Lenovo, responding to recent reporting that its ThinkBook 14 G9 IPL business notebook uses solid-state drives (SSDs) from Yangtze Memory Technologies (YMTC), stressed that the unit dismantled and tested in the report was a German-spec model, not a US version. The company said all notebooks shipped to the US market do not contain SSDs from YMTC, refuting claims that the Chinese supplier had entered the US PC supply chain.
