That is exactly Lenovo's problem. It has no bargain power against its technology suppliers.Can you explain where else they would get the technology like chips?
I don't expect any company, Huawei included, to develop everything in house. But a great company must have something at its disposal that can help the company to defend against hostilities. It is usually means some essential and critical IPs (technologies, know-hows,etc.) in the sectors that matter the most to the company.
Lenovo has nothing.
