For that you need to reset all settings of motherboard to defaults if it is not power up and not give any display.
Open back cover of laptop then you can find motherbord there.
Pull cmos cell from motherbord for 10 minutes then all settings goes to defaults.Also refix RAM memory.
Then whenyou power up the laptop press continue F1 or F2 or "del" key to enter in bios thne load optimal defaults then check.

My function keys doesn't work in my laptop toshiba satellite c660-a047


The function key, labeled "Fn" and located in the lower-left corner of your keyboard, is a useful feature. By pressing "Fn" along with one of the numbered function keys at the top of the keyboard (F1 through F12), you can adjust your screen brightness, enable and disable your touchpad or wireless modem, lock your computer and complete a variety of other tasks. These keys will not work if the "Fn" key is not pressed along with them. While the "Fn" key itself does not turn on and off, there are settings that can make it behave differently, or seem to be disabled.

Click "Start," then "All programs" or "Programs," then "Toshiba." Select "Utilities," then "Accessibility." Place a checkmark in the box to make sure the "Fn" key will work whether you press it simultaneously with the F1 through F12 keys or immediately before pressing those keys. Customize the other options on the screen, then click "OK." Test your "Fn" key. One of the easiest ways to do this is by pressing "Fn" and "Esc" at the same time. This toggles the sound on your computer on and off, and will show a speaker icon on your screen if it works. Press "Fn" and "Num lock" at the same time if the "Fn" key still does not work. Use the "F11" key if your laptop has no "Num Lock" key. Test the "Fn" key again, using the same method as in Step 4. Locate a licensed repair technician if the key still is not working. A hardware issue may be at fault. Hope this helps.

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

I need an explanation as to the secondary function of the keys on my NB305. Mainly the top row of 'F' keys, but the remainder of the keyboard as well. What do all these little symbols on the keys mean?


F1 through F12 are called function keys because they execute programmed functions when pressed. Used in combination with the Fn key, keys marked with icons execute specific functions on the computer. The function executed by individual keys depends on the software you are using.





1. Sound Mute: Pressing Fn + ESC in a windows environment turns sound on or off. Press Fn + Enter to simulate Enter or the enhanced keyboard's numeric keypad. 2. Instant security: Press Fn + F1 to blank the screen to prevent others from accessing your data. To restore the screen and original setting, press any key or press the Touch Pad. 3. Power save mode: Pressing Fn + F2 changes the power save mode. 4. Standby: When you press Fn + F3, the computer enters Standby. 5. Hibernation: When you press Fn + F4, the computer enters Hibernation. 6. Display selection: Press Fn + F5 to change the active display device. Hold down Fn and press F5 again to change the device. 7. Internal LCD screen Brightness: Pressing Fn + F6 decreases the display brightness in decrements. 8. Internal LCD screen Brightness: Pressing Fn + F7 increases the display brightness in increments. 9. Wireless setting: If your computer has both Bluetooth and Wireless LAN functions, you can press Fn + F8 to select which type of wireless communication you want to use. 10. Touch Pad: Pressing Fn + F9 in a windows environment enables or disables the Touch Pad function. 11. Press Fn + F10 or Fn + F11 to access the integrated keypad. When activated, the keys with gray markings on the bottom edge become numeric keypad keys (Fn + F11) or cursor control keys (Fn + F10). The power on default for both settings is off. Press Fn + F12 (ScrLock) to lock the cursor on a specific line. The power on default is off. 12. TOSHIBA Zooming Utility (reduce): To reduce the icon size on the desktop or the application window, press the 1 key while holding down the Fn key. (13. TOSHIBA Zooming Utility (enlarge): To enlarge the icon size on the desktop or the application window, press the 2 key while holding down the Fn key.

Connecting to wireless network


Not sure what kind of laptop you have, but on some models check to make sure that the actual physical "switch" is turned on. Usually located in the front or side of the laptop. Sometimes there is a little wireless logo located above the keyboard somewhere. And other times its set as a "function" key. If you see a wireless logo on a F-key (say for example F5), press and HOLD the FN key (FN stands for function, usually located on the lower left of the keyboard) and the corresponding F-key. Hope this helps!
