Touchpad left click button not working

[account_disabled]

Hi,

I can no longer left-click using the touchpad button on my laptop. The actual touchpad works fine, and so does the right click button. I use the touchpad button quite frequently, so this has become very frustrating. Any advice would be greatly appreciated.

I have tried shutting my computer down and removing the battery, and I have also tried removing the powercord. Neither worked.

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
