can't boot up, nor access bios, nor boot up option

pavilion dv6
Microsoft Windows 8 (64-bit)

I replaced my old hard drive with a SSD. However, I am unable to go through the steps to install windows.

Once I start the laptop, I can see the following : " primary ( internal ) battery 601 .

When hitting esc to get to startup menu, I get nothing but hp logo and black screen.

So I took the following steps:

  • bought a new external battery
  • bought and replaced the Rtc battery

Then restarted the laptop, This is what I saw :

  • cmos incompatible, a configuration reset is needed, hit enter
  • Once I do, I get the same msg primary ( internal) battery 601
  • same difficulty : cannot access start-up, nor boot up options

By the way, I don't have any manufacturer warranty.

What is next?

Hello @babarnogosan,


Welcome to the HP Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums, I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.


I read your post about the battery issue, and wanted to assist you!  I understand that you already tried replacing both the main, and RTC battery.


To start, can you provide me with the Product Number of the notebook?  Here is a link you can use that will help you find your Model and Product Number:
HP Customer Support - Products


The original error message usually indicates an issue with the main battery of the notebook.  The new message that you are receiving seems to indicate an issue with the RTC battery.  Is the new RTC battery compatible with the System Board?  Did you try resetting/flashing the RTC battery?  Are you able to perform the UEFI hardware test, to check the hardware?  You can use this document to help: HP Notebook PCs - Testing for Hardware Failures (Windows 10, 😎


Have you tried restoring the BIOS to its default settings?  This should allow the system to check the hardware, and may resolve the issue with the RTC battery.  You can review the following document for more information: HP Notebook PCs - Restoring the BIOS
