Computer Cannot Boot, black screen with Blinking Lights

[RichardMrX]

Hi there, 

I have a booting issue with my Envy 4-1030us, currently running Windows 10 home, 20H2 edition, with 8GB RAM, 180GB SSD.

After years of using this wonderful computer, it starts to give me some issues. I replaced the original hard drive to SSD and upgrade the RAM to 8 GB DDR3. After the last attempt to upgrade the eSATA SSD, the computer starts to experience issues. Noticeably it won't start anymore, the computer will turn on, but no beeping sound or any other noise. The power button light is on, as well as F5 and F12 (orange color) lite up. And within 15 seconds or so, the CapsLock starts to blink, 2 blinks interval, and keep ongoing.

I looked up the blinking, and from what I read, it means BIOS corruption issue: Click Here.   

I followed the link provided by another post: Click Here ,   to troubleshoot, and so far, after 2 days of trying, it became unfruitful. 

I wonder if this means more than just BIOS, or perhaps the motherboard is completely fried. I hope to get some answers before I turn in the computer for good.

Thank you for your time and wisdom!

If you suspect your BIOS to be the problem you can download the update from HP site and make a bootable usb to update it.

Before doing that unplug your power and remove battery then hold down Power button for a few seconds and try again to start it w/o the battery.

Thank you for your reply. It didn't even get to the boot screen. I have the boot USB, and it won't go through it either. Currently, it will start, into a black screen, and remain there with Caps Lock blinking twice. That's all the symptoms.

Make sure that USB stick boots on different computer, also make sure that the PC is booting in UEFI compatibility mode. It should be pretty straightforward in your BIOS settings.

Got ya. the issue is that it doesn't even post, and only in black screen. and yes, the USB works on other devices as boot drive.

If your computer does not start, light emitting diodes (LEDs) or beeps can help identify the issue.

If the error that you are getting is for corrupt BIOS, you can try rolling back the BIOS to the previous version and see if it works.
