bought the lap top 6 weeks ago. has worked perfectly with brilliant 4 hour life on the battery. Yesterday I couldnt power up. tried 70+ times.... I did reset, (( removed battery and power cable, held down power button, put battery and cable back in and it started on the 3rd attempt)) would not start without putting battery back in... turned it off and happened again... Today it took 3 hours to get it on, Ive been reading loads of help pages, but have noticed , if I close down to SLEEP and not SHUT DOWN it opens every time, I tried to shutdown again and it took 30 odd goes after the reset to open up and as soon as it has opened, it runs perfectly. can anyone help???
