You have an issue with your memory or a memory slot more than likely.
Remove the Power Cord, Remove the Battery, Remove the cover on the bottom of the laptop that houses the memory then 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.
Start the computer.
Enter BIOS SETUP mode.
Check the "power" settings.
Your computer is currently set to be "on" after the end of a power-outage. Change it to "last state",
i.e., turn it on if was on when the power was removed, or leave it off if it was off when the power was removed. Or, change it to "stay off" after power is restored.
This will happen if the battery is flat, or near so, try replacing battery, connect up the power adapter, and leave alone for say over night, this should charge the battery. If it doesn't then you have to check, both the charger, and the battery, and replacement is the only real way unfortunately.
you can also use your laptop without the battery, just plug its power cord while using for the mean time, the battery may be has low charge to the point that it can't turn on your laptop, insert your battery then plugin your power cord to charge your battery
just the jumper position on the mother board pin 1 and pin 2 will be occupied just unplug the power cord and remove the jumper and put the in 2 and 3 then wait for 5 sec then put the jumper to original position and power the laptop
