HP Pavilion 15-eg2000– Very high battery drain even after tuning and driver updates

[DJPerfe]

Hello,

I own an HP Pavilion Laptop 15-eg2000 with the following specifications:

• CPU: Intel Core i7-1165G7 (11th Gen)

• RAM: 16 GB

• SSD: 1 TB NVMe (SK hynix BC711)

• GPU: Intel Iris Xe Graphics

• Wi-Fi: Realtek RTL8822CE

• BIOS: F.15 (April 2024)

• OS: Windows 11 Pro 64-bit (24H2, build 26100)

• Battery design capacity: 41,050 mWh

• Full charge capacity: 37,138 mWh (≈ 90% health)

---

⚡Problem

Even with a healthy battery (≈90% capacity, confirmed by multiple reports), the battery drains extremely fast.

• From 100% to 32% in less than 2 hours of light usage (web browsing, Office, no heavy apps).

• BatteryInfoView measurements show ~15–16 W average discharge rate in normal use.

• Real autonomy: 2h–2h30 max, which is far below expectations for this hardware.

• Important: before formatting the notebook and reinstalling Windows, the battery used to last around 4 hours under similar usage. After reinstall, the runtime dropped significantly.

---

🔧What I have already tried

• Updated all Intel drivers (Iris Xe Graphics, Chipset, ME) using Intel Driver & Support Assistant.

• BIOS is already the latest (F.15).

• Windows Power Plan: “Balanced”, CPU max set to 70% on battery.

• Screen refresh rate locked at 60 Hz.

• Brightness at ~40%.

• Battery saver always enabled.

• Tested with and without HDMI external monitor.

• Tested with Wi-Fi enabled/disabled.

• Performed battery calibration (full discharge to ~5% and recharge to 100%).

---

📊Results

• As soon as I use the laptop lightly, consumption goes up to 15–18 W and the battery drains “visibly”.

❓My question

• Is this normal behavior/design limitation of the Pavilion 15-eg2xxx (small 41 Wh battery, Iris Xe GPU, Realtek Wi-Fi), or could it indicate a hardware/firmware issue?

• Could the problem be related to the Windows reinstall (e.g. missing HP-specific drivers or power management tools)?

• Is there any additional tuning, BIOS setting, or HP-specific driver I should try to reduce idle and light-use power consumption?

Thank you in advance for your support.

Best regards,

Hi @DJPerfe,

Welcome to the HP Support Community!

Thanks for reaching out!

We're thrilled to have the opportunity to assist you and provide a solution.

I understand your HP Pavilion 15-eg2000 is draining battery unusually fast (≈2 hours under light use), even after driver and BIOS updates. Let’s go step by step to check whether this is expected for your model (small 41 Wh battery) or if something else is going on.

1. Battery & Design Limits

41 Wh battery capacity is on the smaller side for a 15-inch laptop with an i7-1165G7 + Iris Xe.

Under normal light use, you’d typically expect 4–5 hours, not just 2 hours.

Your 90% battery health is good, so degradation isn’t the main issue.

2. Power Consumption Analysis

You report 15–18 W discharge at idle/light load.

With a 37 Wh usable capacity, that gives ≈2–2.5h runtime — which matches your observed result.

For comparison, a tuned system with this hardware usually idles closer to 6–8 W (which would give 4–5h).
This suggests something is keeping the system from entering low-power states.

3. Possible Causes After Windows Reinstall

Missing HP-specific drivers/utilities (e.g. HP System Event Utility, HP Power Manager, HP CoolSense, HP HotKey Support) can prevent proper power management.

Windows default drivers for components like the Realtek Wi-Fi or Intel Iris Xe may not be optimized.

Background tasks (e.g. telemetry, updates, indexing) may spike consumption right after reinstall.

4. Things to Try

A. Reinstall HP-Specific Software

Go to HP Support → Drivers & Software for your Pavilion 15-eg2000 model.

Install (in this order):

Chipset drivers (HP-provided, not only Intel generic).

Intel Dynamic Tuning Technology (DTT) → critical for power states.

HP System Event Utility.

HP Hotkey Support & CoolSense (if available).

Realtek Wi-Fi from HP site (sometimes optimized differently from Realtek direct).

B. Power Settings in BIOS

Enter BIOS (F10 at startup).

Look for:

Modern Standby (S0ix) / Sleep states → enable if available.

Hybrid Graphics / UMA only → if you don’t game, you can force Intel only.

Disable unused ports (like PXE boot, wake-on-LAN).

C. Windows Settings

Run powercfg /energy and powercfg /sleepstudy in Command Prompt (Admin).

This will tell you what device/process is preventing low-power idle.

In Device Manager → for Wi-Fi and Bluetooth adapters, enable Allow the computer to turn off this device to save power.

Disable Fast Startup (sometimes keeps devices awake).

D. Background Apps

Check Task Manager → Startup tab, and disable non-essential apps.

In Settings → Privacy & Security → Background Apps, limit what runs.

5. If Still High Drain

If power draw never goes below ~15 W, even idle on desktop with no apps open:

Could indicate a firmware/BIOS regression (though F.15 is latest).

