Power Lights on the keeboard staying lit
trbates Jul-16-01 10:48 PM
I recently built my Dad a new computer and had bought a new case with a 300 watt power supply. Everything works great, however when you power down the computer the keyboard lights stay lit... the power and even sometimes a Num Lock or Caps light will stay on.

Any ideas as to what is causing this... or if it is causing problems...

I don't think it is shutting down. Do the CPU and power supply fans turn off? I need to know what version of windows is installed. Larry

Sorry , should have gave you all that info...

yup, the CPU and case, and even power supply fan are turning off. Its just the keyboard lights that stay on. I've even had two different keyboards connected to the computer and both stay lit after the computer shuts down.

I am running Win98.

Another interesting thing that i just remembered is that when you plug in the computer to a surge protector or a Back-UPS the fans spin alittle like it powering on then stop. But it is less then a second that they spin.

Thanks, and sorry for not posting this info earlier

The motherboard is a ...

TYAN TRINITY KT S2390B SOCKET A AMD ATX MOTHERBOARD - 200/266 FSB, ATA 100

with an AMD 1 GHz CPU, 512MB PC133 RAM, 61.4 Maxtor DiamondMax HD, 56K US Robotics Modom (old one hehe) and a Sound Blaster 16 PCI Audio Card.

1-L. Power Management (JP18)
STR is part of the ACPI system, which provides energy saving functions for the
computer. If this jumper is set to NOT ENABLED (close pins 2-3) which is the
default setting, the system will default to S1 state, even if the BIOS has ACPI
functions enabled. If the jumper is ENABLED (close pins 1-2), and ACPI functions
are enabled in the BIOS, the system will go to energy saving S3 state (hibernation),
saving the system’s state into volatile memory.

How is the jumper set? What happens when it is changed? Larry

Anything else you think i should try?

Thanks

…Another power supply, if you have one handy. I do not physically install power supplies to test for a faulty one, if the cables are long enough to connect it. You may not need to apply power to the drives. Make sure it is set to the correct power: 110 or 220 volts. Remove the power cable form the existing power supply and all disconnect cables coming from it for it before doing this. Larry

ok thanks, ill give that a try also.

Do you think that this "standby" state (or at least that is what it seems to be) is hurting anything?

I agree with your prognosis and doubt that it is hurting anything except your electric bill and it probably isn't denting that much at all. I have an EpoX motherboard and it has a jumper that allows powering-up the computer by pressing one or two keyboard keys. The keyboard LEDs stay on when it is active. I have it jumpered on. See if your computer powers-up when a couple of keys are pressed. Occasionally, I have to press them more than once. Larry
