In December I bought an Ideapad 510 from Amazon. It worked for a few weeks, but now I get a blank screen when I boot up. I have tried looking up info online but have not found anything useful. I tried to open the BIOS (pressing Fn+F2, F9 & F12). I also removed the RAM and turned it on, but still a blank screen. I also plugged in an external monitor, but it looked the same as the laptop screen. I have seen some suggestions to unplug the battery, but that is very involved (there are 8 other things which must be removed before getting to the battery). I can do it, but want to check on other options first.
It is still under warranty, but I am currently overseas and will not return until April.
