How much should I sell my laptop for?

[HSAhmed]

Toshiba
Satellite P755
x64-based PC
Intel(R) Core(TM) i7-2670QM CPU @ 2.20GHz, 2201 Mhz, 4 Cores, 8 Logical Processors
8 GB RAM

Bought it in 2012 but still in mint condition and battery still in perfect condition
Will be installing Windows 10 before i sell it.

I'd ask anywhere from 250 to 400 bucks for it.
