I dunno if my corporate windows laptop has this feature, though I
can't do anything in near future regarding to this, no time.

In any case it looks like HP stuff is kinda orphaned in PDx86

Hi Kedar,

is there a bugzilla entry open for this? If not, this is a good way to
capture the problem and share details on the system with people that may
be able to help but do not have the hardware platform itself.
