SAN JOSE, Calif. — Hewlett-Packard Co. on Wednesday confirmed plans for a corporate overhaul that will combine two of its biggest divisions, printing and PCs, in an effort by new CEO Meg Whitman to turn the troubled tech giant around.

Under the reorganization, which represents some of the biggest changes at HP in years, Whitman is also consolidating global sales, marketing and communications functions that had been spread across different business units.

The announcement does not mention layoffs, although industry experts have said some are likely.
