My computer won't come on I think the start button is gone or hung. the supply button is green in the back of it. It won't turn on what do I do?
When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?
When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote of their pattern (1 Long or 1 Long followed by 2 Short).
Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.
Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.Maybe your memory is bad or the memory slot is bad.Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

Hello shapscomp
The blinking green light is likely your Ethernet card's LED. Is the blinking light located near your Ethernet (network) cable?
It sounds as though your power supply has failed. You may be able to purchase a replacement power supply for it.
Would you like some assistance in deterimining if that is the case?
Thank you
BJ
SOURCE: Won't power up!
I would say yes, the power supply needs to be replaced. It is a cheap and easy fix.
One thing to check would be the capasitors around the CPU. If any are corroded or bulging then the motherboard will need to be replaced.
G'luck

1.Clean the RAM twice.
2.If No display then Check with another RAM
3.If it also fails disconnect all the drives and clean the processor slots.then check again.
4. If it also fails may be problem with SMPS or Mother Board

Surge protectors blow with excesive power not with drop and return spikes, and that doesnt still promise that it will not kill power supplies and motherboards. I would suggest a new power supply as they are all standard then see if it works. If not your motherboard maybe shot if it was on while it happened.
