What have you tried? Can you reboot? Have you tried powering off and back on? Do you have an up to date antivirus program? Are you behind a firewall? What version of Windows are you running. I'm sorry, but my dog broke my crystal ball.
I was working on the above laptop and it just stopped working. Nothing... No blue light, screen black completely dead. I checked wire to plug all ok, green light on power pack flickers but goes solid when unplugged from laptop. Plug into laptop and green light flickers on and off. Battery was fully charged at time of stopping as the laptop had been plugged into power supply the duration I'd been working on it.
Any assistance would be greatly appreciated.
