Hello out there!
I have the Dell 15 3521 and it's dead. It won't power on at all. This happened out of the blue in July. It just turned off and hasn't powered on since.
I took it to a local computer shop who told me they could recover my hard drive for quite a bit of money and I told them no thank you and brought it home. I don't know if they had it powered on somehow (I'm thinking they had another battery they used) to come to the conclusion that my hard drive was toast or not.
I've tried the suggestions here about holding the power button and all that but one thing I did notice, the power cord light goes out when I plug it into the laptop.
If I move the cord around on the power supply I will get a light flash of light from the power cord, but it won't stay on. It will stay on if I don't have the laptop plugged into it though.
I have plugged the cord in now with the battery in and with it out and no power either way.
Is there anything else I can do short of buying a new battery and power cord?
Thanks so much for any advice!
