Hello,
I have a problem with my laptop. I tried connecting my laptop to the tv using a HDMI cable, and for some reason my laptop screen turnt black and was not registering on my tv. So i diconnected the HDMI cable from the laptop and it switched off. I have tried the hard reset test by removing battery and ac cable and holding down on the power button for 1 minute. Reconnected the ac cable (not the battery) and it still won't switch on. The ac power light comes on when i plug the cable to the computer, but there's no sound, no light, nothing!!! What have I done to cause this? Have I messed up the motherboard? Can you tell me if this is repairable and how much will it cost me?
