SONY VAIO VPCS14AFJ (PCG51111N). BIOS startup confirmed. Please refer to the BIOS screen for basic specifications. I believe the CPU is a Celeron P4600 (unconfirmed). HDD not included. HDD mount & mounting screws included. Genuine AC adapter included. Only BIOS startup has been confirmed. Other operations have not been checked. Although difficult to see on the BIOS screen, a bright line can be seen on a black background. The plastic on the right hinge is cracked. Overall, there are many scratches and stains. This is a junk item. Please use it for parts or repair. No claims, no returns.
