@hesham7, Welcome to HP Support Community,
Thank you for posting your query; I’m here to help by guiding you through steps to resolve this issue
The error Primary Battery (601) refers to an issue with your laptop's main battery, not the CMOS or internal battery. This error indicates that the measured storage capacity of the main battery is less than 25% of its original capacity.
Here’s how to troubleshoot:
- Shutdown the Laptop.
- Remove the Main Battery.
- Boot the Laptop without the battery installed.
If you still see the error message, it confirms that the main battery is the issue, likely due to a significant decrease in its capacity (less than 25% of its original storage).
The error code 601 is logged in the system and indicates that the battery needs replacement.
