Computer won't power on, etc

By dberkefeld ·
The computer I am working at sometimes, after first being switched on, behaves as though it is in sleep mode. You have to sometimes press the reset button or switch the computer off (by holding the power button in for a few seconds)and then on again. This is before you can even get it to the stage where it checks the memory, etc.

Also, the computer runs the phone line out of the modem into a double adapter. In the back of this is the line from the other computer's modem. It looks like this:
|| (line to modem)
___||____
(other |) |= (plug goes into another
computer |) |= double adapter)
modem |) |=
plugs |) |=
in here) ---------

Into a standard one plug, two socket double adapter plugs the first double adapter, and the line from the fax machine.

This quite happily existed all together until yesterday, but now does not want to co-exist. Everything works unless the first computer is plugged into that line (the onewith the cord off th

Hi!

I'm not too sure I understand everything correctly, but it sounds like your computer might really be in sleep mode!

Or when you press button on morning it goes into sleep mode because it's allready started.

If we assume that it has to do with your motherboards wake-on-lan features, do this:

Dirty fix: This is what you do, when not using modem turn power off.

Better fix: Turn off wake-on-lan features in BIOS settings.

The wake-on-lan features works like this, if someone calls in on the phoneline your modem is on that will start-up your computer, and if it takes long enough before you come and start using it, it goes into sleep mode.

Dunno if this is your problem but check it out.

Try this:
Replace your dimm with another from a friend and see what's happening.
Second: Try to remove all plug-in cards from your computer, and start only with video.If works, then one of your card exceed the max. consumption power, and the source does not face this.(Especialy the modem card do this after a electric shoc.)
Good luck

First check the power management in the CMOS and disable the powermanagement,now try switching out the memory chips,run scan disk to check for errors.
Check the adapter to see if the connections are seated correctly,sounds like the adapter to the fax machine is being switched off, and the modem is connected to fax as primary source.Should not affect the computer being turned on.

Looks like the PC in question (let's call it PC1) is sharing modem (if it's a modem) with the other PC (call it PC2). Turn the power off of PC2 and the modem while you restart PC1. Seems PC1 checks the status of the link during POST. If that didn't do it, do the reverse, leave PC2 with power and the modem on while you restart PC1.

Enjoy!

I agree it's a power management problem. Sometimes I've had customers call me after a storm because a surge reset or messed up the bios settings. Could be your wake on lan or power management features changed somehow. Disable all power management in bios and ignore yellow exclamation mark in device manager if there is one. Win 98 First Edition has been acknowledged by Microsoft (and other system builders) to have power management problems with newer motherboards when bios power management isenabled. Disable bios power management and only use the ones in Windows.
