Revision as of 04:42, 20 December 2025
Basic Input/Output System, also known as BIOS, is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup)[1].
Generally speaking, a good running computer's BIOS doesn't need to be updated frequently due to the instinct risk of BIOS flashing. However more and more mainstream computer manufactures starts pushing BIOS updates, often without user's consent or against the user's will, causing more issues and paves the way of controlling the device further.
How it works
Pushing the BIOS update as non-optional Windows Update
Traditionally, BIOS updates are done via a USB stick, which contains a FAT32 partition with bootloader and BIOS content. Recently the BIOS firmware is listed under Windows driver updates. Nowadays these updates are no longer under the "optional" category[2][3].
Blocking BIOS downgrade
In some computer models and BIOS versions, downgrade is blocked or "unsupported"[4], preventing the user from regaining lost functionalities.
Removal of previous BIOS download link
Why it is a problem
Retroactive removal of functionalities
Here's a non-exclusive list of removed functionalities:
- ACPI S3 sleep state[5], also known as "deep" sleep or "suspend-to-RAM"
- Undervolting[6], a method of reducing power consumption without decreasing performance
- CPU thermal design power (TDP)[7]
- Fan control.[8]
Reduced reliability/Planned obsolescence
Users reporting increased coil whine after a certain BIOS update[9], possibly reducing reliability and increasing the failure rate.
Due to its unpredictable and forced nature, uncommanded BIOS updates have a higher chance of bricking the computer[10], such as interrupted BIOS update in the user's backpack due to over-temperature or battery depletion.
On some laptops, the battery capacity is restricted by reducing the charging voltage after a BIOS update, causing premature battery endurance decline. This practice is similar to Google Pixel 6a Battery Performance Program but without official announcement.
Undermining ownership
Manufacturers who force BIOS update often claim that blocking downgrade as "security features" to stop "bad player" from accessing the BIOS[4]. This is a classic example of "secure against the user"[11].
Examples
These examples are non-exhaustive, some known instances are currently not listed due to insufficient source(s). All the examples below have BIOS update as non-optional Windows Update.
Dell
Blocked downgrade[4], removed undervolting[6][12], removed previous BIOS download links[13].
Asus
Reduced TDP[7], blocked downgrade, bricked battery.
HP
Disabled ACPI S3 sleep state[5], blocked downgrade.
Lenovo
Disabled ACPI S3 sleep state[14].
Countermeasures
Disabling UEFI Encapsulation
On some computer models, UEFI Encapsulation can be disabled in BIOS settings[3], disallowing the exchange of configuration data between the operating system and the UEFI firmware.
Enabling "Do not include drivers with windows updates" in Group Policy
Using Group Policy editor (gpedit.msc), users are able to exclude driver updates from Windows update[3] since BIOS is often considered under drivers category. However, this method does not grantee success.
Using a free operating system
Free operating systems such as GNU/Linux respect user freedom. BIOS updates can be manually initiated using LVFS/fwupd
Board-level repair
Flashing BIOS firmware on a bricked laptop can be done by using a custom programmer[10].
Non-BIOS mitigation methods
Some functions can be re-enabled without downgrading BIOS. Advanced BIOS[15], OpenCore[16], Smokeless_UMAF[17].
