I met the same problem, and I fixed it.

For my own case, it is mainly a hardware malfunction happening at the data bus(the wide, plastic strand) connecting the keyboard to the mainboard.
I found that part of that strand was bent, so I squeezed it to keep it flat.
everything has been OK since I did that.

I had the same problem, after checking several solutions I gave up and went for some professional help at Fraserburgh Computer Service
they needed only about 15mins to locate and fit in a new keyboard and now it's all back to normal.
Sometimes it's better and easier to spend a few quids and have it fixed by professionals.

The VERY same thing started happening to me about a month ago.
I'm just very lucky that i have a 5 button programmable mouse
to fill in for some of the buttons  (i.e copy and paste function)

Oh. and my problem is also for the Evo n610c note book.
(odd.. isn't it ?)

I've ran dozens of virus scans..
that was my first thought... that it could have been a key logger..
but found nothing.. online scans.. onboard cpu v-scans.. nothing.

and now, a secondary issue has croped up,
where other key's are going off on there own..
somewhere near the upper left hand side a button
starts setting itself off.. causing drop down menus
to appear and disappear RAPIDLY and unendingly.

the only counter measure i found for that has been a swift
left palm strike..  but sooner or later its gonna break more
then it fixes :(

My laptop keyboard can't work, its locked and i cant type

This can be done by software (locking the keyboard). I'd try a hard reboot, and see if that solves the problem.

If that doesn't work, sometimes keys get stuck down and cause the keyboard to stop working, it's odd but I find pressing (mashing) each of the keys 2-3 times will often fix keyboard issues. I typically start with the common keys like the ctrl, alt, shift, space, enter, etc.

Hope that gets ya moving again.

How do i get my laptop screen thr right way up i pressed somthing and its gone upside down

You probably flipped the screen orientation (rotated it).

For some versions of Windows (XP and Vista), try pressing Control (Crtl)+Alt+Up arrow (press the three keys together). You can also try the other arrow keys with the Crtl+Alt keys. The Crtl and alt keys are both usually in the row with the space bar. On a full-size keyboard, there are two Ctrl keys on the ends of the row and the alt keys are closest to the space bar.

Otherwise, right click on the Desktop (where there are no programs or icons) and choose Graphics Options > Rotation. Another place to check is right click on the desktop and choose Screen Resolution > Orientation. This is a shortcut to accessing the display properties in the Control Panel. Click Start > Control Panel > Appearance and Personalization > Display > Screen Resolution. For a widescreen monitor, choose Landscape.

I hope this helps.

(The ctrl+alt+arrow key doesn't work on my Win7 desktop but does work on the laptop. The Orientation change from the control panel works on both.)

Letter between c and b wont work! its the paste code key also and I dont recall using it to paste anything Whmat's your problem?

Of course, it wont work because you used a wrong short cut key. The correct short cut command for copying is press the control C simultaneously then for pasting it, it should control V simultaneously. Try it again using the right short cut command. Good luck!

I found this on another website and it worked for me. Good luck.

Okay, I know this is an old question but when i searched for the same problem recently, it was the nearest I could find. So in case others are having the same problem:

The Vaio you have is a Canadian model, which has alternate keyboard drivers for English and French. The alt car key only works with the French keyboard (durr). To switch, press the LEFT control key and RIGHT shift key at the same time, then release. Now if you use the alt car key like the shift key, i.e. hold it down then press another key, you should be able to access the pink characters. To return to English keyboard, press left-ctrl and right-shift together again.

I have a MX 3200 wireless keyboard and mouse. the

The problem was that ther keyboard was encrypted for my protection. this sometimes prevents the keyboard from connecting to the receiver and therefore the computer. to stop encrypton: press the left CRTL + left ALT + F12 key at the same time. Press the connect button on the receiver (you only have a few seconds to then press the connect button on the keyboard. Press the ESC key. Now you must start the encrypton again. Install SetPoint software from after you save and run the program, then press left CTRL + left ALT + F12 keys. sometimes there is an encrytpion wizard that pops up to help you further encrypt the keyboard, but this does not always pop up. It didn't on mine. My keyboard just started working right after i re-sarted the encryption.

hope this helps others that were in my situation.

If you can not use your Ctrl, alt delete keeys before the operating system loaads, then your motherboard is the problem. Replace the mainboard, and this issue will go away. Many of these units have this same issue. However, if you can use them before the operating system loads, then reload your os or attempt to repair it using your installation cd. To use the keys before the os loads, right after the dell logo appears, immediatly hit crtl alt delete. and your system should respond. LePro DCSE

1. If you right click on the desktop and look at graphics properties, or something similar to that, then you should get a menu for your display adapter control panel. Usually the screen rotation is right there. Sometimes it's as easy as a CTRL + arrow key combination, but I'd rather see you adjust it from a menu.

2. Ctrl-Alt-Up - right side up
Ctrl-Alt-Right - 90 degrees
Ctrl-Alt-Down - 180 degrees
Ctrl-Alt-Left - 270 degrees (If that doesn’t work, try Ctrl-Shift-R)

3. If you have the intel video chipset, I believe pressing CTRL+ALT+ one of the arrow keys should fix your problem.

I think it was ctrl+alt+right, but if that doesn't work, try the other three arrow keys.

However, if that doesn't work (especially if you do not have intel video), then right click on your desktop, go to properties, and go to the advanced tab. There you should find some setting that will allow you to reverse the rotation.
