As a FWIW: getting into manufacturer mode on bios 2.19


launch regular BIOS by tapping F2 a few times right after boot.

hold Power button on BIOS screen to force a shutdown.

now while the laptop is off, press (in order) F4, 4, R, F, V, F5, 5, T, G, B, F6, 6, Y, H, N.

now press Power and tap F2 a few times to boot into the BIOS again.

you should now see all the tabs that were hidden before.

Should be obvious but I'll say it anyways : don't change settings or values you don't understand, as it very well may brick your laptop, manufacturers hide these settings for a reason. I don't accept any responsibility for any damage caused.


I don't see any way of making the tabs permanently visible, but this gets you in there without an unlocked bios (previously posted ones have evaporated from download sites)

Hello,

I am looking to unlock the advanced menus and remove the Wi-Fi card whitelist on my Lenovo G570 so that I can install an external graphics card (eGPU).

Here are my system details:
- Laptop Model: Lenovo G570
- Current BIOS Version: 40CN33WW (V2.17)
- Motherboard Chipset: HM65

I need the advanced tabs unlocked to manage PCIe speeds and TOLUD memory mapping to resolve potential eGPU resource errors, alongside the whitelist removal so the adapter is recognized.

Thank you in advance for your time and help!
