hi
maybe you have change the keyboard , it is failure

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.


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 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.

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.

remove the battery and adapter. press power button for 30 sec. then connect the adapter. press power button. if this didnt work. you need to ask for an help of a local tech to check for the video card and cable.
