Haven’t used this computer for several months and when I push the button to turn it on the lights light up for several seconds but the screen doesn’t light up and no sounds are made. When I plug it in the battery charge light does not stay on but will flash periodically (every ten seconds or so) or not at all. I have plugged it in and unplugged it; I have taken out the battery and put it back in. I have stuck a paper clip in that hole above the cap lock light. I have used two different power cords (both work in my other dell). I would really appreciate any recommendations? Thank you. Renae.
