Hi, I got Dell laptop from my friend. He said it's lock-up by password software maybe? And now can not turn on (battery was full charge). He have no idea how he gonna fix it. I think it might need new Windows install to make it work again. And another problem is...it don't have DVD drive, just USB port. I try open up the back cover it's look like Solid state hard drive in there. I'm just old school computer user and have no idea how to make it run again. We try to figure out but still no idea how to make it. Thanks for you reply.
