1. **Identify the Correct Part**: Ensure you have the correct replacement charging port compatible with your Lenovo laptop models. The part number you provided, "HXC-JLE7," may correspond to the specific charging port model. You can usually find this information in the laptop's service manual or spare parts list. If you're unsure, you can contact Lenovo support for assistance.
2. **Purchase a Replacement Part**: Search for a replacement charging port without the cable using the part number "HXC-JLE7" or the specific model numbers of your Lenovo laptops. Look for reputable sellers online or consider purchasing directly from Lenovo to ensure you receive a genuine replacement part.
3. **Prepare for Replacement**: Before starting the replacement process, power off the laptop and disconnect the power adapter. For safety, you may also remove the battery if possible to prevent any electrical mishaps during the replacement.
4. **Disassemble the Laptop**: Carefully disassemble the laptop to access the internal components, including the existing charging port. Follow the manufacturer's disassembly instructions or refer to online guides specific to your Lenovo laptop models.
5. **Replace the Charging Port**: Once you've accessed the charging port, carefully disconnect it from the motherboard and any other internal connections. Replace it with the new charging port, ensuring it's securely seated and aligned with the laptop's chassis.
6. **Reassemble the Laptop**: After replacing the charging port, reassemble the laptop by following the disassembly steps in reverse order. Ensure all components are correctly aligned and secured, and reconnect any cables or connectors that you removed earlier.
7. **Test the Charging Port**: Once reassembled, plug in the power adapter and test the charging port to ensure it's functioning correctly. If the laptop charges without issues, the replacement was successful.
