Processor limited to 0,80 GHz

[Jorginho7]

Hi, I have a Hp 15-cx0001la without battery and his processor is limited to 0,80 GHz.

If I install a battery, will the processor frequency increase?

@Jorginho7, Hello and welcome to the HP Support Community!

Thanks for posting your question. I'm here to help you get things back on track.

The issue you're experiencing processor stuck at 0.80 GHz is commonly related to power management limitations when the laptop is running without a battery.

🔍 Why This Happens:

HP laptops, especially gaming models like the HP Pavilion Gaming 15-cx0001la, often throttle CPU performance when:

• The battery is removed or missing
• The system is running on AC power only
• The BIOS or chipset drivers are outdated

This is a hardware-level safeguard to prevent overheating or instability when the system cannot verify proper power delivery.

Recommended Steps to Resolve:

Install a Compatible Battery
Yes, installing a genuine HP battery will likely restore normal CPU frequency scaling. The system uses battery telemetry to manage power profiles.

Update BIOS
Your current BIOS version is F.11 (2018), which is quite old. HP has released newer BIOS updates that improve thermal and power management.

Official HP® Support

• Download the latest BIOS for your model
• Run the installer as Administrator
• Ensure AC power is connected during the update

Install HP Chipset and Power Management Drivers
These drivers help Windows communicate properly with the system firmware.

Official HP® Support

• Select your OS version (Windows 11 64-bit)
• Download and install Intel Chipset Driver and HP Power Management Driver

Check Windows Power Plan

• Go to Control Panel > Power Options
• Select High Performance or HP Recommended
• Click Change plan settings > Change advanced power settings
• Under Processor power management, set Minimum processor state to 100%

Additional Tips:

• Avoid using third-party batteries or chargers.
• If the battery is swollen or damaged, do not install it, replace with a genuine HP part.
• You can also monitor CPU frequency using Task Manager > Performance > CPU or tools like HWMonitor.

I hope the information shared has been useful and resolves your concern.

Wishing you a smooth and hassle-free experience ahead!

Hi, I've tried the steps you suggested, replaced the battery, and installed the latest BIOS, but I'm still having the same problem.

@Jorginho7, Thanks for the update, and I’m sorry to hear the issue persists even after replacing the battery and updating the BIOS. Let’s dig deeper and try to resolve this.

Possible Causes Beyond Battery and BIOS

Thermal Throttling or Power Limit Throttling

• If the system detects overheating or inadequate power delivery, it may lock the CPU to 0.80 GHz.
• This can happen if the AC adapter is underpowered or not genuine HP.

Windows Power Management or Intel SpeedStep Issues

• Sometimes, Windows or Intel drivers mismanage CPU scaling.

Missing or Corrupt Intel Dynamic Platform & Thermal Framework (DPTF)

• This driver is crucial for proper CPU frequency scaling.

Next Steps to Try

Check AC Adapter Wattage

Make sure you're using the original HP 150W or 200W adapter (depending on GPU variant). A lower wattage adapter (e.g., 65W or 90W) can cause CPU throttling.

• If unsure, check the label on the adapter or in BIOS under System Information.

Install Intel DPTF Driver

This driver helps manage CPU thermal and power limits.

• Download and install the Intel Dynamic Platform and Thermal Framework driver.
• Reboot after installation.

Reset BIOS Settings

Sometimes BIOS settings can cause power limits to persist.

• Restart the laptop and press F10 to enter BIOS.
• Go to Exit > Load Setup Defaults.
• Save and exit.

Check CPU Throttling Status with ThrottleStop

ThrottleStop is a free tool that can help diagnose if the CPU is being throttled due to thermal, power, or BIOS limits.

• Download ThrottleStop
• Run it and check if BD PROCHOT, Power Limit, or Thermal Limit is active.
• If BD PROCHOT is enabled, try disabling it (only for testing).

⚠️ Use ThrottleStop cautiously. It’s a diagnostic tool and not officially supported by HP.

Optional: Run HP Hardware Diagnostics

To rule out hardware faults:

• Press Esc during boot, then F2 for HP Diagnostics.
• Run System Test > Extensive Test.
