Chosen Solution
I’m a computer technician I changed the memory of 1 GB of RAM for 2 GB. The Netbook started, but when I tried to start it again it will not startup, nor turn on the LEDs. I tried with battery it did not start. When I turn on the charger, I hear a soft sound as if I were passing energy What could it be? Thanks a lot for the help
The leds not lighting would normally lead me to think there is a power supply issue, but this is a laptop with an external power brick. In this case I believe you have damaged a component somewhere on the main board, most likely with ESD during disassembly. The screen lighting once after you put it back together and not coming on again supports the idea that something important blew out. Sorry bud.
Are you sure you installed the correct RAM module? Crucial 2GB DDR2-800 SODIMM Are you sure you didn’t damage one of the wires or ribbon cables as it got caught the sheet metal or screw? At this point I think you’ll need to go back to the 1 GB module to see what happens. Did it work?
