Battery big problem, need help

[Sebix0_]

HP Omen 16-wd0020nw (i7-13620H,RTX 4060)Hello, I have big problem with battery. Please check https://www.reddit.com/r/laptops/s/XyRzlnL3Dz and help me what can I do. The battery is not 100% dead but it turns off after exactly 1 minute. Also when im plugged in, for 1 minute it shows normal stable white light, but then it blinks red light.

@Sebix0_, Welcome to HP Support Community. 

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

Based on your description, battery turning off after exactly 1 minute, white charging light turning red while plugged in, this behavior strongly suggests a battery fault or firmware-level power management issue.

Here are the steps to diagnose and potentially resolve the issue:

Perform a Hard Reset

This clears residual electrical charge and resets hardware connections:

• Disconnect the AC adapter and all peripherals.
• Press and hold the power button for 15–20 seconds.
• Reconnect the AC adapter and try powering on.

Run HP Battery Check

Use HP's diagnostic tool to test battery health:

• Download and run HP PC Hardware Diagnostics UEFI by pressing F2 repeatedly at startup.
• Select Component Tests > Battery Test.
• If the battery fails, the battery needs to be replaced. 

Interpret Charging Light Behavior

According to HP documentation:

• White light = Fully charged.
• Amber light = Charging.
• Blinking red/amber = Battery error or not charging.

This confirms a battery fault or charging circuit issue.

Additional Tips

• Avoid using third-party chargers or batteries.
• If the laptop works fine without the battery (plugged in), you can temporarily use it as a desktop until the battery is replaced.

I did the „Hard Reset” and then did the Battery test, it says „No battery”, but apparently, when i unplug the AC adaptor, it works? And by the way, when i unplug the laptop, its still showing red blinking light. Like there is no battery found, but the laptop is working and not shutting down. The only thing i think it MAY be the solve is that i opened the laptop 2 weeks ago for paste change, and the battery cable (which i removed during the change for safety) might be not sitting good and the cable got somehow unplugged, but then how does it works when i unplug the ac? It should automatically turn off right?

@Sebix0_, Thanks for the detailed follow-up, this is very helpful in narrowing down the issue.

Based on your observations:

• Battery test shows "No battery" → The system isn't detecting the battery at all.
• Laptop runs on battery when unplugged → The battery is supplying power, but the system doesn't recognize it.
• Red blinking light even when unplugged → Indicates a battery error or communication fault.
• You recently opened the laptop for thermal paste replacement → This is a key clue.

Likely Cause: Battery Cable Not Fully Seated

HP laptops, especially OMEN models, have tight internal layouts. If the battery cable is even slightly misaligned or partially unplugged:

• The system may not detect the battery via firmware.
• Charging and battery status LEDs may behave abnormally.
• Yet, the battery may still deliver power, explaining why the laptop runs unplugged.

Recommended Steps

Open the Laptop Again

Carefully recheck the battery connector:

• Power off the laptop and unplug the AC adapter.
• Remove the bottom cover (use anti-static precautions).
• Locate the battery connector, ensure it's fully seated and aligned.
• Gently press it in and check for any bent pins or debris.

Reconnect and Test

• Reassemble the laptop.
• Plug in the AC adapter.
• Run the battery test again via F2 > Component Tests > Battery.

Try a BIOS update from HP Support:

If the battery still isn’t detected, it could be:

• A damaged battery cable.
• A faulty battery controller.
• A motherboard-side issue.

In that case, please visit the nearest HP authorized service center, the service team will check and assist you.

Yes, i opened it and of course that was the issue - the battery cable was not fully plugged in. Plugged it good this time and it works like it was. Thanks for help!
