Laptop instantly turns off and restarts automatically

My laptop is a Lenovo with 8GB RAM, a 1TB SSD, and an AMD Ryzen 5 5500U processor (Windows 10 currently, previously I had 11. Restore to 10 as I thought maybe reinstalling a lower version could help solve the problem).

The problem I'm facing is that whenever I'm working on my laptop, it instantly turns off and restarts automatically. I scoured the internet and found some suggestions that it might be due to overheating of the fan. Consequently, I took the laptop to a service center, and they cleaned the inside thoroughly. Additionally, after explaining my problem, they suggested that reinstalling the Windows operating system might solve the issue. I followed their advice and reinstalled Windows, but unfortunately, the problem persists, and it's becoming quite frustrating.

A few days ago, as usual, it turned off, but instead of restarting automatically and returning to the home screen, it got stuck on the boot menu, and I couldn't find a way to bypass it and access the computer. I brought it to the service center again, but they couldn't identify any problem at that time. Today, they informed me over the phone that it might be a chip issue, and they need some more time to thoroughly investigate.

Now, could you please let me know what might be the problem with my laptop?

    Hi agmma,

    Welcome to Microsoft Community.

    I'm Hahn and I'm here to help you with your concern.

    From what you've described, the issue could be caused by various factors. Here are a few possibilities:

    1. Hardware Failure: It might indeed be a hardware issue, such as a faulty component like the motherboard, CPU, or RAM.
    2. Overheating: Despite cleaning the fan, overheating could still occur due to inadequate thermal paste application, a malfunctioning heat sink, or a defective fan.
    3. Power Supply or Battery Problems: An unstable power supply or a faulty battery might cause sudden shutdowns and restarts.
    4. Software or Driver Issue: Although you've reinstalled Windows, a specific driver or software might still be causing conflicts or triggering the shutdowns.
    5. BIOS/UEFI Issue: A corrupted BIOS/UEFI firmware might also cause such problems.

    Given the varied possibilities, it's good that the service center is conducting a thorough investigation. Here are some steps you could take:

    • Check Event Viewer: Windows Event Viewer might have logs detailing the cause of the sudden shutdowns. Look for any critical errors or warnings recorded around the time of the shutdown.
    • Run Hardware Diagnostics: Lenovo laptops often have built-in diagnostics. This can help identify hardware issues.
    • Update Drivers and BIOS: Ensure all drivers are up-to-date, including the BIOS/UEFI firmware.
    • Test without Battery: If possible, try running the laptop without the battery and only connected to AC power to rule out a battery issue.

    Given that the service center mentioned a potential chip issue, it's possible that there is a deeper hardware problem. If the issue persists even after investigating the above possibilities, the service center should thoroughly examine the laptop's components, including the motherboard and processor.

    I hope this helps.  If there is anything not clear, please do not hesitate to let me know.

    Your Sincerely
