Lenovo P51s (Type 20HB, 20HC) Laptop (ThinkPad) - Type 20HB 8GB RAM 500Gb HD.

This laptop hard drive was wiped and Windows 10 Pro was loaded. Updates were being done - after a reboot it would not come back up. The power button flashes but the laptop will not boot back to Windows. Could be a corrupt BIOS? Not sure why it won’t boot. Screen is good. Comes with 8GB RAM and a 500GB Hard drive. Power adapter included. The removable battery is slightly swollen and will most likely need replacing. Please be aware before buying this laptop will not boot to Windows. Please see my pictures and let me know if you have any questions- thanks
