Check the Fn key in your keybaord, as I remember it was Fn+F5, Fn+F6\n\nAny way\n\nIt could be disabled in bios software.

got this from toshiba's site: \nhttp://askiris.toshiba.com/ToshibaSupportSite/search.do?cmd=displayKC&docType=kc&externalId=436487xml&sliceId=&dialogID=3718588&stateId=1%200%203716820\nMy Power Meter shows 100% and my battery light is green, indicating that my battery is fully charged, but it doesn't run for very long. Why?\n\nThis can occur if the Battery and the Power Meter utility get out of synchronization.\nThe amber light may turn to green after only a few minutes, indicating that the Main Battery is fully charged, when it is really only partially charged. If this occurs do the following:\n\nCharge the Main Battery for 3-4 hours, or until the battery light changes from amber to green. Note: If the computer's battery light doesn't come on within a few moments after being plugged in, check all of your power connections and make sure that the Main Battery is fully inserted into its slot. \nRemove the Main battery for 30-45 seconds and then put it back into the computer.\n\nThe battery should now resume normal charging, and when the battery LED turns green this time, the Main Battery and Power Meter should be in sync.\nNote! The Satellite 1605, 1625, 1675, 1695 models require the unit to be turned off to charge the Main Battery.\n\n*** IRIS is a great tech support utlitity for toshiba customers***\nhttp://askiris.toshiba.com/ToshibaSupportSite/supportcentral/supportcentral.do?id=m1

well.. as for mine. i can press a blue button that says "fn" which is near the alt and ctrl button... and at the same time... at the numbers "f9" and "f10" there is the brightness control.\nso you hold down the "fn" and "f10" at the same time and it will make it brighter.\n\nfor me atleast..

hit the setup key as the logo is shown( F2 or delete), can hit both if not sure. goto VGA settings and turn it to disabled and F10 to save and exit.

reboot then change your display settings in the control panel.  if it still won't change then it has nothing to do with dos, it is your video driver that needs to be updated and installed.

replace your charger or take it into a professional or contact toshiba

Although this is not the appropriate forum for questions like this, I will take a stab at it. Hopefully you will continue to learn more about your laptop as you go along so there really is no 'finish'.\n\n1) Read the instruction manual. It will tell you how to turn your laptop on. When you turn it on, watch the screen while the laptop goes through what it needs to do to start up. This process can take seconds or minutes depending on what is set up on your laptop. If you do not have software already loaded into your laptop, you need more help than I am prepared to provide. Hopefully, you have at least the operating system loaded.\n\n2) When the start-up process is finished, you should see a relatively unchanging view of information. Exactly what you see depends on what operating system you have.\n\n3) All laptops have a keyboard, which includes some sort of "pointing device'. It could be a button like item in the middle of the keys or a ball next to the keys or an embedded flat space in front of the keys or - if it is really cheap - only four keys with arrows. For any but the last, manipulation will provide motion of an item on the screen. This item is the 'mouse cursor'. The four keys with arrows control the 'keyboard cursor'. The 'mouse cursor' is used in conjunction with 'mouse buttons' for 'right' and 'left' 'clicking'. The purpose of 'clicking' is to relocate the "keyboard cursor'. Practice is always needed to use the pointing device efficiently. 'Clicking' and 'double clicking' in different places on the screen activate applications.\n\n4) There are some keys you need to be particularly careful about. The first is the 'Delete' key. Be very sure when you use this key that you really do want what ever happens to be selected to disappear. You may have great difficulty getting back something which has been deleted. Another set of keys to be careful using are 'Ctrl' and 'Alt'. These can change the result of just about every other key. Sometimes pressing one of these by mistake changes the mode of an application so that typing text is a nightmare.\n\n5) At the end of the start-up process, most operating systems will provide a collection of small pictures with titles underneath called ‘icons’. Each ‘icon’ represents a application or file folder. The currently selected icon is highlighted. One can change the icon selected with the arrow keys or (in some operating systems) ‘left mouse clicking’ or (in some operating systems) navigating the ‘mouse cursor’ over the preferred icon. Depending on how your operating system is set up, you either ‘left mouse click’ or ‘double left mouse click’ (using your pointing device buttons) to invoke an icon (pressing “enter” works on a highlighted icon too). Whenever you open an application with which you are not familiar, investigate the 'menu' possibilities near the top of the 'window' usually starting with 'file'. This will give you some idea of what the application does and how to go about using the application.\n\n6) Another approach is to press the ‘F1’ function key at the top of the keyboard (also available in the ‘menu’ as ‘help’).  This is an excellent source of pertinent information about where your current ‘keyboard cursor’ is placed. This will take you to the ‘help file’ associated with the application. You need to investigate the nature of ‘help files’ available on your laptop. ‘Windows help files’ normally have three ways to access information: a ‘tree’ structure table of contents; a ‘keyword’ index; and a ‘text search’ option.\n\n7) You can get options displayed for the current location of the ‘mouse cursor’ by ‘right mouse click’ing.\n\nIt should take you a significant amount of time to explore and digest the above. Come back and ask specific questions when

try restarting the computer and if that doesn't work check your display settings

fn-f8 has 3 modes, internal LCD< external VGA, and BOTH.\nUsually, the interna LCD will not be capable of all the resolutions the external is, or they operate on different refresh rates...long story short, often the projector doesn't want to be on along with the LCD. Just hit fn-f8 till the projector goes back to normal.\nThis CAN sometimes be attributed to the driver though, and you SHOULD call 310-DELL and tell them what's happening to see if they can resolve it.

Try right clicking on ur desktop, \n\nselect:\n\ndisplay modes \n\ntrue colour \n\n1024X768\n\nIt depends on ur PC. This applies to a 15inch monitor. It will be different on other monitors.\n\nIf thats not the case, then your laptop is in safemode, which you can easily convert back into normal mode, by restarting and select F8 or F10.

Ok I just checked out your laptop. Through HP.com\nTo make the screen brighter while on battery. Click the "Fn"(it is to the left side of the spacebar) button keep it pressed in and now keep tapping F10 button until it is to the brightness level that you want. To lower the brightness back press and hold Fn and keep tapping F9 button until you get the brightness you want.\n\nThe brighter you set your screen when on battery. The faster your battery will be needing another recharge.\nA battery should hold at least 1:30 minutes at least at maximum brightness setting.

With some Dells, you can press the Fn key along with F7 to enable screen expansion.  I hope this works for your laptop, but if it does not, then I'm giving you the link for Dell online support.  The site was a bit fussy tonight and I could not get through, but "enable screen expansion" is the issue you want to research.\n\nhttp://support.dell.com/support/topics/global.aspx/support/dsn/en/entry?c=us&l=en&s=gen\n\nGood luck to you!

I think it's F8 not F5, I would keep hitting F8 repeatedly after hitting the power button and a menu should come up on how you want to boot up.

I had a similar problem. One of my friend advized me to go to MS dos and type scanreg /restore; I got 4 options. He asked me to select the 3rd or 4th. I did and then followed the on screen instructions. I then adjusted display setting color resolution to true color, and 600x480 to 800x600. It is working well now. Please dont ask me more. I am not a computer savvy.
