No, by some reasons Optical Dics Drives which come with HP machines (and few other vendors) are not region free. I don't play DVD's on computers now because the best you can get is 720 × 480 pixels (native) resolution.
Last century, I bought a Toshiba DVD player for A$800 and it was not a region free. I bought another one for A$79 (10 times cheaper) and I could play all DVD's. It's hard to know why. People were talking "cracks" but sorry, I don't know.
Many external BD/DVD players are region free. You may be able to find an internal one but software may stop it.
Note: Many newer machines won't have ODD at all.
Regards.
