Generic reset is remove AC, remove battery, press and hold power button for 60 seconds, release, slip in battery, apply AC and try again.
Also, if there are any USB things, unplug those.
Laptop working fine yesterday, was not dropped or any power surge, etc. Clicked to restart after a Norton update. Would not restart. When press start/power button, the following light up for less than 1 second:
-- the power button,
--a small square on upper left of touchpad and
--two lights on lower left corner of bottom part of laptop.
If hold down power button, these lights will continue to briefly light up and go out, accompanied by a small click from the speaker.
Have removed battery, and put back in, battery was fine yesterday. Have tried it with no battery and AC power source. AC power source fine. Any ideas would be welcome.
