Nice long article

<div>
Thanks,<br />
It does not answer the above questions.<br />
<br />
I am especially interested in :<br />
1) The process of &quot;going to sleep&quot;.<br />
2) The process of &quot;resuming from sleep&quot;.<br />
<br />
At the moment I am interested in the system point of view.<br />
Something like :<br />
A) The OS shuts down X from now on the software can only do YYYY<br />
B) Then the CPU closes A, B, C<br />
C) From now on the software can only do XXXX<br />
D) Then the HW closes all CPU's<br />
E) From now on the software can not anything.<br />
F) the following units (ZZ + VV) of the CPU still have power in order to maintain BBBBB<br />
<br />
Something similar for the resuming process.<br />
<br />
<br />
<br />
<br />
Thanks<br />

can you please be more specific ?

Hi,<br />
I want to understand how does &quot;suspend to RAM&quot; works (on x86 systems).<br />
First of all how does it work from HW point of view. Is there a short paper/presentation/movie which explains the subject ?<br />
&nbsp; &nbsp; &nbsp;What goes to sleep ?<br />
&nbsp; &nbsp; &nbsp;What still has power ?<br />
&nbsp; &nbsp; &nbsp;What is the &quot;resume&quot; process ?<br />

Thanks<br />

Hi,
I want to understand how does "suspend to RAM" works (on x86 systems).
First of all how does it work from HW point of view. Is there a short paper/presentation/movie which explains the subject ?
     What goes to sleep ?
     What still has power ?
     What is the "resume" process ?

&quot;suspend to RAM&quot; - how does it work ?

An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. Examples of properties typical of embedded computers when compared with general-purpose ones are low power consumption, small size, rugged operating ranges, and low per-unit cost. Modern embedded systems are often based on microcontrollers; the processor(s) used may be types ranging from general purpose to those specialised in certain class of computations, or even custom designed for the application at hand. A common standard class of dedicated processors is the digital signal processor (DSP).

Embedded Hardware

Hardware includes cell phones and other digital living devices, tablets, computers, servers, peripherals and components, printers and scanners, gaming consoles, networking hardware such as routers, hubs, switches and modems, storage devices and security equipment such as firewalls and other appliances.

Hardware

A personal computer is a general-purpose computer whose size, capabilities and price make it useful for individuals, and is intended to be operated directly by an end-user with no intervening computer time-sharing models that allowed systems to be used by many people, usually at the same time. Personal computers may be connected to a local area network (LAN), either by a cable or a wireless connection, and through that to the Internet. A personal computer may be a laptop computer or a desktop computer running an operating system such as Windows, Linux or Macintosh OS.
