Question about E-Machines eMachines Desktop PC
I was given an Emachine T2542 that went out. It won't power up and flashes yellow around the power button and the other light on the front but no fans. I unplugged everything from the power supply and individually started plugging them back in starting with the P1 (motherboard). This allowed the fans to start up. Once I got to the P8 (4 prong that attaches to the motherboard) the fans stopped. I'm not sure what this is for. I was told that the flashing lights could either be the power supply, power button or motherboard. I tried installing a new power supply but it did nothing at all, even when I plugged them in one at a time. The fan started when we did the paperclip test in 14 and 15 of the motherboard connection so it apparently works. What do you think it could be?
I would also suggest that the battery in the motherboard be replaced.That battery is startup power for the computer and if the battery is dead you will have the same symptems of startup power problems!!!The battery you will be looking at looks like a large watch batteryand is flat slide the old one out and replace it with a new one and it should solve your issues!!!

Did some research and found this site which will tell you which pins to test. It is possible also that its not powerful enough for the devices you have. I would try again only giving power to the motherboard pins, of coarse and the hard drive. If works then plug one device at a time.
