Laptop immediately shuts down after start

[electro_bayan]

my laptop shuts down right after start.

I suspect it’s BIOS error, because everything inside looks normal.

I just created USB flash to recover BIOS, but even if i press Win+B during startup nothing changes.

Hi @electro_bayan,

Thank you for providing the details.

If your laptop shuts down right after startup, it could be caused by several different factors. Here's a set of troubleshooting steps you can follow to identify and potentially fix the problem:

Disconnect External Devices

External peripherals (like USB drives, printers, or external monitors) might cause conflicts or power issues.

Disconnect all external devices (USB, external hard drives, printers, etc.) and try starting the laptop again.

Check Battery and Power Supply

A faulty battery or power adapter could cause power issues.

Try removing the battery (if possible) and powering on the laptop using just the power adapter.

Alternatively, try using a different power adapter to rule out a faulty charger.

If the battery is removable, try booting up with and without the battery.

Perform a Hard Reset

Temporary system errors might be causing the shutdown.

Power off the laptop completely.

Unplug the charger and remove the battery (if removable).

Hold down the power button for about 15–20 seconds to drain any residual power.

Reconnect the battery and charger, then try to power the laptop on.

Check for Hardware Issues

Run hardware diagnostics on your laptop.

Check for BIOS/UEFI Issues

Try resetting your BIOS/UEFI settings to default. To do this, press the F10 key during startup to enter BIOS/UEFI.

Look for a setting that says Restore Defaults or Load Optimal Defaults and select it.

Save changes and restart the laptop.

Update BIOS/UEFI Firmware

An outdated or corrupted BIOS could cause boot issues.
