It turns out that Lenovo has code in their BIOS which creates and maintains a backdoor executable in Windows 7 and Windows 8.x installs. Simply wiping the machine when you bring it home to remove the factory crap-ware is not enough to overcome this implementation. This issue is supposed to have been resolved via a recently released patch that doesn't remove but rather disables this 'feature' which is being called the Lenovo Service Engine.

This exploit takes advantage of a Windows feature called Windows Platform Binary Table. This is essentially a method created for the purpose of enabling UEFI bioses to load extra binaries at boot time.

It's August, people are on vacation, and the editors did just put out a cal for help. Perhaps you could answer that call and do the deep dive on all the submissions you're expecting. Slashdot editors do get paid. It's the friends and family of the Soylent editors who pay because they're busy maintaining a site and submission queue instead of spending more time with them. You might consider paying them with help, or gratitude, or at least a little understanding.
Pointing out it was not all models of lenovo would have been sufficient and served the purposes of the discussion and community without knocking the editors.
