refurbished tech grading guide

HungryPC Certified Renewed βœ…

Quality, working devices sourced typically at the end of business leases from managed environments. Rather than salvaging faulty devices for refurbishment, we focus on renewing high grade devices through comprehensive cleaning, 48 Hour QA testing and upgrading to give these devices a true new lease on life. You’ll benefit from superior longevity and performance than that of most other used devices.

Other Pre-Owned or “Refurbished” πŸ€”

Generally refers to a product that was previously owned and operated, then resold second-hand. There is no guarantee a used device was ever serviced, inspected or tested internally, or that all of it’s functions are working optimally as there are no official standards for refurbishment. Often lacking any future-proofing due to lower specs, or unseen issues such as dust and debris blocking cooling systems.

Other Ex-Lease or Off Lease 🏒

These devices typically were used by a corporate business customer for 3-5 years and then returned at the end of their lease period for replacement with newer models, as businesses are on a routine replacement cycle for their IT Assets. Often these devices are resold ‘raw’ or as-is for enthusiasts or technicians to refurbish, test and upgrade as they see fit.

You wouldn’t buy a car that wasn’t serviced, so why risk it with your tech?

Delivering you the best quality Laptop or PC, with the best possible performance, and premium support is our core focus. You get much better value, longevity and certainty from an HPC Certified Renewed device. Benefit from up to 70% off the cost of when they’re new, whilst being backed by warranty, and friendly, real, human support, for your peace of mind.

Hungry PC are the leaders in providing you more sustainable tech solutions that last. Don’t settle for other pre-owned devices that haven’t been serviced. We ensure your device is dependable and running just like it was new, if not better, due to our intricate QA processes, 48 hour stress-tests and upgrade procedures.


What to look out for when buying Refurbished or Pre-Owned

After decades of experience in the IT repair industry, we have seen that a majority of the “refurbished” or “pre-owned” tech out there is just second-hand e-waste that’s had a factory reset to re-install the operating system and then sent out the door to unsuspecting buyers, often without even physically cleaning the device or any in depth testing. We’ve seen countless devices that were clearly sourced from insurance write-offs with repairs attempted after liquid spills, or parallel imported, low-spec e-waste from other countries resold here for crazy low prices, leaving you with the risk of a very poor quality device, that may look okay from the outside, but contain undiscovered faults, missing functionality or even software in the wrong language. We believe you deserve better value.

Why risk overheating, poor performance, and likely a far lower lifespan than that of an actually refurbished device?

Get the Hungry PC Advantage

We focus on supporting local businesses, and have partnered with suppliers that primarily source Laptops and PC’s within New Zealand that have come off-lease from professional environments, these are the kinds of devices that have been taken care of throughout their life by a dedicated IT team, often they’re kept to a very high standard, and well maintained and cleaned throughout their life. This means we offer you higher-calibre devices from the get-go as they’re not sourced from dubious places.

Hungry PC Advantage – Cleaned, Tested, Fully Loaded, Ready to Go.
Upgraded for a new lease on life, this unit performs better than when it was new.

Each device is individually taken care of by our in-house technicians, throughout our intricate QA procedures they have been fully inspected, cleaned, and tested inside and out. This means that any dust or debris inside the unit that would affect cooling or performance have been removed. A full hardware stress test with our multi point testing system ensures that every core function of the laptop or PC is tested, and that everything is operating at it’s best with the correct software and drivers loaded, so that you can get up and running from the moment you take the machine out of the box. From there, we are able to grade the machine’s condition, note and attend to any issues, or opportunities we find to upgrade the units where necessary, to give our customers the best possible value for money.


