I recently bought an HP ProBook 4540S. The touchpad works smoothly on the left side. At the right side, scrolling works, but tapping won't.

Is this a software or hardware problem?

Have you installed the current version of the driver for your trackpad? – Ramhound May 8 '13 at 11:19
Yes i hav installed the synaptic touch pad driver but still can't work – Prakash May 8 '13 at 11:21
Have you contacted HP for assistance with this matter? – Ramhound May 8 '13 at 11:24

I finally found that the Synaptics touchpad setup was not compatible with HP 4540S and I tried for setup with HP drivers from the Internet. Now it works properly. It wasn't a hardware issue after all.
