I have a Compaq Presario CQ61-212TU and my nephew wash mashing the keys and zoomed the screen so big that i can only see a few icons and the mouse only moves around the top left quadrant of the screen how as if blocked by an invisible barrier. I tried short cuts like ctrl 0 and - and to reduce the screen resolution. I even uninstalled my video driver, and when i logged in again it was OK but when i reinstalled it it zoomed in straight away... PLEASE HELP!!!

Try opening your browser, hover your mouse pointer anywhere in the web page, hold down the ctrl key on your keyboard and scroll forward on your mouse.

Holding down ctrl and scrolling with mouse is how to zoom in windows.

a machine that new I would defiantly take it back and have it either fixed or replace, time is on your side i would take advantage of the manufacture warranty. i would also look on the keyboard see if there is a mouse locking feature, its normally the picture of a mouse on one of your function keys, press function and the key with the mouse icon on it and that may take care of it.

How are you connecting the "big monitor" to your laptop? It is probably that the resolution your widescreen laptop is using is not supported by the "big monitor". Also, once the monitor is connected you may have to press a few keys to get it to display on the big monitor. You will need to press the FN key located next to the windows key and the other key that is associated with changing from the laptop screen to a monitor.

Has the screen been turned off? By turned off i mean by using the "fn" key and one of the "f" keys i believe its possibly the F5 or F8 the key will have a picture of a screen on it. My nephew did this to my compaq it took me weeks to fathom it.

Dear friend don't worry its so easy thing. You have functional in in your keyboard. Its called "Fn"
Press FN+F12 Key for turn off/on scroll function .
Thanks & waiting for your reply.

hook up an external wheel mouse, then hold control while rolling the wheel towards yourself.

ok this a little trick but it can be done first under handy capped users there is a on screen keyboard get this up so you can used mouse to operate key board for a few miinutes. then there is also a setting for sticky keys get this turned on then mouse over to cap locke on screen and turn off the caps lock. I hope this hepled you i have been in that position my self.

When you first turn the laptop on, wait for the Compaq screen to go then press F8 a few times.
A Windows Start screen will appear
Select "Last Known Good Configuration" and press enter twice.
