SSD

It takes a SATA SSD.

None of the 3 machines in the reports runs an NVMe drive, and they have a SATA controller, so the drive is SATA. Laptops with SATA drives take either a 2.5-inch drive or, in thin models, a small mSATA or M.2 SATA card. Check the drive you have before you order.

Charger

Match the label on your charger.

We don't have this model's charger rating yet. The label on your charger shows it: the output line gives volts and amps, and volts times amps is the watts (19.5 V at 3.33 A is 65 W). Buy one with the same plug, the same voltage and at least as many watts.
