Request for motherboard schematic and component information

[JRmercan]

Hello HP Support Team,

I am using an HP Omen 17-cb1008nt (2019 model). For the past year, I have been experiencing battery discharge during gaming sessions even while the laptop is plugged in. At the same time, the AC adapter becomes excessively hot under gaming load.

I have already replaced both the battery and the AC adapter with new original HP parts, including a higher-capacity original adapter, but unfortunately the issue still persists.

Based on my observations, the battery discharge appears to be caused by instantaneous high wattage power spikes during gaming workloads. During standard benchmark or synthetic stress tests, I do not encounter this issue, likely because those tests do not generate the same transient load behavior as real gaming scenarios.

I strongly suspect that the issue may be related to aging or degraded charging/input power circuitry components on the motherboard, such as charging ICs, input MOSFETs, or power delivery related components.

Unfortunately, HP Türkiye has not been able to provide me with sufficient technical assistance regarding this issue.

What I need from your side is technical information that would help me perform a comprehensive hardware-level diagnosis of my device. At minimum, I would greatly appreciate access to:

Motherboard schematic diagrams

Boardview files if available

List of motherboard components and power delivery ICs

Charging/input power stage documentation

Due to current computer pricing in Türkiye, replacing the entire laptop is unfortunately not financially possible for me. If I can identify a malfunctioning or degraded component on the motherboard, I may be able to repair the device by replacing the faulty IC or power delivery component.

Any technical assistance or engineering-level documentation you can provide would be sincerely appreciated.

Thank you for your time and support.

Hi @JRmercan,

Thank you for reaching out.

 I understand how it must be to experience battery discharge and overheating of the AC adapter during gaming workloads, even after replacing both the battery and adapter with original HP parts.

For your request: HP does not provide motherboard schematics, boardview files, or component‑level documentation to end users, as these are proprietary engineering materials. 
However, you can access the official Service manual for HP Omen 17-cb1008nt   Click here which contains detailed service information, including disassembly instructions, part numbers, and supported components. This manual is the resource available for diagnosing and servicing your device.

If you suspect degraded power delivery circuitry, we recommend the following steps:

Run HP diagnostics to check system health and power components.
