Wake on LAN (WOL) from Standby Does Not Activate Monitor/Video Car

[Guest]

Hi,

I have been experiencing this problem for a while now and am yet to find out
what the problem is, please help. This happens on my Dell Dimension and also
on an IBM thinkpad laptop so I don't think it is machine specific.

I am running a Windows XP SP2 PC (all security patches etc). Some times I
wish to sit in front of the PC and use it and other times I wish to control
it via Remote Desktop from the internal lan (ie no internet connection is
involved). I normally power the computer into a standby mode when I've
finished using it. When I come to sit in front of it I bring the computer out
of standby by either pressing the power button, pressing a key or moving the
mouse. Any of these actions fires up the PC and the monitor turns on. If
however I wake the PC by WOL the monitor does not "come on" and then when I
try and connect to it by Remote desktop it prompts me to login but as soon as
I login the Remote Desktop client crashes. If I wake the PC normally and then
connect via Remote Desktop it works fine.

So in summary:


- When the PC is ON I can connect, login and control the PC perfectly.

- When the PC is OFF I can send a wake on lan magic packet to wake the PC
and then I can connect, login and control the PC perfectly.

- When the PC is on STANDBY I send the wake on lan magic packet which wakes
the PC. At this point I can connect to network drives etc so the PC is on.
However if I try and connect via Remote Desktop I am prompted for the
username and password fine however as soon as I click "OK" or press enter the
window disappears and the "Remote Desktop Connection" dialog returns (asking
me which computer I want to connect to")

The exact same thing happens to both my PC and my laptop at home which both
run windows XP.

Any ideas how I can get round this problem.

Sounds like a power managment issue. Try setting the system to never power
down.

I want the system to be in standby!!! The problem is when it comes out.

Just to clarify each scenario where WOL and Remote Desktop works and doesn't
work:


Computer in Standby

Bring windows out of standby by pressing a key/power or moving mouse

• Computer powers on (fans start and power light comes on)
• Monitor wakes (led changes from orange to green) and windows desktop is
displayed

Either 1. Use computer with local keyboard and mouse
• Login and use computer as normal


Or 2. Connect with Remote Desktop Client on another PC
• Open Remote Desktop Client, type computer name and receive login screen
• Enter login credentials and windows desktop is displayed
• Use computer as normal


Bring windows out of standby by sending WOL packet from internal LAN

• Computer powers on (fans start and power light comes on)
• Monitor DOES NOT wake (led STAYS ORANGE), NOTHING is displayed

Either 1. Use computer with local keyboard and mouse
• MUST press a key or move a mouse to “activate†monitor
• (Monitor wakes (led changes from orange to green) and windows desktop is
displayed)
• Login and use computer as normal

Or 2. Connect with Remote Desktop Client on another PC
• Open Remote Desktop Client, type computer name and receive login screen
• (Monitors still NOT activated when looking at computer)
• Enter login credentials
• Remote Desktop Client CLOSES (crashes?) with NO error message/warning or
prompt
• It is IMPOSSIBLE to control this PC remotely


Computer Off

Powering on computer from off by pressing power button on front

• Computer powers on (fans start and power light comes on)
• Monitor wakes (led changes from orange to green) and bios/windows boot
screen is displayed

Either 1. Use computer with local keyboard and mouse
• Login and use computer as normal


Or 2. Connect with Remote Desktop Client on another PC
• Open Remote Desktop Client, type computer name and receive login screen
• Enter login credentials and windows desktop is displayed
• Use computer as normal
