hola la batería de mi Surface Pro 4 no funciona, se hincho y esta afectando a la pantalla. Donde lo puedo reparar?

Sorry, it cannot be repaired. And Microsoft no longer offers out of warranty exchanges for Surface Pro 4's. You should stop using it and back up anything stored only locally on this device. Please see Caring for your Surface battery - Microsoft Support - in particular "When batteries experience excessive aging, you may see severe battery life reductions or advanced expansion of the lithium-ion cells. Under normal conditions, Surface devices are designed with a mechanical enclosure to contain battery expansion. Under extreme conditions the battery may expand beyond the mechanical limits of the device and result in deformation.

Advanced battery expansion caused by excessive aging does not present a safety concern and is most often caused by the formation of non-flammable carbon dioxide (CO2) gas. If you have a device where the battery has expanded visibly beyond the mechanical enclosure, we recommend you stop using the device. You should handle the device with caution to prevent putting pressure on or risk puncturing the battery cell."
