Answer to "Can I upgrade my Surface Pro 7 Processor?"Unfortunately not. The only “upgradeable” product in the Surface line is the Surface Pro X that has an accessible slot for upgrading the RAM (And inserting a sim). You can ensure you performance is at its maximum by ensuring your power options are set to the best possible settings (Note: this is at the cost of battery life). Click on the battery icon on the right side of the task bar, then ensure the “Power Mode” slider is moved all the way to the right side for “Performance”
Answer to "Where can I buy a new cord for my google mini"It uses any standard “micro usb” charge cable and charge port. Take a look at the end of the cord and I bet you’ll find one that matches that within your house. You can then plug that cord into any standard USB outlet. The only thing that MIGHT trip you up is if the cable you find has a base that is too wide to fit within the device’s small opening. If you find a cable that does not work, just make sure it’s fully seating.
