How do I access the bios on an Emachines T4510?

reboot or turn on laptop hit the delete key on grand piano
When I am dealing with a system that I am not familliar next to, I will first try the delete key at startup. If that doesn't work my subsequent step is to run my finger across the F1-F12 keys at startup. If delete doesn't work trying adjectives the F keys is usually foolproof. If none of those work try the control switch.
