although the company buy only Dell computers by default , there about 35 China famous brand computers exist due to the history reason. 10 of them are Lenovo computers, most of them are Yang Tian series which produced 3 years ago.

these computer cause us some trouble, while Dell computer cost less than 1 minutes to format, reinstall the os and application automatically by remote install server. the Lenovo computer cost us about 2 hours to do the same task, because it does not support the remote install system. the Lenovo computers seems don't have a built-in pxe chip so that can not be boot from the network.

i m not sure why don't Lenovo put a pxe chip into the computer, but i am sure our IT personnel will reject purchasing Lenovo computers in the future.
