HP ProBook 455 G1 Troubleshooting
This troubleshooting page will help you diagnose problems with the HP ProBook 455 G1.
Computer Not Charging
The laptop does not retain a charge.
Faulty Charger Cable
Inspect the charger cord to be sure that all parts of the cable are fully connected to each other and that the cord is fully connected to the laptop. Make sure the light on the power adapter block is on when plugged into wall. If the light is not on, then the cable is faulty and a replacement should be purchased.
Check to see if the laptop’s battery is excessively hot. If the laptop’s battery is unusually hot, it will not receive or hold onto a charge efficiently. Power the computer down by pressing and holding the power button until the computer shuts off. Then, remove the battery from the laptop and allow it to cool down and reach room temperature. Removing the battery can be accomplished by following this guide.
If neither of the above solutions were successful in solving the problem, then the laptop may have a faulty battery. The best way to verify this is to check to see if the laptop can only power on when connected to the charger cable. Plug the charger cable into a wall outlet and into the laptop. Then, power on the laptop and leave it be for thirty minutes to an hour. Come back to the computer after that amount of time and unplug the charger cord from the laptop. If the laptop instantly shuts off, then the battery is in fact faulty and must be replaced. Replace the battery using this guide.

Compute is Overheating
The laptop exudes a higher than normal amount of heat.
Lack of Air Circulation
While using your laptop, make sure to keep it on a hard and flat surface, like a desk. Uneven surfaces, like blankets, can block the laptop's vents and/or fans, which restricts the air flow that allows the device to cool itself down.
Excessive use for prolonged periods of time can cause a laptop to overheat. Press and hold the power button to turn the laptop off. Then unplug it from the charger cord and leave it be for enough time so that it can reach room temperature. This break from use allows the laptop to “rest”.
If overheating becomes a frequent problem after only a few minutes of use, inspect your fans. The fans are responsible with keeping the entire laptop’s system cool. Dust and other obstructions could inhibit the fan from performing its duties efficiently. Use a compressed air can to clean these components. Remove the fans for cleaning using this guide.
Computer is Shutting Down
The laptop crashes while in use.
A laptop that is overheating can oftentimes shut itself down in order to prevent damage or corruption. If the laptop has shutdown due to overheating, unplug the laptop from the charger cord if it is connected and remove the battery from the laptop. Separating these components will allow them to cool down faster and “rest”. Removing the battery can be done by using this guide.
A laptop that is shutting down quickly after spending a large amount of time connected to a charger may have a faulty battery. Consider purchasing a replacement battery and replace the faulty battery using this guide.
Viruses or Malware
A computer virus or malware could be the source of the laptop’s shutdowns. Consider installing a safe antivirus diagnostic program on the computer and remove an files that the antivirus software has deemed as harmful to the laptop.
Faulty RAM, or Random Access Memory, can also cause a laptop to experience random shutdowns. RAM is responsible for the storage of short term data. Check the amount of free RAM space that is currently available. Lacking free RAM space can cause performance issues in laptops and can even lead to a laptop shutting itself down. Use the laptop’s operating system to open the “Task Manager” and view if any unnecessary files and programs are using up large amounts of RAM. If there are such programs, “right-click” on these files and select the uninstall option. If there seems to be a good amount of free space available, then the RAM itself may be faulty. Consider replacing the laptop’s RAM using this guide.
Computer Has Blue Error Message
The laptop’s screen displays a blue error message.
A system error message can have an external cause. Remove all the extra hardware that is currently connected to the laptop which include USB drives, CDs, DVDs, and printer cords.
An Internal Cause
A simple way to figure out has caused the laptop to experience the “Blue Screen of Death” is to turn on Safe Mode. Enabling Safe Mode gives the computer the opportunity to run a diagnosis on the operating system in order to pinpoint any issues or problems. To enable Safe Mode, navigate to the search function in the laptop’s operating system. Type in “Safe Mode” and click on the corresponding link. Safe Mode will be enabled, the laptop will then restart in Safe Mode and start checking the system.
Virus or Malware
Viruses can inhibit a computer in severe ways and can lead to Blue Screen. Consider installing safe antivirus software and allow it run a check on the computer. The software will highlight certain files/programs that it views as potentially threatening to the computer. Remove these files/programs.
Issue with Operating System
If none of the previous solutions have fixed the issue, it may be time to consider using the System Restore. The System Restore resets the computer’s operating system to a safe previous version if a recent update of the operating system is causing the problem. Navigate to the computer’s “Control Panel” by using the operating system’s search option. Click on the option titled “System and Security”. Then, click on “System”, then “System Protection” and finally “System Restore”. Follow all the displayed instructions to employ the System Restore. Note: The System Restore does not affect personal files, photos, documents, etc. Do not view this option as a “last resort”.
Hardware issues with the motherboard can lead to your laptop having the Blue Screen. The only way to to ensure all the connections are secure and there is no damage to the motherboard is to disassemble the laptop and physically inspect the it. This can be accomplished by using this guide.
