The device loses battery percentage at a rapid rate once unplugged from power. Be sure to plug the device in while checking these issues.
A high brightness will drain the battery faster because the brighter screen consumes more power. Lower the brightness to conserve energy.
USB cables can drain the battery quickly, even when the device’s screen is not open. Unplug cables when they are not in use to limit battery drain.
Close some applications to avoid overworking your device. Watching videos, gaming, or using a high energy application can decrease the battery rapidly, so be sure to only keep applications open if they are in use.
Open Lenovo settings and click on the battery icon in the upper left panel. Turn conservation mode off to allow the device to charge to 100%. Conservation mode is automatically on to preserve the battery lifespan, so it will not charge over 60%. If you need a full charge to 100%, turn off conservation mode. Otherwise, keeping the charge between 30% and 60% will prolong battery life.
Plug the power adaptor into the device to charge it. Once removed from power, if it is still draining considerably, replace the battery using this guide.
The device indicator light does not turn green when the power adaptor is in the wall and device.
Unplug and firmly replug the power adaptor into the device and the wall outlet. Wiggle the cord to be sure that it is fully in the device. Check to see if the green indicator light turns on and the device begins charging.
Plug the power adaptor into the device and the wall and check to see if the indicator light turns green and is charging. If it does not, it is possible that the outlet is faulty. Plug it into another outlet and the indicator light should turn green and the device should begin charging.
Check the power adaptor prongs to make sure they are not bent and are intact. Make sure the cord is not cracked and wires are not visible. Next, ensure that the power adaptor is fully plugged into the device and the wall outlet. If the green indicator light does not turn green to signal charging, replace the power adaptor.
Plug the power adaptor into the device and the wall and check to see if the indicator light turns green and is charging. If it is not charging, the battery is faulty. Replace the battery using this guide.
Plug in the device and check to see if the indicator light turns green, signaling that it is charging. If the light does not turn on, the port is faulty. Look inside the port and see if there is extra debris. Use canned compressed air to gently blow dust and debris from the port or carefully pick out lint with a toothpick.
Plug in the device and check to see if the indicator light turns green, signaling that it is charging. If the light does not turn on, the port is faulty. Look inside the port and make sure the pins are straight and intact. If not, replace the port with this guide.
The device will randomly shut off while in use without warning.
In order to prevent damage, the device will shut down to avoid overheating. Check to make sure the vent ports are not blocked and clean them out them out with a vacuum or pressurized air. Make sure to let the device completely cool down before restarting.
Run a hardware diagnostics test. Press the ‘Win + R’ key to open the run diagnostic box. Type ‘mdsched.exe’ and hit enter to start. Choose to restart the device and check for problems. You will want to use CrystalDiskInfo and the Intel Processor Diagnostic Tool to determine the problems. This test will give you results to see if your issue relates to the RAM or motherboard. This can be a hard task depending on how frequent this issue happens.
Check the device for system errors. Go to the Windows Control Panel, Computer Management, Event Viewer, Windows Log, then systems. Check for red exclamation marks that will show you errors with the device, if there are any.
Loose components can cause a short, shutting the device down. Open the device by taking off the Torx screws and the back cover to gain access to the internals. Once inside check for any loose cables or visibly broken parts. Replace any broken parts. Reseat and reconnect any loose cables.
While powered on, images on the device screen flash or the screen turns black.
When performing these steps make sure the laptop has at least 30% battery left and the power adaptor is in the device. Update the Intel Integrated GFX Driver for the Yoga 920-13IKB by going on the Lenovo website. Once updated, download the Firmware External Detection package and firmware for the Yoga 920-13IKB from the Lenovo website. The final step is to update the BIOS which is avaliable on the Lenovo website.
Open up the device by removing the Torx screws on the back cover. Check the connector that plugs into the device’s screen and the motherboard to make sure that it is fully secured.
If the issue is still not fixed there may be an issue with the screen itself. Follow this guide to replace the screen.
The WiFi connection with the router is either inconsistent or disconnected.
Turn WiFi settings off for a few seconds then turn them back on. If restarting your WiFi connections does not improve the connection, go into the driver advanced options and set “roaming aggressiveness” to 5. If issues continue, update or reinstall the Qualcomm Atheros WiFi driver. Updates and newer versions of the Qualcomm Atheros WiFi driver are available online.
Ensure your router is working, nearby, and connected to a power source. If issues continue, try rebooting the router. Then check if your router has QoS (Quality of Service) settings and see if it has the option to Disable WMM Support. If it does, disable it to see if it will resolve the router problems.
The WiFi signal continues to fail after checking computer settings and router connections. Consider replacing the AC Card with a compatible Intel or Thinkpad. Intel’s 8260, 8265, and 9260 cards are all compatible with the Yoga 920-13IKB.
When a finger is on the fingerprint sensor, the device will not unlock.
Ensure that you use the finger that you have stored in the device. If you’re not sure which finger that is, try every one until it works.
Wash your hands to remove extra oil and make sure your finger is dry.
Turn on your device, click on “Device Manager”. Next, click “Biometric Devices”, then update “Synaptics WBDI - SGX”. Restart your device.
To replace the fingerprint sensor, use this guide.
No sound comes from the speakers when it should.
If the audio jack is in use, audio will play through that instead of the device’s speaks. Unplug everything from the audio jack.
Click on the speaker icon in the lower left corner and then click Playback Devices. Verify that your device is not connected to Bluetooth speakers or headphones. Audio will not play from your device’s speakers if there is another connected device. Make sure the playback device is set to internal speakers.
Go to the bottom right of the screen, and click on the volume icon. Make sure the volume slider is at a full or high volume.
If the device can play sound through headphones but it fails after removing the headphones, replace the damaged speakers using this guide.
