Flashing Keyboard LEDs

[Berndusa]

I am not sure if this is the right forum to ask my question. Excuse me if I am in the wrong forum

I upgraded a system to a ECS P4S5A/DX+ motherboard with a P4 2.26 GHz CPU. I selected the ECS P4S5A since it used both SDRAM and DDR memory. I was trying to save money by reusing SDRAM and power supply from an older system. The P4S5A motherboard does not have a 12v connector for P4's. That raised a red flag from the start. The power supply was a generic 250W power supply. The bare bones system was predictably unstable and the system repeatedly locked up with blue screens. I replaced the power supply with an Enermax 350W power supply. Before I replaced the power supply I experienced a problem with the cap lock, num lock, and scroll lock lights (LEDs) on the keyboard staying on and flashing after the system powered down. I was hoping a adequately powered system would correct this problem. It did not. Did a component short out on the motherboard as a result of under powering it or is the symptom desribed a result of a some other problem?

I don't think it's indicating a problem, I have a system that works perfectly where the power light flashes when it's powered down. I think it's just a way of letting you know the system is "ready", ATX systems don't actually turn off all the way.

Are you powering down or hybernating?

I've seen the keyboard leds stay on in systems that are in hybernation mode.

RE:Teq - The LED's flashed for about a minute then stayed on after the system powered down and was off.

I tried another keyboard and the LED's turned off after the system powered down. I think it may be the keyboard. It would be the second discount generic keyboard to fail. Both the exact same model. Time to get a name brand keyboard.

Re: Crashman - I didn't realize that an ATX power supply doesn't power down or turn off completely.

Thanks for the replies.

the keyboard was going to be my second suggestion
