Windows 25H2 update – S3 sleep mode compatibility issue

Windows 25H2 update – S3 sleep mode compatibility issue

Dear Microsoft Engineering Team, hello!

I recently discovered a long-standing bug in Windows 11: the computer sleep configuration is the system default, and when it goes to sleep or the second time or after restarting, it will be woken up for no reason during sleep. Personally, I think the compatibility of Windows 11 operating system with S3 sleep is not good, especially for desktops and laptops with 2.5G unlimited brand network cards and onboard 2.5G network cards, there are bugs such as misjudgment of network card signals. In addition, after sleep is awakened, the sound card still has a long silence problem, which can only be restored after a period of time. The program itself does not support the wake-up function after investigation, and the commonly used programs will not disturb sleep, and can eliminate program and hardware problems.

I tried the following troubleshooting method

1. Try to reinstall the system and install it cleanly (it cannot be solved)

2: Try to install the latest version of the driver, or even update the BIOS to the latest version (no solution)

3: Replace hardware such as motherboard, memory, power supply, etc., including replacing other brands (unsolvable)

4: Contact Microsoft support and take measures to turn off the wake-on-NIC (temporarily solved, but it affects the wake-on-NIC function, which is inconvenient to use)

At present, I don't think this measure is a good stopgap measure, and the measure has seriously affected my normal use of the network card wake-up function, and at the same time is highly dependent on the sleep function. In addition, when asking for help on social media, I saw that ASUS computer staff found sleep compatibility issues between Windows 11 and 2.5G network cards as early as 2024, and the ASUS onboard Intel i226-v network card motherboard could not enter sleep mode normally (model number ROG STRIX B760-G Gaming D4). At the same time, in order to confirm my judgment, I used the tenth generation desktop of my work unit to install the same system to make a comparison, this host is a 1G network card, after testing, the 1G network card in the default power setting (network card wake-up is turned on by default in the device manager power option), there is no above problem, and combined with the two motherboards I replaced before, both have a 2.5G network card on board, one model is (ASUS PRIME B760M-A), the other is (GIGABYTE). GAMING X DDR4 GEN5), and replace a new motherboard again, the problem is still the same, as long as any 2.5G network card on board of any brand of motherboard, including but not limited to self-installed 2.5G network card (network card wake-up is turned on by default in the device manager power options), there is a sudden misjudgment of Windows 11's network card wake-up signal during sleep and is woken up for no reason. At the same time, others have also reported that the motherboard of the 15th generation platform also has the problem of sleep suddenly being woken up by this system bug, so I would like to share my new discovery with you, looking forward to the letter from your behind-the-scenes engineering team, and at the same time, I would like to ask when this problem can be solved (that is, the problem of wake-up suddenly being woken up by a misjudgment signal when the 2.5G network card is turned on by default to wake up and enter sleep)?

Thank you very much and look forward to your reply from your engineering team.
