To perform a factory reset on your Lenovo ThinkPad P51, turn off the laptop, then press the 'Novo' button (small button next to the power button). Select 'System Recovery' from the menu and follow the on-screen instructions to reset your device to factory settings.
If your ThinkPad P51 is not turning on, first ensure the battery is charged. Try a hard reset by unplugging the power adapter and removing the battery, then press and hold the power button for 30 seconds. Reconnect the battery and power adapter, then try turning it on again.
To upgrade the RAM on your ThinkPad P51, first turn off the laptop and unplug it. Remove the screws on the back panel to access the RAM slots. Carefully insert the new RAM module into an available slot, ensuring it is properly seated. Replace the back panel and secure it with screws.
To troubleshoot Wi-Fi issues, first ensure Wi-Fi is enabled on your laptop. Update your network drivers via Device Manager. If the problem persists, run the Windows Network Troubleshooter by going to Settings > Network & Internet > Status and selecting 'Network Troubleshooter'.
To calibrate the battery, fully charge your laptop to 100%, then let it discharge completely until it shuts down. Charge it back to 100% without interruption. This process can help recalibrate the battery meter.
To clean the fan, turn off the laptop and remove the back panel. Use compressed air to gently blow dust out of the fan and vents. Avoid using a vacuum cleaner as it can generate static electricity. Reassemble the laptop once cleaning is complete.
To disable the touchpad, go to Settings > Devices > Touchpad and turn off the toggle. Alternatively, you can disable it via the 'Mouse' settings in the Control Panel or by using the function key combination (often Fn + F8 or similar) on your keyboard.
If the screen flickers, try updating the graphics drivers from the Lenovo website or Device Manager. Ensure your display settings are correct by right-clicking on the desktop and selecting 'Display settings'. Adjust the refresh rate if necessary.
To update the BIOS, first download the latest BIOS update from the Lenovo Support website. Run the downloaded file and follow the on-screen instructions to complete the update. Ensure your laptop is plugged in during this process to prevent any interruption.
If your laptop overheats, ensure it is placed on a hard, flat surface to allow proper ventilation. Clean the vents and fan with compressed air. Update your BIOS and drivers, as these updates can include fixes for overheating issues. Consider using a cooling pad if the problem persists.
