HP Omnibook 17-dp0029nf Portable Battery

[Franden]

Hello,

My computer's battery drains on its own while the computer is turned off. After charging the battery to 100%, the computer is completely drained after just 2–3 days of non-use.

I ran a battery diagnostic on the HP website, and the battery shows no issues.

I would like to resolve this problem.

It is an HP Omnibook 17-dp0029nf laptop; the computer is brand new, purchased in September 2026.

Thank you for your reply.

Best regards,

Hi @Franden 

Welcome to the HP Support Community.

Thank you for posting your query.

I understand that your new HP OmniBook 17-dp0029nf loses its battery charge while powered off, with the battery dropping from 100% to completely drained after approximately 2–3 days, even though the HP battery diagnostic reports no issue.

Since the battery diagnostic has passed, this may be related to the system's power-management or shutdown behavior rather than the battery's reported health. To help us narrow this down, could you please confirm the following:

Perform an EC/hard reset

• Shut down the notebook.
• Disconnect the AC adapter and all peripherals.
• Press and hold the Power button for about 15–20 seconds.
• Reconnect the AC adapter and turn the notebook on.
• Fully charge the battery and test the shutdown drain again.

Run HP Hardware Diagnostics

• Turn the notebook off.
• Turn it on and repeatedly press Esc.
• Press F2 for HP PC Hardware Diagnostics UEFI.
• Run the Battery Test and, if available, the Power/AC Adapter Test.
• Record any failure ID.

Check the actual battery discharge rate

• Fully charge the battery to 100%.
• Shut the laptop down completely.
• Disconnect AC power and all peripherals.
• Record the battery percentage.
• Check it again after 24 hours and 48 hours.

Take care and have an amazing day!
