My HP laptop battery shows 'Bad Cell' in HP Battery Check.

[Anand071]

Respected Sir/Madam,

I am writing to report an issue regarding my HP laptop's battery. Recently, while using my laptop, the battery got stuck at 8% and the device would shut down instantly when the charger was unplugged. To check the problem, I ran the HP Battery Check diagnostic on 22nd of June, which showed the following result:

• Logic State: Bad Cell

• Charge State: OK

This indicated that one or more battery cells had malfunctioned, though the charging system was fine. Based on this, I was concerned that the battery might need repair or replacement.

However, after not using the laptop for a day, I powered it on again with power plugged in and ran the Battery Check tool once more — this time, the result showed normal status, and there was no ‘Bad Cell’ warning displayed.

Due to this inconsistent behavior, I am confused about whether the battery is truly failing or if it was a temporary glitch. I request your kind guidance on whether I should still consider replacing the battery or if this can be ignored.
Thanking you.

Hi there @Anand071, Welcome to HP Support Community!
 

Thank you for reaching out with your concern about the battery. I'm glad to assist you today.

I understand your concern regarding the inconsistent battery diagnostics on your Victus by HP Gaming Laptop 15-fa0000 (680A4AV). I’ll be happy to guide you through this.

What “Bad Cell” Means:

The “Bad Cell” message indicates that one or more cells in the battery are not functioning properly. This can lead to:

• Inability to hold charge
• Sudden shutdowns
• Reduced battery life

Even if the message disappears temporarily, it may still point to intermittent hardware degradation.

Recommended Steps:

Re-run HP Battery Check in HP Support Assistant:

• Open HP Support Assistant → Go to Battery Check.
• If not installed, download it here: HP Support Assistant | HP® Support

Run HP Hardware Diagnostics (UEFI):

• Shut down the laptop.
• Power it on and immediately press Esc, then F2.
• Select Component Tests > Power > Battery Test.
• Note the Battery Status and Failure ID (if any).

Check Battery Health in Windows:

• Open Command Prompt as Administrator.
• Run: powercfg /batteryreport
• This generates a report at: C:\Users\[YourName]\battery-report.html
• Look for Design Capacity vs Full Charge Capacity.

Observe Battery Behavior:

• If the battery still drops to 8% and shuts down, it’s a strong sign of cell failure.

What to Do Next:

If the issue reappears or the battery fails diagnostics:

• The battery likely needs replacement.

If the issue does not reoccur, continue monitoring. However, intermittent failures often worsen over time.

Additional Tips:

• Avoid using the laptop on extreme heat or soft surfaces that block ventilation.
• Keep BIOS and drivers updated via HP Support Assistant.
