Hi,

I have a brand-new Acer Swift AI SF14-51 with an Intel Core Ultra 7 258v / 32gb RAM / 1tb SSD for a week that won't startup.

The keyboard lights up, but the screen remains black, no beep no sound.

I already tried to reset the battery with the pinhole button under the laptop, but it didn't change anything.

Would there be any way to force a hard reset?

    I tried the F7 key with an external monitor and still not displaying anything.

    Is there any chance that Windows update tried to push a BIOS update to it? Sometimes those leave it in a weird state…

    The day it happened I did a BIOS update and then an Intel driver update. It might have been what caused the issue.

    Turn off the laptop, unplug the charger, and hold the power button for 15 seconds. If this doesn't work, bring the laptop to the local Acer for warranty.

    Try to get into the BIOS by holding the appropriate key down when you turn the system on… If it allows you in then do a reset to defaults, then save and exit.

    When your PC powers on but shows no display and the keyboard lights don’t turn on, it can indicate several potential issues. Here’s a step-by-step troubleshooting guide you can follow to identify and possibly resolve the problem:

    1. Check Power Supply

    Ensure Power is Connected: Make sure the power cable is securely connected to both the power outlet and the PSU (Power Supply Unit).
    Check Power Switch: If your PSU has a switch at the back, ensure it is turned on.
    2. Inspect Monitor

    Check Monitor Connection: Ensure the monitor is properly connected to the PC. Check both ends of the cable (monitor and PC).
    Test with Another Monitor: If possible, connect your PC to another monitor to rule out a monitor issue.
    Power On Monitor: Ensure the monitor is powered on and set to the correct input source.
    3. Verify Hardware Components

    Reseat RAM: Power off the PC, unplug it, and remove the RAM sticks. Clean the contacts with a soft cloth and reseat them firmly in their slots.
    Check GPU: If you have a dedicated graphics card, ensure it is properly seated in the PCIe slot and that any power connectors are securely attached.
    Inspect Cables: Check all internal cables (especially power cables) and ensure they are connected securely.
    4. Disconnect Peripherals

    Remove All Peripherals: Disconnect all peripherals (keyboard, mouse, USB devices) except for the monitor. This can help identify if a peripheral is causing the issue.
    5. Listen for Beep Codes

    Check for Beep Codes: If your motherboard has a speaker or if you can connect one, listen for beep codes when you power on the PC. These codes can indicate specific hardware issues.
    6. Clear CMOS

    Reset BIOS Settings: You can reset the BIOS by removing the CMOS battery for a few minutes or using the clear CMOS jumper on the motherboard. This can resolve issues caused by incorrect BIOS settings.
    7. Check for Short Circuits

    Inspect Motherboard Mounting: Ensure the motherboard is not shorting against the case. Check that all standoffs are properly placed.
    8. Test with Minimal Configuration

    Boot with Minimal Parts: Try booting with only essential components – one stick of RAM, CPU, and onboard graphics (if available) – to see if it starts up.
    9. Check for Faulty Components

    Test Components: If possible, test your RAM, GPU, and PSU in another working machine to see if they are functional.
    10. Seek Professional Help

    If none of the above steps work, it may be time to consult a professional technician, as the issue could be with the motherboard or CPU.

    If you can't get into the BIOS using the F2 key at power up, you might have to reflash the BIOS. For your SF14-51 there is a procedure for doing that, but it looks like it requires a different BIOS package than what Acer has on their support sites. That means a re-flash is likely to require a trip to the service center. :(
