I have a Samsung Series 7 Chronos. Last week, I plugged in my charger and my computer went black and wouldn't start back up. I bought a new charger and tried that but it didn't work also. The charger I was using before was damaged from an end, so it might create that problem. I want to ask that can (a computer repair company) people help me to fix this issue also? I have heard that they provide support to software related problems only.. Any suggestions plz?
