Trying to repair a defective Netbook

Tweet

My sister in law approached my husband asking to repair her netbook because it has no power at all. My husband was busy so I decided to repair it myself. I did some diagnostic approach to test the netbook but still no sign of recovery. So, I decided to open it to see the inside and to my surprise there were a lot of dusts and some were already covering the ICs in the motherboard. I carefully cleaned it up crossing my fingers that it will now turn on but still, no sign of power. I'm sad because I wasn't able to repair it. I was thinking of repairing it and give it as present in her birthday but I was unsuccessful. Is there anyone here who knows how to repair no power in netbooks? UPDATE: Picture attached was the inside of the netbook after removing it's casing.
