I have been reverse-engineering the InsydeH2O firmware used by the Lenovo IdeaPad Gaming 3 15ARH05 (82EY / IP3GAMING-15ARH).

The project started because this model exposes only a very limited BIOS interface, while common unlock sequences such as Fn+R+N do not appear to work reliably on this generation.

So far, I have:

• extracted Lenovo’s official FCCN21WW Windows update package;
• recovered the complete 16 MiB update ROM;
• parsed its AMD PSP directory;
• decompressed and executed the x86 reset-stage image;
• traced its reset loop under QEMU;
• extracted the Setup Utility and reconstructed its IFR;
• confirmed the existence of a separate hidden Advanced form set;
• recovered its GUID, variable stores, offsets and option inventory;
• tested an experimental SREP runtime patch without permanently modifying the firmware.

The hidden menu contains controls for:

• PCIe GPP and power policies;
• SATA/AHCI and RAID configuration;
• TPM and fTPM;
• USB controllers and individual ports;
• ACPI features;
• SVM, SVM Lock and SMM Code Lock;
• DASH and AMD remote KVM;
• Above 4 GB MMIO.

One particularly interesting result is that the Advanced form set is not surrounded by a top-level IFR SuppressIf condition. My current hypothesis is that Lenovo/Insyde hides it through a visibility table or registration logic inside H2OFormBrowserDxe, rather than through a simple “unlock” setup variable.

I also recovered this form-set GUID:

C6D4769E-7F48-4D2A-98E9-87ADCCF35CCC

However, the runtime SREP patch has not exposed the menu yet. The laptop currently runs FCCN19WW, while the analyzed update is FCCN21WW, so differences in modules, patterns or variable semantics may explain the failure.

The repository documents the full process, hashes, extraction commands, QEMU findings, IFR inventory, experimental SREP configuration and suggested next steps:

Update: the hidden Advanced BIOS menu has now been successfully unlocked on the test machine using SREP. This is a runtime unlock and does not require flashing a modified BIOS image.

The method remains experimental and model/firmware-specific. Hidden settings can still cause a brick, boot failure or no-display condition, so do not change unfamiliar options without a verified SPI backup and recovery plan.

I would especially appreciate help from anyone who:

• owns the same 15ARH05 / 82EY model and can reproduce the unlock;
• can test it on other FCCN firmware versions;
• has experience with InsydeH2O, SREP or H2OFormBrowserDxe;
• can help validate and document the exposed settings safely.

Issues, corrections and reproducible test results are welcome.

from an HP Model 14 CF3028LA to a ThinkPad P16s Gen 2 AMD, specs: amd ryzen 7 pro with 780m graphics, 32gb ram and 1 tb ssd.
I know it would be heresy to abandon Windows 11, but I need it for AutoCAD tools.
I tríed with pop_os and apparently it was not good idea but these days I will go for noraba project or any advice?

As title said, I vibecoded an software for my laptop.
The issue:
My laptop, which has AMD Ryzen 5600H CPU and AMD Radeon RX 6500M GPU had an incredibly frustrating heating issue where my hotspot temperature reached 100 degrees without right away, and throttling directly which reduced my fps by 50% almost and again reached 100 degrees, this continued in an cycle.
For this, I tried various methods, locking fps to 48, lowering resolution and graphics, and some of these worked too, but still in games such as where winds meet, elden ring nightreign, the temperatures kept hitting all time high.
Which lead to me trying to look into undervolting, and to my surprise HP Victus in particular has no way (afaik) to undervolt, because it is restricted at a BIOS level.
This lead me to discovering Universal tuning utility and Ryzen controller, which worked great but sacrified much of my performance to keep temperatures in check.
Annoyed by the lack of direct temperature control, i vibecoded an software which directly targets the dGPU hotspot temperature and it honestly been working really well for me.
This leads to me making this post, for this felt too good to be true to work, that i was wondering if i was damaging any of my hardware in the long run with this app.
If anyone can check, if it is problematic or not for the system, and give some opinions about it, it would be much appreciated!

TLDR: I vibecoded an app to keep thermals in check for laptop having AMD Radeon RX 6500M and AMD Ryzen 5600H, and would like opinions about its safety while using, and would like to know if it is damaging my device in any way.

I do not know how compatible it is with other devices.

I’ve recently bought the ASUS TUF A16..
Being from a non tech background i want to learn more about AI from scratch and some minor gaming as well
Kindly let me know how i can make a good use of this laptop

I've been using an old ThinkPad X270 with an awful TN display and weak performance for years. After graduating from high school, I finally had the chance to replace it with an ASUS TX Air 2025 (ASUS TUF Gaming A14).

Needless to say, the upgrade is massive. XDDD

Over the past year, RAM and SSD prices have risen to the point where they're painful to look at, so I couldn't afford the latest models. :(

Since I felt that 1TB might not be enough for my future needs (I like to keep my games on a separate drive), I decided to add a domestic YMTC ZHITAI TiPlus 7100s 1TB SSD, rated for sequential read speeds of up to 7,400 MB/s. Even at a discounted price, it still cost me around $153 USD. Sigh.

Still, it's more than enough for me. The design also caught my eye, and I'm finally able to get my hands on some AAA titles and actually enjoy them. XD

Specifications:

• Ryzen™ AI 7 H 350
• GeForce RTX™ 5060 Laptop GPU 8GB
• 32GB LPDDR5X 7500MHz
• Samsung PM9C1 1TB SSD
• 14-inch 2.5K 165Hz IPS display
• 73Wh battery

Currently using asus vivobook ryzen 5(4000 series), 8gb ram, 512 ssd. Due to recent industrial heavy software, need to upgrade my laptop.
Also low on budget(85k max)

Is it worth the deal?
