Can you hear some beeping noises coming from the laptop? If you can only see the manufacturer’s logo, you may be facing a startup issue. Is BIOS accessible? Please tap F2 on startup and check if the BIOS menu will load.
If no button combination is working, turn off the laptop, remove battery and disconnect power cable. Hold the power button for 20 seconds and reconnect the power cable. Turn on the PC. If the same issue appears, try again pressing F2 or F8. Can you see any other menu loading?
