Symptoms
- Manufacturer logo appears and stays indefinitely
- Never reaches the Windows logo or spinning dots
- Keyboard shortcuts to enter BIOS may or may not respond
- Fans run and the laptop otherwise seems powered on normally
Likely causes
- CommonFailure before Windows even starts loading (pre-boot hang)This stage is controlled by the laptop's firmware, before the OS is involved at all.
- CommonFailing or disconnected storage driveIf the firmware can't find a bootable drive, it can hang at its own splash screen rather than showing an error.
- PossibleFailing RAMBad memory can cause a hang very early, before diagnostic messages appear.
- PossibleCorrupted BIOS/UEFI firmwareA failed firmware update or corruption can freeze the pre-boot process.
- Less commonOverheating or a failing battery/power delivery issuePower instability can prevent the system from progressing past initial power-on.
What to do
- Hold the power button for 10–15 seconds to force a shutdown, then wait a few seconds before powering on again.
- Try repeatedly tapping the key for BIOS setup (commonly F2, F10, Del, or Esc depending on brand) right at power-on to see if you can reach the firmware menu at all.
- If you can reach BIOS, check that the internal drive is detected under storage information.
- If the laptop has a removable battery, remove it along with the charger for 30 seconds, then reconnect and try powering on with just the charger.
- If you recently added or removed RAM, reseat it or restore the original configuration.
- Try booting from a USB Windows installer to see if the PC gets further than the logo screen when trying to boot from external media.
- If BIOS itself is unreachable and the logo never disappears regardless of what you try, this points to a firmware or hardware fault needing professional service.
Tools and parts
- Bootable Windows installation USB drive, to test booting from external media
When to call a pro
If you can't reach BIOS setup at all and the logo never clears, the laptop likely needs professional diagnosis of the motherboard, RAM, or storage connection.
