HK shares end down on H2 caution; Lenovo slumps

HONG KONG, Sept 1 (Reuters) - Hong Kong shares started the new month on a weak note, falling 1.6 percent in wafer-thin volumes on Monday, as lingering worries over slowing corporate profitability sparked further selling of blue-chip stocks.

Shares in Chinese PC maker Lenovo Group (0992.HK) tumbled to their lowest level in more than five months after Dell (DELL.O) warned that companies worldwide were cutting technology spending.

The benchmark Hang Seng Index .HSI unofficially closed down 348.10 points at 20,913.79.

The China Enterprises Index .HSCE of top locally listed mainland Chinese firms fell 1.9 percent, tracking the 3 percent drop on the Shanghai bourse.