Shopping around? 5 Questions to ask before buying a Laptop or PC in NZ

  1. Does it come with an authentic, NZ/AUS electrically certified charger?
    Many cheap laptops are imported from outside NZ as e-waste and come with dangerous aftermarket knock-off chargers, or worse, cheap travel adapters. We guarantee every laptop comes with an electrically compliant, safe power supply. This not only protects your safety, but it protects the longevity of the device from bad power input.
  2. Has it been physically opened and thermally serviced?
    A wipe and fresh software reinstall doesn’t clean out years of dust. If a laptop or PC hasn’t been physically opened, the cooling fans are likely blocked, leading to overheating and a shortened lifespan. Every HPC Certified Renewed device is opened, deep-cleaned, and thermally optimized by us right here in the Waikato.
  3. Will it officially support Windows 11?
    Many “bargain” refurbished devices online have older 6th or 7th Generation processors that require technicians to bypass the system requirements for installation. Microsoft officially requires at least an 8th Generation Intel processor to run Windows 11. We clearly label our devices, so you know you are getting a machine that is truly compatible. With a truly compatible device, you benefit from future updates, without install headaches or sudden loss of functionality.
  4. Has functionality been individually verified?
    Bulk sellers often only focus on if the device turns on before pushing it out the door. That is how you end up with a device that has unknown faults with keyboard keys, noisy fans, dead USB ports, corrupt Memory, or a flat CMOS that forgets settings every time you restart. We utilize a comprehensive multi-point diagnostic process and functional stress test to individually test every port, key, camera, and hidden component so it works exactly as it should.
  5. Was the battery physically stress-tested, or just given a quick ‘software’ check?
    Software battery health percentages are notoriously misleading. A battery might report “80% health” but completely shut down after 10 minutes of actual use. We don’t rely on diagnostic guesses. We put our batteries through a minimum one-hour physical, real world load test to ensure they will actually hold a charge when you need them to. Not just playing video or showing a webpage, actually utilizing the hardware to its full capability.

What is the difference between grades?

On each individual product page, you can find the grading of your next device, we implement a β€˜fussy’ grading structure, where often our B grades are even better than what most would expect, we aim to be as transparent as possible to give you the best indication of what you will receive. Be sure to read the condition description, as any important details will be listed for your reference with each unit being individually graded.

A Grade: Units are preloved, with the highest level of cosmetic condition on offer, and perfect functionality.

Often praised for their appearance, our A Grade refurbished devices are some of the best looking devices on the market. These devices are hand picked by us to find the best of the bunch. As they’ve been previously used, they may have some light cosmetic wear when closely inspected such as minor marks/scratches or sometimes small blemishes on outer edges or lids, however the wear on these units is very minimal for their age, specs, and typically what you’d find from very well taken care of devices, from clean, tidy business environments. These devices perform and function extremely well and we found them to have no notable issues during inspection.

Check out hundreds of 5-Star reviews from our valued customers here.


A- Grade: Perfect functionality, discounted for cosmetic imperfections.

These units are in perfect working condition, and offered at a discounted price as they may have more visible cosmetic blemishes, or overall slightly more wear and tear from previous use such as marks, scratches, dings, rub marks or scuffs on screens, lids etc. These often small imperfections are purely cosmetic and do not effect their use, they are still fantastic devices, and offer a cheaper alternative for those who don’t mind some mild wear and tear. Read the condition description on the product page for any notes.


B Grade: Great cost cutting option for those who aren’t worried about cosmetic appearances, or don’t mind a minor fault that wouldn’t effect how they would use the device.

We list these so you can get a still very useful unit, at a much lower price than if they were a higher grade. These units may have significant cosmetic defects, such as cracked plastic or a fault with some aspect of their functionality. We always note exactly what the fault is, so you can decide if it’s a deal breaker, or something that won’t bother you.


C Grade: Sorry, we don’t sell β€˜em!

These are units that have functionality or cosmetic issues that we deem to be unacceptable, where your day-to-day use, or enjoyment of the product would be significantly impacted. We often see these listed as B Grade by other vendors, however if we end up with units like these, we recycle them to recover any useful spare parts.


Our Enterprise-Grade Refurbishment Process

At Hungry PC, we don’t just wipe and ship. We specialize in high-quality, ex-lease business-grade technology. Every single machine goes through a rigorous, standardized 48-Hour Multi-Point QA Procedure in-house at our Hamilton workshop. Our transparent process ensures absolute consistency, traceability, and premium performance for every customer.

1. Sourcing & Secure Asset Processing

  • Business-Grade Selection: We source robust, corporate-grade hardware designed for longevity, outperforming cheap consumer-grade electronics.
  • Asset Tracking: Every unit is individually logged into our inventory system for complete traceability throughout our entire QA process.
  • Secure Data Erasure: All previous storage drives undergo professional-standard, secure data wiping to guarantee absolute privacy, security and compliance, leaving no trace of a previous life.

2. Intricate Diagnostics & Fault Testing

  • Hardware Verification: We perform a comprehensive internal inspection to validate exact hardware specifications and component health.
  • Component Stress-Testing: The CPU, RAM, SSD and motherboard all undergo intensive diagnostic tests to guarantee zero technical faults.
  • Transparent Battery Health Validation: We reject the “software battery health” myth. Instead, every laptop battery undergoes a physical full-load stress test to ensure and grade its reliable, real-world performance.

3. Physical Restoration & Thermal Optimization

  • Deep Cleaning: Robust internal dust removal and external sanitization are performed to ensure optimal thermal cooling and peak performance.
  • Strict Cosmetic Grading: Machines are restored and graded. We hold a strict standard, ensuring our primary stock meets overall an Very Good cosmetic condition.

