Update BIOS from Lenovo's website
If your Lenovo laptop won't wake from sleep, there are several things you can try. Firstly, check that the mains lead is not plugged in, as this can prevent the laptop from waking up properly. Unplugging the mains before waking it up should allow it to start normally.
If this doesn't work, you can try updating the BIOS. To do this, go to the Lenovo support website and download the latest BIOS update for your specific laptop model. For a 14" Lenovo laptop, the current BIOS version is AUCN45WW. However, be sure to check the Lenovo website for the BIOS version compatible with your laptop model. Once you've downloaded the correct BIOS update, install it on your laptop.
It's important to note that you should install the drivers directly from the Lenovo support website. Using updater tools or installing drivers from other sources could interfere with your laptop's normal operation mode.
If updating the BIOS doesn't solve the issue, you can try other troubleshooting methods. These include turning off Hybrid sleep, turning on/off hibernate, and ensuring all drivers are up to date. You can also try using the "`powerconfig /sleepstudy` troubleshooting tool or the Event Viewer to diagnose and resolve the issue.
Additionally, check your power management settings. Ensure that the "Allow this device to wake the computer" option is selected for the keyboard, mouse, and wireless network adapter (if applicable). This can be found in the Device Manager settings on your laptop.
