My kids notebook.......... HP Pavilion dv2125nr - worked fine since bought. Recently, when shutdown, won't start up every once in a while. Then some more, then more, now most of the time. The lights come on, the harddrive light flickers..... then nothing, blank screen. Now same happens and the wireless model light stays on, whether on or not the modem switch is on or off. And, before shutting down this last time, he lost wireless connection. I'm trying to turn it on over and over - as eventually this usually works - but not this time. Any thoughts or suggestions?
