Hi Vijaya,

Thank you for your reply. We are sorry to learn that the issue remains unresolved.

Since the issue is with the number keys, please turn the Num Lock light on and press the keys on the keypad. Then, press and hold the key, while holding the key, press the keys on the keypad. Do the keys work fine when the key is pressed?  After this step, update the System BIOS on your computer by clicking on the link mentioned below.

Follow instructions mentioned below prior to the BIOS update.

• Ensure that the AC Adapter is connected to the computer prior to the BIOS update.
• Disconnect any third party peripherals connected to the computer before performing BIOS update.
• Remove any cd/dvd from the optical drive prior to the BIOS update.
• Do not turn off the computer during the BIOS update.
• Do not restart the computer during the BIOS update.
• Ensure battery charge is more than 10% during BIOS update.

Note: Plug your computer to a good, working wall jack before you update the BIOS. If you experience a loss of AC power or a significant voltage sag/spike during the BIOS flash, you will either have to replace the BIOS chip or motherboard.

Updating the BIOS should resolve the issue. Please keep us posted on the results.

Thanks and regards.
