Macbook pro 2016 15” usb ports disabled(it is now fully drained and i am not able to charge it)

It is good you are using Apple branded products with your USB-C Mac since some cheap third party peripherals and accessories can easily damage the Logic Board of these USB-C Macs.

If the battery is completely drained, then it just complicates things because even with older Macs a completely discharged battery can prevent the laptop from powering on or even charging. The laptop needs to be receiving power in order to perform an SMC Reset. A PRAM Reset requires a Mac to actually power on and you will hear a startup chime during the PRAM Reset.

Try unplugging the charger from the electrical outlet for a minute to reset the charger's internal circuitry. Also try connecting the charger to each USB-C port especially one on the other side of the laptop. Plus try rotating the USB-C charging cable connector 180 degrees upside down (try this first at the laptop connection, then try it at the power brick). I know this sounds crazy, but can work if the USB-C port is half bad and does indicate a hardware issue. Do you hear the "ding" when plugging in the charging cable (sometimes it can take up to a minute before you may hear the "ding" sound)?

Of course make sure you are using the proper charger if you have multiple laptops since a 15" model requires an 87W charger. Make sure you are using a USB-C charging cable and not a USB-C Thunderbolt cable (the latter will have a lightening bolt on the connector).

More than likely you have a hardware failure and will need to have Apple or an Apple Authorized Service Provider to examine the laptop to provide you with a repair estimate.
