HP acknowledged the problem in a blog posted to its TheNextBench.com site on Sunday. Tony Welch, the lead social media strategist for HP's Personal Systems Group, said the company is currently investigating the issue to figure out what's going on.

"The technology we use is built on standard algorithms that measure the difference in intensity of contrast between the eyes and the upper cheek and nose," Welch explains. "We believe that the camera might have difficulty 'seeing' contrast in conditions where there is insufficient foreground lighting."