Or a hardware fault (e.g. Wi-Fi card stuck in high power state, SSD firmware bug).

Try running on Airplane Mode and see if it drops significantly → if yes, Wi-Fi card is culprit.

Try a clean boot (only Microsoft services) to test.

No, this isn’t “normal” for your Pavilion, you should get closer to 4–5h.

Most likely culprit: missing Intel DTT + HP power management drivers after reinstall.

I hope this helps.

Hi @Kuroi_Kenshi,

thank you for your detailed reply. I carefully followed your suggestions and here are my results:

**Drivers/Software installed (from HP Support page):**
- Intel Chipset Driver – v10.1.19899.859 (Aug 2024)
- Intel Dynamic Tuning Technology (DTT) – v9.0.11701.4428 (Aug 2024)
- Intel Management Engine Interface (MEI) – v2407.6.1.0 (Aug 2024)
- Intel Serial IO Driver – v30.100.2417.30 (Aug 2024)
- HP System Event Utility – installed and working

**Not available for this model:**
- HP Hotkey Support
- HP CoolSense

**Wi-Fi driver:**
- Realtek RTL8822CE 802.11ac PCIe Adapter
- Current driver version: 2024.10.230.2
(probably a generic/newer version from Windows Update, newer than HP’s release)

**BIOS check (F.15, Apr 2024):**
- Disabled *USB Charging*
- Disabled *Network Boot / PXE*
- Fan Always On = Disabled
- No options for UMA-only graphics or Modern Standby available in Pavilion BIOS

**Battery consumption test (20s sampling with PowerShell):**
- Idle/light use (Chrome + PowerShell window open)
- Discharge observed: still 6–14 W, average ~10 W
- Estimated runtime: ~2.7–3 h typical, sometimes up to 3.5–4 h at best
- This is only a slight improvement compared to before (15–18 W constant, ~2h max) and still far from the expected 4–5 h for this hardware.

---

Conclusion / Question:
Even after reinstalling all HP-provided drivers, adjusting BIOS, and following your suggestions, the average consumption hasn’t changed much. Battery life is still limited to about 2.5–3 hours of light use.

Is there anything else you would recommend trying, or should I accept this as the normal behavior/design limitation of the Pavilion 15-eg2000 series?

Thank you

Hi @DJPerfe,

Thank you for the detailed follow-up, I appreciate all the testing and data you’ve shared. I can see you’ve carefully applied all the HP-specific drivers and BIOS tweaks, and yet the battery life still falls short of expectations. Let’s clarify a few points and see what options remain:

1. Realistic Battery Expectation

The Pavilion 15-eg2000 ships with a 41 Wh battery, which is on the smaller side for a 15-inch i7 laptop with Iris Xe graphics.

Even under light usage, 4–5 hours would be ideal, but achieving this requires full utilization of Intel DTT, optimized HP power drivers, and Modern Standby support.

Since Modern Standby and UMA-only graphics options are not available on your BIOS, the system cannot fully enter the lowest power states. This inherently limits runtime.

2. Remaining Factors

Generic or newer drivers (e.g., Realtek from Windows Update) sometimes draw slightly more power than HP-optimized versions.

Background processes: Even with a clean boot, some Windows 11 telemetry and indexing may keep power draw higher.

Iris Xe graphics: Integrated GPU is efficient but still consumes more power than a UMA-only setup when idle/light use.

3. Optional Additional Steps

Intel Graphics Command Center / Intel DTT tuning:

Check that “Battery Mode / Maximum Battery Life” is enabled.

Disable unnecessary devices temporarily:

Bluetooth, SD card reader, webcams, and any USB devices.

Test runtime with Airplane Mode to see if Wi-Fi adapter is a major contributor.

Powercfg analysis:

powercfg /energy and powercfg /sleepstudy can identify any rogue processes or devices consuming power at idle.

Minimal Windows environment test:

Boot in Safe Mode or clean boot (only Microsoft services) to see if idle power drops further.

4. Realistic Outcome

Given the design limitations of the Pavilion 15-eg2000 (41 Wh battery, lack of Modern Standby, integrated graphics), your observed 2.5–3 hours of light use is unfortunately within expected operational range for this configuration, even though the battery is healthy.

So while your results are disappointing, it is likely not a hardware fault, but rather a design limitation of this specific Pavilion model.

Summary:

You’ve done everything to optimize power.

Small battery + design limitations = typical runtime ~2.5–3 hours.

Further tweaks may give minor improvements, but significant gains aren’t feasible without hardware changes.

I hope this helps.

Hi @Kuroi_Kenshi,

thank you very much for your detailed support and for clarifying the design limitations.
I carefully followed all your suggestions (HP-specific drivers, Intel DTT, BIOS checks, background process cleanup, energy/sleep reports) and re-tested battery life.

Unfortunately, the runtime still remains around 2.5–3 hours under light usage (web + Office), even with Battery Saver always enabled and brightness reduced.

At this point I understand it’s not a hardware fault but rather a limitation of this Pavilion 15-eg2000 configuration (small 41 Wh battery + lack of Modern Standby/UMA options).

Thank you again for your time and explanations — at least now I know the results are “by design” and not caused by a faulty battery.

Best regards,
