Omen laptop 15-en1007na doesn't post

[dead-omen]

Hi there, two days ago my laptop decided to freeze randomly on me. After the freeze, it got stuck on a black screen before hitting any of the splash screens, I have managed to get into it twice after many failed attempts of booting it, on these two successful boots, it randomly froze again a few hours later and proceeded to blackscreen me before posting etc. It's currently not advancing past this black screen at all. I have tried plugging in an external hdmi to no avail, I've also tried hold windows key and B whilst booting with 0 success, the backlight for the screen doesn't even come on. I can hear fans spinning etc. Please advise

Hi @dead-omen,

Welcome to the HP Support Community. 

I'd be happy to help you! 

It sounds like your OMEN 15.6 15.6-inch gaming Laptop PC 15-En1000 is experiencing serious hardware or firmware issues. Since you've already tried some common troubleshooting steps, here are a few more advanced steps to help diagnose and potentially resolve the issue:

Step-by-Step Troubleshooting

Power Reset:

• Disconnect the power adapter and remove the battery (if removable).
• Press and hold the power button for about 15 seconds to discharge any residual power.
• Reconnect the battery and power adapter, then try to power on the laptop.

RAM Reseating:

• If you are comfortable doing so, open the back panel of your laptop.
• Locate the RAM modules and carefully reseat them by removing and reinserting them.
• Ensure they are properly seated in their slots.

Check for Loose Connections:

• While the back panel is open, check all internal connections, particularly those related to the display and storage devices.
• Ensure all cables and connectors are firmly attached.

BIOS Reset/CMOS Battery:

• Locate the CMOS battery on the motherboard (a small, round, silver battery).
• Carefully remove the CMOS battery for about 5 minutes and then reinsert it. This will reset the BIOS settings.

External Monitor:

• Since you've already tried this, ensure you use the correct function key (usually Fn + one of the F-keys) to switch to the external display.
• Verify the external monitor works with another device to rule out monitor issues.

BIOS Recovery Using Key Press Combination:

• Plug in the power adapter.
• Hold down the Windows key and the B key, and then press the power button for 2-3 seconds.
• Release the power button but continue holding the Windows and B keys until you hear beeps or see a BIOS recovery screen.
