HP omen 15-dh1019nr, no charging light when plugged in

[Mattscloud]

So I recently upgraded my SSD and cloned my OS to the new drive  and afterwards everything worked fine , however shortly after I noticed my laptop wasn't charging as I was reinstalling some games, so I restarted the laptop and it wouldn't sign me into windows , I went into the bios for the boot system and everything seemed to be correct, so I turned the laptop off after exiting the bios and now it won't turn on. When plugged in there's no charging light , I've done a hard reset by holding the power button down for 60s and I've opened it up to check the connections , unplugged the internal battery and tried AC only and even replaced the charging port cable and charger but it still doesn't turn on and I'm honestly out of ideas on what the issue truly is , it's been 6 days since this all started 😞

Hi @Mattscloud 

Welcome to the HP Support Community! We're here to help you get back up and running.

I'm really sorry your Omen 15-dh1019nr has gone completely unresponsive—it’s deeply frustrating, especially after a successful SSD upgrade. You’ve already done a thorough job checking connections, trying AC-only boot, and replacing the charger and port cable. 

Let’s walk through a few deeper steps to help isolate what might be holding the system back.

1. Confirm Power Delivery at the Port

Even with a new charger and cable, it’s worth checking whether power is reaching the board:

• Plug in the AC adapter and observe the charging LED near the port.
• If it’s completely off, try a different wall outlet and inspect the adapter tip for damage.
• If you have access to a multimeter, test the adapter output to confirm voltage delivery.

 

2. Re-seat SSD and RAM

Since the issue began shortly after the SSD upgrade, a misaligned or shorted component could be interfering with power-on.

• Disconnect all power sources.
• Remove the SSD and RAM modules.
• Reinsert them carefully, ensuring full contact with the slot.
• Try powering on again with AC only.

 

3. Disconnect CMOS Battery (if accessible)

Some Omen models have a small coin-cell battery or embedded CMOS circuit.

• Disconnect the internal battery and AC adapter.
• Locate the CMOS battery and disconnect it for 5 minutes.
• Reconnect everything and attempt to power on.

This clears any firmware-level lockup that may have occurred during BIOS access.

 

4. Try Bareboard Boot

To isolate the fault, remove all non-essential components:

• Disconnect SSD, HDD (if present), Wi-Fi card, and any peripherals.
• Leave only the motherboard, CPU, RAM, and power.
• Connect AC and attempt to power on.

If the system powers on or shows signs of life (fan spin, LED blink), reconnect components one by one to identify the fault.

 

5. Use HP UEFI Recovery (if accessible)

If the system shows any LED or fan activity:

• Power off the laptop.
• Press and hold Windows + B, then press and hold the Power button for 2–3 seconds.
• Release all keys and wait up to 30 seconds.

This may trigger a BIOS recovery routine.

Let me know if the system responds to any of these steps. You’ve already done an exceptional job isolating the issue—now we’ll push a little deeper to see if we can bring it back to life.

So I tried most of the options here but couldn't get it to work, ended up taking it to a local repair shop and they checked it out and said the motherboard was dead sadly.  The info here was helpful on narrowing down the issue away from the charger and charging port tho.

New update I was able to get it to load from a bios tool on a USB drive using the windows +  V keys , however it tells me the cmos checksum is invalid and requires a bios reset each time , while it's on it doesn't charge or recognize the battery , I've used the system diagnostic and it comes back as primary battery not available. I can't rollback the bios thro the same tool as it's not recognizing that it's plugged in via external power even tho it is.

So still some issues going on but it's a minor improvement over being entirely unable to boot. Will update further as I try to figure it all out

Thanks for getting back to us @Mattscloud 

Thanks for the detailed update—and I truly admire how persistent and resourceful you’ve been throughout this. Recovering the system via the BIOS tool and reaching a bootable state is a major step forward, especially after complete power loss. 

Let’s build on that progress and focus on stabilizing the BIOS and power recognition.

 

Based on your latest findings:

• CMOS checksum error suggests BIOS corruption or instability.
• Battery not detected and no charging light point to either firmware-level miscommunication or a hardware fault in the power delivery circuit.
• External power not recognized during BIOS rollback attempts confirms the system isn’t registering AC input properly.

 

Next steps to stabilize BIOS and power detection

Perform a full BIOS reset via jumper or embedded method
Since your model doesn’t have a removable CMOS battery, look for a CMOS reset pad or jumper near the memory or SSD slot.

• Disconnect AC and internal battery.
• Short the CMOS reset pads (usually labeled “CMOS” or “RTC”) with a metal tool for 5–10 seconds.
• Reconnect power and attempt boot.
  This can clear persistent BIOS corruption that software tools can’t reach.

Reflash BIOS using HP BIOS Recovery USB

• On another PC, download the BIOS for your model from:
  HP OMEN 15-dh1019nr Drivers and BIOS
• Use the HP BIOS Update and Recovery tool to create a recovery USB.
• Insert into the affected laptop, press Windows + V, then power on.
• Wait for the recovery screen and follow prompts to reflash the BIOS.

Inspect battery cable and connector

• Since the system boots but doesn’t detect the battery, reseat the battery cable.
• Check for bent pins or loose contact on the motherboard side.
• If available, test with a compatible battery to rule out battery failure.

Run diagnostics from HP App (if bootable)

• If you reach Windows, install the HP App for Windows
• Open it > select your device > Tools > Diagnose & Fix
• This may help reset power flags and detect the battery properly.

Monitor for BIOS reset loop

• If the CMOS checksum error persists after flashing, the BIOS chip itself may be unstable.
• In that case, a technician may need to reprogram or replace the BIOS IC.

You're doing everything right—methodical, patient, and focused. 

Let me know how the BIOS recovery goes or if the battery starts responding after reseating. We’ll keep pushing forward until your OMEN is fully back in action.
