Windows 10 My HP pavillion dv6-6145dx laptop keeps shutting off even with the power cable connected

It seems like the issue you are facing with your HP Pavilion dv6 laptop could potentially be related to power supply or overheating problems. Let's address your concerns: 1. Power Supply: Running the laptop with only the power cord should work fine, and it's not necessary to have the battery inserted. However, if the laptop shuts down even when running solely on the power cord, there might be an issue with the power adapter, the power source, or the laptop's power input. - Ensure that the power adapter is working correctly. Check if the adapter light is on when plugged into a power source. - Make sure the power source is stable and providing the correct voltage. - A power supply issue could lead to unexpected shutdowns. If the power converter you are using is not providing consistent power, it can affect the laptop's operation. 2. Overheating: Overheating can also cause laptops to shut down unexpectedly to prevent damage. Check if the laptop feels excessively hot before shutting down. Ensure the laptop's vents are clear of dust and debris and use it on a flat, hard surface to allow proper airflow. 3. Windows Installation: If Windows installation is failing or causing the laptop to shut down during the process, it could indicate software issues. Try creating a bootable USB drive with a fresh copy of the Windows installation and attempt the installation process again. 4. Hardware Diagnostics: Run hardware diagnostics to check the health of the system components. HP laptops often have built-in diagnostics tools accessible through the BIOS or by pressing specific function keys during startup. Considering the symptoms you described, it might be beneficial to address both the power supply concerns and potential overheating issues to see if the laptop stabilizes. If the problems persist, it's advisable to seek a professional technician's assistance to diagnose and repair the laptop.
