Help with Boot Loop Issue on Galaxy Book3 Ultra

Hi everyone,

I appreciate your help.
I have a Galaxy Book3 Ultra, i7 model with an RTX 4050.

Today, when I tried to turn it on, it got stuck in a restart loop at the Samsung logo. The laptop powers on, displays the logo, and immediately restarts. I tried pressing F2 and F10 to access the BIOS, but it didn’t work. The battery and other components seem fine, but the LED light flashes blue.

Does anyone have any other suggestions to fix this issue?

Thanks in advance for your help!

Let's dive into getting your laptop back up and running. Here's a roadmap to tackle the restart loop:

  1. Power Reset: Unplug the charger and remove the battery (if possible). Press and hold the power button for 30 seconds to discharge any residual power. Reconnect the battery and charger, then power it on. This can sometimes clear out glitches.

  2. Try Alternate BIOS Keys: Samsung laptops might respond to different keys. As soon as you press the power button, repeatedly tap F12, Del, or Esc to see if you can access the BIOS menu.

  3. Disconnect External Devices: Remove any USB drives, external hard disks, SD cards, or peripherals connected to your laptop. Occasionally, the system might be trying to boot from an external device and getting stuck.

  4. Inspect the Keyboard: Ensure no keys are stuck or pressed down, especially the function keys or the ones you tried earlier. A stuck key can interfere with the boot process.

  5. Boot from Recovery Media: If you have access to another computer, create a Windows recovery USB drive:

    • Download the Windows installation media from Microsoft's official site.

    • Use the tool to create a bootable USB drive.

    • Insert it into your laptop and try booting from the USB. You might need to change the boot order by accessing the BIOS or use a boot menu key like F9 or F12 during startup.

  6. Reseat Internal Components: If you're comfortable opening up your laptop:

    • RAM Modules: Carefully remove the RAM sticks and reinsert them to ensure they're seated properly.

    • Hard Drive: Check that the hard drive is securely connected.

  7. Reset the BIOS (CMOS Reset):

    • Disconnect all power sources.

    • Locate the CMOS battery on the motherboard—a small, coin-shaped battery.

    • Remove it carefully and wait for about 5 minutes before reinserting it.

    • This resets the BIOS settings to default and might resolve boot issues.

  8. Check for Hardware Failures:

    • A failing hard drive or RAM can cause boot loops.

    • If you have spare components or can borrow from another system, try swapping them out to test.

  9. Professional Assistance: If none of the above steps work, it might be time to consult a professional technician. There could be deeper hardware issues that require expert diagnostics.
