I am using a PII-233 Mhz with R440LX dual processor motherboard & Windows 2000 professional OS. But if I don't operate the PC for 2-3 Hrs it goes in suspend mode & all the Keyboard LEDs start blinking & after hitting the space bar or touching the mouse the monitor screen comes back but I can't type my password the LEDs continues to blink, I can't even reset the PC by pressing the reset button the only option is to power off & again switch ON the PC. So what could be the reson for this? Can anybody help me out?

You didn't mention how long this has been happening. Has it always happened or is this something new? Have you changed any other components just before this started?

Nonetheless, it sounds like a power issue.

Intel recommends at least a 275W power supply be used when integrating the R440LX serverboard.

In addition, Intel further states that the integrator or system manufacturer will need to ensure the chassis (case) meets airflow, thermal and other considerations.

This is a dual processor board. Are the processors identical? Intel recommends that they be identical processors.

These Intel requirements were found at the following link:

(REMOVE SPACES from the pasted URL.)

There are further links to technical specification issues and other known issues with that board.

Here's another interesting issue:

To disable chassis intrusion on the Intel? R440LX Server Board, move the chassis intrusion detection jumper from its default position of 9-10 to position 10-11. By default, chassis intrusion is enabled. It should be disabled when integrating the R440LX server baseboard into a chassis that does not have a chassis intrusion sensor. The Intel? Columbus II Server Chassis does contain a chassis intrusion sensor.

Another interesting issue:

After updating the BIOS in an Intel R440LX, system fails to boot or takes forever to boot.

Some new systems monitor the output from the power supply and may disable features or won't boot at all. The BIOS update may tighten the tolerance on the power supply, making a previously acceptable power supply, out of tolerance.

To avoid this problem, the power supply being used should be verified as being on the Intel Approved list. Power Supplies that are notapproved for use, may actually be inadequate for the task in some systems.

Ans, speaking of BIOS, this board was produced and tested before Windows 2000 was released. There may be a BIOS update to accommodate new requirements for Win2k.

Well,I'm out of ideas. Hope I was able to help.

ok this is the same one as before so i will give you same answer. all lights on kbd flashing is bios password. when system goes into suspend it locks bios pwd. when returning you must type bios pwd first this will unlock the kbd and when unlocked you can type in os password. the lights flashing is the key to this they flash on unattended start or if bios pwd is called during operation an example of how to invoke it on some machines is ctrl+alt+L try this to see if you regain control.

good luck!

When the Beta 3 of WinK was released I attended a meeting hosted by Microsoft. One point that was emphasized over and over was that it absolutely will not work with any but the latest ACPI version, and any motherboard not supporting this would experience unreliable behavior. A PII-233 most likely does not, as it was old news well before that meeting. A couple of things you might try include checking with the MB manufacturer for a BIOS update, disable all power management in SETUP, and/or disable all power management in Win2K. One of these should improve the situation, but my first choice would be to buy a new MB - Think what you could do with a dual P4-2GHz board!!!
