    It is a laptop. Brand new. The first suggestion is not possible. Is there a settings menu I can find in the computer. I can barely see on this machine.

First are you using battery power, does it brighten when plugged in ? Go to the Taskbar Notifications Area look for the battery/power Icon right click choose Power Options click openPower Options, you will fid your Power Options located here, Your laptop probaly is defaulted to Power Savings, I use High Preformance, change them to your preferences, REMEMBER, There is a reason the laptop dims on battery, to save energy and extend battery between charges.

SOURCE: Fn/hot keys aren't working on my Toshiba Satellite M35.

Both of your answers can be fixed by using the hotkeys built into your keyboard.

Download and install this:

then this one:

That should do the trick.

SOURCE: Function Buttons are not working in conjunction with (FN) Key for Screen light adjustment and other features.

As far I know FN keys are related with specific motherboard drivers.
Thoshiba recovery cd/dvd during restore/re-install, loads all toshiba drivers and utilities for operating fn keys.
If the operative system loaded in the laptop is no OEM then you will have this problem, and in order to fix it you must:
First install the operative system (clean install)
Second install: chipset drivers. This drivers instructs the operative system how to detect specific hardware. Must be installed in first order.
Third: install drivers (ethernet card, audio, video controller, toshiba utilities, etc). At this point verify all FN keys ( check display settings, stand by/ hybernation, etc).
four: Load all software needed (microsoft office, etc).

I hope this help to solve your problem

Just download this :) It will fix your problem. If it doesn't work, just search for Toshiba Value Added Package Vista/XP (that depends on what Operative System you've got) and download for your Operative System.

I need to know what the keys f1-f12 keys usage.


The uses for the function (f1-f12) keys varies based on which program you have open at the time. Different programs use them for different things.

However, your computer also has some default uses for these keys when combined with pressing the fn (function) key.

fn + f1 locks computer

fn + f2 changes our power use profile

fn + f3 puts the computer to sleep

fn + f4 puts the computer into hibernation mode

fn + f5 changes the display/output mode

fn + f6 decreases the screen brightness

fn + f7 increases the screen brightness

fn + f8 enables/disables wireless connections

fn + f9 enables/disables the touch pad

fn + f10 turns the cursor overlay on/off

fn + f11 turns the numeric overlay on/off

fn + f12 turns scroll lock on/off
