaning the keyboard may solve the issue. For example, if one row (a,s,d,f,g,h,j,k,l,;,’,) is getting stuck, then it may be beneficial to remove those keycaps and clean the surrounding keyboard where those caps have been removed.
If cleaning those trouble areas, or the entire keyboard itself, does not work, then the issue is most likely not mechanical, but rather a software issue.
Keyboard Settings
The issue with your keyboard may be due to how the settings are configured. Go to your HP Settings and ensure both the Sticky & Filter Keys are disabled and return to the default keyboard behavior, use the following steps:
- Bin the Settings, click Ease of Access.
- Under Ease of Access, click Keyboard.
- Make sure the Filter Keys switch is set to Off.”
The keys should be more responsive, if neither of those work, the keyboard may need to be replaced.
Damaged or Broken Keyboard
If none of these solutions seem to work, your keyboard may be broken. If the keyboard is broken or damaged, it may need to be replaced.
Laptop Keeps Dying
The laptop battery does not last long, the laptop dies if not plugged in, or dies suddenly at 20-30% battery.
Broken Charger
Check that your charger is working by connecting the charger to the laptop and plugging it into an outlet. If the charger lights up orange, it means that the battery is charging. When the light is white, it means that battery is fully charged.
If the end of the charger does not light up at all, the charger is most likely broken and needs to be replaced.
If the charger works, the issues may be with the battery.
Faulty Battery
If the charger is working properly, most likely there is an issue with the battery, and it may need to be replaced. See our guide on removing the HP Pavilion 15-eg0025nr battery.
Laptop Overheating
The laptop gets too hot and the fans make loud whirring sounds as they try to cool the laptop.
Too Many Programs Running
The computer has to work harder when running multiple applications or playing video games with high graphics.
As a general rule, close applications and internet browsers when you’re not using them to make your laptop run more smoothly.
If you are using your laptop for gaming, you may want to reduce the resolution and prioritize performance over visual effects.
You can adjust the performance, change which applications run.
Poor Ventilation
Inadequate air flow prevents the laptop from being able to cool down properly, try these tips to increase ventilation:
Buy a cooling pad, keep the laptop on a hard, flat surface and avoid leaving it on blankets or any type of cloth.
Dirty Vents
Dirt and debris can clog up the vents, making it harder for the fans to dispel heat.
You can clean the vents with compressed air.
If a quick clean does not fix the problem, your fan may need a deeper clean. You can view our guide on cleaning the vents.
You might also want to take out the fan and clean it.
If the fan is so blocked that it still will not spin after being cleaned, then it needs to be replaced.
Screen not displaying properly
If your laptop turns on, but something appears to be wrong with the screen, there are a couple of reasons why this could be happening. It is important to identify what issues might be causing a particular appearance of your screen.
Black Screen
Restart your computer to make sure that the screen issue is persistent, and not caused by low battery, overheating, or a keyboard issue.
To restart your computer manually, press and hold the power button until the computer shuts off, then press the power button to power on the computer.
Another way to restart your computer is
- select the Windows icon on the Taskbar,
- click on the power button,
- select Restart.
Updating Graphics Driver
If your laptop turns on, but the screen is black and won’t display an image, you probably need to update the graphics driver.
First, to ensure that the graphics driver is the issue, connect the laptop to an external monitor using an HDMI cable and switch the display to the other monitor.
To do this:
- Right click on a blank space in the Desktop, this will show a drop down menu, from this menu select “Display Settings”
- In the Settings window, select Display, then select Multiple Displays.
- From here, select the Detect option, this should make it so the external monitor is recognized by the system, if not already done
- Then, select Rearrange Displays, this will display two boxes as screens with numbers 1 and 2.
- Select the monitor you want to be your main display, and select the “Make this my main display” option
If the image is displayed on the external monitor, then it suggests that the Graphics Driver needs to be updated.
To update the Graphics Driver, click here and install the latest driver.
If updating the Graphics Driver does not solve the issue it is important to consider other possibilities:
Physical Damage to the Screen
If the screen is cracked and large black spots are visible in the screen, it should be replaced.
To replace the screen, use this guide. It would also be helpful to double check wiring connections before the complete disassembly of the screen. Crimped or disconnected cables could make it so the display does not work.
Screen Burn- In
If there are “ghosts” of previous images on the screen, you may have screen burn- in. Burn in is caused by leaving the screen on for too long or leaving the screen on in one specific image for an extended period of time.
To combat screen burn-in, leaving the screen on a white screen, or white screensaver, to potentially remove the permanent discoloration. This may not always work to resolve burn-in.
