Hi all,

Can anyone help me with the following please...

I have two similar laptops, the first is a Acer Aspire 3020 and the
other is a Fujitsu Amilo 1310G.

Both were pre installed with Windows XP home and the questions I have

What is the difference between "Hibernate" and "Stand by" ?

When I go to Start/Turn Off Computer on the Acer I am presented with
the following options
1. Stand By
2. Turn Off
3. Restart

On the Fujitsu I get
1. Hibernate
2. Stand By
3. Turn Off
4. Restart

On both laptops Hibernate is enabled under power options properties.

Standby shut things down (ie: hard drive and monitor) but still uses power
to maintain what ever is in memory. Hibernate saves whatever is in the RAM
to the harddrive, also saving the system state, and completely powers down.

Oh ya, try Google, there are a lot of pages talking about the differences
between the two.

On the ACER you might try holding the control key at the shutdown menu
the view the hybernate choice. This works to view the standby choice
when hybernation is disabled (not necessarily ACER) on some computers.
The power key might be set as the hybernate choice at shutdown in power

Standby, power state S3, is shutdown to RAM.  Hybernate, power state S4,
is shutdown to disk. S3 keeps RAM alive with power, shutting down all
else. S4 saves RAM to disk and shuts down all or most power.  S3 will
remain viable for several days on battery until there is no power to
keep RAM alive. S4 should remain viable long term since RAM is written
to disk and powered down.  Both states restore the previous state of the
desktop (open apps) and pagefile.  Usually, S3 standby can be restored
with the Enter key. S4 hybernation requires the power key. Again,
depending on the computer, these behaviors can sometimes be modified in
power options.

WinXP has some strange restoration behaviors: some computers come out of
both standby and hybernation with everything working as before.  Some
lose devices. It's a crapshoot until you learn the foibles of the
computer in question.

To be fair to Microsoft, this is almost always due to bugs in 3rd party device
drivers and not Windows itself.  Microsoft provides many tools that torture
test and otherwise check drivers for possible bugs, and unfortunately plenty
of developers (even large companies) just don't bother to use them.  How many
products have you seen where the driver installation instructions include the
step of "tell Windows you don't care that the driver hasn't passed Windows
Hardware Quality Labs (WHQL) testing... but to install it anyway?"

On the Acer, holding down the [Shift] key will change the Stand By choice to
Hibernate.  Alternatively when the options appear, press [Alt] then [H] to
enter hibernate mode.
