Navigating BIOS by Braille can be fun.
If you know what you're looking for in the BIOS you can find a manual on the HP support (http://support.hp.com) website which'll give you steps to get there in the BIOS, then just follow those instructions pretending you're blind.
Even better, if you know someone with the same type of system, you should be able to boot them side-by-side and do exactly the same thing on both systems, just pressing F10 at the end of the process on your laptop to save the changes, and ESC on the other system so as not to mess them up.
pound the F keys, one of them opens bios :) – sealz – 2012-02-24T21:48:04.640
