Computer Fails to Charge ¶
The laptop will not charge or hold a charge.
Faulty Charger ¶
Ensure that the charger is plugged into a working wall outlet, plugged into laptop properly, and the connections between charger cord and AC adapter are secure. Make sure that the charge light on the laptop is on, indicating there is a charge. If the light is not on and the charger is properly secure, the charger is faulty. Consider purchasing a replacement charger.
Faulty Battery ¶
Plug charger into the laptop for a 30-60 min period. If the laptop dies shortly after unplugging the charger, the battery is faulty. Consider purchasing a new battery. Replace the battery using this guide.
Faulty Charge Port ¶
Check the charge port for damage. Plug in the charger to make sure it fits snuggly in the port, and that the port does not shake. If there is observable damage, shakiness, or trouble plugging in the charger, you may need to replace the charge port. Follow this guide to replace the charge port.
Overheating/Excessively Loud Fan ¶
The laptop base is incredibly hot or loud. It may crash or malfunction frequently. The laptop fails to fully start, returning an error message for CPU FAN.
Lack of Ventilation Space ¶
Ensure that the computer is located in an environment with a flat level surface and that there is at least 6 inches of clearance on all sides of the laptop. A lack of these conditions will lead to the inability of the laptop to cool itself.
Internal Dust Accumulation ¶
Remove accumulated dust from the inside of the laptop through the use of a can of compressed air. The laptop does not need to be disassembled. Rather, simply spray air into the vents on the left side and underside of the laptop. Partaking in this regularly can prevent dust from blocking fans and/or damaging components.
Heavy Usage ¶
Ensure that the computer is only running the necessary programs. More open programs leads to more heat within the computer. To combat this, shut down unused programs and check for any background processes that are using too much CPU power.
Gradual Fan Breakdown ¶
If none of the above solutions solve the problem, or the fan is continuing to make excessive mechanical noise, then there is a chance that the fan itself has physical defects. This is also the situation if you are receiving error code 90f or 90b upon start up. In these cases, it is advised to replace the onboard fan. This can be done by following this guide.
Damaged Component ¶
As a last resort, any damaged components within the laptop can cause the system to gain excess, unnecessary heat. Scanning the computer for any faulty devices can alert you to the possible cause of the problem. Follow this guide for Windows 8/10 or this guide for Windows 7 to determine if there is a malfunctioning device within the laptop. Attempt to replace or repair this device to solve the heating problem.
Programs Frozen or Lagging ¶
Computer is slow or freezes. Programs run slowly, occasionally freeze, and crash.
Internet Connection ¶
If websites load slowly, check your internet connection. Refer to HP 15-D076nr Troubleshooting: Weak Wireless Connection.
Too Many Programs Open ¶
Having too many programs open can slow down or freeze your computer. Close programs that are not being used.
Temporary Files ¶
Windows generates temporary files while in use. These files store settings and data for temporary use. These files will accumulate over time, and could slow down your computer. To clean away temporary files, go to “Start”, and search for “Disk Cleanup.” Running Disk Cleanup could take a minute or two to complete. Running Disk Cleanup weekly is a good way to promote good performance.
A slow or freezing computer could be the result of malware. Download and install an anti-malware application, such as Malwarebytes Anti-Malware. Run a scan using Malwarebytes to clean out any malware from your computer. Restart your computer after the scan is complete.
Not Enough Storage ¶
Having too many programs and files will take up storage space on your hard drive, which could slow down or freeze your computer. Try deleting unneeded and duplicate files from your system, and organize your files into folders.
Uninstall unused or duplicate programs by going to “Start” and search “Control Panel.” Under “Programs”, select “Uninstall a program.” A list will appear of all programs installed on your computer. Select and uninstall unused and duplicate programs.
Not Enough RAM ¶
If your computer is still slow, or if you typically run very heavy programs, consider adding more RAM. Consider following the RAM replacement guide.
Weak Wireless Connections ¶
The laptop has a weak connection or has trouble connecting to the wireless network. Reminder: attempt a manual check on the wireless connection by simultaneously hitting (fn) and (f12) on the keyboard. Wait 30 seconds for the wireless card to fully enable. Conduct this check before and after each troubleshoot.
Reinstall Wireless Connection Driver ¶
If connection is slow or you cannot connect, consider updating your driver here.
Router Connections ¶
Ensure that the home/institution’s wireless router is turned on, as well as the laptop’s wireless connection. If there is no connection, shut down the router for 1 minute. Restart the router.
Check and Reset Wireless Hardware ¶
Resetting the wireless network can resolve connection problems. Turn off laptop; then, unplug all power connections. Wait 5 seconds before powering the laptop back on. Wait until the laptop automatically connects to the wireless connection.
If the laptop does not connect to the wireless network, click on the Network Icon in the notifications area, and select the name of your wireless network. Click connect. If you can connect to the wireless network, you are done. If you do not connect, follow the next step.
Wireless Card ¶
If you cannot find any wireless signal on the laptop, but you can on another device and the wi-fi is on; then consider replacing the wireless card.
Consider following this guide to replace your laptop’s wireless card.
Missing or Distorted Audio ¶
You have trouble listening to sounds on your computer or there is no sound.
Faulty Driver ¶
If the audio sound is missing or distorted when listening through laptop’s speakers, the audio driver may not be working properly. Follow this link to install or re-run the audio software for your laptop.
Faulty Onboard Speakers ¶
If no sound is coming out of your onboard speakers, try using an external set of speakers or headphones with your laptop. If the external set of speakers or headphones produce sound without a problem, your onboard speakers may be faulty. Consider purchasing new onboard speakers. Use this guide to replace them.
Loose Headphone Jack ¶
Test the audio through your laptop speakers, then test the audio using headphones. If the audio is only distorted or missing while listening through headphones, the audio jack or the headphones themselves may be faulty. Audio that cuts in and out, or sounds distorted, is a common sign that the audio jack may be loose. As a result, make sure the audio jack is completely inserted into the laptop.
