Sometimes, BIOS update can leave your Lenovo laptop unresponsive. In this case, A power reset often resolves this issue. If you don’t know how to do that? Here are the guide to fix it.

• Let’s make sure your laptop is off, there is no power signal or power light.
• Disconnect your laptop from the charger and remove the battery (if possible).
• Press and hold the power button for 30 seconds to drain residual power.
