HP laptop will not boot

[No_Dig56]

My HP 17-cn2083dx laptop crashed while playing a game and now it will turn on but only shows a black screen.  Caps lock blinks 2 slow and 2 fast lights.   I tried a hard reset holding power button for 15-20 seconds.  I cannot remove the battery.  Still does not boot.

Hi @No_Dig56,

Welcome to the HP Support Community.

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

I hear that your HP 17-cn2083dx Laptop crashed while playing a game. A blinking code of 2 slow and 2 fast Caps Lock lights indicates a corrupted BIOS. This error usually occurs after a crash—such as a gaming overload—or a failed system update. Because the battery is internal, you can attempt to force a BIOS recovery or perform a hardware reset.
 

Step 1: Force a BIOS Recovery:
 

Many HP laptops store a backup of the BIOS that can be restored with a specific key combination.
 

1. Make sure the laptop is plugged into the charger.
    
2. Press and hold down the Windows key and the B key at the same time.
    
3. While holding those keys, press and hold the Power button for 2 to 3 seconds.
    
4. Release the Power button, but continue to hold the Windows + B keys for another 10 seconds.
    
5. If successful, the screen will turn on and display a BIOS update screen.
    

Step 2: Clear the CMOS (Hard Reset alternative):

If the above fails, your motherboard's CMOS (which stores the BIOS settings) needs to be reset. Since the battery cannot be easily removed without taking the laptop apart, a local repair technician may need to open the laptop's bottom casing and temporarily disconnect the small internal coin-cell CMOS battery.

I hope this will help.

 

Take care and have a good day.
