@ramtech35398 could be a power issue or a Software issue. IUf you still have the original battery installed, I would start by replacing that and then try again. If that does nto work you may have to

Step 1: Press volume Up button or volume Down button to navigate the Huawei eRecovery mode. If not, proceed to Step 2.
Step 2: Press and hold the Power button for more than 15 seconds to forcibly restart your phone.
Step 3: If the battery has run out, use a standard charger to charge your phone for more than 30 minutes and then try powering it on again.

If that still does not work,you may have to do a complete factory reset. Of course, you will lose all of the information that is stored on your phone (contacts, images, music, SMS etc.) For information on how to perform a Hard Reset check sites like this
