Remove the main battery and try to power up, if it works replace the battery, no change! remove one stick of ram memory and repeat keeping one stick at all times, if none of these work the problem is more than likely the motherboard.

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.

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.

Turn it on, then hold the power button for 4 seconds until it forces off. Turn on again.

Otherwise, turn on, remove battery, insert battery, turn on.

Please rate.

Probably needs a new battery, simple to remove, there should be a little slider on the bottom of the laptop that u flick accross and the batery will come straight out :D

Sounds like your hard-Drive is not reponding.

REMOVED BATTERY AND CHECK ONLY IN AC MODE
IF ITS START PRESS F8 AFTER BOOTING AND OPEN IN SAFE MODE

Hi,
It is a display problem.Better to take any nearest service center.

try rundown the battery 3 times if still not holding charge your battery is faulty you have to replace it.
