Is there a Lenovo BIOS update?
Lenovo System Update:
Lenovo System Update is used to update, and install Lenovo drivers, BIOS and applications. ... Visit our support home page, select the product > click Drivers & software > select System Update. Note: Lenovo recommends running Windows Update before using Lenovo System Update.
Should I upgrade Lenovo BIOS?
In general, you shouldn't need to update your BIOS that often. Installing (or "flashing") a new BIOS is more dangerous than updating a simple Windows program, and if something goes wrong during the process, you could end up bricking your computer.
Please respond to my effort to provide you with the best possible solution by using the "Acceptable Solution" and/or the "Helpful" buttons when the answer has proven to be helpful.
