I pressed the F12 key to enter the bios setup but ended up with a blank screen and computer not booting but it beeps continuously.

Hi @Sanbabat333,

Welcome to HP Support Community.  

Thank you for posting your query, I will be glad to help you.

Continuous beeping on startup, also known as beep codes, is a way for your computer to communicate an error or issue that prevents it from booting properly. 

Here are some general steps you can take to troubleshoot this issue.

Power Off and Disconnect: Turn off your laptop completely and disconnect it from the power source. If you're using a removable battery, remove it.

Check Hardware Connections:

• Make sure all external devices (USB drives, external hard drives, etc.) are disconnected.
• Reseat your laptop's RAM modules and any other removable components.

Check for Loose Cables:

• Ensure that all internal cables, such as those connecting the hard drive or SSD, are securely connected.

BIOS Reset:

• Since you were trying to access the BIOS, it's possible that a change you made caused the issue. Try resetting the BIOS to default settings. On some laptops, this can be done by removing the CMOS battery, but the process can vary.

Check the Beep Codes:

• The number and pattern of beeps you hear can provide information about the problem. Consult your laptop's manual or the support documentation from HP to interpret the beep codes. The beeping pattern is typically a series of short and long beeps.

Inspect for Hardware Issues:

• If you're comfortable doing so, inspect your laptop for any obvious hardware issues, like loose connections, damaged components, or burnt areas on the motherboard.

I hope this helps. 
 

Take care and have a good day.
