My i have lenovo G580. It isn't starting.. When i press the start button the fans spins and lights up just for few seconds although didn't display anything on screen.. It remains black.. I tried every thing i could be.. I take it to the shop for several times but after 2 or 3 days. The same problem is getting repeat.. Please help. :)
What was the problem when you took the PC to the shop? After you hear the cooling fans going for a few seconds, do they keep running after you see the black screen or they stop as if the PC is not turned on?
There may be a power related issue. It is hard to tell you which part is failing but I would say that it can be a power button problem or a motherboard issue. You should seek assistance from a technician, especially if the PC is under warranty.