4. Custom Upgrades & Software Provisioning

  • Performance Upgrades: Where necessary, worn components are replaced. We frequently install brand new Solid State Drives (SSDs) and upgrade RAM to give machines a new lease on life.
  • Genuine OS Licensing: Fresh, clean installations of the latest Operating Systems (such as Windows 11) with all current security updates and drivers.
  • Ready-to-Go Software Suite: Systems are preloaded with essential software (Google Chrome, Zoom, VLC, PDF Reader, Antivirus, and LibreOffice) so you can get to work right out of the box.

5. Sustainability & Post-Sale Support

  • Environmental Impact: By comprehensively renewing these devices, we actively prevent e-waste and reduce carbon emissions compared to manufacturing new computers.
  • The Hungry PC Guarantee: Every system is backed by our comprehensive hardware warranty, lifetime access to our NZ tech support guides, and our industry-first 2-Year Repair Discount program (50% off labour for out-of-warranty services).

Battery Condition

Each laptop comes with a used battery that will still hold a charge and has been tested to last at least one hour or more during full-load stress testing. The vast majority of our laptops offer a very reasonable battery life and under normal use they often will last significantly longer than when they are undergoing a full-load stress test.

Battery Health Definition

Tested OK / Fair – Battery holds a charge and passes our full-load stress test for at least one hour, likely to last longer but has not been tested any further.
Good – Will easily play a full HD YouTube or Netflix Movie at Normal Brightness for 2 hours or more. During less intensive tasks like Word Processing they are likely to last longer.
Excellent – Battery would typically last at least 3-4 hours of playing non-stop YouTube or Netflix movies back-to-back, and likely to last significantly longer during normal use such as web browsing.
Brand New – Battery has been replaced with a brand new one to offer its full capacity.

Due to their nature, battery life varies significantly between each unit we have in stock. We also test each laptop to perform flawlessly when connected to the power. Laptops do not require the battery to be charged whilst plugged in to the charger and can be used all day while plugged in.

The power is in your hands! Choose to save money with the used battery, or if a longer battery life is required, we can supply a new battery replacement with free installation. Since used batteries are a consumable like printer ink or car tires, they are not covered by warranty. If you do require an extra long battery life, simply add the new battery option with your purchase.

Beware of the “Battery Health Percentage” Myth. With years of experience in the industry, we’ve seen countless laptops with dead batteries that report an 80% health rating (or even more) via software tools. This is often a very unreliable way of testing a battery and during our customized testing procedure, they often won’t even last ten minutes, fail our tests, and are then replaced. While others rely solely on this health rating to sell you a laptop, we instead decided to create this far more accurate test, so our customers can get a much better understanding of the battery condition and make an informed decision.


A note on Windows 11 Compatibility

Intel Processors that are at least 8th Generation are currently officially supported to run Windows 11. If your computer or laptop has at least an 8th generation processor, you can enjoy Windows 11 as these units meet the requirements for the official installation and upgrade procedures.

When you are looking for a Windows 11 Laptop or PC, be sure to check if the machine is officially supported, on our product description you can see if the Processor is listed as having official support.

officially supported cpu for windows 11

When you are looking at a machine elsewhere you can compare the processor to the this list of the officially supported Processors from Microsoft to see if the machine you’re buying is fully supported for the official upgrade path. You can also easily determine the generation of most Intel processors by the first digit in the model number. For example…

Intel Core i5 8500 (the 8 represents 8th generation)
Intel Core i7 1165G7 (the 11 represents 11th generation)

Both above processors would be supported. An Intel Core i5 7600 for example would NOT be officially supported as the 7 represents 7th generation, or an i7 6600U would also NOT be supported as the 6 represents 6th generation, etc.

While it is possible to bypass the requirements and run Windows 11 on many β€˜unsupported’ devices that do not have 8th generation processors, we recommend familiarizing yourself with the risks of doing so, as you may experience compatibility issues or the inability to install future updates. Read our article, with everything you need to know about Windows 10 and Windows 11


What are screen Rub Marks?

Most sellers won’t even mention these, but if we find any significant blemishes, we offer these as A- or B Grade options, discounted depending on the severity. Modern and slim laptops are very susceptible to this phenomenon after some use, as due to their portable design, the keyboard will touch the screen when the lid is closed, and can slowly create small blemishes on the screen, such as imprint/rub marks due to the physical contact. These typically won’t effect use and often aren’t even visible unless the screen is off, or you have a solid background displaying, such as a bright, white blank page.
