By the way, removing the CMOS battery on most newer laptops will not clear the BIOS password.
I have tried installing the newest AI SUITE from Asus driver web, in order to use Asus update but it fails.
In some laptops the CMOS battery could be easily accessed from the bottom, as it shown on the picture below. In some laptops the CMOS battery is hidden under the keyboard. Here’s the most common problem related to the CMOS battery.
Each time you turn off the laptop it resets date and time back to factory defaults.
When you start your computer, you may see a message like "Press F2 for setup." This setup is your BIOS configuration interface.
For more information about configuring your BIOS, see our guide to configuring your BIOS.
The BIOS performs the POST, which initializes and tests your computer's hardware.
Each time the computer is booted, this value, which is a number is checked against the stored value in the CMOS memory.
If these two values are different, it causes a CMOS Checksum error message.
Computer users frequently encounter CMOS Checksum Bad Error for many reasons.
This error may be frustrating, but the good part is that it can be solved easily.
