    I was saying that my theory is that this functionality is broken or being bypassed on Windows such that when it gets hit by for instance the Network Discovery or “Do you have this update already downloaded?” ping from another Windows computer it wakes up to have a chat. I meant other systems are looking for active machines and those pings are waking it up or keeping it from going to sleep. I may have chosen a bad slang since ‘ping’ is a net command.

    This theory is based on my understanding that computers don’t go all the way to sleep anymore and reenabling S3 restores normal sleeping. I included WoL because I have a machine that doesn’t have the S3 option but disabling WoL seemed to help on that one.




  • I have had some luck disabling Wake-On-LAN on the systems that don’t need it, or enabling higher sleep modes on the systems where that is available. My pet theory is that a lot of systems are constantly looking at what is active on the network and those pings are keeping the machine awake.







  • The other commenter is on the right track but the chip controls both USB and PS/2 as well as others;

    In the 90s and 2000s, for x86 machines, slower I/O was handled by a chip called the Southbridge which worked in conjunction with a chip called the Northbridge that handled faster I/O like IDE and PCI. Later these were integrated into a single chip and, as of recent processor generations, into the processor itself.

    AFAIK ghosting and key rollover are issues when using PS/2 but it can offer some milliseconds off latency when used in high cpu games.


  • You may be right about the copyrights in the individual unit, but I was talking about the underlying car OS in response to the commenter who said “most car systems run android”. QNX is a real-time operating system which is required for something like a car. Another for instance would be Microsoft Auto which Ford used before switching to QNX.

    In general a modern car will have dozens or hundreds of computers running their own software and communicating in a sort of API fashion usually through something like CAN bus. Most of these systems can’t afford to wait on something to boot when you start your car.

    In very general terms we are talking about the main difference between an Arduino and a Raspberry Pi.
