The Laptop Cannot Hold a Charge
The laptop requires constant charging
Incorrect Battery Settings
Go to CONTROL PANEL > HARDWARE AND SOUND > POWER SETTINGS > SYSTEM SETTINGS. Make sure that your settings for your battery, display and sleep options are set correctly and accordingly. Your device may be set to shut down if the battery is too low or if you close your lid.
The charger is connected to the laptop and your laptop works. As soon as you disconnect the charger, your laptop quits working, regardless of charging time. Your battery is faulty. Replace the battery using this guide.
Device is Overheating
The laptop is loud, sounds irregular, and the bottom is hot
Dust in Vents or Fans
Laptops may overheat due to dust and other materials stuck in the vents or fan. Use an air duster to carefully blow off the dust.
The cooling fan may not be working properly and may need to be replaced. Replace the cooling fan using this guide.
Poor Speaker Quality
You have trouble listening to sounds on your laptop, and the audio sounds distorted
Poor speaker quality may be a result of dirty speaker ports. Use an air duster to manually clean out your speakers. If this does not work, follow this guide to replace your speakers.
Drivers are Outdated
If you are still experiencing sound issues, visit your sound card manufacturer’s website and download the necessary drivers. Go to CONTROL PANEL > HARDWARE AND SOUND > SOUND to find what drivers are located in your laptop.
You are unable to move the mouse, or it is overly sensitive
You may need to adjust your touchpad calibration, which is located in SETTINGS > DEVICES > TOUCHPAD. Make sure you change the sensitivity to your liking and adjust the settings to fit your personal use.
Touchpad Wiring May be Loose
Sometimes the touchpad wiring may need to be replaced. In that situation, you will need to replace the touchpad. You can follow the directions here on how to replace the touchpad on the Lenovo Ideapad Flex 4-1570.
