Dell Laptop - E5450 not working for parts

Was working fine, then one day wouldn't boot. Took it to local repair shop, their diagnostic reported short on the mother board preventing boot up. When the power button is pressed, the power button light comes on for around 20 seconds then goes off. No fans no screen. Laptop is complete with ssd ram charger, Windows 10 installed.genuine activation has microsoft office 2007 installed. Its fairly presentable. Keyboard letter B not working. I cant access bios, O/S I cant tell you much else about it.
