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 instances as quick as e-waste recycling. A lot of this waste comes from prematurely discarded digital units.
Many enterprises observe a normal three-year substitute cycle, assuming older computer systems are inefficient. Nonetheless, many of those units are nonetheless purposeful and will carry out nicely with minor upgrades or upkeep. The problem is, nobody is aware of what the weak factors are for a specific machine, or what the wanted upkeep is, and the diagnostics could 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 patrons can entry every automobile’s specific CarFax report, detailing the automobile’s utilization and upkeep historical past. Armed with this info, dealerships can carry out the mandatory fixes or upgrades earlier than reselling the automobile. And people can determine whether or not to belief that automobile’s efficiency. We at HP realized that, to forestall pointless e-waste, we have to accumulate and make accessible 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 person’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 accumulate the mandatory information are already put in in every PC. There are thermal sensors that monitor CPU temperature, power-consumption screens that monitor 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 inside the firmware, we be certain 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 vital {hardware} and sensor information and retailer it in a chosen space of the SSD. This space is write-locked, that means solely licensed firmware parts can write to it, stopping unintentional 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 vital position in strengthening platform-level safety and works independently from the primary CPU to supply foundational safety.
The safe telemetry protocol collects information from sensors into a chunk of {hardware} often 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 inside the controller itself. This mechanism allows 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 good thing about 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, robotically overwriting older entries when the log reaches full capability. Then, the telemetry log might be accessed by licensed purposes on the working system stage.
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 patrons with essential info.
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 info 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 companion gross sales and repair data, refurbishment companion databases, third-party part producers like Intel, and different unique tools producers. This multisource strategy creates an entire image of the machine’s complete life cycle, from manufacturing by all subsequent possession and repair occasions.
For IT groups inside organizations, we hope the PCFax will deliver simplicity and provides alternatives for optimization. Accessing fine-grained utilization and well being info for every machine of their fleet might help IT managers determine which units are despatched to which customers, in addition to when upkeep is scheduled. This information may assist machine managers determine which particular units to exchange quite than issuing new computer systems robotically, 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 may facilitate extra environment friendly use of PC assets, slicing down on pointless waste.

We additionally hope that, a lot because the CarFax offers individuals confidence in shopping for used vehicles, the PCFax can encourage resale of used PCs. For enterprises and customers buying second-life PCs, it offers 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 allows extra PCs to search out productive second lives quite than being prematurely discarded, instantly addressing the e-waste problem whereas offering financial advantages to each sellers and patrons within the secondary PC market.
Whereas HP’s options characterize a major step ahead, challenges stay. Standardizing telemetry frameworks throughout numerous ecosystems is vital for broader adoption. Moreover, educating organizations about the advantages of life-cycle data will probably 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, equivalent to detecting growing SSD write cycles to forecast impending failure and alert IT groups for proactive substitute, or predicting battery degradation and robotically producing a service ticket to make sure a substitute battery is prepared earlier than failure, minimizing downtime.
We plan to begin rolling out these options at the start of 2026.
