I need to buy a laptop because there is a massive electricity crisis in my country. Electricity goes after every 1 hour for 1-2 hours and I don't think this condition will change any time soon. Under such conditions I can't continue to work as I am working on several new and old projects and this condition is preventing me to reach my target. My Budget: $500 I just need it for simple tasks like surfing internet, running a few simple programs. Give me some suggestions.
