Cheap fast trustable laptop computer

It's that time of the month, folks.  I feel like buying a replacement laptop, yet x86-grade power consumption and non-free BIOSes are quite a turn-down.  Are there any cheap (under 600$), fast (comparable to, say, an Intel T3400), trustable (no binary blobs) laptop (screen size between 12 and 17 inches) computers out there?  Availability of 6-cell battery also a requirement.

Probably not.

Why do /prog/rider ``faggots'' always talk about laptops and other prebuilts? Desktops are modular and cheaper for the same performance, not to mention they're easier to fix, upgrade, etc. Also, the cooling is much better. Discrete laptop HSFs are terrible!
