Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then -
The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty.
Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced.
If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard.
This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.
Yes you should be able to upgrade the processor on the laptop for a faster one. The socket type of the processor is socket PPGA47. This code is what you type for when looking for a faster processor. The installed processor should be Intel Pentium T2390 / 1.86 GH.
As for the graphics card then i'm sorry but the graphics chip is part of the motherboard and cannot be upgraded.
The problem is your power supply charger, or the DC jack in the laptop, or bad battery. Remove the main battery and see if it will start up, if yes! the battery will need to be replaced, If no! plug charger in the computer and apply side-way pressure on the DC jack "not to hard" and press power repeatedly to see if you can start it, If yes! It is the DC jack that has broken free from the motherboard, If no! It is the power supply or motherboard. I suggest a computer tech
try removing the batteries for a minute and put it back. try to power it up again. it happened to me may times now, and i hope it will work with yours also. try it...

Do the following:
-unplug adapter from the wall -unplug from the computer side -remove the battery -With everything unplugged and battery removed, press the power button. Keep holding it down for 15 seconds Yes, nothing happened, that is ok. :) -re-insert the battery first -plug the adapter to laptop side first -plug adapter to wall socket Now, turn on the laptop and see if it powers on.
uninstall driver then turn off the PC then unplug the power cord from power socket, short its legs then leave it unconnected for 5min, then reconnect it to power socket and turn on PC and install driver it should work :)
