Samsung PC Diagnostics can check specific components on supported Galaxy Book4, Galaxy Book5, and Galaxy Book6 models—and Samsung documents startup options for running diagnostics even when Windows will not boot. It is a useful first check, not proof that every part of a laptop is healthy. Follow the instructions for your exact model and region, then use the results alongside the symptoms you are seeing.
Check whether your Galaxy Book supports PC Diagnostics
Samsung’s India support guidance, last updated May 28, 2026, documents PC Diagnostics for Galaxy Book4, Book5, and Book6. Samsung notes that availability can change, and this regional guide does not establish availability for every model or country. Check the support page for your exact model before relying on these steps. On Samsung’s US support site, search by the laptop’s model code to find matching manuals, drivers, firmware, software, warranty information, and repair options: Samsung US laptop support.

Run PC Diagnostics from Windows
- Open the app. Search for PC Diagnostics from the Windows taskbar and launch it. If it is installed, it may also be available through Device Care. Samsung says installation on Galaxy Book4 and Book5 may be available through the Microsoft Store.
- Choose the scope. Select Test all for the tests available on your model, or choose an individual component test if your symptom points to one area. These choices are the app’s documented options; Samsung does not claim that one approach is more accurate than the other.
- Complete any prompted actions. Some checks require you to interact with the laptop—for example, press indicated keyboard keys or touchpad and touchscreen areas, listen to both speakers, or record and replay microphone audio.
- Review the result. Samsung shows a blue check mark when completed tests pass. A problem item is marked orange with an exclamation point; select Test again if you want to repeat it. If you stop a run early, the app offers options to continue or restart.
Start diagnostics when Windows will not boot
For supported systems, Samsung documents two ways to open PC UEFI Diagnostics before Windows loads. The keyboard layout and behavior may vary by model.
Crashes, No Sound, or Screen Glitches?
Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minutePC Slower Than It Used to Be?
A free scan shows the junk files, broken settings and background clutter dragging Windows down - then fixes them in one click.Free scan · Windows 10 & 11Use the BIOS menu
- Power on the laptop and repeatedly press and release F2 before the Samsung logo appears.
- In BIOS, select Advanced > PC UEFI Diagnostics.
Use the direct startup shortcut
- Power on the laptop and repeatedly press and release F5 before the Samsung logo appears.
- PC UEFI Diagnostics should open directly.
Samsung documents both routes but does not claim that either produces more accurate results. The BIOS route is useful if you want to follow the visible menu; F5 is the direct option.

Understand which components the tests cover
The available checks vary by model. Samsung lists up to 17 possible test items:
- Mainboard, cooling fan, motion detection sensor, and light sensor
- Storage, touchpad, touchscreen, and keyboard
- Speaker, microphone, and camera
- AC adapter and battery
- Fingerprint sensor, Bluetooth, Wi-Fi, and cellular
Some checks need your participation; wireless tests search for nearby devices or networks. During diagnosis, the app may offer an Enable action for certain devices disabled in Device Manager. The Information tab displays system details including model, BIOS version, serial number, CPU, memory, graphics driver, storage, audio, network, and app version.

Interpret a clean pass without overreading it
A pass means the completed checks reported no problem in the tested items; it does not establish that the laptop is entirely healthy. Samsung explicitly warns that PC Diagnostics “may not diagnose or resolve some PC problems.” Given the utility’s component-specific scope, a symptom can still be software-related, intermittent, model-specific, or outside the checks available on your laptop. If a problem continues despite a clean result, troubleshoot the symptom itself or contact Samsung support.
Troubleshoot a Samsung laptop that runs slowly or freezes
Samsung’s US guide treats slowdown as a broad symptom and focuses first on checking whether hardware may be responsible. Work through these steps in order:

- Check resource use. Press Ctrl + Alt + Delete and open Task Manager. Look for processes using a large share of CPU or memory. End a resource-heavy task only if it is not actively needed.
- Update Windows, Samsung software, and apps. Install current Windows updates and Samsung drivers or support software. Check app publishers for updates to the apps you use.
- Check available storage. Low storage can make programs difficult to run, according to Samsung.
- Restart the laptop. Check whether the slowdown or freezing remains after a restart.
- Consider a factory restore only after backing up your data. Samsung says a complete restore removes software that may interfere with normal operation. Back up important files before proceeding; a USB flash drive is one possible backup destination.
- Request service if the symptom persists. Samsung recommends service when slowdown or freezing remains after a factory reset. Its US support hub includes repair requests and support contact options.
Choose the right Samsung support route
For other symptoms, Samsung’s US laptop support hub groups help under Audio & Sound, Connectivity, Display or Screen, Power & Battery, Samsung Account & Registration, and Software & Apps. Use your model code when looking for instructions or downloads so that the manuals, drivers, firmware, and software match your laptop. The support hub also provides warranty information, repair requests, and ways to contact Samsung: Samsung Electronics America support.
