Buying a used laptop saves you a lot of money. Not only that, used laptops can also get you the same benefits as new ones - or perhaps even more.
However, your savings do not come without additional risks. You can't just take a seller's word that "this is 100% working" without evidence - unless you want to be left at their mercy in the case something goes wrong.
That's why it's important to do your own testing.
To help you out, here's a list of resources you can use to check all the major parts of a used laptop.
These softwares are the same testing kits that we at LaptopBrokers personally use to ensure the quality of our offerings.
2. Disk Drives (SSD/HDD): CrystalDiskInfo
3. Battery: BatteryCare
5. Processor, Graphics Card, and Motherboard: OCCT
1. System Information
What's my laptop's serial number?
What's the Windows version, is it activated, and more importantly, what's the product key?
These details aren't as easily accessible from Windows system information (systeminfo.exe), so you'll have to do some more digging.
Why not save yourself some valuable time — and some crippling errors — by letting a software do it for you?
Here are two of our suggestions:
Speccy is a small but powerful piece of software that detects the hardware and software characteristics of your operating system. It then displays the results in a neat and simple window.
The advantage of Speccy is that it gathers all necessary information to help you make an informed decision.
Here's what we really like about it:
• Friendly user interface, which makes it easy to navigate
• Also monitors the temperature. In case of overheating problems, you can quickly verify using Speccy
FreePCAudit is a portable, user-friendly, and completely free system information tool for Windows.
This utility provides basic but still useful information on a variety of hardware components. FreePCAudit includes information on installed software as well as active processes.
• Free PC Audit is a portable application. That means it does not need to be installed directly onto the laptop, and can be can kept on a flash drive for checking across several computers.
2. Disk Drives (SSD/HDD)
CrystalDiskInfo is used to read and monitor the health of disk drives.
• Like FreePCAudit, CrystalDiskInfo is a portable application. It does not need to be installed (can be saved in a flash drive instead)
• Health status is visibly shown
BatteryCare not only informs you about the battery's health, but it also monitors when your laptop needs calibration. It tells you of important information such as:
• Designed capacity - the number of watt-hours that the battery was designed to hold
• Total capacity - how many watts/hour it can currently hold
• Wear Level - The wear level is the difference between the designed and total capacity. It is an implicit indicator of battery health. A wear level of 0% for example indicates that the battery is at full capacity.
4. Keyboard & Mouse
PassMark keyboard test allows you to quickly check whether all keys are functional.
• Tests mouse input, backlight, keyboard strokes, and speed
• PassMark Keyboard Test is a 30-day trial software only
• License cannot be transferred via flash drive (you have to install it directly onto laptop)
Like Passmark Keyboard Tester, KeyboardTester.co also checks the keyboard and mouse.
• There is no usage deadline
• Includes a dedicated mouse tester
• Requires WiFi to access
• Presence of ads
5. Processor, Graphics Card, and Motherboard
OCCT allows you to examine low-level specifications such as the processor, graphics card, and motherboard (among others).
OCCT is especially useful if you intend to purchase a laptop for intensive graphics use.
The software allows you to test the graphics to ensure that they are operational and capable of handling your workload.
It's also good for diagnosing your computer.
Mouse jittering? It might be the cause of faulty graphics hardware. OCCT lets you find out.
