Powers on then off

The Operating system maybe corrupted but your files are still good. Try to run a system restore and before the date you notice the system fails to start.

Look at the top right hand side of the keyboard. See if the NUMB LOCK and FUNCTION LOCK keys are lit. If one or both are lit hit the key to unlock it.

Pressing the WINDOWS KEY and the letter U will bring up ease of access window. Down the list you'll see use without keyboard and mouse. Click there and make sure it is not check marked. You may also need to turn off STICKY KEYS and FILTER KEYS and hit save to unlock it.

Try pressing the WINDOWS KEY and the letter L at the same time and see if that doesn't unlock it. If that locks it instead of unlocking it press it again to unlock it.

If none of these fixes the problem then UNPLUG the laptop from the adaptor. Turn it upside down and remove the battery. Wait one minute then put the battery back in. Reconnect the power supply and reboot the machine.

It will be from the charger!
Change the charger.
Hop it helps

If it works, yes you can. It maybe that the battery went dead.

Try removing the battery for 10 minutes and put it back and see if the laptop powers on. If it doesn't, connect the power cord and see if it is charging. If not, then most likely battery is dead.

You can buy batteries from stores like ebay.

remove battery, press and hold power button for 5 seconds, then wait 5 minutes, put battery back in securely and try again. If it powers on, try and look at the power meter to see if it is registering the power supply. You could have faulty memory chip or faulty power supply

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.

can you go into control panel and look under power options? there you will see power meter on one of the tabs. click on it and see if you see if the battery is charging. if its not, there might be a problem with your power supply, the battery or the motherboard that controls the charge.

one of the ways to check if the power cord has problems is removing the battery and leave the power cord connected and see if it powers up normally. If it does, then remove the power cord and use the battery to do the same but leave the laptop on until the battery is totally drain and shuts down. try to turn it on a few times just to make sure battery is drained. then plug in the power cord to see if it charges your laptop. if all works then what you might need is to update your laptop firmware

Try reseating the memory and if that doesn’t work, install the 512’s one at a time to see if one might be defective. If the laptop still won’t turn on, reinstall original memory and see if laptop powers on.

try to take out the battery and plug it into the wall and turn it on to see what happens.

if it powers on its a probably a battery issue,
