So i got acer aspire v5-573g and it worked fine, untill i gave laptop to my local computer hardware technician to upgrade ram and install ssd.. When i got back computer it worked fine for a month, than the problem started, over the night, before night- worked- in the morning it didnt work.. Now the problem is when i press on power button, the blue led lights turn up for a second, and turns off, and if I try again there is no blue led diode turning on again.. It always fixes the problem if i remove the back cover and put it back, so im guessing there is like a switch in the back of a cover that does it or some sort of connection that gets disconnected.. I should also mention that when I turn off the system and turn it on like 5 min after it WILL WORK, but if I leave it turned off overnight it wont work at the morning, so im currently having it turned on for like 2 months now... Please help, and I currently cant give laptop to some hardware technician, becouse im abroad, and I cant currently send laptop back for warrienty becouse I bought it when I was in other state, becouse it was cheaper, and it just isnt an option right now.. Now i found a little switch on the motherboard that gets pressed when the backpanel is closed, and when its not connected laptop wont turn on, and if i press it when i removed backcover laptop WILL TURN ON, but im 100% sure there must be another trick to get it running, becouse i taped down the switch so there was 100% a connection and the problem appeared again .. .Otherwise im using windows 7 64bit, and laptop is about 4 months old so I would really like to get it going...Thanks for your help! -John
