For example, a virus could abuse it to make the computer lose some of the functionality that the typical end-user expects, such as the ability to play media with DRM.
Yet, critics consider the weaknesses not as bugs, but as features. Strictly speaking, none of the known methods disables the ME completely, since it is required for booting the main CPU.
All known methods merely make the ME go into abnormal states soon after boot, in which it seems not to have any working functionality. The ME is still physically Functions of retail management to the current and its microprocessor is continuing to execute code.
The ME is supposed to detect that it has been tampered with, and, if this is the case, shut down the PC forcibly after 30 minutes.
As the project found out, by making unauthorized changes to the ME firmware, it was possible to force it into an abnormal error state that prevented triggering the shutdown even if large parts of the firmware had been overwritten and thus made inoperable.
This mode disables most of ME's functions. Yet it turned out that most machines sold on the retail market can be tricked into activating the switch.
Commercial ME disablement[ edit ] In lateseveral laptop vendors announced their intentions to ship laptops with the Intel ME disabled: Purism previously petitioned Intel to sell processors without the ME, or release its source code, calling it "a threat to users' digital rights" .
In MarchPurism announced  that it had neutralized the ME by erasing the majority of the ME code from the flash memory.
It further announced in October  that new batches of their Debian -based Librem line of laptops will ship with the ME neutralized via erasing the majority of ME code from the flash, as previously announcedand additionally disabling most ME operation via the HAP bit.
Updates for existing Librem laptops were also announced. Dellin December began showing certain laptops on its website that offered the "Systems Management" option "Intel vPro - ME Inoperable, Custom Order" for an additional fee.
Dell has not announced or publicly explained the methods used. In response to press requests, Dell stated that those systems had been offered for quite a while, but not for the general public, and had found their way to the website only inadvertently.
Effectiveness against vulnerabilities[ edit ] None of the two methods to disable the ME discovered so far turned out to be an effective countermeasure against the SA vulnerability. For about 60 euros, Ververis purchased from Go Daddy a certificate that is accepted by the ME firmware and allows remote "zero touch" provisioning of possibly unsuspecting machines, which broadcast their HELLO packets to would-be configuration servers.
