Laptop of about 1 year, will not power on when the power button is pushed. Fully charged, plugged in, not plugged in. etc. All tested and it will not turn on. Few nights ago I did get lucky and turn it on, however once only a few keys on the keyboard registered with the laptop, and the rest no matter how pushed, was not registered and wouldn't type. Other than that one random time, it just does not turn on when the power button is press, or held. Any ideas what is going on?
