For last few day my desktop (lennovo -K210) not starting soon after,the cpu start button is pressed,The fans just running again and again for few mins(almost 15-20 mins) after few mins the cpu(Fans) stops running...and all the lights goes off...then if the cpu-start button is pressed the computer starts....the most amazing thing is at the start-up no error shows up.....it starts normally..
And the one main event i noticed is this happen only when the computer is started after long time(8-10 hrs) of shut down...,once i got same problem as i said above and after few mins it started...just to check the problem i shutdown the computer and started again...it started at the first press of cpu "start"no delay on 2nd start-up.
I tried the following,but no use at all:
1.restored the system configuration by start-up utility
2.reset system cmos through jumper
3.changed new motherboard battery
Help would be highly appreciated,thank you
