When a Lenovo laptop charger isn’t detected, the issue is usually caused by an outdated battery driver. Visit the Lenovo website and download the most recent battery driver for your laptop. Once downloaded, install and activate the newly updated driver.
If your Lenovo laptop camera is not turning on, be sure the camera is not obstructed by the lens cover, the camera has been enabled within any platform you are using, the camera has been enabled within the laptop itself, and check for any missing drivers for the camera after installing an update.
For a Lenovo laptop experiencing restart issues, an emergency reboot is typically the most effective solution. You can also complete a refresh of the device, run the power troubleshooter to diagnose any unknown issues, and flush static from the device’s system.
If your Lenovo laptop HDMI isn’t working, run the troubleshooter to find the problem. To do this, go to ‘Settings’ > ‘Update and Security’ > ‘Troubleshoot’ > ‘Hardware and Devices’ > ‘Find and fix other problems’ > ‘Run the troubleshooter’ and click ‘Yes’ if prompted to enter a password.
If your Lenovo laptop is frozen, complete a power drain, reset BIOS to default settings, secure any connectors that have been dislodged, perform a forced reboot, allow proper ventilation to the HDD, and uninstall any new updates if this issue occurs after they have been downloaded.
If your Lenovo laptop isn’t turning on, reset the device by pressing the emergency reset button located on the bottom, complete a hard reset, complete a power drain, check that the RAM sticks have not gone bad, that there are no errors within BIOS, and allow ample charging time.
If your HP is freezing after a Windows update, you can start your troubleshooting process with small tasks. First, look at common issues like having too many windows open at the same time or having too many peripheral devices and accessories attached.
If your Dell laptop is not detecting or recognizing the internal speakers, first check that your default speakers are correctly selected. If they are, then uninstall your audio driver and reboot your laptop. Windows will automatically reinstall a native audio driver to replace the missing one.
A Dell laptop fan that runs when plugged into the charger is possibly a Windows power management issue. The additional heat generated when charging the battery causes the fan to turn on in response to higher internal temperatures. To resolve the problem, change the power plan settings.
Should you hear loud fan noises when your Dell laptop is docked, it is an indication that the dock is hot. If a vent is blocked or the ambient temperature is high, the fans will activate to keep the components cool and prevent damage to your equipment.
