Laptop went completely dead

battery or charger is dead,or motherboard is burnt

try resetting the camera using a toothpick or a paperclip. There is a small hole on the tripod thread on the bottom side of the camera. I hope it helps.

This could majorly happen because of sp3 conflict with one of your hardware drivers
log in into safe mode and rollback the last software or hardware driver update

You could test to see if hard drive is culprit by removing the drive. This is done by removing the access panel on bottom of laptop and slipping out the drive. Once out, try turning on laptop. It won't boot up, but you should get power light on.
I suspect you will not.
If so, problem is in power supply within laptop. Fixing requires a full diagnostic check of the power supply and battery charger. I highly recommend a trained technician for that.

1. Please make sure its the router and not the laptop. can you get the laptop to scan for other networks . this is to make sure that the issue is with the router and not the laptop. 2. goto the setup again and try changing channels to 11 or 4.

If you don't have any electric functions working I would have to say that the battery is dead.  Where the lights left on last night or a door open?  You can take the battery out and take it to your local auto parts store and they can test it for you to make sure it's not dead and if it's not, then you can have them charge it for you.  Let me know if you need anything else.

the display of ur laptop has got damaged....if u still have doubt that it might be some software problem try formatting ur system.. Or else u should go for a change of display screen

My laptop had a similar problem. I left my laptop running and some time later when I went back to my laptop, it would not startup. The power light seemed to be on but the laptop would not function. I tried several things like pressing on the power key for some time without any success and also tried all sorts of alternate buttons and sequences.

I resolved the problem by first disconnecting the power cord then by removing the battery for 5 minutes. I then re-installed the battery then connected the power adapter.

As soon as I turned the power button 'ON', the laptop booted up again.

Hope this works out for you.
