The United Nations’ World E-waste Monitor estimates that the world generates over 60 million tonnes of e-waste yearly. Moreover, this quantity is rising 5 occasions as quick as e-waste recycling. A lot of this waste comes from prematurely discarded digital gadgets.
Many enterprises observe a regular three-year alternative cycle, assuming older computer systems are inefficient. Nevertheless, many of those gadgets are nonetheless useful and will carry out nicely with minor upgrades or upkeep. The difficulty is, nobody is aware of what the weak factors are for a specific machine, or what the wanted upkeep is, and the diagnostics can be too expensive and time-consuming. It’s simpler to simply purchase model new laptops.
When shopping for a used automobile, dealerships and particular person consumers can entry every automobile’s specific CarFax report, detailing the automobile’s utilization and upkeep historical past. Armed with this data, dealerships can carry out the required fixes or upgrades earlier than reselling the automobile. And people can resolve whether or not to belief that automobile’s efficiency. We at HP realized that, to forestall pointless e-waste, we have to gather and make out there utilization and upkeep information for every laptop computer, like a CarFax for used PCs.
There’s a specific problem to amassing utilization information for a PC, nonetheless. We’d like to ensure to guard the consumer’s privateness and safety. So, we got down to design a data-collection protocol for PCs that manages to stay safe.
The firmware-level information collector
Fortunately, the sensors that may gather the required information are already put in in every PC. There are thermal sensors that monitor CPU temperature, power-consumption screens that observe energy efficiency, storage well being indicators that assess solid state drive (SSD) put on ranges, efficiency counters that measure system utilization, fan-rotation-speed sensors that detect cooling effectivity, and extra. The hot button is to gather and retailer all that information in a safe but helpful method.
We determined that one of the simplest ways to do that is to combine the life-cycle data into the firmware layer. By embedding telemetry capabilities instantly throughout the firmware, we be sure that machine well being and utilization information is captured the second it’s collected. This information is saved securely on HP SSD drives, leveraging hardware-based safety measures to guard towards unauthorized entry or manipulation.
The safe telemetry protocol we’ve developed at HP works as follows. We collect the essential {hardware} and sensor information and retailer it in a delegated space of the SSD. This space is write-locked, which means solely licensed firmware parts can write to it, stopping unintended modification or tampering. That licensed firmware part we use is the Endpoint Safety Controller, a devoted piece of {hardware} embedded in business-class HP PCs. It performs a essential position in strengthening platform-level safety and works independently from the principle CPU to offer foundational safety.
The safe telemetry protocol collects information from sensors into a bit of {hardware} generally known as an endpoint safety controller, with built-in safety protections. The endpoint safety controller then writes the info to a devoted read-only portion of the stable state drive, the place licensed operating system purposes can entry the info.Mark Montgomery
The endpoint safety controller establishes a safe session by retaining the key key throughout the controller itself. This mechanism permits learn information safety on the SSD—the place telemetry and delicate information are saved—by stopping unauthorized entry, even when the working system is reinstalled or the system surroundings is in any other case altered.
Then, the collected information is recorded in a time-stamped file, saved inside a devoted telemetry go browsing the SSD. Storing these data on the SSD has the advantage of guaranteeing the info is persistent even when the working system is reinstalled or another drastic change in software program surroundings happens.
The telemetry log employs a cyclic buffer design, mechanically overwriting older entries when the log reaches full capability. Then, the telemetry log may be accessed by licensed purposes on the working system degree.
The PCFax
The telemetry log serves as the muse for a complete machine historical past report. Very like a CarFax report for used vehicles, this report, which we name PCFax, will present each present customers and potential consumers with essential data.
The PCFax report aggregates information from a number of sources past simply the on-device telemetry logs. It combines the safe firmware-level utilization information with data from HP’s manufacturing facility and supply-chain data, digital-services platforms, customer-support service data, diagnostic logs, and extra. Moreover, the system can combine information from exterior sources together with accomplice gross sales and repair data, refurbishment accomplice databases, third-party part producers like Intel, and different authentic tools producers. This multisource method creates a whole image of the machine’s whole life cycle, from manufacturing by means of all subsequent possession and repair occasions.
For IT groups inside organizations, we hope the PCFax will convey simplicity and provides alternatives for optimization. Accessing fine-grained utilization and well being data for every machine of their fleet might help IT managers resolve which gadgets are despatched to which customers, in addition to when upkeep is scheduled. This information can even assist machine managers resolve which particular gadgets to switch quite than issuing new computer systems mechanically, enhancing sustainability. And this might help with safety: With real-time monitoring and firmware-level safety, IT groups can mitigate dangers and reply swiftly to rising threats. All of this could facilitate extra environment friendly use of PC assets, chopping down on pointless waste.

We additionally hope that, a lot because the CarFax provides folks confidence in shopping for used vehicles, the PCFax can encourage resale of used PCs. For enterprises and customers buying second-life PCs, it gives detailed visibility into the entire service and assist historical past of every system, together with any repairs, upgrades, or efficiency points encountered throughout its preliminary deployment. By making this complete machine historical past available, PCFax permits extra PCs to seek out productive second lives quite than being prematurely discarded, instantly addressing the e-waste problem whereas offering financial advantages to each sellers and consumers within the secondary PC market.
Whereas HP’s options signify a major step ahead, challenges stay. Standardizing telemetry frameworks throughout various ecosystems is essential for broader adoption. Moreover, educating organizations about the advantages of life-cycle data will likely be important to driving uptake.
We’re additionally engaged on integrating AI into our dashboards. We hope to make use of AI models to research historic telemetry information and predict failures earlier than they occur, akin to detecting growing SSD write cycles to forecast impending failure and alert IT groups for proactive alternative, or predicting battery degradation and mechanically producing a service ticket to make sure a alternative battery is prepared earlier than failure, minimizing downtime.
We plan to begin rolling out these options in the beginning of 2026.
