Lenovo IdeaPad Flex 5-1570 Troubleshooting

A flickering black screen has notoriously occurred on battery mode while disconnected from the charger.

Start by contacting Lenovo via their website/phone to be updated on the latest driver for the laptop. This should include the latest Intel and Nvidia graphic drivers available, or research this through Intel’s website with Lenovo bridge. Install all drivers and restart the computer as each install has completed to prevent software conflicts. After driver installation, right click the desktop to reach the Intel Graphics Control Panel. From there, go to “Power”, click “On Battery” and “Disable Panel Self Refresh”.

If that does not work, resort to editing the computer’s power plan. Search “edit power plan” in Windows, click “Change Advanced Settings” > “Display” > “Enable Adaptive Brightness”. Following this procedure, turn off “On Battery” for both drivers. 

The Fans on Your Computer are making an excessive amount of noise

Try to update the BIOS on the Lenovo support website and click “Downloads” under the most recent update for your operating system. Restart your computer once installed.

Enable “Quiet Mode” by booting your computer to BIOS. To boot to BIOS restart your computer and press the ESC, F1, F2, F8, or F10 key. Once there, go to “Configuration Page” and change system performance mode to “Quiet Mode”.

Try opening task manager and checking to see what is taxing your processor and manage program usage to reduce your processor’s temperature. Other issues can be fixed in the Overheating section of the troubleshooting page.

Heat is increased to an excessive amount while working on your laptop.

The vents located under the case allow for proper amounts of air to flow around the fan blades. When dust clogs these vents air cannot sufficiently flow through the fans causing your laptop to heat up. This clogging causes the fans to work harder as well. Get a can of compressed air and point the nozzle directly at the vents. This should remove enough dust to ensure proper ventilation.

When working on your laptop, you want to make sure that there is enough space around it to allow for proper ventilation. Keeping your laptop upright and working on a flat surface can help prevent overheating.

Although obvious sounding, keeping you laptop in a cooler room can actually help resolve problems with overheating.

Try to update the BIOS on the Lenovo support website and click “Downloads” under the most recent update for your operating system. Restart your computer once installed.

Open up the back plate on your laptop and check to see if there is any physical damage to the fan. Follow this guide to see how to replace your damaged fan.

The touch screen does not respond when tapping with fingers.

After being used for a while dust may begin to build up on the screen causing the touch screen function to stop working.  To fix this all you need to do is wipe the screen with a slightly damp cloth or paper towel.

1. Hold the power button for 30 seconds, then restart the computer
2. Go to device manager, locate Human Interface Device, disable and re enable the touch screen, then reboot device.
3. Go to Device Manager, locate Human Interface Device, uninstall touch screen, then reboot.
