@jaideep5, Welcome to HP Support Community. 

Thank you for posting your query, I will be glad to help you. 
Based on your description, it sounds like your laptop may have suffered moisture damage, which is now triggering multiple system alerts:

1. CMOS Battery Warning
2. Overheating / Vents Blocked Warning
3. Incorrect System Time

Let’s go through the steps to address each issue:

Power Off and Dry the Laptop

Since the laptop was wet:

• Immediately power it off and disconnect all peripherals.
• Place it in a dry, ventilated area for at least 24–48 hours.
• Avoid using a hairdryer or heat source, this can cause further damage.

If possible, place the laptop in a container with silica gel packets to absorb moisture.

CMOS Battery Warning

This usually appears when the internal battery that stores BIOS settings is failing or disconnected.

• After drying, reset the BIOS:
  • Power on the laptop and press Esc or F10 repeatedly to enter BIOS.
  • Set the correct date and time.
  • Save and exit.

If the warning persists, the CMOS battery may need replacement. 

Overheating / Vents Blocked Warning

This could be due to:

• Moisture interfering with thermal sensors.
• Dust or debris in the vents.

Steps:

• Use compressed air to clean the vents.
• Check if the fan is spinning properly.
• Monitor temperatures using HP’s built-in diagnostics:
  • Restart and press F2 to enter HP PC Hardware Diagnostics.
  • Run the System Tests > Thermal Test.

Incorrect Time

This is linked to the CMOS battery or BIOS reset.

• After BIOS reset, ensure Windows is set to auto-sync time:
  • Go to Settings > Time & Language > Date & Time
  • Enable Set time automatically and Set time zone automatically
