To turn off the power save mode, from the 'start menu' type "Power Options" in the search box and press enter. This will bring up the "select a power plan" menu. From here, select "High Performance". The sleep functions should be turned of by default, but you can select the "change plan settings" link and make sure both entries for "put your computer to sleep" are set to "never" in the drop down list and if you change it select "save changes" and you can exit.
I had an Emachines W3609 that did the same thing, I changed the 350-watt power supply with a 550-watt and it still shut off, even using the newer one. I thought just the first one was bad but I guess not. It had more than enough power to power it up but nothing. And it used to randomly restart at times and then just shut off. Try and get a new hard drive maybe that will help. Good luck!
Hello derick, Unfortunately power surges have been known to have some pretty nasty effects on your computer hardware. If you turn on your power (may have to toggle the power button behind your computer before pressing the button, worth trying in each position just in case) and your computer doesn't come on at all. This means that if none of your lights come on AND none of your fans come on, then your power supply may have blown out in the surge. If this is the case then you can't even begin to try and diagnose the rest of your PC to see if it's working. You need power to attempt diagnostics on your other components. Even if you replace the power supply, there is no guarantee that it was the only thing that was ruined by the surge. I hope this helps you out derick, and wish you better luck in the future :(
