Hi Sandy9095, I am sorry about the situation; try releasing the static power and run the hardware diagnostics. Follow the steps below.  Switch off the system; remove the battery, ac adapter and the power cable. Press and hold down the power button for thirty seconds to drain any excess static power. Press the FN + Power which will initiate the hardware diagnostics. Let us know if there is any error code listed  Also send me the system service tag or express service code through a private chat, so that I can help you further.  Click on my username select start a private conversation and send me the details.
