Ice lake i5-1035G4 GPU throttled on battery

[theslug]

I have an HP 14-DQ1033cl (i5-1035G4 CPU with Iris plus) with the latest F.07 bios and drivers installed, running a new installation of Windows 10 64-bit 1909.

The Iris Plus GPU will not achieve maximum clock when on battery power (1050 Mhz). Instead, it is limited to 750 Mhz, even with all power profile options (including the Intel command center) set to maximum performance on battery. This appears to be a BIOS issue, and applies to all 14-DQ1XXX models with the same motherboard as me.

Anyone with this laptop can reproduce the issue by downloading the latest version of GPU-Z and running a GPU stress test (the one built into GPU-Z works fine... so does Furmark.... or anything else). With the AC adapter connected, the GPU will clock to 1050 Mhz. On battery, 750. The performance difference is very noticeable in games.

@HP - who do I contact to get a firmware engineer working on a BIOS update to correct the problem?

Again, latest drivers installed, new installation of Windows 10 64-bit, all power profiles set to max performance (including the Intel GPU performance options in the power control customization list and in the Intel Command Center application).

Thanks!

I contacted HP support and was assigned a case number several weeks ago. No response.

Please look for a private message from an identified HP contact. Additionally, keep in mind not to publicly post personal information (serial numbers and case details).
