HP Pavilion 15 not recognizing battery after RAM upgrade

[LiamMcL]

I recently upgraded my ram on my energy star hp pavilion 15 now it doesnt recognize my battery at all. Ive tried putting the old ram back in and nothing changed. I changed the battery with another stock hp battery but it still doesnt recognize the battery, i have also updated my bios, reset cmos battery, and updated battery drivers in device manager but nothing works. 

the ram i used was a ddr4 sodimm16gb corsair vengeance with 3200mhz

Hi @LiamMcL,

Welcome to the HP Support Community.
 

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

We understand you're experiencing an issue where your HP Pavilion 15 (Energy Star) laptop no longer recognizes the battery after upgrading your RAM to a Corsair Vengeance 16GB DDR4 3200MHz SODIMM module. You've taken all the correct steps, and we’ll help you move forward.

1. Perform a Full EC Reset (Hard Reset)

• Shut down the laptop.
• Unplug the charger.
• Hold the power button for 30–60 seconds.
• Plug in the charger and boot up.

2. Boot Without Battery, Then Reinsert

• Power off and remove the battery (if removable).
• Boot the laptop on AC power only.
• Shut down, reinsert the battery, and boot again.

3. Install HP Support Assistant & Run Battery Check

• Download from: HP Support Assistant | HP® Support
• Run the Battery Check tool to see if the system can detect or diagnose the issue.

4. Try Lower-Speed RAM or Adjust BIOS Settings

• If your BIOS allows it, try manually setting RAM speed to 2666MHz or 2400MHz.
• Alternatively, test with a different brand or lower-speed RAM to see if the issue resolves.

I hope this helps.

Take care and have a good day.
