Lenovo has halted trade in its shares, "pending the release of an announcement in respect of a discloseable transaction which constitutes an inside information of the Company."
That quote comes from this statement (PDF), the second such document emitted by Lenovo in recent days. The previous statement (PDF) said "the Company is in preliminary negotiations with a third party in connection with a potential acquisition", was widely interpreted to have been issued in response to rumours the company is to buy some of IBM's server business.
Lenovo's also been rumoured to be considering a cash splash to acquire BlackBerry's ravaged body, but with all the speculation about Big Blue of late The Reg thinks the server business buy is a better bet for now.
We'll update this story as the situation develops. ®
