Hello,
Firstly, I'd like to clarify that this is a Microsoft community, where we primarily focus on Microsoft products. Since the Nokia Lumia 800 is a Nokia product, it falls outside our main scope. However, I'm happy to offer some general advice that might be helpful.
- Charging Equipment: It's possible that the original charger or cable might be faulty. Try using a different charger and cable, ensuring both are compatible with the Lumia 800.
- Physical Inspection: Inspect the device for any signs of physical damage, such as cracks or water damage. This can often be a cause for non-functionality.
- Professional Repair: If none of these steps work, it's possible that the internal components of the phone are damaged. In this case, consider taking the device to an authorized service center for professional diagnosis and repair.
Best regards,
Karlie
