Computer Will Not Power On
The laptop does not power on when pressing the power button.
Broken Power Adapter
First, make sure the outlet the laptop is plugged is functional. Next, check the power adapter and be sure to plug it in securely. If the charging light still is not on, the adapter is most likely malfunctioning, and it is probably best to purchase a new power adapter.
Faulty Battery
If the adapter is plugged in and the light on the power adapter is on, connect the adapter to the laptop’s charging port securely. If the laptop only powers on while plugged in, then the battery is likely defective. Replace the battery using this guide.
Keyboard or Keys Not Responding
The keys on the keyboard do not respond, or they appear to be broken, missing, or stuck.
Impaired Keyboard
When keys can’t be pressed, there may be something below the physical key holding it up. To fix this, remove the key and make sure there is nothing stuck below it. Next, wipe off the area underneath with a cotton swab dipped in a slight amount of rubbing alcohol. Once it is sufficiently clean, snap the key back into position.
Faulty Keyboard
If the laptop is powered on, but the keyboard fails to respond, try replacing the keyboard assembly with this guide.
Computer Gets Extremely Hot
The laptop is on, but it is making a loud noise, and the fan is continually running, or it randomly shuts off without notification
Blocked Vent
The air vent on the base of the device may be blocked, causing the computer to overheat. Be sure to use the device on a hard, flat surface to minimize the chances of airflow blockage.
Dusty Fan
Excessive dust can cause the computer to overheat and could be the reason for the fan to malfunction. To fix this, use compressed air to carefully blow the dust off the fan and out of the vents. If this does not seem to help, it may be necessary to hire a professional or to open the device and clean it thoroughly, with compressed air and a lint-free cloth.
Faulty or Broken Fan
If the solution above does not solve the issue, then a fan replacement is recommended due to old age, accidental drop damage, or a malfunctioning fan. To replace a fan, try the following guide.
Inadequate Amount of Thermal Paste
The laptop may not have enough contact between the heat sink and the processor. The cause could be a lack of thermal paste or by having air between the heat sink and the processor. Reapplying thermal paste may fix the issue. It might be prudent to hire a professional to replace the thermal paste, as it is not easy to do correctly nor is it a quick fix.
Audio is Distorted
Sounds on the laptop are distorted or impossible to hear.
Malfunctioning Headphone Jack
Test audio through the laptop’s speakers, then test it using a set of headphones or speakers. If the audio isn’t distorted through the laptop’s speakers, the audio jack may be faulty. Audio cutting in and out can be a sign of a loose audio jack, so be sure that the audio jack is fully set and stable into the computer.
Faulty Driver
If there is distorted audio sound when listening through the laptop’s speakers, the audio driver may be corrupt. Do a Google search for HP Pavilion x360 14m-cd0005dx and navigate to the official HP website (alternatively, click this link). Click “Driver-Audio” and download the appropriate driver. Go to Control Panel -> Device Manager -> Sound Controllers. Click on the sound card and click “Update driver.” Select the updated driver, then restart the computer.
Broken Speakers
If the volume is up but the speakers do not play clear audio, then the speakers themselves may need to be replaced, Try replacing the speakers with this guide.
No Visible Display
The monitor doesn’t show anything, and the computer is powered on.
Disabled Display
Ensure the display is not accidentally disabled. Press and hold one of the “Fn” keys in the lower corner of the keyboard and then, while holding “Fn”, press “F4.” If the display was disabled by accident, then this should re-enable the display. If the problem persists, hold down the Windows key and then push “P” twice. The computer may have been set to “Projector mode;” doing the action above should convert it back to “Computer Only.”
Faulty Motherboard
If the system display remains blank, the motherboard could be malfunctioning. To replace the motherboard, follow this guide.
Distorted Video
The video image is distorted, blurry, or discolored.
Improper Resolution
The computer may have an incorrect resolution setting. It is possible to check resolution settings by right-clicking the desktop and selecting “Screen Resolution.” The resolution should be 1366 x 768.
Out of Date Video Driver
An outdated video driver can cause distorted or flickering videos. To update a video driver, go to this site and download the appropriate video driver (Listed under Driver-Graphics) by checking for the correct operating system and the most recent files posted.
The Blue Screen of Death
The computer turns on but eventually crashes to a blue screen.
Corrupted Operating System
When restarting the computer, if a blue screen with instructions is displayed, follow the directions on the screen. If the instructions do not solve the problem and the laptop crashes again, erase all data on the hard drive and reinstall the operating system.
Malicious Programs
Malware could affect the device. Scan the computer for malware by opening the Windows Security settings, selecting Virus and Threat Protecting, going to Scan Options, and selecting the Windows Defender Offline Scan. Using another virus software, such as Malwarebytes can aid in identifying and removing a virus from a laptop.
Overheating
Overheating can cause the device to crash to a blue screen. There is a more in-depth troubleshooting guide above to help determine issues with an overheating the device but in general, there are a few things that need to be checked to ensure overheating is not the issue.
First, ensure the vent on the base of the device is unblocked. Next, excessive dust can cause the computer to overheat. A total fan replacement is another option. The fan may malfunction due to accidental drop damage, or by simply having a few loose wires. Lastly, the laptop may not have enough contact between the heat sink and the processor. Reapplying thermal paste may fix the issue.
Malfunctioning RAM
The RAM may cause the device to crash to a blue screen. It can also cause a series of beeping while the laptop is running or attempting to boot. Replace the RAM to fix the issue.
Faulty Motherboard
If the system crashes to a blue screen with an error code or one or more beeps occurs while trying to boot the laptop, the motherboard could be malfunctioning. To replace the motherboard, follow this guide.
Sluggish Performance
Slow performance in opening or using programs.
Too Many Background Processes
Ensure that there aren’t too many programs running on the device simultaneously. First, close any unused applications. Next, use the Task Manager (which can be found by clicking the Start button in the taskbar and searching for Task Manager) to stop unwanted processes from running in the background.
Not Enough Space On the Hard Drive
If it takes too long for a program to load, the Hard Drive Disk could be out of space and be malfunctioning. Make sure to clear out files and programs that are out of date or no longer used; to do so, Windows has a built-in feature that can be found by clicking the start button and searching for “Disk Cleanup.” Other programs, such as BeachBit can aid in device cleanup.
Malfunctioning RAM
If the system is operating slowly, either in how long it takes to load or in the usage of a computer program, the RAM could be malfunctioning. Replacing the RAM is generally relatively quick and easy, but hiring a professional would not be out of line in this instance.
Faulty Motherboard
If the system feels sluggish, the motherboard could be malfunctioning. To replace the motherboard, follow this guide
